Query: NC_006300:600516 Mannheimia succiniciproducens MBEL55E, complete genome
Lineage: Mannheimia succiniciproducens; Mannheimia; Pasteurellaceae; Pasteurellales; Proteobacteria; Bacteria
General Information: This bacterium was isolated from a bovine rumen. Succinic acid producing bacterium. This bacterium is able to produce a large amount of succinic acid from readily available agricultural byproducts. Succinic acid is an important component in the manufacture of synthetic resins and biodegradable polymers. Mannheimia succiniciproducens can grow on media which includes whey, a byproduct of the cheese industry which is normally discarded, and corn steep liquor (CSL), which is a byproduct of corn starch production. The organism has been able to produce production-level amounts of succinic acid in both batch and continuous cultures in media containing these inexpensive components.
Subject: NC_004547:1600900 Erwinia carotovora subsp. atroseptica SCRI1043, complete genome
Lineage: Pectobacterium atrosepticum; Pectobacterium; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
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.
