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_006371:1997954 Photobacterium profundum SS9 chromosome 2, complete sequence

Lineage: Photobacterium profundum; Photobacterium; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria

General Information: Isolated at a depth of 2500 m from the Sulu Trough. High pressure tolerant bacterium. This bioluminescent genus was originally identified in 1878 in association with hake (a marine fish) in Cape Town, South Africa. This species was originally isolated from an amphipod homogenate enrichment from the Sulu Sea. It is a genetically tractable model system for studies of low temperature and high pressure adaptation, and has been used in studies of mono- and polyunsaturated fatty acid production under these conditions.
