Pseudomonas lundensis Molin et al. 1986.
Gram-negative, rods , 0.7-0.8 x 1.5-3 μm, motile by one polar flagellum,
asporogenous.
asporogenous.
Colonies on nutrient agar are smooth, circular, and non-pigmented. They are
non-hemolytic on ox blood agar and do not glide on cytophaga agar. Fluorescent
pigments (pyoverdine) are produced on King B agar. No accumulation of
poly-beta-hydroxybutyrate as intracellular inclusions.
Metabolism is respiratory and never fermentative. Oxygen is the terminal electron
acceptor; nitrate does not serve as an alternate
electron acceptor. The temperature range for growth is usually 0 to 33°C, but 30% of
the strains are capable of slow
growth at 37°C. The optimal growth temperature is 25°C. There is no growth at pH
4.5. No growth factors are required. Aerobic.
