| 特征特性 |
Cells are Gram-stain-negative, aerobic and motile rods. Colonies are semi-translucent, opalescent, convex and round with clear margins on YMA medium. The optimum temperature for growth is 28 ℃. Growth occurs at 10-45 ℃, pH 6–10 and with 0–2% NaCl (w/v). It is positive for catalase, oxidase, urease, glucose fermentation and nitrate reduction and negative for L-phenylalanine ammonia-lyase and 3-ketolactose production. No growth occurs in nutrient broth. D-arabinose, Dextrin, Fructose, D（+）- galactose, inositol, lactose, Calcium malate, maltose, D-mannitol, melezitose, melibiose, sodium pyruvate, rhamnose, sodium acetate, D- sodium gluconate, sodium succinate, D-sorbitol, sucrose, sodium tartrate, trehalose, xylose, DL-asparagine, L-methionine and L-threonine can be used as sole carbon sources but inulin, starch, glycine cannot. DL-alanine, L-arginine, L-cystine, D-glutamic acid, L-lysine, L-phenylalanine, D-threonine and D-valine can be utilized as sole nitrogen sources but glycine and L- threonine cannot. The main cellular fatty acids are summed feature 8 (C18:1ω 7c and/or C18:1ω 6c), C16:0, C16:0 3-OH. |
