Methylquinolines and related N-heterocyclic aromatic compounds are common contaminants associated with the use of hydrocarbons in both coal gasification and wood treatment processes. These compounds have been found in groundwater, and many are known mutagens. A stable, five-member bacterial consortium

4-Methylquinoline (4-MeQ) showed an extraordinarily potent mutagenicity when compared to quinoline and isomeric methylquinolines. The major metabolite of 4-MeQ was 4-hydroxymethylquinoline, which was not mutagenic under the assay condition employed. Deuteration of the methyl group of 4-MeQ resulted in a

Strain Lep1, isolated from a bacterial consortium capable of aerobic degradation of 4-methylquinoline (4-MQ), was chosen for further characterization as it was the only member of the consortium able to grow on 4-MQ in pure culture. Lep1 was identified as

The relative tumorigenic activity of quinoline, 4-methylquinoline, 8-methylquinoline, and all three isomeric benzoquinolines was evaluated in newborn CD-1 mice and Sprague-Dawley rats. In the newborn-mouse bioassay, 0.25, 0.5 and 1.0 mumol of each compound in dimethylsulphoxide was administered by ip
