Query: NC_016894:77853 Acetobacterium woodii DSM 1030 chromosome, complete genome 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.

General Information: An endosymbiont of free-living amoebae (Acanthamoeba sp. endosymbiont UWE25) and implicated as a potential human pathogen this strain is an environmental isolate. Amoeba endosymbiont. Bacteria belonging to the Chlamydiales group are obligate intracellular parasites of eukaryotic cells. They are found within vertebrates, invertebrate cells, and amoebae hosts. Chlamydiae are one of the commonest causes of sexually transmitted diseases (STDs) and if left untreated may cause infertility in women. They are transmitted by direct contact or aerosols, and can cause various diseases, while also being able to coexist with the host in an apparently asymptomatic state. Candidatus Protochlamydia amoebophila, originally Parachlamydia is an endosymbiont of free-living amoebae (Acanthamoeba). This organism is an obligate intracellular endosymbiont and lives in small inclusions dispersed throughout the host cell.
