Query: NC_008554:3177723 Syntrophobacter fumaroxidans MPOB, complete genome
Lineage: Syntrophobacter fumaroxidans; Syntrophobacter; Syntrophobacteraceae; Syntrophobacterales; Proteobacteria; Bacteria
General Information: This organism is a syntrophic propionate-oxidizing bacterium isolated from granular sludge from an anaerobic sludge bed reactor treating sugar-beet processing wastewater. Propionate-oxidizing bacterium. This organism is able to oxidize propionate when grown in co-culture with hydrogen-consuming methanogens (syntrophic metabolism). This organism can also ferment fumarate when not in co-culture.
Subject: NC_007406:632436 Nitrobacter winogradskyi Nb-255, complete genome
Lineage: Nitrobacter winogradskyi; Nitrobacter; Bradyrhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Nitrite-oxidizing bacterium. Members of this genus are found in marine, freshwater, and terrestrial habitats, often in association with ammonia-oxidizing bacteria. These organisms oxidize nitrate, generated by the oxidation of ammonia, to nitrate and play an important role in the global nitrogen cycle. The enzyme involved in nitrite oxidation, nitrite oxidoreductase, can also reduce nitrate to nitrite in the absence of oxygen, allowing Nitrobacter sp. to grow anaerobically. Nitrobacter winogradskyi is commonly isolated from soil, fresh and sea water, sewage, and compost. This organism can grow anaerobically using nitrate as the electron acceptor, forming nitrite, nitric oxide, and nitrous oxide.
