General information
Description and emendation
Gram-reaction-negative coccoid to rod-shaped that are facultatively anaerobic and motile. Cells are 0.9-1.0 µm wide by 1.5-3.0 µm long and occur singly or in pairs. After 24 h aerobic incubation at 37°C on TSA medium, colonies are yellow-pigmented and convex. Catalase-positive and negative or weakly positive for oxidase. After 24 h of aerobic incubation at 37°C on TSA medium, colonies are yellow pigmented and convex. Colonies grow poorly at 10°C (within 3 days), but grow well at 44°C. Positive for the hydrolysis of 5-bromo-3-indoxyl-nonanoate and the utilization of trans-aconitate, 5-keto-D-gluconate, protocatechuate, p-hydroxybenzoate and quinate. Negative result in tests for urease and ornithine decarboxylase, arginine dihydrolase and lysine decarboxylase activities, indole and H2S production and the Voges-Proskauer reaction. Acid is produced from the following compounds: galacturonate, D-mannitol, maltose, D-glucose, L-arabinose and trehalose. No acid production is observed for L-arabitol, 5-ketogluconate, sodium pyruvate, adonitol, palatinose, inositol or D-sorbitol. The chromogenic substrates ONPG, 5-bromo-3-indoxyl-nonanoate, 4-nitrophenyl β-D-glucopyranoside, 4-nitrophenyl β-D-galactopyranoside, 4-nitrophenyl α-D-glucopyranoside, 4-nitrophenyl α-D-galactopyranoside and 4-nitrophenyl α-D-maltopyranoside are hydrolysed. The following compounds are not hydrolysed:4-nitrophenyl β-D-glucuronide and L-aspartic acid 4-nitroanilide. Positive reaction in tests for the utilization of α-D-glucose, β-D-fructose, D-galactose, trehalose, D-mannose, α-melibiose, maltotriose, maltose, α-lactose, 1-O-methyl β-galactopyranoside, 1-O-methyl α-galactopyranoside, cellobiose, β-gentiobiose, 1-O-methyl β-D-glucopyranoside, D-ribose, L-arabinose, D-xylose, α-L-rhamnose, glycerol, D-mannitol, D-saccharate, mucate, L-malate, cis-aconitate, trans-aconitate, D-glucuronate, D-galacturonate, 2-keto-D-gluconate, 5-keto-D-gluconate, N-acetyl-D-glucosamine, D-gluconate, protocatechuate, p-hydroxybenzoate, quinate, putrescine, DL-α-amino-N-butyrate, DL-lactate, D-glucosamine, L-aspartate, L-glutamate, L-proline, L-alanine and L-serine. The following compounds are not utilized as sole sources of carbon: L-sorbose, α-L-fucose, L-arabitol, xylitol, D-tagatose, myo-inositol, maltitol, D-sorbitol, adonitol, hydroxyquinoline-β glucuronide, i-erythritol, 3-O-methyl D-glucopyranose, D-tartrate, myo-tartrate, tricarballylate, L-tryptophan, phenylacetate, gentisate, m-hydroxybenzoate, benzoate, 3-phenylpropionate, trigonelline, betain, histamine, caprate, caprylate, L-histidine, glutarate, DL-α-amino-N-valerate, ethanolamine, tryptamine, itaconate, DL-β-hydroxybutyrate, malonate, propionate, L-tyrosine or 2-oxoglutarate.
