采用纯培养技术，对分离自喹啉降解生物反应器的26株优势菌株进行了分析。测定了这些菌株的反硝化能力和好氧降解喹啉的能力。测定了筛选出的菌株对喹啉的降解能力。结果表明，分离到的10株细菌均为细菌，分别属于芽孢杆菌属、葡萄球菌属、假单胞菌属、布鲁氏菌属和代尔夫特氏菌属。而红球菌属的9株菌株在好氧条件下具有降解喹啉的能力。研究了喹啉降解生物反应器中微生物群落中主要优势菌的代谢功能。缺氧生物反应器中存在着多种代谢类型的微生物。
Using the pure culture technology, we analyzed 26 predominant bacterial strains isolated from a denitrifying quinoline-degrading bioreactor. The capacity of denitrification and aerobic degradation for quinoline of these strains was determined. Then the ability of denitrifying degradation of quinoline by selected denitrifying strains was measured. The results showed that 10 strains of isolates, which belong to Bacillus, Staphylococcus, Pseudomonas, Brucella and Delftia, were denitrifying bacteria. Whereas, 9 strains of isolates belonging to Rhodococcus had the ability of quinoline degradation under aerobic condition. This work described the metabolism function of the major predominant bacteria of microbial community in a quinoline degrading bioreactor. Diverse bacteria, in terms of metabolism, existed in the anoxic denitrifying bioreactor.
