Lineage: Acetobacterium woodii; Acetobacterium; Eubacteriaceae; Clostridiales; Firmicutes; Bacteria

General Information: Acetobacterium woodii is a Gram positive, motile, strict anaerobic, acetogenic bacterium, that relies on Na+ as coupling ion in bioenergetic reactions. The organism can use a wide range of substrates, such as sugars, alcohols, methoxylated aromatic acids or C1 compounds. Electrons derived from these electron donors are used in the Wood-Ljungdahl-pathway where the organism fixes CO2 and produces acetate. The pathway of CO2-fixation is coupled to energy conservation via a chemiosmotic mechanism, one enzyme that seems to be involved is the Rnf complex. The produced Na+ gradient can be used to drive ATP-synthesis or flagella rotation. The ATP synthase is a member of the F1FO class of enzymes and has an unusual hybrid rotor. Can use alternative electron acceptors like the lignin degradation product caffeate.

Subject: NC_007948:4646344 Polaromonas sp. JS666, complete genome

Lineage: Polaromonas; Polaromonas; Comamonadaceae; Burkholderiales; Proteobacteria; Bacteria

General Information: This strain was isolated from sediment contaminated with cis-dichloroethane (cDCE), a common pollutant resulting from widespread manufacture and use of industrial solvents. This bacterium is the only known organism capable of using cDCE as a sole carbon and energy source. The ability of this strain to convert ethene to epoxyethane suggests that the first step in the cDCE biodegradation pathway is the oxidation of cDCE to an epoxide compound. Bacteria that are able to grow on cDCE are rare, and have only been found in very few highly selective artificial environments. The discovery of this bacteria may provide a low cost, self-sustaining bioremediation method in areas where cDCE is a problem contaminant.
