General information
Description and emendation
Straight rods, 0.5-0.7 µm wide and 1.8-2 µm long. Non-encapsulated. Non-spore-forming. Non-motile. Non-haemolytic. Produces lemon yellow colonies. Gram-stain-negative. Growth is facultatively anaerobic and occurs at 4-30°C. No growth is observed at 37°C (21 day). Growth occurs with 0-7% NaCl (optimum, 0.5% NaCl). Oxidase-negative. Ferments glucose. Positive result in Voges-Proskauer and Simmons citrate tests. Nitrate is not reduced to nitrite, and H2S and indole are not produced. Aesculin is hydrolysed, but gelatin and urea are not. Negative result in arginine dihydrolase, lysine and ornithine decarboxylase tests. In API50 CH strips, after 48 h, acid is produced from L-arabinose, D-glucose, myo-inositol, D-mannitol, D-mannose, melibiose, L-rhamnose, salicin and D-xylose; acid is not produced from D-arabitol, cellobiose, lactose, maltose, methyl α-D-glucoside, raffinose, D-sorbitol, sucrose, trehalose, glycerol, D-adonitol and dulcitol. The DNA G+C content of the type species is 53 mol%.
1: Produces whitish or lemon-yellow colonies. Growth is facultatively anaerobic and occurs at 4-30°C. Some species fail to grow at 37°C (21 days). Some species fail to reduce nitrate to nitrite. Acid is produced after 48 h from L-arabinose, cellobiose, D-glucose, myo-inositol, lactose, D-mannitol, D-mannose, melibiose, salicin and D-xylose; acid is not produced from D-adonitol, dulcitol and D-sorbitol.
