Abstract

Quinoline, a nitrogenous heterocyclic compound (NHC), is a common pollutant in many fossil industrieswastewaters, such as coking plant wastewater. Due to the limitation of knowledge for the diversity of quinoline degrading bacteria, the isolation of diverse degrading bacteria from quinoline contaminated environment is important work not only for understanding the process of quinoline degradation, but also for optimizing the wastewater treatment. In this study, 56 strains of quinoline degrading bacteria were isolated from quinoline acclimated bioreactor and coking wastewater treatment bioreactor under different culture conditions. These strains were grouped into 12 OTUs by ADRDA and the representative sequences of these OTUs were affiliated to Ochrobactrum, Bacillus, Pseudomonas and Rhodococcus. Some of these strains were used for measuring their quinoline degrading capabilities. Most of the assayed strains showed high degrading efficiency, except that a few strains could not degrade quinoline independently. As we know, it is the first report that the bacteria of Ochrobactrum could degrade quinoline so far. Fig 2, Tab 3, Ref 31.
