摘　　要：对分离自内蒙古自治区浑善达克盐碱湖的一株杆菌菌株MIM18的培养特征进行了研究。结果表明,该菌为革兰氏阳性杆菌,粉红色,分泌过氧化氢酶、精氨酸双水解酶和赖氨酸脱羧酶,对常见的抗生素高度敏感。生长盐浓度为0～55 g/L,最适盐浓度为10 g/L;温度范围24～40℃,最适温度33℃;pH 6.0～11.0,最适pH 9.5。好氧,属于兼性嗜碱菌。The cultural characteristics of a strain,MIM18,isolated from the Hunshandake salt alkaline lake in Inner Mongolia were investigated.The results showed that the strain was found to be a gram-positive,rods and pink-pigmented bacterium,secreted catalase,arginine dihydrolase and lysine decarboxylase,was sensitive to common antibiotics.The strain was able to grow in 0～55 g/L total salts and the optimal concentration was 10 g/L.The range of temperature for this strain was 24～40 ℃ and the optimal temperature was 33 ℃.The range of pH was 6.0～11.0 and the optimal pH was 9.5.This strain was aerobe and facultative alkalophile.
