This bacterium is rod shaped, spore-forming and obligate anaerobe. It is lithoautotroph and grows on a mineral medium with molecular sulfur, thiosulfate or polysulfide; it has optimal growth temperature in the range of  for pH 6.5, but it is able to grow between  and  and pH ranging from 5.5 to 8.5.
