Query: NC_014034:1507047 Rhodobacter capsulatus SB1003 chromosome, complete genome Lineage: Rhodobacter capsulatus; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria General Information: This strain is a derivative strain isolated in the laboratory of Barry Marrs from the classical progenitor strain B10. It is rifampicin-resistant, produces GTA, and is capable of growing under high illumination (resistant to photooxidative killing). Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to use photosynthesis and usually can grow under both anaerobic and aerobic conditions. This organism is a facultatively phototrophic purple non-sulfur bacterium and the type species of the Rhodobacter group. The colony's color depends largely on the amount of oxygen present in its environment. While it is able to produce cellular energy in a number of different ways, it can rely on anoxygenic photosynthesis under anaerobic conditions in the presence of light. Some strains produce the Gene Transfer Element (GTA), a pro-phage particle capable of transferring genetic material between strains.

General Information: Country: United Kingdom; Isolation: Sick cider; Temp: Mesophile. The natural habitat of this organism includes sugar-rich plant saps where the bacterium ferments sugar to ethanol. The high conversion of sugars to ethanol makes this organism useful in industrial production systems, particularly in production of bioethanol for fuel. A recombinant strain of this bacterium is utilized for the conversion of sugars, particularly xylose, which is not utilized by another common sugar-fermenting organism such as yeast, to ethanol. Since xylose is a common breakdown product of cellulose or a waste component of the agricultural industry, it is an attractive source for ethanol production. Zymomonas mobilis was chosen for this process as it is ethanol-tolerant (up to 120 grams of ethanol per litre) and productive (5-10% more ethanol than Saccharomyces). This bacterium ferments using the Enter-Doudoroff pathway, with the result that less carbon is used in cellular biomass production and more ends up as ethanol, another factor that favors this organism for ethanol production.
