Names Dehalococcoides ethenogenes 195
Accession numbers NC_002936
Background Dehalococcoides species are strictly aerobic bacteria that catabolize several of the most toxic and persistent chlorinated aromatics and aliphatics by reductive dechlorination and are used for in situ bioremediation of contaminated sites. D.ethenogenes is able to reductively dechlorinate tetrachloroethene (PCE) and trichloroethene (TCE) to ethene. TCE and PCE are used as industrial cleaners and because of their disposal after use are amongst the most pervasive organic groundwater pollutants. Strain 195 was derived from an anaerobic sewage digestor. Its genome contains 17 genes coding for putative reductive dehalogenases. It was reported that strain 195 did not react with a peptidoglycan-specific lectin and that its ultrastructure resembled S-layer from Archaea (Maymo-Gatell et al., 1997). (HAMAP: DEHE1)
