| Abstract |
Quinoline (Q) and some isomers of methylquinoline (MQ) were transformed to hydroxylated products in freshwater sediment slurries incubated under methanogenic conditions at 25 C. Methylquinoline transformation was not affected by a methyl group on the C-3 or C-4 carbon atom of the pyridine ring; 2-MQ, however, was not transformed. The transformations of Q and MQs were pH dependent with an optimal pH of 7-8. The results of the study suggest that two pathways may exist for the anaerobic transformation of quinoline; one pathway leads to the formation of a hydroxylated intermediate and the other to a methylated and hydroxylated intermediate. In addition, the results suggest that a methyl substituent on the number 2 carbon inhibits the anaerobic transformation of quinoline derivatives. |
