| Abstract: | Conjugative plasmids control the ability of five Pseudomonas strains isolated from the rectifiers of chemical plants to grow on epsilon-caprolactam as a sole carbon and nitrogen source. All the plasmids have a high molecular mass of their DNA (ca. 300 MDa) and control epsilon-caprolactam degradation at least to succinate. One of the plasmids (pBS271) belongs to the incompatibility group P-2 and suppresses the growth of a broad spectrum of temperate and virulent P. aeruginosa bacteriophages as well as that of some P. putida bacteriophages. |
