Desulfitobacterium hafniense is a species of gram positive bacteria, its type strain is DCB-2T. ( NCBI taxonomy ID 272564; DSM 10664). D. hafniense are anaerobic spore-forming bacteria. The majority of the described isolates are facultatively organohalide respiring bacteria capable of reductive dechlorination of organohalides such as chlorophenols, and tetrachloroethene. The cells of D. hafniense are rod-shaped and 3.3 to 6 μm long by 0.6 to 0.7 μm wide, they are motile, each cell having one or two terminal flagella. All tested strains are resistant to the antibiotic vancomycin. Genomes
