Abstract

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.

Key words: Cypermethrin, bacteria, utilization, growth kinetics, degradation, Pseudomonas aeruginosa.
