Gram-negative straight rods, 2.0-4.2 x 0.5-1.0 µm. Motile.
Colonies are circular, convex, granular, dry and dark yellow and 0.8-2.0 mm in
diameter after 3 days incubation on Nutrient Agar at 28 ºC, colonies are. The
maximum growth temperature is 37-40 ºC in NB and 41-42 ºC in TSB. Not haemolytic
on sheep blood agar. Facultatively anaerobic. Grows in medium containing KCN.

entomopathogenic nematode Steinernema aciari. Int J Syst Evol Microbiol 2013; 63:1690-1695.
Positive results for citrate (Simmons), esculin hydrolysis, gelatin hydrolysis, Tween 20 and 80 hydrolysis, acid production from
esculin, D- fructose, glycerol, D-glucose, 5-ketogluconate (weak), D-mannose, mannitol, maltose, N-acetylglucosamine, D-ribose
(weak), salicin (weak), trehalose, and xylitol.
Can utilize acetate, glucosamine, malonate, tartrate, D-fructose, D-mannose, N-acetylglucosamine, esculin, trehalose, starch,
glycogen, 5-ketogluconate, glycerol (weak), arbutin (weak) and salicin (weak).
Negative results for catalase, DNase, indole production, methyl-red test, beta-galactosidase, oxidase, phenylalanine deaminase,
urease, Voges–Proskauer reaction and other API 20 E tests, acid production from inositol, sorbitol and other API 50 CH tests.
No utilization of glucose, inositol and maltose.
