A bacterial strain, SL-1T, capable of degrading trichloroethene was isolated from a laboratory enrichment in the Department of Civil and Environmental Engineering, University of Washington, USA. The material in the enrichments was derived from a soil sample from Seattle, WA, USA. Strain SL-1T was capable of using phenol as a source of carbon and energy. Chemotaxonomic, morphological, physiological and phylogenetic analyses showed that strain SL-1T is a member of the genus Pseudonocardia. The ability of strain SL-1T to utilize phenol and degrade trichloroethene, as well as other phenotypic properties and the results from a 16S rRNA phylogenetic analysis, led to the proposal of a novel species, Pseudonocardia chloroethenivorans sp. nov. The type strain is SL-1T (=ATCC BAA-742T=DSM 44698T). Trichloroethene and other chloroethenes are major pollutants at many environmental sites, and P. chloroethenivorans has biodegradation properties that should be of interest to environmental microbiologists and engineers.
Published online ahead of print on 4 July 2003 as DOI 10.1099/ijs.0.02488-0.
The GenBank accession number for the 16S rRNA gene sequence of Pseudonocardia chloroethenivorans SL-1T is AF454510.
