Thermothrix azorensis

Thermothrix azorensis is a Gram-negative, facultatively chemolithoautotrophic, non-spore-forming, aerobic, thermophilic, sulfur-oxidizing bacterium of the genus Thermothrix, isolated from a hot spring on Sao Miguel Island in the Azores. T. azorensis uses thiosulfate, tetrathionate, hydrogen sulfide, and elemental sulfur for its sources of energy (chemolithoautotrophic).
