Carr et al. 2003.
Gram-negative coccobacilli. Nonmotile. Nonsporulated.
Colonies on nutrient agar are circular, convex, smooth and slightly opaque.
Nonhemolytic on horse blood agar, but Nemec et al. reported hemolysis
production by type strain). Growth occurs at 37 ºC, but not at 41 ºC. Aerobic.
Isolated from activated sludge in Victoria, Australia.
Undetermined.
