Gram-negative, straight rods, 0.5-0.8 x 0.9-2.0 μm, non-sporulated. Some strains are
capsulated. Motile by peritrichous flagella.
capsulated. Motile by peritrichous flagella.
Colonies are 1 to 3 mm in diameter, circular, shiny, opaque, cream-white and smooth
with an entire margin. Prodigiosin is produced by most strains. Facultatively anaerobic,
growth temperature 20-35 ºC (range may vary from 10 to 40 ºC). The temperature of 37
ºC is not favorable for the isolation. Many tests that are positive at 28-35 ºC give negative
results at 37 ºC. Doesn't require growth factors.

Isolated from various plants and freshwater. Very rarely found in human sputum. Produces metabolites with antifungal activity.
No human infection reported.
