This document discusses the isolation and characterization of nickel tolerant bacterial strains from electroplating effluent sediments. Sixteen bacterial strains were isolated from electroplating effluent contaminated soil and screened for nickel resistance. Six strains (Pseudomonas spp 1, Escherichia coli, Proteus spp 2, Staphylococcus spp 1, Salmonella spp 2, and Shigella spp 2) showed better growth in nickel medium. Pseudomonas spp 1 was found to be the most nickel tolerant, exhibiting best growth at 300ppm nickel, pH 7, and 37°C temperature. The document aims to identify bacterial strains that can potentially be used to bioremediate nickel contamination
Biosorption of Copper (II) Ions by Eclipta Alba Leaf Powder from Aqueous Solu...ijtsrd
The removal of heavy metals from industrial wastewater is of great concern as heavy metals are non-biodegradable, toxic elements that cause serious health problems if disposed of in the surrounding environment. The present study, Karisalangkani (Eclipta Alba) leaves were used for the adsorption of heavy metals like copper (Cu (II)) ions. The bio sorbent was characterized using SEM and BET analysis. The bio sorption experiments are conducted through batch system. The operating parameters studied were initial metal ion concentration, adsorbent dosage, initial solution pH, contact time and effect of temperature Adsorption equilibrium is achieved in 30 min and the adsorption kinetics of Cu (II) is found to follow a pseudo-second-order kinetic model. Equilibrium data for Cu (II) adsorption are fitted well by Langmuir isotherm model. The maximum adsorption capacity for Cu (II) ions is estimated to be 9.2 mgg at 25 °C. The experimental result shows that the materials have good potential to remove heavy metals from effluent and good potential as an alternate low cost adsorbent. Due to their outstanding adsorption capacities, Eclipta Alba is excellent sorbents for the removal of copper (II) ions. B. Kavitha | R.

Phytoremediation is a low cost and effective soil
treatment option for metal reclamation. The use of plants to
remove heavy metals from soil is the phytoremediation. Heavy
metals are among the most dangerous substances in the
environment because of their high level of persistence and
harmfulness to living organisms. The present study in the field
deals with phytoremediation of heavy metals from contaminated
soil around Steel industry at Boisar Industrial area, using Indian
mustard (Brassica juncea L.) plant. The impact of addition of
chelating agents like EDTA (Ethylenediamine tetraacetic acid)
and Citric acid on the bioaccumulation efficiency of the plant
were investigated. Mustard plants were grown in soil around
steel industry. The results indicated significant reduction of
metals in the soil and increased accumulation in biomass. EDTA
proved better than citric acid in extraction of metals from the
soil. Order of percentage phytoextraction by plant was Fe+2 >Cd

Nanoparticles Methods for Nanoparticles Synthesis Overviewijtsrd
Nanoparticles exist in several different morphologies such as spheres, cylinders, platelets, tubes etc. The word nanoparticles are used to describe a particle with size in the range of 1nm to 100nm, at least in one of the three possible dimensions. In this size range, the physical, chemical and biological properties of the nanoparticles changes in fundamental ways from the properties of both individual atoms molecules and of the corresponding bulk materials. The enormous diversity of the nanoparticles arising from their wide chemical nature, shape and morphologies, the medium in which the particles are present, the state of dispersion of the particles and most importantly, the numerous possible surface modifications the nanoparticles can be subjected to make this an important active field of science now a days.

Removal of Lead Ion Using Maize Cob as a BioadsorbentIJERA Editor
The intensification of industrial activity and environmental stress greatly contributes to the significant rise of
heavy metal pollution in water resources making threats on terrestrial and aquatic life. The toxicity of metal
pollution is slow and interminable, as these metal ions are non bio-degradable. The most appropriate solution for
controlling the biogeochemistry of metal contaminants is sorption technique, to produce high quality treated
effluents from polluted wastewater. Maize cob readily available was used as sorbent for the removal of lead ions
from aqueous media. Adsorption studies were performed by batch experiments as a function of process
parameters such as sorption 500ppm,2.5g, 400minutes, 400 rpm and 5 PH. Concentration, Dosage, time, rpm,
and pH. I have found that the optimized parameters are Freundlich model fits best with the experimental
equilibrium data among the three tested adsorption isotherm models. The kinetic data correlated well with the
Lagergren first order kinetic model for the adsorption studies of lead using maize cob. It was concluded that
adsorbent prepared from maize cob as to be a favorable adsorbent and easily available to remove the heavy
metal lead (II) is 95 % and can be used for the treatment of heavy metals in wastewater.

