General information
Description and emendation
For members of this genus, cells are facultatively anaerobic, Gram-negative rods and all members of the genus are motile. Typically members of this genus are not producers of the yellow pigment characteristic of Pantoea and can grow at 44 °C. All members are oxidase-negative and catalase-positive. Most members are positive for the Voges-Proskauer reaction (production of acetoin) and hydrolyse aesculin but are negative for the production of arginine dihydrolase, ornithine decarboxylase, lysine decarboxylase, indole and urease. All are negative for the production of H2S and positive for the presence of β-galactosidase. All members utilize the following carbon sources after 48 h: D-glucose, L-arabinose, D-ribose, D-xylose, D-fructose, D-mannose, L-rhamnose, cellobiose, D-galactose, maltose, melibiose, trehalose, glycerol, inositol, D-mannitol, N-acetyl-D-glucosamine, gentiobiose, arbutin and aesculin. Variable results are obtained for lactose, sucrose, D-sorbitol, raffinose and salicin. The following carbon sources are not utilized by strains tested previously: L-sorbose, melezitose, erythritol, adonitol, dulcitol, glycogen, xylitol, starch, inulin, L-xylose, turanose, lyxose, tagatose, L-arabitol, L-fucose and D-malate. As inferred from genome comparisons, all members of the genus possess the following genes: araA, araB, bcsA, DAK, garR, glgA, glgB, hutG, hutH, hutI, hutU, ipdC, kdgK, MDH, menA, menB, mdoB, nadA, nadB, otsB, phoA/B, puuD, rspB, speG, thiF, thiH, treZ, ulaC, uxaA, uxaE, uxuA, uxuB, XDH, xfp, xylA and yicI. Additionally, 46 hypothetical genes are present in all members of the genus.
