摘要：

A bacterial strain CT3 with a unique ability to degrade anthropogenic toxic compounds epsilon-caprolactam, toluene, and meta-xylene as sole sources of carbon and energy was isolated from the activated sludge of a municipal wastewater treatment plant. Based on sequencing and phylogenetic analysis of its 16S rRNA gene, the isolate was identified as a Pseudomonas putida strain. P. putida strain CT3 was found to possess a conjugative megaplasmid (similar to 550 kb) responsible for epsilon-caprolactam degradation to the TCA cycle intermediates. The genes encoding toluene and meta-xylene oxidation via the TOL pathway are localized on the chromosome.
