General information
Description and emendation
Cells are Gram-negative, non-motile, non-spore-forming rods (0.5 × 1.0-2.5 μm). Good growth is observed on TSA and nutrient agar at 28-37°C, but no growth is observed at 5 or 42°C. Colonies are white-yellow, non-pigmented, semi-translucent, circular and shiny with entire edges. Catalase, oxidase, phosphatase and β-galactosidase activities are positive. H2S is not produced. Casein, aesculin and gelatin are hydrolysed, but starch is not. Malonate is not utilized. Nitrate is not reduced. Acid is produced from D-fructose, D-glucose, lactose, D-maltose, D-mannitol and trehalose, but not from L-arabinose, D-cellobiose, raffinose, sucrose, salicin or D-xylose. As determined with the API ZYM system, the following substrates are hydrolysed:2-naphthyl phosphate (pH 8.5), 2-naphthyl caprylate, L-leucyl-2-naphthylamide, L-valyl-2-naphthylamide, N-benzoyl-DL-arginine-2-naphthylamide, 2-naphthyl phosphate (pH 5.4), naphthol-AS-BI-phosphate, 2-naphthyl α-D-glucopyranoside and 1-naphthyl-n-acetyl-β-D-glucosaminide, but the following substrates are not hydrolysed:2-naphthyl myristate, naphthol-AS-BI-β-D-glucuronide, 6-bromo-2-naphthyl-β-D-glucopyranoside and 6-bromo-2-naphthyl-α-D-mannopyranoside. The fatty acid profile consists largely of 15:0 iso, 17:0 iso 3-OH and summed feature 4 (15:0 iso 2-OH and/or 16:1 ω7c/t). Menaquinone MK-6 is the predominant quinone. The G+C content of the DNA is 35.0-38.2 mol%.
1: Cells are Gram-negative, non-motile, non-spore-forming rods (0.5 × 1.0-2.5 μm). Good growth is observed on TSA and nutrient agar at 28-37 °C, but no growth is observed at 5 or 42 °C. Colonies are white or yellow, semi-translucent, circular and shiny with entire edges. Catalase, phosphatase and β-galactosidase activities are positive. Indole is produced. Casein is hydrolysed, but starch is not. Malonate is not utilized. Acid is not produced from galactose, melezitose, raffinose, adonitol, dulcitol, sorbitol, or inositol, or salicin. The fatty acid profile consists largely of iso-C15:0, iso-C17:0 3-OH and summed feature 4 (iso-C15:0 2-OH and/or C16:1 ω7c/t). Menaquinone MK-6 is the predominant quinone. The G+C content of the DNA is 35.0-38.2 mol%.
2: Cells are Gram-negative, non-motile, non-spore-forming rods (0.5 × 1.0–2.5 μm). Good growth is observed on TSA and nutrient agar at 28–37 °C, but no growth is observed at 5 or 42 °C. Colonies are white or yellow, semi-translucent, circular and shiny with entire edges. Catalase, phosphatase and β-galactosidase activities are positive. Indole is produced. Casein is hydrolysed, but starch is not. Malonate is not utilized. Acid is not produced from galactose, melezitose, raffinose, adonitol, dulcitol, sorbitol, or inositol, or salicin. The fatty acid profile consists largely of C15:0 iso, C17:0 iso 3-OH and summed feature 4 (C15:0 iso 2-OH and/or C16:1 ω7 c/t). Menaquinone MK-6 is the predominant quinone. The G+C content of the DNA is 35.0–38.2 mol%.
