Query: NC_006677:1596560 Gluconobacter oxydans 621H, complete genome
Lineage: Gluconobacter oxydans; Gluconobacter; Acetobacteraceae; Rhodospirillales; Proteobacteria; Bacteria
General Information: Industrially useful bacterium. Gluconobacter oxydans is a member of the Acetobacteraceae family within the alpha proteobacteria and can be isolated from flowers, fruits, and fermented beverages. This organism uses membrane-associated dehydrogenases to incompletely oxidize a wide variety of carbohydrates and alcohols. Oxidation occurs in the periplasm with the products being released into the medium via outer membrane porins and the electrons entering the electron transport chain. Able to oxidize large amounts of substrates, making it useful for industrial purposes. Among other applications, it has been used to produce 2-ketogluconic for iso-ascorbic acid production, 5-ketogluconic acid from glucose for tartaric acid production, and L-sorbose from sorbitol for vitamin C synthesis.
Subject: NC_015957:10505870 Streptomyces violaceusniger Tu 4113 chromosome, complete genome
Lineage: Streptomyces violaceusniger; Streptomyces; Streptomycetaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Environment: Soil, Terrestrial; Temp: Mesophile. Streptomyces violaceusniger 16S rRNA gene clade form a gray aerial spore mass and a grayish-yellow substrate mycelium on oatmeal agar, and produce aerial hyphae that differentiate into spiral chains of rugose ornamented spores. The characteristic earthy smell of freshly plowed soil is actually attributed to the aromatic terpenoid geosmin produced by species of Streptomyces. There are currently 364 known species of this genus, many of which are the most important industrial producers of antibiotics and other secondary metabolites of antibacterial, antifungal, antiviral, and antitumor nature, as well as immunosuppressants, antihypercholesterolemics, etc. Streptomycetes are crucial in the soil environment because their diverse metabolism allows them to degrade the insoluble remains of other organisms, including recalcitrant compounds such as lignocelluloses and chitin.
