Phytoremediation of soil
Phytoremediation is a process that uses plants to remove contamination from soil, water or sediments. It works by utilizing the natural biological, chemical and physical processes of plants. Plants can absorb, break down, stabilize or prevent the spread of contaminants like heavy metals, pesticides and organic pollutants. Some common plants used for phytoremediation include alfalfa, poplar trees, and bermuda grass. The advantages are that it is a low-cost, environmentally friendly way to treat large areas of land. However, it is a slower process and not effective for high concentrations of contamination.
Potential of ornamental plants for phytoremediation of heavy metals
The document discusses the potential use of ornamental plants for phytoremediation of heavy metals. Phytoremediation uses plants and their associated microorganisms to remove contaminants from the environment. It is a natural, low-cost process to remediate sites contaminated with heavy metals. Ornamental plants could accumulate heavy metals through their roots and leaves, converting contaminated land into landscapes while preventing metal entry into the food chain. Factors like plant species selection and soil properties influence metal uptake. Phytoremediation provides economic and environmental benefits but also has limitations from contaminant leaching and plant disposal.
Pesticides Degradation Through Microorganisms (Biodegradtion)
The document discusses a research study on biodegradation of the pesticide profenofos. It lists the group members and describes profenofos as a widely used and hazardous pesticide in Pakistan. The methodology section outlines the steps taken, which included sampling soil, enriching samples in media, incubating mixtures, conducting plate counts, and isolating and characterizing microorganisms. The researchers found specific growth of pesticide-degrading microbes and plan to isolate and characterize them further. The experience was positive and the microbiology lab was well-equipped to support the research.

This document discusses phytoremediation, which is the use of plants and their microorganisms to reduce environmental pollution without excavating contaminated materials. It defines phytoremediation as a natural process that can effectively remediate a variety of contaminated sites. The document outlines the advantages and mechanisms of phytoremediation, provides examples of its use, and lists types of plants suitable for phytoremediation projects.
Phytoremidiation
Phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the soil and groundwater. There are three main phytoremediation processes: phytoextraction, which uses plants to remove contaminants from soil and concentrate them in harvestable biomass; phytostabilization, which focuses on long-term stabilization and containment of pollutants using plants; and phytotransformation, where plants or associated microorganisms metabolize and degrade organic pollutants. Phytoremediation has advantages of being lower cost than traditional remediation methods and preserving the natural environment, but it also has limitations such as being restricted

Phytoremediation is the process of using plants to remove contamination from soil or water. It involves using plants and their associated microorganisms in the rhizosphere to degrade, contain, or remove pollutants from the environment. Some key advantages are that it is a cost-effective, environmentally friendly way to remediate large areas of contaminated land. However, it is limited to sites with lower contaminant concentrations and works more slowly than conventional remediation methods. Common contaminants removed through phytoremediation include heavy metals, hydrocarbons, pesticides, and explosives. The process works through plants absorbing, degrading, or stabilizing pollutants in their tissues or the surrounding soil.

Persimmon (Diospyros kaki) is grown in wide climate conditions, which may affect fruit biochemical characteristics such as vitamins, soluble solids and antioxidants. Therefore, the aim of this research is to evaluate the biochemical responses of fruit to these climate variables. For this purpose 5 districts of Kashan, Shahrud, Yazd, Kiasar and Sari were chosen to collect fruits.Phytoremediation
Phytoremediation uses plants and their associated rhizospheric microflora to remove or break down pollutants in soils, sediments and groundwater. Plants can absorb, sequester, and extract inorganic and organic pollutants like metals, pesticides and hydrocarbon compounds. The microbes in the rhizosphere also play a key role in degrading pollutants through secretions from plant roots that serve as carbon and energy sources. This process occurs through various mechanisms like accumulating metals in harvestable tissues, transforming pollutants to less toxic forms, or stabilizing pollutants to limit their mobility.

This document discusses using ultrasound-assisted vacuum impregnation to enrich potato by-products with ascorbic acid. Potato processing generates large amounts of waste that still have nutritional value. The study examines impregnating irregular potato cubes with ascorbic acid through standard vacuum impregnation and ultrasound-assisted vacuum impregnation. Ultrasound increased the impregnation efficiency but the effect depends on application time. Ultrasound also positively impacted the kinetics and energy consumption of subsequent convective drying of the impregnated potato cubes. Ultrasound did not reduce product quality based on color or water activity. The proposed technology could help utilize potato by-products in a more sustainable way.

