Identification of Aniline-assimilating Bacteria

Abstract

Twenty bacterial strains, grown on aniline as a sole source of carbon and nitrogen, and isolated from soil, were identified by morphological and biochemical tests, and cell wall analyses. Eight isolates were Rhodococcus erythropolis (Gray and Thornton) Goodfellow and Alderson, five were Pseudomonas maltophilia Hugh and Ryschenkow and seven were DAB (diaminobutyric acid)-type coryneform bacteria. The Rhodococcus spp. maintained the ability to assimilate aniline, but the pseudomonads and coryneform bacteria readily lost the ability, when grown in the absence of aniline.
