Catabolism of biphenyl by Pseudomonas putida BS 893 strain containing the biodegradation plasmid pBS241

: The isolation and identification of biphenyl catabolism products in Pseudomonas putida BS 893 (pBS241) showed the presence of benzoic, m-hydroxybenzoic and cinnamic acids. The two latter compounds were not found in biphenyl degradation by other bacterial strains. P. putida BS 893 (pBS241) differed from other biphenyl-positive Pseudomonas strains in the enzyme activity. These differences may stem from peculiarities in the pathway of biphenyl catabolism controlled by plasmid pBS241.
