| Abstract: | Abstract This paper is the first to describe the transformation of 3-hydroxybenzoate (3-HBA) by Pseudomonas putida BS893 by a new pathway via 2,3-dihydroxybenzoate (2,3-DBA) and catechol. We have compared the intermediates and appropriate enzyme activities in P. putida BS893 (pBS241) and in a cured derivative BS662 (Bph−) thereof, for the ascertainment of plasmid or chromosomal genetic control over 3-HBA-catabolism. The results presented show that catabolism of 3-HBA in P. putida BS893 (pBS241) is controlled by chromosomal genes. |
