Using the various bio chemical indicators, the efficiency of chlropyrifas ethyl remediation by methyloacterium radiotoleras and micro bacterium arthrosphaeral was assessed

Abstract

This study examines the detoxifying and antioxidant enzyme responses of Gammarus pulex before and after biodegradation/bioremediation by Methylobacterium radiotolerans and Microbacterium arthrosphaerae after exposure to chlorpyrifos-ethyl pesticide.G. pulex treated to chlorpyrifos-ethyl had its cytochrome, glutathione S-transferase, catalase, and superoxide dismutase activities measured using commercial ELISA kits before and after bioremediation/biodegradation by these two bacteria for 24 and 96 hours.Before and after bioremediation/biodegradation, the activity of the catalase enzyme was reduced based on chlorpyrifos-ethyl, and then elevated again.After 4 days of exposure to chlorpyrifos-ethyl, superoxide dismutase activity increased.
