Abstract

Isolation, characterization and screening of Cypermethrin-Degrading bacteria from agricultural soil Cypermethrin is a common pesticide that have been widely used since 1980's. Its toxicity toward aquatic organisms and humans requires its complete removal from contaminated areas which can done through bioremediation. The aims of this study were to isolate, characterize and screening the potential cypermethrin-degrading bacteria from the agricultural soil. The isolation technique was done through direct plating and about 10 strains were successfully isolated. They were identified as Sphingomonas paucimobilir NADPL-(R1, Pseudomonas oryzihabitan!rNADPL-(R2, Staphylococcus aureus-NADPL-CR3,Staphylococcus aureus-NADPL-CR4, Pasteurella pneumotropica-NADPL -CRS, Pseudomonas luteola-NADPL-CR6, Pseudomonas aeruginosa-NADPL-CR7, Pseudomonas oryzihabitans-NADPH-CR8, Haemophilus influenza-NADPH-CR9 and Stenotrophomonas maltopht1Ia-NADPH-CR10. However, only Staphylococcus aureus and Pseudomonas aeruginosa were able to utilize cypermethrin as their carbon source. The growth of these two strains were tested at different initial cypermethrin concentration and pH in order todetermine their optimum condition based on these two variables. Staphylococcus aureus had been recorded to grow better and higher in the presence of cypermethrin than Pseudomonas aeruginosa.
