This waste water without any treatment if released directly to water bodies or soil causes pollution of water and soils. Various agroindustry by-products viz., sawdust, corn cob, wheat husk, bagasse, rice bran, etc. are generated in huge amount which are disposed directly to the landfills or incinerated which causes pollution. The agroindustry by-products can be used to prepare biochar. In this work, wheat husk was used to prepare biochar. This wheat husk based biochar was used for the study of removal of pathogens from waste water. The biochar was also used to check if it can be used for treatment of water by study of total suspended and dissolved solids. The reduction of pathogens in waste water samples A and B using wheat husk based biochar observed was 90 and 80% respectively when compared to untreated waste water samples. Also, no colonies of E. coli were observed after treating the waste water samples A and B with wheat husk based biochar. The reduction in total suspended and dissolved solids observed was 97.7 and 76.3% respectively when compared to the untreated water sample. Wheat husk based biochar can be used for the removal of pathogens such as E. coli from waste water. The biochar can also be sued for the treatment of waste water. The use of biochar for the removal of pathogens, solids and other pollutants from waste water will be very cheap and eco-friendly.","PeriodicalId":254148,"journal":{"name":"Micro Environer","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115881362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, different strategies are needed to maintain and revive the crop resources required for agriculture. Pesticides in soil solution can either be adsorbed by soil colloids or degraded by microorganisms. The use of pesticides against diseases and pests that reduce the yield of plants continues to increase day by day. However, it also threatens the life of living things. Over time, many insects and weeds resistant to pesticides have emerged, and it has been seen that the dose of pesticides should be increased. This situation harms both the environment and the economy. Pesticides stay in the soil for many years, preventing microorganism activities and causing oxidative stress induction. Besides, it is known that pesticides inhibit enzyme activities by participating in some enzymatic events. In this review, we discussed the antioxidant defense mechanisms that develop in microorganisms due to the effect of pesticides on microorganisms and provide biodegradation. When exposed to pesticide toxicity in microorganisms that provide biodegradation, specific biological systems characterized by enzymatic reactions become active. In cases where the enzyme defense of microorganisms is insufficient, biotransformation is carried out by artificially supplementing the environment with enzymes; It contains a series of enzyme-catalyzed reactions, and in this way, the negative factors that the plant is exposed to can be eliminated or mitigated. Microbial enzymes provide biodegradation. In addition, to prevent the biodegradation effect; It is essential to examine this subject to improve the understanding and practical use of enzyme use, enzyme extraction methods and future enzyme-assisted bioremediation processes for their development and evaluation.","PeriodicalId":254148,"journal":{"name":"Micro Environer","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128640560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

T. polium and C. colocynthis were collected from the Sistan region of Iran. Extraction was performed with ethyl acetate, methanol, acetone, and ethanol solvents using a rotary apparatus. E. coli strains were isolated from urinary infections. The minimum inhibitory concentration and the Minimum Bactericidal Concentration were prepared by dilution method in the well. The lowest inhibitory concentration of C. colocynthis ethyl acetate extract was equal to 3.1 ppm, in which 2 strains were inhibited. In comparison, the highest inhibitory concentration was 100 ppm, in which one strain was inhibited in this concentration. The lowest inhibitory concentration of T. polium ethyl acetate extract of E. coli was 3.1 ppm, with 2 strains inhibited. In comparison, the highest inhibitory concentration was 50 ppm, with one strain at this concentration. This study showed that the lower inhibitory concentration of C. colocynthis ethyl acetate extract against C. albicans was 25 ppm. The lowest inhibitory concentration of T.polium methanol extract against C. albicans was 12.5 ppm, which was unilaterally inhibited in this concentration.
