Desulfovibrio alaskensis belongs to the sulfate-reducing bacteria. The type strain is Al1^T (= NCIMB 13491^T = DSM 16109^T).^[1]

Biology

D. alaskensis has the ability to reduce radionuclides and heavy metals such as uranium and chromium to soluble and less toxic forms. The D. alaskensis strain G20 is an anaerobe with an optimal temperature range of 25C-40C. It is a gram negative microbe which is rod shaped, does not produce endospores, and is arranged in single cells. This strain is not known to cause any disease.

Genomics

Several strains of D. alaskensis have been sequenced: G20 (DOE JGI, 2007-2011^[2][3]), RB2256, and DSM 16109 (DOE JGI 2013^[4]).
