Researchers Sequence Dehalococcoides Strain CBDB1, Bacteria That Break Down Chlorinated Organic Pollutants

NEW YORK, Aug. 22 (GenomeWeb News) - A team of researchers from Germanyand the UShas sequenced the genome of Dehalococcoides sp. strain CBDB1, anaerobic bacteria that break down many of the most toxic and persistent chlorinated organic chemicals.

 

The microbe's 1,395,502 base pair genome contains 32 reductive-dehalogenase-homologous genes, possibly giving it its immense dehalogenating potential. A comparison with the recently sequenced genome of Dehalococcoides ethenogenes strain 195 revealed a high degree of gene context conservation but also high plasticity in regions containing rdh genes.

 

The scientists, from the Max-Planck-Institute of Molecular Genetics in Berlin, Technical UniversityBerlin, and CornellUniversity, published their study yesterday online in Nature Biotechnology.
