Desulfitobacterium hafniense is a species of gram positive bacteria, its type strain is DCB-2T.[1] ( NCBI taxonomy ID 272564; DSM 10664).
D. hafniense are anaerobic
Over the years several additional strains belonging to the hafniense species has been described from a diverse range of environments. Strains PCP-1, TCE1, DP7, TCP-A and G2 were originally published as members of a separate species Frappieri, but all are today considered as belonging to the hafniense species.[4][5]

Genomes
The genome of D. hafniense contains the machinery for both pyrrolysine and selenocysteine, making it the only known organism that potentially utilizes 22 amino acids in protein translation. [14] Desulfitobacterium hafniense strain DCB-2T has a single circular genome that contains 5.78 Mbp encoding 5,045 genes. The genome of Desulfitobacterium hafniense strain DCB-2T harbors seven genes encoding reductive dehalogenases, five of these seems to be functional and two are disrupted by mutations.[15]
Full genome sequence information is available for nine desulfitobacterium hafniense strains. They all have genome sizes ranging from 5 to 5,7 Mbp, none of the sequenced strains contains any plasmids. The genomes encodes only limited numbers of reductive dehalogenases, in addition to genes for utilizing a wide range of electron donors and acceptors.
