Proteomes · Corynebacterium glutamicum (strain R)

Description

Bacteria from the genus Corynebacterium are Gram-positive, nonmotile rods which include both pathogenic and non-pathogenic species that can live in a large variety of habitats. In addition to being animal and human pathogens, they have been isolated from soil, plant material, waste water, and dairy products. Corynebacterium glutamicum (Strain R) is a facultative aerobic, non-sporulating, non-motile, saprophytic bacterium phylogenetically associated with the Actinobacteria. C. glutamicum was isolated from meadow soil in Japan. It is a well-studied soil bacterium of considerable importance in biotechnology, in particular for the fermentative production of L-amino acids for food and fodder industry. The name was originaly given for this species for its ability to produce significant quantities of glutamic acid, an important food enhancer that has a meaty taste and flavor. C. glutamicum is currently used commercially to produce glutamate and other amino acids (L-lysine) and compounds. Like Mycobacteria, Corynebacteria have an unusual outer membrane approximately 8nm thick, despite being considered Gram-positive. The outer membrane and the mycolic acid-arabinoglactan-peptidoglycan polymer form the cell wall, which constitutes an efficient permeability barrier in conjunction with the cell inner membrane.
