Bacillus selenitireducens MLS10

Names Bacillus selenitireducens MLS10
Accession numbers NC_014219
Background B.selenitireducens was isolated from anoxic muds of Mono Lake, California, an alkaline, hypersaline, arsenic-rich lake. It is a short, non-spore-forming rod, an arsenate-respirer, a haloalkaliphile, and shows optimal growth at high salinity (24 - 60 g/L) and pH (8.5 - 10). It is the only well-described organism that can respire the highly toxic selenite (Se(4-)) in addition to arsenate, nitrate, nitrite, TMAO, fumarate, and has some capacity for microaerophilic growth. It is unable to grow with Se(6-) as the electron acceptor. It is capable of respiring elemental sulfur, and can also reduce elemental selenium to selenide (Se(2-)). When grown on selenite, B. selenitireducens produces intracellular and extracellular nanoparticles of elemental selenium (Se(0)). It has potential in bioremediation (adapted from PMID and (EBI Integr8)
