It was isolated from a thermophilic methanol-degrading, sulfate-reducing bioreactor. This organism can convert methanol to CO2 (and partly to alanine) using thiosulfate or elemental sulfur as electron acceptors. The oxidation of methanol is more efficient when Thermotoga lettingae grows in a syntrophic culture with Methanothermobacter thermautotrophicus or Thermodesulfovibrio yellowstonii. The optimum pH, NaCl concentration, and temperature for growth are 7.0, 10%, and 65 degrees Celsius, respectively. In pure culture, strain TMO is also able to ferment methanol to acetate, CO2 and H2. However, this degradation occurs slower than in syntrophic cultures or in the presence of electron acceptors. Besides growing on methanol, strain TMO grows by fermentation on a variety of carbohydrates including monomeric and oligomeric sugars, starch and xylan. Acetate, alanine, CO2, H2, and traces of ethanol, lactate and alpha-aminobutyrate are produced during glucose fermentation. Comparison of 16S rDNA genes reveals that strain TMO is related to Thermotoga subterranea (98%) and Thermotoga elfii (98%). On the basis of the fact that these organisms differ physiologically from strain TMO, it is proposed that strain TMO be classified as a new species, within the genus Thermotoga, as Thermotoga lettingae."xsd:string |
