Three distinct agricultural waste materials, viz., casuarina fruit powder (CFP), sorghum stem powder
(SSP), and banana stem powder (BSP) were used as low-cost adsorbents for the removal of toxic lead(II)
from aqueous solutions. Acid treated adsorbents were characterized by scanning electron microscopy (SEM),
energy-dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR). The
effects of parameters like adsorbent dose, pH, temperature, initial metal ion concentration, and time of
adsorption on the removal of Pb(II) were analyzed for each adsorbent individually and the efficiency order
was BSP > SSP > CFP. Based on the extent of compatibility to Freundlich/Langmuir/Dubinin–Radushkevich/
Temkin adsorption isotherms and different models (pseudo-first and second order, Boyd, Weber’s, and
Elovich), chemisorption primarily involved in the case of BSP and SSP, whereas simultaneous occurrence of
chemisorption and physisorption was proposed in the case of CFP correlating with the thermodynamic study
results conducted at different temperatures. Based on the observations, it was proposed that three kinetic
stages involve in the adsorption process, viz., diffusion of sorbate to sorbent, intra particle diffusion, and then
establishment of equilibrium. These adsorbents have a promising role towards the removal of Pb(II) from
industrial wastewater to contribute environmental protection

Abstract
Water is the elixir of life, a precious gift of nature to all the living species on earth. It is rapidly becoming a scare commodity in most parts of the world. Only 0.35% of the total availability of water found in lakes and wetlands and 0.01% in rivers and streams which are likely getting depleted due to the discharge of the effluents such as dyes simultaneously increases the water quality parameters. Malachite green is a common textile dye being discharged in lake water situated near textile industries. The phycoremediation method employs the use of algae, say, Chlorella pyrenoidosa which helps in decolorizing the water and due to its growth in the lake water, the physico-chemical parameters higher in the polluted water found to be reduced and water can be used for various purposes. The trails were made using Chlorella pyrenoidosa and Malachite green at different concentrations. The optimum concentration for the degradation of dye was completely done at the concentration 15 mg confirming the decolorization capacity by Chlorella pyrenoidosa. The same experiment was performed with adjusting the pH at 6, 7 and 8. Optimum pH for the dye degradation was found as pH 7 at which all the concentrations Chlorella pyrenoidosa was able to degrade the dye with the decolourization capacity of above 95%. The phyico-chemical parameters checked after the decolorization by Chlorella were found to be within the limits and thus Chlorella which is available in nature can be used in the decolorization of effluent water by eco-friendly method.

A combined hydrolysis process, which first mixed dilute acid- and alkali-pretreated corn stover at a 1:1 (w/w) ratio, directly followed by enzymatic saccharification without pH adjustment, has been developed in this study in order to minimize the need of neutralization, detoxification, and washing during the process of lignocellulosic biofuel production. The oleaginous fungus Mortierella isabellina was selected and applied to the combined hydrolysate as well as a synthetic medium to compare fungal lipid accumulation and biodiesel production in both shake flask and 7.5 L fermentor. Fungal cultivation on combined hydrolysate exhibited comparable cell mass and lipid yield with those from synthetic medium, indicating that the integration of combined hydrolysis with oleaginous fungal lipid fermentation has great potential to improve performance of advanced lignocellulosic biofuel production

CULTIVATION OF OSCILLATORIA SP IN DAIRY WASTE WATER IN TWO STAGE PHOTO BIOREA...civej
This paper presents an integrated approach to cultivate microalgae in dairy wastewater and to
investigate the capability of the organism for biodiesel production. The present study was carried out
using tolerant strains of microalgae collected from dairy effluent treatment plant, Kochi. Selected blue
green algal strains were mass cultured in the laboratory and acclimatized using different concentrations
of synthetic effluent. Blue green algal filaments were immobilized inside the primary and secondary
photobioreactors. The experiment was conducted in two stages including batch and continuous
treatment. The stage 1 of the experiment was designed for the reduction of physical impurities and the
nutrients. Stage 2 was designed mainly for the cultivation of blue green algae in dairy waste water by
utilizing the extra nutrients . Reduction of 94 -99.5% in phosphate was observed after 48 h of treatment
in the primary and secondary photobioreactors. The level of phosphate, total hardness, ammoniacal
nitrogen in the MSE was reduced by 97%,93 %, 81% respectively. BOD was reduced to 370mg L-1 from
1500 mg L-1 after 48 hrs of treatment in the primary reactor. COD was reduced to 85 mg L -1 from an
initial value of 1500 mg L -1 from medium strength effluent (MSE) and 90-95 % removal of COD was
also obtained from high strength effluent(HSE) during the study period. Biomass developed within the
reactor was harvested at every 15 days intervals from the secondary reactor and analyzed for lipids and
fattyacids. Presence of C14:0, C16:0,C18:0, C18:1 and C18:2 fatty acids strongly supports its abilility for
biodiesel production.

