Flavobacterium glaciei is a type of bacteria . The species is one of the Bacteroidetes .

features

The species Flavobacterium glaciei is Gram-negative . The cells are rod-shaped. The length is between 2.7 and 6.3 µm, the width between 0.45 and 0.55 µm. There are no flagella . The species depends on oxygen , so it is absolutely aerobic . Flavobacterium glaciei is psychrophilic ("likes the cold"), it was isolated from the bottom of a glacier , hence the species name "glaciei" (glacier). Growth takes place at 4–25 ° C, 21 ° C is the optimal temperature. The pH values ​​are between 6 and 9, the optimum at 6.5 to 7.5. The GC content in the DNA is 36.5%.

etymology

The genus name Flavobacterium is based on the Latin word "Bacterium" (bacterium) and the Latin word "flavus", which means yellow. The latter refers to the colors of the colonies, which range from relatively pale to pronounced yellow. "Glaciei" is also a Latin word and means ice cream. The bacterium was found in the frozen ground on a glacier in China. It is a relatively simple and closed ecosystem there . Several new bacterial species that specialize in cold environments (i.e. are psychrophilic) have been isolated on the same glacier. Examples are Flavobacterium omnivorum and Flavobacterium xinjiangense , described by Fei Zhu and co-workers, and Planomicrobium glaciei , discovered by De-Chao Zhang .