The Influence of Soil Organic Matter on the Uptake of Silver Nanoparticles in...Agriculture Journal IJOEAR
— The uptake of silver from silver nanoparticles in soil was investigated in the presence of increasing concentrations of soil organic matter. Especially, the effect of Humus component of soil organic matter on the uptake of Ag from silver nanoparticles was studied. Two insect species, Acheta domesticus and Tenebrio molitor, and two plant species, Helianthus annuus and Sorghum vulgare, were exposed to silver nanoparticles(25 ppm in the presence of increasing concentrations of Humus (0, 1, 5, 10, 15, and 20% Humus) in soil (by weight). The techniques of transmission electron microscopy, dynamic light scattering, and powder X-ray diffraction were used to characterize the silver nanoparticles used in the study. An inductively coupled plasma-optical emission spectrometer was used to measure the levels of silver in test samples. Increasing concentrations of Humus in soil has resulted in an increase in the sulfur content and cation exchange capacity of the soil. A general decrease in the concentrations of silver was observed in Acheta domesticus and both the plant species, as a function of increasing concentrations of Humus in soil. In the case of plant species, the accumulation of silver nanoparticles was predominantly observed in the root tissue. Additionally, the translocation of silver from the roots to other plant tissues was observed in the case of Helianthus annuus. Results from this study suggest that the presence of Humus in soil could possibly decrease the uptake of silver from silver nanoparticles by insect and plant species.

A Review on Applicability of Photocatalyst Titanium dioxide for Treatment of ...IJERA Editor
Greywater reuse has attracted great attention for sustainable management of water especially under water
scarcity conditions. However, the effort has been limited by the presence of toxic organics in the effluent which
in turn inhibits the public acceptance of recycling water. The existence of those organic pollutants, which cannot
be eliminated by conventional primary and secondary treatment processes, can be problematic. Hence it is
necessary to explore a sustainable, robust and affordable method for treatment of greywater. Photocatalytic
oxidation is an emerging technology that could be suitable to remove refractory organic compounds found in
greywater. Recently titanium dioxide (TiO2) gained wide attention for photocatalytic oxidation of organic matter
of wastewater. Because it is biologically and chemical inert, resistant to chemical corrosion and can work at
ambient temperature and pressure, without addition of chemical species. The irradiation of titanium dioxide
dispersions by ultraviolet (UV) (300-400 nm) light can lead to the formulation of highly reactive hydroxyl
radicals which attack the pollutant molecule to degrade it into carbon dioxide, water and mineral acids.This
technology has advantages, such as, the integration into small places, low maintenance and easy operation.

About 20 topsoil samples collected from different locations of Gazipur industrial area were analyzed
to specify the elements by XRF. Soil pH, moisture content, organic carbon, organic matter, elements were
investigated by following proper procedure to find out the actual scenario of the soil status. Most soil samples
pH is tend to neutral which is most favorable for up taking nutrients. Moisture Content, Organic Carbon and
Organic Matter are enriched in the soil for plant growth. Speciation analysis are showing concentration trend
as Al>Fe>K>Mg>Ca>Rb>Mn>Si>P. Most of the elements are used as fertilizer for soil nutrient supplement
and also used as raw material in process industries. Though they are required for improving soil quality excess
amount is also harmful for soil biota. Soil chemical reaction with the surroundingis largely controlled by the
components present in soil matrix. Multivariate statistical analysis e.g: hierarchical cluster analysis showing 2
main clusters in the soil matrix which components are similar in characteristics or source.Group 1 and 2
formed by following different factors like common sources, attraction of the elements, similarity in
characteristics. Correlation matrix is exhibiting significant positive relationship among the components.
Different components have distinct positive relation with distinct components which differ from each other.
Principal component analysis denotes 3 principal components for composing soil matrix significantly.
Health risk assessment of consuming heavy metal contaminated benthic seafood,...Premier Publishers
This study evaluated health risks associated with the consumption of a seafood (bivalve - Anadara (Senilia) senilis) contaminated with some heavy metals in southern Nigeria. Atomic absorption spectrophotometry was used for metal analysis. Mean metal concentrations (µgg-1) was in the order of Zn(12.96±1.0)> Pb(4.69±0.6)> Cr(2.91±0.7)> Ni(2.47±0.2)> Cu(2.03±0.3)> Cd(1.68±0.2). Mean concentrations of Cr, Cu and Zn were below their respective FAO/WHO recommended limits while those of Ni, Cd and Pb exceeded. The Estimated daily intake-EDI values of all metals were less than their respective reference oral doses-RFD implying minimal health risk. The target hazard quotient (non-carcinogenic) and hazard index-HI had values <1suggesting minimal health risk of non-carcinogenic origin but HI value showed potency of increase. The value of Incremental Lifetime Cancer Risk-ILCR ranged from 10-5-10-2 with Ni and Cd within the acceptable range of 10-4-10-6 while Cr and Pb exceeded the limit. The target cancer risk-TR had values of 10-3 indicating moderate to high risk according to the New York State Department of Health classification. The study concluded the presence of moderate to high carcinogenic risk due to Cr and Pb for consumers of heavy metal contaminated seafood (bivalves) in southern Nigeria. Minimal consumption and further action are advised with regular monitoring to detect changes.

