Brockia lithotrophica

Brockia lithotrophica is a thermophilic bacterium from the genus of Brockia which has been isolated from a sediment-water mixture from a hot spring in Uzon Caldera in Russia. 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 60 to 65 C for pH 6.5, but it is able to grow between 46 C and 78 C and pH ranging from 5.5 to 8.5.