Microbial Decolorization of Leather Dye Effluentijtsrd
As we know 71% of Earths Surface is covered with water. Water is one of the most essential element for the persistence of life on this planet. Pure and contamination free water is the dire necessity of every living being present on Earth but today water pollution has posed great threat to the existence of life. The discharge of effluents from various industries into the water bodies are mainly responsible for water pollution specially effluents from leather industry are the most contaminating as along with the harmful chemicals they contain organic matter as well. The dyes disposed by the leather industry are the most harmful for the environment. The conventional physicochemical methods used for the treatment of leather dyes in the contaminated water i.e. coagulation, precipitation, oxidation etc have disadvantages and limitations. This study presents microbial decolorization of leather dye effluents from Shigella sp. isolated from effluent samples collected from leather industry. Different parameters such as temperature and pH were optimized for decolorization of Methylene Blue, Crystal Violet, EosinYellow, Safranine dyes by using bacterial isolates. Optimum temperature for decolorization was observed to be 300c, the optimum pH range for decolorization was found to be from pH6-pH8. All the samples were incubated at 30-°C 150 rpm. The decolorization was measured as decrease in absorbance maxima at 663 nm, 590 nm, 518nm, 530 nm for mehtylene blue, crystal violet, eosin yellow, safranine respectively.

Biosystem treatment approach for seaweed processing wastewater Premier Publishers
Wastewater obtained from the seaweed washing process often contains residual chemicals, as the seaweed is typically washed using chemicals. Here, we used a biosystem to treat wastewater obtained after seaweed processing. The research goals were to determine the effectivity and capacity of this biosystem for reducing chemical oxygen demand (COD), biological oxygen demand (BOD), and nitrites in the wastewater. We planted and prepared the biosystem bin, adapted the plants in the biosystem bin until they were ready for use, and we performed wastewater treatment using the biosystem either with or without the addition of an active bacterial suspension. The results show that addition of the active suspension significantly improved effectivity with respect to COD and nitrites (p<0.05). With respect to COD, BOD, and nitrites, the effectivity of the biosystem with an added active suspension was 83.9, 87.2, and 55.5%, respectively; the effectivity of the biosystem without the active suspension was 79.2, 83.3, and 38.7%, respectively. The capacity of the biosystem with an added active suspension was 13.226, 6.805, and 0.014mg/L/m3hour with respect to reducing COD, BOD, and nitrites, respectively; the capacity of the biosystem without an active suspension was 12.485, 6.496, and 0.009 mg/L/m3hour, respectively.
Isolation, Screening, and Characterization of Biosurfactant-Producing Microor...BRNSS Publication Hub
Introduction: Biosurfactants are amphiphatic in nature and are surface-active compounds produced by microorganisms. These molecules reduce interfacial surface tension between aqueous solutions and hydrocarbon mixtures. Unfortunately, oil spills and industrial discharges from petroleum-related industries have been identified as the major pollution sources. The hydrophobicity and low aqueous solubility of petroleum pollutant limit the biodegradation process. The features that make biosurfactants as an alternative to commercially synthesized surfactants are its low toxicity, higher biodegradability and, hence, greater environmental compatibility, better foaming properties, and stable activity at extreme pH, temperature, and salinity. Objective: Therefore, in this study, hydrocarbon-degrading bacteria were screened from petroleum-contaminated soil, characterized and optimization of the physical and nutrient parameters were done to enhance the production of biosurfactants. Results: Petroleum-contaminated soil was collected from different petrol pumps in Pune and screening was done on minimal salt medium media containing palm oil as carbon source using hemolytic activity, emulsification index, drop-collapse test, and oil displacement method. The most promising strain was isolated and identified using Bergey’s Manual of Determinative Biology and 16s rRNA sequencing and was found to be Staphylococcus epidermidis. The optimization of various parameters, namely temperature, pH, carbon, and nitrogen sources on growth, and biosurfactant production was studied. The highest biosurfactant production was obtained when MSS media contains sucrose (carbon source) and urea (nitrogen source) at pH 10 and temperature 55°C. The Fourier transform-infrared (FT-IR) analysis of purified biosurfactant indicated the presence of lipopeptide biosurfactant when compared with reference FT-IR spectra.
Production of Spirulina in semicontinuous cultivation using medium recycleIJERA Editor
The biomass of cyanobacteria Spirulina is rich in bioactive compounds, with main applications in food and pharmaceutical industry. The objective of this study was to evaluate the effect of nutrient consumption on the growth kinetics of Spirulina sp. LEB 18 grown in semicontinuous cultivation in raceway bioreactor. Zarrouk medium was used, maintaining the original concentrations of carbon, nitrogen and phosphorus, while the other nutrients varied by 25%, 50%, 75%, and 100%. Chemical determinations were performed in the biomass for each growth cycle. Spirulina sp. LEB 18 exhibited cell growth until approximately 130 days of experiment. The maximum specific growth rate (0.184 d-1) and productivity (48.03 mg L-1 d-1) were observed in the trial with 50% Zarrouk medium, except for nitrogen, phosphorus and carbon. Nitrogen and phosphorus concentrations reduced up to 100% and 64.8%, respectively. No significant difference (p <0.0003) was observed in the protein concentrations for all tests. The results showed that Spirulina sp. LEB 18 can provide high growth rate and productivity, as well as production of proteic biomass when cultivated with lower nutrients concentration in Zarrouk medium, thus reducing production costs.

