ERWINIA CAROTOVORA

Class: Gamma Proteobacteria
Genus: Erwinia
Species: Erwinia carotovora
Description: Erwinia carotovora known as “Pectobacterium carotovorum”. Erwinia carotovora is a Gram-negative, rod shaped bacterium that was named after the crop of carrots from which it was first isolated.Rods shaped,Motile by means of peritrichous flagella. No capsules present.
Synonyms: Pectobacterium carotovorum;Bacterium carotovorum;Bacillus carotovorus.
Source: These widespread microbes can be found in soil, guts of insects, water and suspended aerosols in air.
Pathogenicity: The bacterium infects a variety of vegetables and plants including carrots, potatoes, cucumbers, onions, tomatoes, lettuce and ornamental plants like iris. I causes a rapid soft rot of roots,rhizomes, fruits and the fleshy stems of a variety of plants.Erwinia carotovora causes death by creating an osmotically fragile cell. It produces extracellular pectic enzymes that destroy the integrity of the pectin. To a lesser extent, it produces an extracellular cellulase to degrade cellulose. Other exported enzymes thought to be important in pathogenesis include hemicellulases, arabanases, xylanases and a protease.
