Query: NC_018870:81396 Thermacetogenium phaeum DSM 12270 chromosome, complete genome

Lineage: Thermacetogenium phaeum; Thermacetogenium; Thermoanaerobacteraceae; Thermoanaerobacterales; Firmicutes; Bacteria

General Information: Nitrogen fixation. Thermophilic strictly anaerobic bacterium oxidizing acetate to CO2 in syntrophic association with a methanogenic partner. Capable of growing with various substrates such as alcohols and methylated nitrogen compounds, and to reduce sulfate in the presence of acetate. Isolated from sludge of an anaerobic digester run at 58 degrees C. Thermacetogenium phaeum is a strictly anaerobic, homoacetogenic bacterium. It is exceptional because it can use the homoacetogenic Wood-Ljungdahl (CO- dehydrogenase) pathway both for acetate formation and acetate oxidation. Acetate oxidation is possible only in syntrophic cooperation with a methanogenic partner which maintains a low hydrogen and/or formate concentration in the coculture. With this, the bacterium operates close to the thermodynamic equilibrium of substrate conversion, similar to other syntrophically fermenting bacteria such as Syntrophomonas wolfei the genomes of which have been sequenced as well in the recent past.

Subject: NC_018664:3009166 Clostridium acidurici 9a chromosome, complete genome

Lineage: Gottschalkia acidurici; Gottschalkia; ; Clostridiales; Firmicutes; Bacteria

General Information: Clostridium acidiurici is an obligate anaerobic Gram-positive bacterium that is motile and spore-forming. It can be isolated from almost every soil but can also be found in the intestinal tract of birds. It is able to use purines like uric acid as sole carbon, nitrogen and energy source to build ammonia, carbon dioxide and acetic acid. Unlike most other Clostridia it is a specialist and not able to grow on sugars or different other substrates than purines.