Phycoremediation is a green technology that supports the direct use of living green microalgae for in situ, or in place removal, degradation, of contaminants in soils, sludge, sediments, surface water and ground waters by the mechanisms of bio-transformation, bio-accumulation, bio-concentration, bio-sparging.
It can be said by the current study that microalgae has a great potential for the treatment of industrial and municipal wastewaters as compared to the chemical treatments available commercially. Biological systems are much more efficient in cleaning the excess nutrients from the waste water followed by generation of valuable biomass which can be applied in the food, fertilizer, energy production as use of inorganic chemicals like lime and ferrous sulphate generates huge amount of sludge in textile industries, but on the other hand static anaerobic treatment using acclimatized MLSS gives better colour reduction with zero sludge generation. Microalgal cells can be used in free form to treat waste waters containing high C.O.D., high ammonical nitrogen and high TDS. It not only provides a better reduction of chemicals from wastewaters but it also helps to reduce the operational cost of ETP. Microalgaes not only helps to remediate industrial waste waters but also to treat sweage water and to restore natural water bodies like lakes and ponds. As they are active in remediating the chemicals but also it shows an antagonistic effect against some pathogenic germs like total coliforms and fecal coliforms.
These microalgal cells can also be combined with bacterial biomass of activated sludge process to develop an Algal-Bacterial consortium (ALBA) for better enhancement in the reduction of chemicals from the wastewaters as this symbiotic relation of algae and bacteria provides high satiability of the microalgae along with MLSS and faceable in terms of price and economy for instance the bacterial biomass provides carbon dioxide to algal cells for photosynthesis and in return the bacteria acquires oxygen from algae. The harvested biomass from the ETP’s can be used as bio-fertilizers as it consists of appropriate ratio of vital macro and micro nutrients like N,P,K etc. which enhance the growth of plantlets. It can also be used as aqua feeds for shrimps, fishes and molluscs. Furthermore these microlgal cells are non-toxic in the environment as it becomes a part of food chain and do not cause eutrophication. Therefore, micro-algal based treatment is most suitable for the treating the waste waters and restoring the natural water bodies as compared to other chemical treatments.
Optimization and Production of Itaconic Acid from Estuarine Aspergillus terre...BRNSS Publication Hub
Itaconic acid (IA) is an organic acid. It is used in medicine, resins, agriculture, and polymer production. In the present study, sediment sample was collected aseptically from Vellar estuary, Parangipettai, Tamil Nadu, India. About 1.6 × 102 to 6.1 × 103 colony forming units/g density of fungal strains were isolated and screened for IA production. As a result of the tested strains Aspergillus terreus was observed as the most potential strain. Optimization was done at different temperatures (25–45°C), in different pH (5.0–7.0). The impact of salinity on IA production was evaluated using various salinity (5–25 ppt), carbon sources (1% w/v of glucose, sucrose, dextrose, and maltose), nitrogen sources (0.5% sodium nitrate, ammonium nitrate, and potassium nitrate), and cheaper sources (1% w/v molasses, jackfruit waste, wheat bran, and coconut oil cake). As a result optimized culture condition for IA production was 1% w/v of glucose - best carbon source, 1% w/v molasses - best cheaper carbon source, 0.5% of sodium nitrate - best nitrogen source, salinity - 20 ppt, temperature - 40°C, and pH - 5.5 and incubation time – 96 h. Compared to glucose (0.41 mg/ml) production of IA was high when molasses (0.61 mg/ml) was used as carbon source, it is also economically good. Mass scale culture was done using molasses instead of glucose with an optimized parameter. After mass scale culture, IA production was 6.3g/l.

