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_008525:270310 Pediococcus pentosaceus ATCC 25745, complete genome
Lineage: Pediococcus pentosaceus; Pediococcus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Use in fermentation of food products. A distinctive characteristic of pediococci is their ability to form tetrads via cell division in two perpendicular directions in a single plane. Like other lactic acid bacteria, species of Pediococcus are acid tolerant, cannot synthesize porphyrins, and possess a strictly fermentative (homofermentative) facultatively anaerobic metabolism with lactic acid as the major metabolic end product. They also occur in such food products as cured meat, raw sausages, and marinated fish, and are are used for biotechnological processing and preservation of foods. This bacterium can be isolated from a variety of plant materials and bacterial-ripened cheeses. This organism is used as an acid producing starter culture in the fermentation of some sausages, cucumbers, green beans, soy milk, and silage. Some strains have been reported to contain several (3-5) resident plasmids that render the bacterium capable of fermenting some sugars (raffinose, melibiose, and sucrose), as well as producing bacteriocins.