This study evaluated health risks associated with the consumption of a seafood (bivalve - Anadara (Senilia) senilis) contaminated with some heavy metals in southern Nigeria. Atomic absorption spectrophotometry was used for metal analysis. Mean metal concentrations (µgg-1) was in the order of Zn(12.96±1.0)> Pb(4.69±0.6)> Cr(2.91±0.7)> Ni(2.47±0.2)> Cu(2.03±0.3)> Cd(1.68±0.2). Mean concentrations of Cr, Cu and Zn were below their respective FAO/WHO recommended limits while those of Ni, Cd and Pb exceeded. The Estimated daily intake-EDI values of all metals were less than their respective reference oral doses-RFD implying minimal health risk. The target hazard quotient (non-carcinogenic) and hazard index-HI had values <1suggesting minimal health risk of non-carcinogenic origin but HI value showed potency of increase. The value of Incremental Lifetime Cancer Risk-ILCR ranged from 10-5-10-2 with Ni and Cd within the acceptable range of 10-4-10-6 while Cr and Pb exceeded the limit. The target cancer risk-TR had values of 10-3 indicating moderate to high risk according to the New York State Department of Health classification. The study concluded the presence of moderate to high carcinogenic risk due to Cr and Pb for consumers of heavy metal contaminated seafood (bivalves) in southern Nigeria. Minimal consumption and further action are advised with regular monitoring to detect changes.

The effect of gas flaring on the rate of corrosion of metals within Egi kingdom was investigated
in this work. Surface water which has been exposed to gas flares, was taken from Ogbogu flow station in the Egi
kingdom of Ogba/Egbema/Ndoni Local Government Area of Rivers State Nigeria, and was used for this
experiment. The procedure involved soaking one set of the coupons of mild steel and copper in the water taken
from the gas flow station and another set in distilled water and kept for 14 days; after which the metals were
removed and weighed for weight loss as a result of the corrosive effect of both water. This process was repeated
for 56 days and various data obtained was analyzed using empirical correlation. Matlab was used for
computation and simulation. At day 42, corrosion rate for the flare zone water and distilled water were for mild
steel 3.332cm/days and 2.666cm/days and copper 2.562cm/days and 2.277cm/days respectively. The result
obtained showed a higher rate of corrosion for water taken from within the flare zone of Ogbogu Flow station
than distilled water.
An investigation on heavy metal tolerance properties of bacteria isolated fro...AbdullaAlAsif1
The presence of high concentration of toxic heavy metals in industrial waste directly leads to contamination of receiving soil and water bodies and has deleterious impact on both human health and aquatic life. In the present study samples from textile mill effluent from different areas of Jessore city were analyzed for the identification and characterization of bacteria which shows tolerance to Copper, Mercury and Zinc. The bacterial isolates were characterized on the basis of their morphological and physiological studies including size and shape of the organisms, arrangement of the cells, presence or absence of spores, regular or irregular forms, gram reaction, cultural characteristics, IMViC test, H 2S production, nitrate reduction, deep glucose agar test etc. All the bacterial isolates belonged to 3 genera Bacillus, Enterobacter and Pseudomonas. All the gram positive isolates used in our study showed highest level of tolerance to Zn and moderate level of tolerance to Cu while gram negative isolates showed higher tolerance to Zn in comparison with Cu in nutrient broth. But all of the isolates showed almost no tolerance to Hg. So, our bacterial isolates have the probability to use in the treatment of industrial effluent containing heavy metals and thus pollution due to heavy metal can be controlled. The goal of this study was to identify heavy metal tolerant bacteria from the textile effluent. This kind of study is very significant for broader investigation to obtain data about metal tolerant bacteria considering their potential use for bioremediation and about the interactions between metals and bacteria.

