【摘要】 从桔汁矿化水饮料中分离到一株编号为9191的革兰氏阴性短杆菌,其形态、生理生化特性与假单胞菌属已报道的种均不相同.该菌株具极生单鞭毛,氧化酶和触酶均阳性;O-F葡萄糖为非发酵型,不产生荧光色素,不产生脓菌素,不产生类胡萝卜色素,对葡萄糖呈碱反应.经类脂粒染色后细胞内可见PHB颗粒积聚.脲酶阳性,硝酸盐还原阳性,反硝化阴性;不水解淀粉和明胶,精氨酸双水解酶阴性;41℃下不生长,在麦康凯和SS平板上不生长.在0.85%CaCl₂的牛肉汤中不生长;利用β-羟基丁酸作为唯一碳源;DNA中G+C含量为65.15mol%.因此定为假单胞菌属中的一个新种.根据其对生理盐水敏感的特性,命名为盐敏假单胞菌（Pseudomonas halosensibilis Zou ＆ Cai nov.sp.）.更多还原

【Abstract】 A strain No. 9191 isolated from fruit juice mineral drink is gram-negetive short-rod. It differs from reported species of Pseudamonas in morphological,physiological and biochemical characteristics. Main characteristics of No. 9191 are single polar flag-elled, oxidase and catalase positive, no acid from glucose but producing alkali,nitrate reduced to nitrite,inability to hydrolize gelatin and starch,arginine dihydrolase absent, no growth in presence of 0. 85% NaCl. The G+C mol% of DNA is 65. 15. It is named Pseudomonas halosensibilis Zou &. Cai nov. sp. by the sensibility property for salt.更多还原
