Pseudomonas trivialis Behrendt et al. 2003.
Pseudomonas trivialis Behrendt et al. 2003.
Gram-negative, non-sporeforming rods, motile by one polar flagellum, 1.6–3.3 x 0.8 µm.
Aerobic, optimal growth temperature 21 °C. Media: Trypticase Soy Agar, Nutrient agar,
King’s agar A & B. Colonies are colourless, translucent smooth with regular margins
and produce on King A and B media a pigment with light yellow-green fluorescence
on UV light. Growth can be observed at 4 °C, but none of the isolates is able to grow
at 41 °C. Non-haemolytic on sheep blood agar.

Isolated from the phyllosphere of grasses in Germany. No ice nucleation activity presented.
Possible plant pathogen.
