Microbial metabolism of quinoline and related compounds. VI. Degradation of quinaldine by Arthrobacter sp.
Quinaldine catabolism was investigated with the bacterial strain Arthrobacter sp., which is able to grow aerobically in a mineral salt medium with quinaldine as sole source of carbon, nitrogen and energy. The following degradation products of quinaldine were isolated from the culture fluid and identified: 1H-4-oxoquinaldine, N-acetylisatic acid, N-acetylanthranilic acid, anthranilic acid, 3-hydroxy-N-acetylanthranilic acid and catechol. 3-Hydroxy-N-acetylanthranilic acid was not further metabolized by this organism. A degradation pathway is proposed.
