Gram-negative rods, 0.8 x 2.5-3.0 µm. Slightly motile in soft agar at 22 ºC, but not
motile in TSB, NB or R2A broth at 22 or 34 ºC. No spores, gas vesicles or other cell
inclusions are present.
Colonies after 2 days incubation at 28 ºC on nutrient agar or R2A agar, are cream,
shiny, translucent, convex 0.5 mm in diameter and becoming slimy with age. Grows at
4 and 34 ºC, but not at 35 ºC, and with 1% NaCl, but not with 2% NaCl. Growth in
mineral medium with glucose or other carbohydrates or acids as substrates depends
on vitamins. Growth on McConkey agar and Columbia-horse blood agar is inhibited;
no single colonies are formed.
Isolated from the gut of the diplopodian Cylindroiulus fulviceps.
Undetermined.

Positive results for catalase, starch hydrolysis (weak), acid production from L-arabinose, dulcitol (weak), D-fructose, D-galactose,
gluconate, D-glucose (without gas production), N-acetylglucosamine, glycerol, D-mannitol, L-rhamnose, D-ribose, and D-tagatose.
Can utilize citrate, mannitol, gluconate, N-acetylglucosamine (weak) and malate (weak).
Negative results for arginine dihydrolase, esculin hydrolysis, DNase, Simmons’ citrate, beta-galactosidase, beta-glucuronidase,
gelatinase, gluconate oxidation, indole production, lysine decarboxylase, malonate oxidation, nitrate reduction, oxidase, ornithine
decarboxylase, tryptophan deaminase, Tween 80 hydrolysis, urease, Voges-Proskauer test, acid production from amygdalin, D-
arabinose, D-arabitol, D-adonitol, arbutin, cellobiose, esculin, inositol, 2- or 5-ketogluconate, lactose, maltose, D-mannose,
melibiose, alpha-methyl-D-glucoside, raffinose, salicin, D-sorbitol, sucrose, trehalose, D-xylose or any other substrate included in API
50 CHE and API 20 E tests.
Does not utilize mannose, maltose or phenylacetate.
H2S is produced from proteose peptone, but not in triple-sugar iron agar slants or in API 20 E strips.