These microalgal cells can also be combined with bacterial biomass of activated sludge process to develop an Algal-Bacterial consortium (ALBA) for better enhancement in the reduction of chemicals from the wastewaters as this symbiotic relation of algae and bacteria provides high satiability of the microalgae along with MLSS and faceable in terms of price and economy for instance the bacterial biomass provides carbon dioxide to algal cells for photosynthesis and in return the bacteria acquires oxygen from algae. The harvested biomass from the ETP’s can be used as bio-fertilizers as it consists of appropriate ratio of vital macro and micro nutrients like N,P,K etc. which enhance the growth of plantlets. It can also be used as aqua feeds for shrimps, fishes and molluscs. Furthermore these microlgal cells are non-toxic in the environment as it becomes a part of food chain and do not cause eutrophication. Therefore, micro-algal based treatment is most suitable for the treating the waste waters and restoring the natural water bodies as compared to other chemical treatments.
Optimization and Production of Itaconic Acid from Estuarine Aspergillus terre...BRNSS Publication Hub
Itaconic acid (IA) is an organic acid. It is used in medicine, resins, agriculture, and polymer production. In the present study, sediment sample was collected aseptically from Vellar estuary, Parangipettai, Tamil Nadu, India. About 1.6 × 102 to 6.1 × 103 colony forming units/g density of fungal strains were isolated and screened for IA production. As a result of the tested strains Aspergillus terreus was observed as the most potential strain. Optimization was done at different temperatures (25–45°C), in different pH (5.0–7.0). The impact of salinity on IA production was evaluated using various salinity (5–25 ppt), carbon sources (1% w/v of glucose, sucrose, dextrose, and maltose), nitrogen sources (0.5% sodium nitrate, ammonium nitrate, and potassium nitrate), and cheaper sources (1% w/v molasses, jackfruit waste, wheat bran, and coconut oil cake). As a result optimized culture condition for IA production was 1% w/v of glucose - best carbon source, 1% w/v molasses - best cheaper carbon source, 0.5% of sodium nitrate - best nitrogen source, salinity - 20 ppt, temperature - 40°C, and pH - 5.5 and incubation time – 96 h. Compared to glucose (0.41 mg/ml) production of IA was high when molasses (0.61 mg/ml) was used as carbon source, it is also economically good. Mass scale culture was done using molasses instead of glucose with an optimized parameter. After mass scale culture, IA production was 6.3g/l.
Isolation and screening of haloalkaline protease producing bacteria from tann...eSAT Journals
Abstract
Twenty bacterial strains were isolated on selective milk agar plates (pH 9.0) from tannery solid waste on the basis of different
colony morphology. These strains exhibited variable haloalkaline protease activity and were tolerant to different concentration of
both chromate (350-1450 μg/ml) and NaCl (2-9%). Those having clearance zone greater than 20.0 mm were considered as
significant isolate. Out of twenty, nine strains were interestingly tolerant to high concentration of Cr(VI) (850-1450 mg/l) and
NaCl (6.5-9%) and exhibited vibrant clear zone diameter between 21-35 mm. All these isolates in this study were capable of
reducing Cr(VI) aerobically and the reduction values ranged between 50.0-76.0% after 16-20 h of growth. Further, significant
haloalkaline protease production was observed in these bacteria within 24 h under wide temperature (25-45°C) and pH (8.0-10.5)
range. The potential of these strains to produce protease at higher rate in the presence of wheat bran as a cheap carbon source
and yeast extract or beef extract as a nitrogen source makes them a potential candidate for industrial applications and removal of
Cr(VI) and proteinaceous waste simultaneously from industrial waste of alkaline nature.

