Comparison the Biodegradation Efficiency of Cypermethrin by Pseudomonas aeruginosa and Enterobactercloacae

Mustafa Hamza AlMamoory, Ithar Kamil Al-Mayaly

Abstract: Two local bacterial isolates were isolated from agriculture soil contaminated with cypermethrin from AlAbaeje village in Baghdad city, Iraq. Primary screening was done to test bacterial ability to growth and resistance to cypermethrin by using nutrient agar plates containing 500 mg L-1 cypermethrin as a sole source of carbon and energy, and incubation at 37 for 72 hours. Secondary screening results showed that these two bacterial isolates have the ability to grow and resistance cypermethrin concentration till 3600 mg L-1 in solid MMSM. In lab experiment and under optimal conditions, cypermethrin biodegradation was measured by using FTIR and GC-MS analysis. The results shown that E.cloacae was the best isolate for degrading cypermethrin with percentage 94 % while P. aeruginosa with degrading percentage 88 %.
