An anaerobic, facultatively autotrophic arsenite oxidizing bacterium that respires nitrate or nitrite. The cells are short motile rods. It was isolated from bottom waters of Mono Lake, California USA, a stratified soda lake with high pH and high salt levels. It is a gamma-Proteobacterium located in the Ectothiorhodospira clade of photosynthetic bacteria that occur in soda lakes. However, strain MLHE-1 is not a phototroph, but does grow as an anaerobic chemoautotroph by linking oxidation of arsenite (As III), hydrogen, or sulfide to the reduction of nitrate. It contains Form 1 RuBisCo genes for fixation of CO2 during chemoautotrophic growth, but can also grow as a heterotroph on acetate either with nitrate or air. However, arsenite is only oxidized under anaerobic conditions. This strain is very likely to be helpful to our understanding of As-mobility in subsurface waters.
