The ability
of five bacterial isolates (Pseudomonas aeruginosa,
Klebsiella Sp., Escherichia coli, Bacillus
Sp. and Corynebacterium) isolated from Brinjal
cultivated field to degrade cypermethrin was studied. It was
confirmed that these isolated organisms were able to utilize
and degrade cypermethrin. In this five different bacterial
colonies, P. aeruginosa, Klebsiella Sp., E.
coli were found active in utilizing cypermethrin (1%)
where as Bacillus Sp. and Corynebacterium were
moderately active in utilizing cypermethrin (0.1%). The
growth curve experiment was performed at 0.1 and 1% dose of
cypermethrin to analyze the viable count of P. aeruginosa.