A preliminary study on the toxic potentials of shea butter effluent using Cla...IOSR Journals
This study was conducted purposely to evaluate the effects of shea butter effluent (SBE) on the
freshwater inhabitant using Clarias gariepinus as a biological model. A prominent Local factory of shea butter
at Tede, ATISBO Local Government was chosen because the effluent flows directly into a near-by stream that
ends up at a popular Dam in the Local Government on which more than 120,000 people depend for domestic
use.Static bioassay was conducted to determine the LC50 of shea butter effluent to Clarias gariepinus. Ten fishes
each were exposed to 0.05, 0.06, 0.07, 0.08, and 0.09ppt (lethal concentration) of SBE in separate water plastic
bowl of (40cmX29cmX28cm) of 60litres capacity.The lethal Concentration (LC50) value of SBE was 0.057ppt for
96hrs of exposure. Total mortality occurred in the concentrations of 0.08 and 0.09ppt within 24hours of
exposure period. Behavioural reactions exhibited by the fish include erratic movement, air gulping, loss of
reflex, molting, barbell deformation, hemorrhage, and excessive mucus secretion in fish exposed to higher
concentration of shea butter effluent.
The appreciable increase in the mean value of heavy metal, such as Manganese, Nickel, Cadmium,
Zinc, Copper and Lead revealed that the increase in the concentration of shea butter effluent leads to
bioaccumulation of the aforementioned heavy metals in the test organisms. The values for all the metals exceed
the permissible Criteria of the national and international regulatory body. Therefore, Shea butter effluent is
highly toxic to freshwater fishes, its discharged directly into water bodies, new fish farms or in areas close to
aquatic environment should not be encouraged.

Use of liquid rice starch as a source of carbon for growth of Spirulina plate...AbdullaAlAsif1
A study was conducted to examine the culture and growth performance of S. platensis in three different concentrations (25%, 50% and 100%) of digested liquid rice starch media (DLRSM) with 0.2 g/L urea and Kosaric medium (KM) as control for a period of three months from March to May 2018. Each experiment was done in triplicates for a period of 14 days. The growth rate of S. platensis was found to vary with different concentrations of the medium. The cell weight of S. platensis was attained to highest 12.42 mg/L (dry weight) in KM followed by 11.26 mg/L, 8.35 mg/L and 9.11 mg/L in 25%, 50% and 100% of DLRSM, respectively on the 10 th day of culture period. Similar trend also observed in case of chlorophyll a content of S. platensis. The proximate composition of rice starch was analyzed. The percentage of moisture, protein, lipid, ash, crude fiber and nitrogen free extract (NFE) were95.1, 0.2616, 0.1055, 0.1097, 0.1468 and 3.9669, respectively on the basis of moisture (%) and 4.59, 5.70, 2.30, 2.39, 3.20 and 86.41, respectively on the basis of dry matter (%). The results on the growth performance showed that the growth of S. platensis was significantly (P<0.01) higher when grown in 25% concentration of DLRSM than other concentrations in 50% and 100% of DLRSM. The physico-chemical parameters viz. light intensity (2685 to 2773 lux/m 2 /s), temperature (29.6 to 31.5°C), pH (8.3 to 9.9), alkalinity (1150 to 3032 mg/L), Nitrate-N (1.32 to 6.30 mg/L) and phosphate-P (9.75 to 61.50 mg/L) were within optimum level during the culture period.
Tea (Camellia sinensis) Waste for the reduction of Malathion and Phorate in ...Agriculture Journal IJOEAR
Abstract— Diminution of Malathion and Phorate from aqueous solutions by tea waste biomass was examined in a batch experimental setup. Waste tea powder, obtained from University canteen, S.V. University, Tirupati, India has been used as an effective material for the reduction of Malathion and Phorate from aqueous solutions. Characterization of the adsorbent was studied using SEM micrograph and Fourier Transform Infrared spectral analysis. From the FTIR spectrum it is observed that the change in peak position at 3390 cm−1 in the spectrum of the Phorate and Malathion loaded tea powder indicates the binding of these pesticides with hydroxyl groups. The working solutions of the pesticides are in the range of 0.1µg – 1.0µg for Malathion and 0.05µg – 0.5µg for phorate. It was observed that percentage adsorption increased with pH of the liquid phase and reached an optimum value of 95 % for Malathion and 94 % for phorate at pH 7.4 ± 0.2 and pH 7.5 ± 0.2, respectively. The dosage of the adsorbent had showed considerable effect on the adsorption of Malathion and Phorate.

