Biodegradation of aniline by Pseudomonas rhodesiae isolated from river water = 강물에서 분리한 Pseudomonas rhodesiae의 아닐린 분해

Abstract

Two Bacterial strains 1-C and 51-C capable of utilizing aniline as a sole source of carbon and energy were isolated from river waters. Both strains were identified as Pseudomonas rhodesiae based on their physiological and biochemical characteristics and 16S rRNA gene sequence. The strains were able to grow on the mineral salt media containing aniline at concentrations up to 6,000 ㎍/mL. Pseudomonas rhodesiae 51-C completely degraded aniline in a mineral salt medium containing 300 ㎍/mL of aniline as a sole carbon and energy source within 16 hours. The optimum pH and temperature for its growth and aniline degradation were 7.0 and 30℃∼35℃, respectively. This is the first report of aniline degradation by P. rhodesiae strains.
