proteamaculans (Paine and Stansfield 1919) Grimont et al. 1978.
Old synonym: Pseudomonas proteamaculans Paine and Stansfield 1919.
Initially S. proteamaculans and S. liquefaciens were thought to be synonymous based on DNA relatedness, but they remained
distinct species.

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 not produced. Facultatively anaerobic, growth
temperature 20-35 ºC (range may vary from 10 to 40 ºC). Doesn't require growth
factors.
with an entire margin. Prodigiosin is not produced. Facultatively anaerobic, growth
temperature 20-35 ºC (range may vary from 10 to 40 ºC). Doesn't require growth
factors.
Found in the natural environment (plants, wild rodents, insects, and water), rarely from human clinical specimens.
Considered to be a human pathogen. Also isolated from a leaf spot disease of Protea cynaroıdes.