In the present study we monitor the eff ect of copper-contaminated culture media on development and active compound biosynthesis of two Rhodotorula mucilaginosa strains, assigned as R1 and R2. The media was prepared in aqueous extracts of Asclepias syriaca stems and diff erent copper ions concentrations were added. The data reveals that the presence of 10 mg/ L Cu2+ for the Rhodotorula mucilaginosa strain-1 (R1) and 50 mg/ L Cu2+ for the Rhodotorula mucilaginosa strain-2 (R2) strain fermentation increases the biomass yield (24.7 g and 14.8 g wet biomass/ L culture medium, respectively) and biosynthesis of carotenoid pigments (approximately 1.4 μg/ g dry biomass) compared with references. The chelating properties of polyphenol compounds from aqueous extracts of Asclepias syriaca
stems was confi rmed by detection of 17.9 mg/ L Cu2+ in extracts with 100 mg/ L Cu2+ added, after 24 hours at 4°
C. In the residual culture media, we have determines that the Cu2+ concentrations decreased at 14.0 mg/L for Rhodotorula mucilaginosa strain-1 (R1) and 13.8 mg/
L for Rhodotorula mucilaginosa strain-2 (R2) strain fermentation, respectively, which means that the copper was trapped by the yeasts cells. Likewise, the polyphenols are digested and used as a carbon source. These results bring a significant contribution to the possibility of yeast fermentations in a low cost-vegetal polyphenol and copper ions system.
The potential of microalgae meals in compound feeds for aquacultureInternational Aquafeed
Intensive production of mainly carnivorous fish has resulted in fish feeds containing high levels of fishmeal and fish oil, with Europe requiring around 1.9 million tonnes a year. Although this use of fishmeal was initially the recycling of waste from fishing through the use of bycatch and trimmings, due to the rapid development of aquaculture this reliance on fishmeal and fish oil is environmentally unsustainable. This has resulted in other sources of fish feed being investigated. This literature review will focus on microalgae; the composition in terms of nutritional quality, the current methods of production and associated costs along with potential future uses such as feed in aquaculture.

Investigating the bacterial inactivation potential of purified okra (Hibiscus...AZOJETE UNIMAID
The ability of purified okra protein (POP) as coagulant and as disinfectant material in comparison with aluminium sulphate (AS) in water treatment was assessed. A laboratory jar test experiments and Colilert-18/Quanti-Tray method of bacterial analysis were conducted using POP as coagulant in treating river water. The results show an excellent dual performance function of POP against the conventional coagulant, AS in drinking water treatment. It was observed that a marked inactivation of approximately 100% of faecal and E-coli count in raw water was achieved with POP and zero regrowth of bacteria after 72-hour post treatment. However, there was regrowth in total coliform count as a result of the presence of other microbes other than E-coli and faecal coliform in the system. In all cases AS showed a reduced performance against the two indicator organisms achieving only 93% with remarkable regrowth of E-coli and faecal coliform after prolonged storage time in the clarified water. Turbidity removal was also noted to be approximately similar, 92% across all coagulants tested. Therefore, the use of POP in water treatment could improve access to clean water in developing countries and could help in reducing the import of water treatment chemicals.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
