Siccibacter Stephan et al. 2014
General information
Description and emendation
Cells are 1.0 µm wide and 1.5-2.5 µm long Gram-reaction-negative peritrichously flagellated, coccoid to rod-shaped and occur singly or in pairs. They are weakly oxidase-positive, catalase-positive and facultatively anaerobic. After 24 h of aerobic incubation at 37°C on TSA medium, colonies are yellow-pigmented and convex. Colonies grow well at 10°C (within 3 days) but poorly at 44°C. Positive for malonate and negative for urease, arginine dihydrolase and ornithine and lysine decarboxylase. Tests for indole and H2S production and the Voges-Proskauer reaction are negative. Acid is produced from the following compounds: galacturonate, D-mannitol, maltose, D-glucose, L-arabinose, trehalose and L-rhamnose. No acid production is observed from L-arabitol, D-arabitol, 5-ketogluconate, sodium pyruvate, adonitol, palatinose, sucrose, inositol, cellobiose or D-sorbitol. The chromogenic substrates ONPG, 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:5-bromo-3-indoxyl-nonanoate, 4-nitrophenyl β-D-glucuronide, palatinose 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, aesculin, D-ribose, L-arabinose, D-xylose, α-L-rhamnose, dulcitol, glycerol, D-mannitol, turanose, D-saccharate, mucate, L-malate, cis-aconitate, D-glucuronate, D-galacturonate, 2-keto-D-gluconate, N-acetyl-D-glucosamine, D-gluconate, 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, sucrose, raffinose, lactulose, α-L-fucose, D-arabitol, L-arabitol, xylitol, D-tagatose, myo-inositol, maltitol, D-sorbitol, adonitol, hydroxyquinoline-β-glucuronide, i-erythritol, 1-O-methyl α-D-glucopyranoside, 3-O-methyl D-glucopyranose, L-tartrate, D-tartrate, myo-tartrate, trans-aconitate, tricarballylate, 5-keto-D-gluconate, L-tryptophan, phenylacetate, protocatechuate, p-hydroxybenzoate, quinate, gentisate, m-hydroxybenzoate, benzoate, 3-phenylpropionate, trigonelline, betain, putrescine, DL-amino-N-butyrate, histamine, caprate, caprylate, L-histidine, fumarate, glutarate, DL-glycerate, DL-α-amino-N-valerate, ethanolamine, tryptamine, itaconate, DL-β-hydroxybutyrate, malonate, propionate, L-tyrosine or 2-oxoglutarate.
