Gram-negative rods.
Colonies on nutrient agar are small, round-shaped, white, opaque and flat, 0.5-1 mm in
diameter after 17 hours. Pectinolytic. Grow at 37 ºC and on Luria–Broth with 5% NaCl.

Isolated from potato stems in Finland, Poland and the Netherlands.
Has a low maceration ability on potato tuber tissue and inhibit growth of Dickeya solani in dual culture.
