Query: NC_003450:1770324 Corynebacterium glutamicum ATCC 13032, complete genome Lineage: Corynebacterium glutamicum; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria General Information: This strain (previously known as Micrococcus glutamicus) is the original strain isolated in the late 1950's. 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. 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: This strain (ATCC BAA-672) is a virulent blackleg isolated from the stem of a potato plant. Causative agent for blackleg and soft rot disease in potatoes. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Both Pectobacterium chrysanthemia and Pectobacterium carotovora cause soft-rot diseases of various plant hosts through degradation of the plant cell walls. Pectobacterium colonize the intercellular spaces of plant cells and deliver potent effector molecules (Avr - avirulence) through a type III secretion system (Hrp - hypersensitive response and pathogenicity). Avr proteins control host-bacterium interactions, including host range. Expression of the plant cell-wall-degrading enzymes is controlled through a quorum-sensing mechanism that quantifies the number of Pectobacterium bacteria through measurement of the concentration of small molecules (acyl homoserine lactones) produced by Pectobacterium. Pectobacterium atrosepticum is an environmentally widespread organism that causes blackleg and soft rot disease in potatoes. This organism produces pectolytic enzymes that destroy plant tissue and allow the bacteria to spread.