Evaluation of Cadmium tolerant Fungi in the dying Staff and their removal Pot...AI Publications
Cadmium tolerance and bioremediation capacity of seven isolates including Aspergilus versicolor, Aspergillus fumigatus, Paecilomyces sp.9, Paecilomyces sp.G, Terichoderma sp, Microsporum sp,Cladosporium sp were determined. Minimum inhibitory concentration values among 2,000-6,000 mg lˉ1proved great ability of isolated strains to survive in cadmium polluted environments. The most tolerant fungi, Aspergilus versicolor, showed tolerance index of 0.93 in 100 mg lˉ1 cadmium agar media. Fungal resistance against cadmium is depended directly on strain’s biological function. A. versicolor was found to bioaccumulation over 7.67mg of cadmium per 1 g of mycelium, followed by 6.546, 6.354, and 6.286, 6.134 by Paecilomyces sp, Aspergilus fumigatus, Microsporum sp and Terichoderma sp, respectively. It can be noted that tolerance of the strains appears to be independent from bioaccumulation capacity. Finally, the results indicated that A. versicolor could be a prospective candidate for bioremediation processes.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

Abstract— In the present study, an attempt was made to isolate and characterize nickel tolerant bacterial strains from the
electroplating effluent contaminated soil. The effluent sample was collected at the direct outlet of electroplating industry and
analyzed for physico-chemical characteristics such as pH (6.5), temperature (33), electrical conductivity (15.1 ms/cm), total
solids (2309mg/l), total dissolved solids (5573 mg/l), chloride (0.20mg/l), sodium (0.13ppm), calcium (2.23ppm), potassium
(0.20ppm), Biological Oxygen Demand (4200mg/l), Chemical Oxygen Demand (5243 mg/l) and nickel (4.063ppm).
Enumeration of total bacterial population from the electroplating effluent contaminated soil sample was made in nutrient
agar medium. Sixteen bacterial colonies were selected based on their abundance growth all of them were identified through
morphological and biochemical characteristics. All the sixteen bacterial isolates were screened for its metal tolerance using
nutrient agar medium incorporated with nickel metal. Based on the better growth performance, six bacterial strains were
selected as potential metal tolerant organism. The selected metal tolerant bacterial strains were further characterized in the
various environmental conditions such as pH (5, 7 & 9) temperature (5°C, 28°C, 37°C & 45°C) and concentration of metal
ions (100ppm, 200ppm, 300ppm & 400ppm) for 5 days. The result reveals that one bacterial strain, Pseudomonas sp 1 was
showed better growth in nickel metal based medium with pH 7 at 37°C temperature.
Keywords— Electroplating effluents, Heavy metals, Nickel, Biosorption, Pseudomonas sp 1.
I. INTRODUCTION
In this wake of industrialization, consequent urbanization and over increasing population, the basic amenities of life viz, air,
water and land are being polluted continuously. Industrial complexes have become the focus of environmental pollution
(Shukla et al., 2007). Water, the most vital resource of all kinds of life on this planet and it is adversely affected both
qualitatively and quantitatively by all kinds of human activities (Reddy et al., 2001).
Disposal of industrial and urban wastes to soil and water bodies has led to disastrous consequences in the ecosystem (Smith,
1974). Industrial operations such as electroplating, steel manufacturing, leather tanning, wood preservation, ceramics, glass
manufacturing, and chemical processing and fertilizer applications release alarmingly higher amounts of metals into the
natural environment (Zoubolis et al., 2004).
The increase in industrial activity during recent years is greatly contributing to the increase of heavy metals in the
environment, mainly in the aquatic systems (Marques et al., 2000). Water pollution due to heavy metals is an issue of great
environmental concern (Vasudevan et al., 2003).
Various sources of pollutants industrial effluents containing heavy metals pose a threat to ecosystem. There metals present in
the wastewater of different industries such as metal cleaning, plating baths, refineries, mining, electroplating, paper and pulp,
paint, textile and tanneries (Mistry et al., 2010).
Release of heavy metals without proper treatment poses a significant threat to public health because of its persistence,
biomagnifications and accumulation in food chain (Rajendran et al., 2003).
Electroplating is the most commonly adopted metal finishing process, these result in the generation of heavy metal
pollutants, which are toxic and non biodegradable. Heavy metals are generally deposited in liver, muscles, kidneys, spleen,
skin, bone and soft tissues of human beings. Heavy metals pollution is one of great environmental concerns, because the
heavy metals are non degradable and persistent in water. Heavy metals in the environment may also change plant diversity
(Zafar et al., 2007).
Heavy metals may disrupt the normal function of the central nervous system and cause changes in the blood content, and
adversely affect the function of lungs, kidneys, liver and other organs. The long-term action of heavy metals may cause the

