Abstract：As quinoline is a kind of recalcitrant organic compounds ,in this work ,three protocols ,direct biodegradation(B) ,biodegradation after UV photolysis(P+B) ,and biodegradation after adding oxalic acid into quinoline solution(OA+B) ,were employed for quinoline biodegradation .The experimental results in‐dicated that quinoline biodegradation and mineralization were accelerated by 27% and 40% by (P+B) than that by protocol B .Analysis on quinoline photolytic intermediates gives that oxalic acid generated during photolysis ,which hypothesize that oxalic acid released electrons to accelerate initial quinoline mono‐oxy‐genation reaction by means of co‐substrate .The hypothesis was valuated by protocol (OA+ B) ,in which the quinoline biodegradation and mineralization were similar to protocol (P+B) .
