Query: NC_009342:2528426 Corynebacterium glutamicum R chromosome, complete genome Lineage: Corynebacterium glutamicum; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria General Information: This strain was isolated from meadow soil in Japan. Soil bacterium with industrial uses. They may be found as members of the normal microflora of humans, where these bacteria find a suitable niche in virtually every anatomic site. This organism 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 (>100 g per liter) of glutamic acid (glutamate), 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. The first strain of the species was isolated in 1957 by S. Kinoshita and colleagues while searching for an efficient glutamate-producer.

General Information: Use in fermentation of food products. A distinctive characteristic of pediococci is their ability to form tetrads via cell division in two perpendicular directions in a single plane. Like other lactic acid bacteria, species of Pediococcus are acid tolerant, cannot synthesize porphyrins, and possess a strictly fermentative (homofermentative) facultatively anaerobic metabolism with lactic acid as the major metabolic end product. They also occur in such food products as cured meat, raw sausages, and marinated fish, and are are used for biotechnological processing and preservation of foods. This bacterium can be isolated from a variety of plant materials and bacterial-ripened cheeses. This organism is used as an acid producing starter culture in the fermentation of some sausages, cucumbers, green beans, soy milk, and silage. Some strains have been reported to contain several (3-5) resident plasmids that render the bacterium capable of fermenting some sugars (raffinose, melibiose, and sucrose), as well as producing bacteriocins.
