description
Cells are Gram-negative rods (1.5 – 3 X 0.4 – 0.5 µm) with an irregular fibril structure and are motile and strictly aerobic. Catalase-positive and oxidase-negative. Colonies are pink, circular and convex with regular margins. Flexirubin is detected. Growth occurs at 4 – 37 ° C (optimum 30 ° C), at pH 7 – 10 (optimum pH 8) and at NaCl concentrations of up to 3.0 % (optimum 2.0 %). Positive for hydrolysis of aesculin, casein, starch and gelatin. In API ZYM tests, positive for alkaline phosphatase, esterase (C 4), esterase lipase (C 8), leucine arylamidase, valine arylamidase, naphthol-AS-BI-phosphohydrolase, OE - galactosidase, N - acetyl- β - glucosaminidase and OE - glucosidase, but negative for lipase (C 14), cystine arylamidase, trypsin, OE - chymotrypsin, acid phosphatase, β - galactosidase, β - glucuronidase, β - glucosidase, OE - mannosidase and OE - fucosidase. In API 20 NE test strips, positive reactions are observed for nitrate reduction, aesculin hydrolysis, gelatin hydrolysis and β - galactosidase (weak) and negative reactions are observed for arginine dihydrolase, indole production, urease and glucose fermentation. Does not assimilate D- glucose, L- arabinose, maltose, D- mannose, D- mannitol, N - acetylglucosamine, adipic acid, capric acid, malic acid, potassium gluconate, trisodium citrate or phenylacetic acid. In API 20 E tests, shows positive reactions for β - galactosidase (weak), tryptophan deaminase and gelatin hydrolysis, weakly positive reactions for oxidation of sucrose, melibiose, amygdalin and arabinose and negative reactions for arginine dihydrolase, lysine decarboxylase, ornithine decarboxylase, citrate utilization, H 2 S production, Voges – Proskauer reaction, urease, indole production and oxidation of glucose, mannitol, inositol, sorbitol and rhamnose. Susceptible to (per disc) erythromycin (15 µg), vancomycin (30 µg), acheomycin (30 µg) and penicillin (10 IU). The major quinone is MK- 7. The DNA G + C content of the type strain is 47.1 mol %.
