Query: NC_014751:449001 Mycoplasma leachii PG50 chromosome, complete genome
Lineage: Mycoplasma leachii; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: Mycoplasma leachii, formerly Mycoplasma sp. 'bovine group 7', was originally isolated from cattle suffering from arthritis and mastitis in Australia. Mycoplasma leachii is part of the mycoides cluster like Mycoplasma mycoides SC and Mycoplasma capricolum, but it can infect both bovine and caprine hosts.
Subject: NC_018870:1417851 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.
