Gram-negative, non-sporeforming, rod-shaped cells,motile by one polar flagellum,
2.5–3.3 µm wide and about 0.8 µm long.
Aerobic, optimal growth temperature 21 ºC. Growth can be observed at 4 ºC, but not at
41 ºC. Media: Trypticase Soy Agar, Nutrient agar, King’s agar A & B. Produce a
fluorescent pigment.
Type strain was isolated from the phyllosphere of grasses in Germany. No ice nucleation activity.
Possible plant pathogen.
