Abstract
An aerobic bacterium was isolated from a subsurface sediment in a medium containing 2-methylaniline as sole C and N source. The isolate, Pseudomonas strain AK20, grew on aniline and all isomers of methylaniline. Aromatic amine metabolism was inducible, and cell extracts contained catechol-2,3-oxygenase which was also active against methylcatechols. Growth on aniline was rapid (μ = 0.41 h−1), and aniline and acetate were simultaneously utilized in mixed substrate cultures. Growth on 2-methylaniline was slower (μ = 0.1−0.17 h−1) and 2-methylaniline was not used simultaneously with other organic substrates unless it served as sole N source.
