Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="jobm201200369-sec-0001" sec-type="section"> <p>This study was focused on the characterization of 15 bacterial strains isolated from long‐term PCB‐contaminated sediment located at the Strážsky canal in eastern part of Slovakia, in the surroundings of a former PCB producer. PCB‐degrading strains were isolated and identified as <italic>Microbacterium oleivorans</italic>, <italic>Stenotrophomonas maltophilia</italic>, <italic>Brevibacterium</italic> sp., <italic>Ochrobactrum anthropi</italic>, <italic>Pseudomonas mandelii</italic>, <italic>Rhodococcus</italic> sp., <italic>Achromobacter xylosoxidans</italic>, <italic>Stenotrophomonas</italic> sp., <italic>Ochrobactrum</italic> sp., <italic>Pseudomonas aeruginosa</italic>, and <italic>Starkeya novella</italic> by the 16S rRNA gene sequence phylogenetic analysis. This study presents a newly isolated bacterial strain <italic>S. novella</italic> with PCB‐degrading ability in liquid medium as well as in sediment. For <italic>A. xylosoxidans</italic>, the <italic>bphA</italic> gene was identified. The best growth ability in the presence of all sole carbon sources (biphenyl and PCBs vapor) was obtained for <italic>Ochrobactrum</italic> sp. and <italic>Rhodococcus</italic> sp. Uncultured <italic>Achromobacter</italic> sp. showed the highest potential for bioaugmentation of PCB‐contaminated sediment.</p> </sec> </abstract>
