[Structural and functional variability of genetic systems for catabolizing polycyclic aromatic hydrocarbons in Pseudomonas putida strains].
The genetic control of naphthalene, phenanthrene, and anthracene biodegradation was studied in three Pseudomonas putida strains isolated from coal tar- and oil-contaminated soils. These strains isolated from different geographical locations contained similar catabolic plasmids controlling the first steps of naphthalene conversion to salicylate (the nah1 operon), functionally inoperative salicylate hydroxylase genes, and genes of the metha-pathway of catechol degradation (the nah2 operon). Salicylate oxidation in these strains is determined by genes located in trans-position relative to the nah1 operon: in strains BS202 and BS3701, they are located on the chromosome, and in the strain BS3790, on the second plasmid.
