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.