Rapid composting of different wastes with yash activator plusSSR Institute of International Journal of Life Sciences
This document describes a study on rapid composting of different wastes using Yash Activator Plus, a microbial consortium. Pots filled with various wastes (sugarcane, plants, flowers, etc.) were inoculated with the activator and composted over 60 days. Results showed temperatures increased more rapidly in treated waste, reaching up to 58°C on day 20 versus controls. Dry matter content decreased more in treated waste as well, with losses of 37.73-52.94% of initial amounts depending on waste type. The microbial consortium accelerated the composting process, demonstrating its effectiveness for waste treatment.Phytochemical Screening and Antimicrobial Effects of Leaf and Root Extracts o...
Crotalaria brevidens (slenderleaf) leaves and shoots are used as food and have medicinal properties when consumed by human beings. It also acts as an agent in promotion of suicidal germination of striga, a parasitic plant that is a major problem weed for maize and millet growers. In view of its medicinal importance, and there being increased tolerance of many microorganisms towards known antibiotics, there is a need to establish the anti microbial properties of extracts obtained from its roots, stem, leaf and other body parts against pathogenic microorganism. Even though this plant is reported to have immense medicinal value in treating stomach related ailments, malaria and many other tropical diseases, before this study little was known about the antimicrobial potentials of its roots, stem and leaves against three candidate microorganisms namely; Candida albicans, staphylococcus aureus and E. coli. This study was thus initiated to investigate (1) the antimicrobial effects of slenderleaf on Candida albicans, staphylococcus aureus and E. coli, and (2) establish the presence of phenols, steroids, glycosides, saponins, quinones, tannins, terpenoids and flavonoids in its crude leaf and root extracts. The plant roots and leaves used during these studies were collected, shade dried and blended to obtain a fine powder. Ethanol was used as the solvent to extract the pure components by dissolving 25g of leaves and 6g of roots separately in 150ml of ethanol in each case. After seven days, the extract was filtered and the filtrate put in a rotary evaporator to obtain a pure solid sample of the extract. A stock solution was made with 3g of the leaf extract that resulted by dissolving in 40ml distilled water making a concentration of 75mg/ml. the stock was diluted to 3.75mg/ml, 11.25mg/ml, 18.75mg/ml and 37.5mg/ml as 5%, 15%, 25% and 50% respectively. A control with distilled water (0%) was used. This was then replicated thrice to minimize variability and arranged in a completely randomized design. The screening of antimicrobial activity of crude extracts was done by measuring the zone of inhibition using agar diffusion method. Data obtained were subjected to analysis of variance (ANOVA) and means separated and compared using least significance difference (LSD) at (p<0.05). There was a clear zone observed around the discs impregnated in the extract and transferred to the inoculated petri dishes. High inhibition was observed on Escherichia coli at a concentration of 37.5mg/ml. phytochemical screening showed presence of flavonoids, tannins, saponins, anthraquinones, phenols, terpenoids and cardiac glycosides as secondary metabolites. The crude extracts obtained in these studies clearly indicated antimicrobial properties against the three tested microorganisms, and therefore there is need to determine the main active components for studies that may lead to the discovery of new natural drugs.

Phytoremediation
Phytoremediation uses plants to remove, detoxify, or immobilize environmental pollutants like metals and organic compounds from soil and water. It works through natural processes of plants like absorption, accumulation, precipitation, volatilization, and stimulation of degrading microbes. Common mechanisms include phytoextraction, phytostabilization, phytotransformation, phytostimulation, and rhizofiltration. While cost-effective and environmentally friendly, phytoremediation is slow and not suitable for highly contaminated sites. Plant species are chosen based on their ability to uptake and process contaminants as well as adapt to soil and climate conditions.

