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_006177:3457637 Symbiobacterium thermophilum IAM 14863, complete genome

Lineage: Symbiobacterium thermophilum; Symbiobacterium; Shewanellaceae; Clostridiales; Firmicutes; Bacteria

General Information: This symbiotic and thermophilic bacterium was discovered by screening for thermostable tryptanophases in Japanese compost. Cultured growth of this organism requires the presence of another bacterial species, such as a Bacillus or Escherichia coli, which provides diffusable metabolites required for its growth. Pure cultures can be obtained by growing Symbiobacterium thermophilum in a bioreactor, separated from its symbiotic counterpart by a dialysis membrane. Because of its symbiotic nature, it cannot be cultured with conventional methods. Despite a negative reaction for gram stain, this species is placed with the gram-positive bacteria based on 16s phylogenetic analysis.
