Plasmid determined degradation of sulfo-aromatic compounds by Pseudomonas sp. BS1304]

Utilized sulfo-aromatic compounds of Pseudomonas sp. BS1304 were isolated. It was shown that the first step of conversion is desulfonation with following meta-cleavage of the substituted aromatic ring. At least two steps are controlled by the plasmid pBS1004 (120 kb), belonging to the IncP-9 incompatibility group. The degradative plasmid marked by Tn5-lac may be mobilized to P. putida, P. aeruginosa, P. mendocina, where a degradative phenotype is expressed.
