TAXONOMY: cellular organisms -> Bacteria -> Proteobacteria -> Gammaproteobacteria -> Enterobacteriales -> Enterobacteriaceae -> Pectobacterium
Straight rods, 0.5–1.0 × 1.0–3.0 µm, rounded ends; occur singly or in pairs. Gram-negative. Motile by peritrichous flagella. Fermentative. Facultatively anaerobic. Optimum growth temperature, 27–30°C; maximum temperature for growth is 40°C. Oxidase negative. Catalase positive. Acid is produced from N-acetyl-glucosamine, fructose, d-galactose, d-glucose, d-mannose, l-rhamnose, d-ribose, salicin, and sucrose but not from adonitol, l-arabitol, d-lyxose, α-methylmannoside, l-sorbose, starch, or d-tagatose. Utilize acetate, arbutin, fructose, fumarate, d-galactose, d-glucose, glycerol, malate, d-mannitol, mannose, β-methylglucoside, ribose, salicin, succinate, and sucrose but not adipate, benzoate, betaine, butanol, gallate, methanol, oxalate, propionate, or sorbose as carbon and energy-yielding sources. Utilize l-alanine, allantoin, γ-aminobutanic acid, ammonium chloride, arginine, asparagine, asparaginic acid, citrulline, glucosamine, glutamine, l-glutaminic acid, glutathione, glycine, glycylglycine, histidine, leucine, l-methionine, phenylalanine, l-serine, l-tryptophan, tyrosine, and urea, but not anthranilic acid, betaine, choline, cysteamine, hydroxyproline, kynureninic acid, quinolinic acid, sarcosine, spermidine, spermine, trigonelline, or trimethylammonium as nitrogen sources. No decarboxylases are formed for arginine, lysine or ornithine. Do not possess tryptophan deaminase or urease. Hydrolyze esculin but not starch.
The mol% G + C of the DNA is: 50.5–56.1.
