ABSTRACT
Seven strains belonging to genus Pseudomonas were isolated from an enrichment with hydrocarbon mixtures. Tests for enzyme activities showed that five strains used predominantly the catabolic meta-pathway for aromatic hydrocarbon degradation. Furthermore, the xylE gene which encodes a catechol 2,3-dioxygenase was amplified by PCR, and in two strains the nahAc gene, a key enzyme for naphthalene catabolism, was also found. The xylE gene might be a good marker to identify aromatic hydrocarbon degrading bacteria in soils from Patagonia.
