[Isolation, identification, and biodegradation characteristics of a quinoline-degrading bacterium].

A bacterial strain BW003, which could utilize quinoline as sole carbon, nitrogen and energy source, was isolated from the activated sludge in a coking wastewater treatment plant. According to the 16S rRNA gene sequence analysis, the strain was identified as Pseudomonas sp. Biodegradation experiments showed that the strain could degrade 192-911 mg/L of quinoline efficiently within 3-8 h, and the removal rates of quinoline were ranged from 96% to 98%.
