Gram-negative rods. Motile.
Colonies are 1-2 mm in diameter after 17h incubation at 28 ºC in TY medium (5g
tryptone/l , 3g yeast extract/l and agar 1.5%).
tryptone/l , 3g yeast extract/l and agar 1.5%).
Isolated from potato plant (Solanum tuberosum) in France.
Produces soft rot and blackleg symptoms on tubers and stems of potato plants.

wasabiae to Pectobacterium parmentieri sp. nov. Int J Syst Evol Microbiol 2016; 66:5379-5383.
Biochemically very similar to Pectobacterium wasabiae.
P. parmentieri can be differentiated from P. wasabiae by the ability to use raffinose, alpha-lactose, galactose and melibiose as sole
source of carbon and no fermentation of raffinose.
Positive results for acid production from maltose. Utilizes raffinose, alpha-D-lactose, D-galactose and melibiose.
Negative results for acid production from alpha-methyl-glucoside, raffinose and D-xylose. No utilization of methyl
alpha-D-glycopyranoside, maltose or malonic acid.
Variable results for acid production from mannose, mannitol, raffinose, sucrose, sorbitol and trehalose.