development of cancer, allergy, dystrophy, physical and neurological degenerative processes, Alzheimer's and Parkinson's
diseases. However, in small amounts, heavy metals are indispensable for many organisms, but their enhanced doses induce
acute or chronic poisoning (Kvesitadze et al., 2006).
Nickel is generated from batteries, wire and electrical parts. Steady ingestion (exposure to nickel) can lead to cancer
especially of the lungs and nasal sinus (Hauser and Hauser, 2008). Nickel (Ni) is the 24th most abundant element in the ealih
crust and has been detected in different media in all parts of the biosphere. Ni is classified as the borderline metal ion because
it has both soft and hard metal properties and can bind to sulfur, nitrogen and oxygen groups. Ni has been implicated as an
embryotoxin and teratogen (Weber and Digiano, 1996).
Conventional techniques for removing heavy metals from industrial effluents include chemical precipitation, chemical
reduction, adsorption; ion exchange, evaporation and membrane processes. Compared with conventional methods for the
removal of toxic metals from wastewater, the biosorption process offers potential advantages such as low operating cost,
minimization of chemical or biological sludge, high efficiency of heavy metal removal from diluted solutions, regeneration
of biosorbents, possibility of metal recovery and environmental friendly (Ahluwalia and Goyal, 2007).
Most of the industrial techniques are ineffective and excessively expensive at the metal concentration less than l mg/ml
(Alloway, 1995). Microbial metal bioremediation is an efficient strategy due to its low cost, high efficiency and ecofriendly
nature (Rajendran et al., 2003).
In recent years, the biotechnology applied to control and remove metal pollution has received much attention, and gradually,
becomes a hot topic in the field of metal pollution control because of its potential application. For heavy metal removal, an
alternative process is biosorption, which utilizes certain natural materials of biological origin, including bacteria, fungi, yeast,
and algae (Alloway, 1995). With a view of this, the present study is focused an isolation and characterization of nickel
tolerant bacterial strains from the electroplating effluent contaminated soil.
II. MATERIALS AND METHODS
2.1 Collection of sample
The nickel electroplating effluent was collected from the direct outlet of Meena electroplating industry and the soil sample
was collected from effluent contaminated land near Madurai, Tamil Nadu, India and the samples were immediately
transported to the laboratory, Department of Biology, GRI, Gandhigram, for further analysis.
2.2 Physicochemical characteristics of the electroplating effluent
The physicochemical parameters such as Temperature, pH, Electrical Conductivity, Total Dissolved Solids, Total Solids,
Sodium, Potassium, Calcium, Chloride, Biological Oxygen Demand And Chemical Oxygen Demand were analyzed from
electroplating industrial effluent using standard methods (APHA, 1998) and concentration of nickel metal was estimated by
Atomic Adsorption Spectrophotometer (Konstantinos et al., 2011).
2.3 Isolation and Identification of metal tolerant Bacterial strains
The electroplating effluent contaminated soil sample was serially diluted with normal saline (85% Nacl) up to 10-9
dilutions.
Sample (0.1ml) from 10-5
and 10-6
dilutions were taken and spread on the nutrient agar plates and incubated at 37°C for 24
hrs. The sixteen predominant colonies grown on nutrient agar medium were selected and maintained as pure cultures.
All the sixteen bacterial strains were identified through morphological and biochemical characteristics through Gram’s
staining and Motility Test, Indole Production, Methyl Red reaction, Voges Proskauver reaction, Citrate Utilization test,
Urease test, Starch Hydrolysis, Catalase test. All the strains were authenticated by Bergey’s manual of determinative
bacteriology (Holt et al., 1984).
2.4 Screening of selected bacterial isolated for nickel resistance
All the sixteen bacterial isolates were screened for its potential to tolerate heavy metal using nutrient agar medium
incorporated with nickel metal (100ppm). All the plates were incubated at 37°C at 5 days. The comparative growth
performance of all bacterial isolates were observed and recorded (Jamaluddin et al., 2012; Pandit et al., 2013).