Introduction - phyto- “plants”remedium -“restoring balance.”What is phytoremediation?
Purpose of the study-find effective and sustainable ways.Strategies involved in process of
phytoremediation.Evaluating the economic feasibility and social acceptability.Goal of phytoremediation.
Overview of phytoremediation
Phytoextraction -Removal and Storage of contaminants in plants.E.g. Sunflower for uranium removal. Mustard for lead removal.
Phytostabilization -Transformation of highly toxic species to less toxic species or reduction in mobility.
Phytodegradation- Uptake and degradation of organic compound by plants. Plants contain – nitroreductase, dehalogenases, lacasses.
Rhizofiltration-Use of roots to uptake also store contaminants from an aqueous growth matrix.
Phytovolatilization- Volatilization of toxic compound into atmosphere. Plants have ability to convert toxic metal ions into volatile species. E.g., Poplar plant- Trichloroethane Eucalyptus- Methyl-t-butyl–ether
Properties of phytoremediation-High tolerance to the pollutants. High biomass production, fast growth.Large, deep root system.Good accumulator/degrader of pollutant. Able to compete with other species. Economic value.
Inorganics-Metals - Pb, Cd, Zn, Cr, Hg .Metalloids- Se, As.Nutrients- K, P, N, S.Radionuclides- Cs, U.
Organics: PAHs.Pesticides.Petroleum.Hydrocarbons.
Examples Of Plants Used In Phytoremediation-Sunflower (Helianthus Annuus ),Willow (Salix species), Poplar tree (Populus deltoides),Indian mustard (Brassica juncea ),Indian grass (Sorghastrum nutans Nash).
Transgenic approaches to Phytoremediation.
Adavantages -Suited to remediation of large areas of soil.Cost effective compared to conventional methods.Easy to implement and maintain and also accepted by public.Fewer spread of contaminants via air and water.Environmental friendly and aesthetically pleasing to public.
Limitations-Can be Slower. Limited root depth.
Plant tolerant to pollutants/contaminants.
Potential phase transfer of contaminant.
Possibility of contaminated plants entering the food chain.Possible spread of contaminant through falling leaves.
Conclusion-Phytoremediation is an emerging technology that employs the use of higher plants for the cleanup of contaminated environments. The main advantage of phytoextraction is environmental friendliness. Traditional methods which are used for cleaning up heavy metal contaminated soil disrupt soil structure and reduce soil productivity, whereas phytoextraction can clean up the soil without causing any kind of harm to soil quality.Another benefit of phytoextraction is that it is less expensive than any other clean up process and the possibility of the recovery and re-use of valuable metals.The possibility of using biotechnology to improve the efficiency of pytoremediation processes makes even better than any other existing methods.

Utilization of Agro-industrial waste and by products.pptx
Agricultural industries produce large amounts of waste each year that can pollute the environment if not properly disposed of. These wastes contain nutrients that can be used in solid state fermentation to produce beneficial compounds. Solid state fermentation uses agricultural waste as a solid substrate for microbial growth without free water. It can be used to increase the antioxidant properties of wastes like pineapple peels and produce antibiotics or tempeh using wastes as substrates. Utilizing agro-industrial wastes through solid state fermentation helps reduce costs, recycles waste, and protects the environment.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Phytoremediation
- 1. Subjective Assignment II of MOOC ON ACADEMIC WRITING (UGC) ACADEMIC WRITING Submitted by PRIYANKA.P (Application No: bd98a885e9cf11e9b6593f9b844f09b7) SASTRA University, Thanjavur.
- 2. Contents Phytoremediation Types of phytoremediation Merits and Demerits of phytoremediation Application of phytoremediation.
- 3. Phytoremediation Phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the soil and ground water. Phytoremediation is a cost-effective plant-based approach of remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues. It refers to the natural ability of certain plants called hyperaccumulators to bioaccumulate, degrade, or render harmless contaminants in soils, water, or air. Toxic heavy metals and organic pollutants are the major targets for phytoremediation.
- 4. Types of phytoremediation Phytoextraction Phytodegradation Phytostabilization Phytovolatilization Rhizodegradation.
- 6. Merits and Demerits Merits : 1. It preserves the topsoil, maintaining the fertility of the soil 2. Increase soil health, yield, and plant phytochemicals 3. the use of plants also reduces erosion and metal leaching in the soil Demerits: 1. Phytoremediation is limited to the surface area and depth occupied by the roots. 2. Slow growth and low biomass require a long-term commitment.
- 7. Applications Phytoremediation may be applied wherever the soil or static water environment has become polluted or is suffering ongoing chronic pollution. Examples where phytoremediation has been used successfully include the restoration of abandoned metal mine workings, and sites where polychlorinated biphenyls have been dumped during manufacture and mitigation of ongoing coal mine discharges reducing the impact of contaminants in soils, water, or air. Contaminants such as metals, pesticides, solvents, explosives, and crude oil and its derivatives, have been mitigated in phytoremediation projects worldwide. Many plants such as mustard plants, alpine pennycress, hemp, and pigweed have proven to be successful at hyperaccumulating contaminants at toxic waste sites.
- 8. Conclusion Phytoremediation is economically low cost method that can be applied for wide range of contaminants in the soil. Plants like marigold, poplar tree, mustard, sunflower etc., are found to have good remediation against the contaminants.
- 9. Feedback for the course It is an extremely beneficial and important course for academicians like us since we are required to write research papers, articles and case studies for professional enhancement. Hence, it is important to have good academic writing skills The entire course content is well planned and designed which enables step by step learning. Plagiarism and Journal and Author Metrics were the two modules I liked the most. I am definitely going to take suggestions from the current ‘Academic Writing Course’ that I’m attending.
