Biodegradation of α-endosulfan via hydrolysis pathway by Stenotrophomonas maltophilia OG2.

ABSTRACT: Stenotrophomonas maltophilia OG2 was isolated from the intestine of cockroaches that was collected from a cow barn contaminated some pesticides belong to pyrethroid and organochlorine groups. OG2 was able to degrade α-endosulfan in non sulfur medium (NSM) as a sole sulfur source for growth within 10 days of incubation. The effects of some growth parameters on endosulfan biodegradation by OG2 was studied and found that the biodegradation was significantly affected by the endosulfan concentrations, pH and temperature. Experimental results obtained in different conditions show that the optimum concentration of α-endosulfan, pH and temperature were 100 mg/L, 8.0 and 30 °C, respectively. Under these conditions, the bacterium degraded 81.53% of the α-endosulfan after 10 days. The concentration o