2.5 Characterization of nickel tolerant bacterial strains
Six potential metal (Ni) tolerant bacterial strains Pseudomonas spp 1, Escherichia coli, Proteus spp 2, Staphylococcus spp 1,
Salmonella spp 2 and Shigella spp 2 were characterized by growing them in the metal - based nutrient agar medium with
various environmental conditions such as pH (pH 5, pH 7 & pH 9), temperatures (5°C, 28°C, 37°C & 45°C) and metal
concentrations (100ppm, 200ppm, 300ppm & 400ppm) in various treatments for 5 days (Margeay et al.,1985).
III. RESULTS AND DISCUSSION
Microbes particularly bacteria and fungi are excellent agents for removal of heavy metals with lieu to production of metal
chelators or enzymes which convert the metals to lesser toxic forms. The ability to tolerate heavy metals depends largely on
the adaptability of the strains in a polluted environment or due to continuous exposure to the heavy metals (Volesky, 1990).
In this study, an investigation was made to study the physicochemical characteristics of nickel-based electroplating effluent
and to isolate and characterize nickel tolerant bacterial isolates from the electroplating effluent contaminated soil sample.
Bacteria have evolved several types of mechanisms to tolerate and to the uptake of heavy metal ions include the efflux of
metal ions outside the cell, accumulation and complexation of the metals inside the cell and reduction of the heavy metal
ions to a less toxic state (Nies, 1999).
The physicochemical characteristics of nickel electroplating effluent was determined and was found to contain pH (6.5),
temperature (33°C), electrical conductivity (15.1ms), total solids (2309mg/l), total dissolved solids (5573 mg/l), chloride
(36mg/I), sodium (138ppm), calcium (220ppm), potassium (2.09ppm), Biological Oxygen Demand(42mg/I) and Chemical
Oxygen Demand (5243mg/l). The nickel (1.03ppm) contents in the electroplating effluent were determined by Atomic
Adsorption Spectrophotometer.
3.1 Isolation and identification of metal tolerant bacterial strains
Sixteen bacterial colonies shown the predominant growth on nutrient agar plates were selected and maintained as pure
culture in agar slants. All the sixteen bacterial isolates were identified through morphological characteristics by staining
techniques and biochemical characteristics and the results were compared with Bergy's manual of Determination
Bacteriology (Holt et al., 1994).
3.2 Screening of selected bacterial isolated for nickel resistance
All the sixteen bacterial isolates were further screened for its potential to tolerate heavy metal. Nutrient agar medium was
prepared with pH and incorporated with nickel metal (100ppm). The medium was sterilized at 121°C with 15 lbs for 20
minutes. The results were recorded in Table 3.
All the sixteen bacterial isolates were streaked on the nickel containing agar medium and incubated at 37°C at 5 days.
Among the sixteen isolates, only six bacterial strains Pseudomonas spp 1, Escherichia coli, proteus spp 2, staphylococcus
spp 1, salmonella spp 2 and Shigella spp 2 were found to potential metal tolerant strains by having better growth
performance in the screening medium (Table 1).
3.3 Characterization of nickel tolerant bacterial strains
The six selected metal tolerant bacterial strains were characterized by growing them in the metal-based nutrient medium in
different environmental conditions and the result reveals that, Pseudomonas spp 1 was found to be better metal tolerant
organism which exhibit better growth performance in the 300 ppm of nickel based medium with pH 7 at temperature 37°C
(Table 2).
These metal tolerant strains derive their nutritional requirement from the effluent waste. They are able to synthesize their
enzymes, metabolic intermediates, structural proteins, lipids and nucleic acids from carbon compound in the feed, together
with other elements. They derive their energy from oxidizing either organic compounds (chemoorganotrophic metabolism),
or inorganic compounds (chemolithotrophic metabolism), such as reduced sulfur or nitrogen compounds. They use the
energy for their bodily functions, reproduction and growth. Many research reported that a large number of bacterial species
isolated from different industrial effluents (Zafar et al., 2007).
