Extensive applications of organochlorine pesticides like endosulfan have led to the contamination of soil and environments. Five different bacteria were isolated from cockroaches living in pesticide contaminated environments. According to morphological, physiological, biochemical properties, and total cellular fatty acid profile by Fatty Acid Methyl Esters (FAMEs), the isolates were identified as Pseudomonas aeruginosa G1, Stenotrophomonas maltophilia G2, Bacillus atrophaeus G3, Citrobacter amolonaticus G4 and Acinetobacter lwoffii G5. This is the first study on the bacterial flora of Blatta orientalis evaluated for the biodegradation of α-endosulfan. After 10 days of incubation, the biodegradation yields obtained from P. aeruginosa G1, S. maltophilia G2, B. atrophaeus G3, C. amolonaticus G4 and A. lwoffii G5 were 88.5% , 85.5%, 64.4%, 56.7% and 80.2%, respectively. As a result, these bacterial strains may be utilized for biodegradation of endosulfan polluted soil and environments.
像硫丹这样的有机氯农药的广泛应用导致了土壤和环境的污染。从生活在农药污染环境中的蟑螂体内分离出了五种不同的细菌。根据形态学、生理学、生化特性以及通过脂肪酸甲酯（FAMEs）分析的总细胞脂肪酸谱，这些分离菌株被鉴定为铜绿假单胞菌G1、嗜麦芽窄食单胞菌G2、萎缩芽孢杆菌G3、无丙二酸柠檬酸杆菌G4和洛菲不动杆菌G5。这是首次对东方蜚蠊的细菌群落进行评估，以研究其对α-硫丹的生物降解作用。经过10天的培养，铜绿假单胞菌G1、嗜麦芽窄食单胞菌G2、萎缩芽孢杆菌G3、无丙二酸柠檬酸杆菌G4和洛菲不动杆菌G5的生物降解率分别为88.5%、85.5%、64.4%、56.7%和80.2%。因此，这些细菌菌株可用于硫丹污染土壤和环境的生物降解。
