rdf:langString Acidobacterium capsulatum

rdf:langString Acidobacterium capsulatum is a bacterium. It is an acidophilic chemoorganotrophic bacterium containing menaquinone. It is gram-negative, facultative anaerobic, mesophilic, non-spore-forming, capsulated, saccharolytic and rod-shaped. It is also motile by peritrichous flagella. Its type strain is JCM 7670. They can grow between pH 3.0 and 6.0, but not at pH 6.5. They give positive results in esculin hydrolysis, β-galactosidase and catalase tests and are negative in oxidase and urease tests. They can use glucose, starch, cellobiose, maltose as a sole carbon source, but cannot use elemental sulfur and ferrous iron as an energy source. Another characteristic of this organism is the presence of high amounts of exopolysaccharides coating the cells from soil isolates. Presence of exopolysaccharides helps in increased adhesion and allow the bacterium to acquire nutrients more readily from the environment.
