Query: NC_009828:469778 Thermotoga lettingae TMO, complete genome Lineage: Thermotoga lettingae; Thermotoga; Thermotogaceae; Thermotogales; Thermotogae; Bacteria 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.

General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
