Gluconobacter oxydans
Description and significance
Describe the appearance, habitat, etc. of the organism, and why it is important enough to have its genome sequenced. Describe how and where it was isolated. Include a picture or two (with sources) if you can find them. Gluconobacter oxydans, previously known as Acetobacter suboxydans, are Gram-negative rod or oval shaped bacterium ranging from about 0.5 to 0.8mm x to 4.2mm. They tend to have a small genome size because of their limited metabolic abilities. These abilites include partially oxidizing carbohydrates and alcohols through the process of oxidative fermentation, and they can be used for sythesis of Vitamin C, D-gluconis acid and ketogluconic acids. G. oxydans are found in flowers, fruits, garden soil, alcoholic beverages, cider, and soft drinks because they are capable of growing strains in high concentrations of sugar solutions and low pH values (optimal pH for growth is 5.5-6.0.) Although they are able to grow in extreme conditions, its growth rate is slow and the concentration of mature cells are low. The importance of G. oxydan is its ability to incompletely oxidize carbon substrates such as D-sorbitol, glycerol, D-fructose, and D-glucose for the use in biotechnological instruments.
Genome structure
