Özet

Extensive use of pesticides has led to the contamination of ecosystem. Therefore, it is important to isolate potential new pesticide-degrading bacteria. For the biodegradation of alpha-endosulfan and alpha-cypermethrin, a new bacterium was isolated from the body microflora of grasshopper (Poecilimon tauricola). Based on biochemical, morphological, and 16S rRNA sequence analysis, the isolated strain B7 was identified as Acinetobacter schindleri. This bacterial strain was screened for its alpha-cypermethrin and alpha-endosulfan degrading potential with minimal salt medium (MSM) and non-sulfur medium (NSM), respectively. When glucose was added to non-sulfur medium containing alpha-endosulfan (100 mg/L) and minimal salt medium containing alpha-cypermethrin (100 mg/L), both pesticide degradation and bacterial growth were increased. Acinetobacter schindleri B7 was able to degrade 67.31% of alpha-endosulfan and 68.4% of alpha-cypermethrin within 10 days. The degradation products of pesticides were determined by HPLC. As a result, A. schindleri, a Gram-negative bacterium, can inevitably be used in the biological treatment of environments exposed to pesticides.
