A bacterial strain which utilizes 3-methylquinoline as sole source of carbon, nitrogen and energy was isolated from activated sludge. On the basis of its morphological and physiological characteristics, this isolate was classified as Comamonas testosteroni. Four metabolites of 3-methylquinoline degradation were isolated from the culture supernatant and identified as 3-methyl-2-oxo-1,2-dihydroquinoline, 6-hydroxy-3-methyl-2-oxo-1,2-dihydroquinoline, 5,6-dihydroxy-3-methyl-2-oxo-1,2-dihydroquinoline and 2,5,6-trihydroxy-3-methylpyridine. Based on these results, a degradation pathway for 3-methylquinoline is proposed.
从活性污泥中分离出一株以3-甲基喹啉作为唯一碳源、氮源和能源的细菌菌株。根据其形态和生理特征，该分离菌株被归类为睾丸酮丛毛单胞菌。从培养上清液中分离出3-甲基喹啉降解的四种代谢产物，分别鉴定为3-甲基-2-氧代-1,2-二氢喹啉、6-羟基-3-甲基-2-氧代-1,2-二氢喹啉、5,6-二羟基-3-甲基-2-氧代-1,2-二氢喹啉和2,5,6-三羟基-3-甲基吡啶。基于这些结果，提出了3-甲基喹啉的降解途径。
