ABSTRACT

Pyrethroid group of pesticide is widely used in agriculture area to control pest. Bifenthrin [2-methylbiphenyl- 3-ylmethyl-(Z)- (1RS)-3- (2-chloro-3,3,3-trifluoroprop-1-enyl) -2,2 dimethylcyclopropane carboxylate] is one type of pyrethroide pesticide group, which is used for control of broad spectrum of insect pest of economically important crops and considered as dangerous toxic component. The present work deals with the biodegradation of bifenthrin by using indigenous bacteria isolated from contaminated soil. It describes the biodegradation of bifenthrin by bacterial isolate IY1 which degrades bifenthrin into non toxic metabolites like benzene 1, 1(methylthio) ethylidine, monochlorotrifluromethane and benzene which was confirmed by FTIR and GCMS analysis.

Keywords: Biodegradation, Pesticide, Bifenthrin, FTIR, GCMS.
