| Popis: | 4′-Dimethylaminoazobenzene-2-carboxylic acid (DMBC) was utilized as a necessary carbon and nitrogen source by Pseudomonas stutzeri IAM 12097. o-Aminobenzoic acid (o-ABA), N,N-dimethyl-p-phenylenediamine (DMPA) and cathecol were identified as intermediates of DMBC degradation. DMBC was degraded at a concentration below 70 μmol dm−3. The ability to utilize DMBC in P. stutzeri was lost spontaneously to some extent. When P. stutzeri was cured of plasmid DNA (approximately 8 MDal) by treatment with mitomycin C, acridine orange, and chloramphenicol, DMBC was not utilized by the resultant strain. These facts suggest that the degradative ability on DMBC in P. stutzeri is controlled by plasmid DNA. |
