General Information: Thermotoga lettingae strain TMO was isolated from a methanol-degrading, sulfate-reducing bioreactor. Thermophilic, methanol-degrading organism. This organism, a member of the Thermotogales, has the characteristic sheath-like envelope which extends beyond the cell wall. The oxidation of methanol was more efficient when Thermotoga lettingae was grown as a co-culture with Methanothermobacter thermautotrophicus or Thermodesulfovibrio yellowstonii.
