Abstract

Several bacteria species may have the ability to degrade and digest soundly the residuals of certain insecticidewith causing any deteriorated consequences. This work was designed to examine the ability of Aeromonashydrophila bacteria for biodegrading of chlorpyrifos insecticide from contaminated soil. However, soilsample was collected from home garden at depth of 10 cm while the chlorpyrifos insecticide was obtainedfrom the local market. Meanwhile Aeromonas hydrophila bacteria were isolated from the garden soil. Thebacterial cultural media were prepared to consist of (NH4)2SO4 (1g), NaCl (6g ), K2HPO4 (0.5g), yeastextract (1g ), MgSO4 (0.1g) and CMC (5g). This work has examined the efficiency of A. hydrophila bacteriato remove insecticide from the soil under various growing conditions such as five different pH values,five termperature degrees and four insecticide concentrations. The obtained results showed that the highestbacterial efficiency (98.0 ± 7.8%) was recorded as pH value of 6 and it was 91.1 ± 6.0% at temperature of40 ° C while it was 99.1 ± 6.8 % at insecticide concentration of 25 ppm.
