摘要
通过多点采样 ,多次反复筛选 ,从蔬菜地土壤中筛选出一株具有高絮凝活性的细菌。细菌生长过程中可产生具有絮凝作用的胞外分泌物 ,经实验对内蒙天然碱碱泥具有强絮凝作用。通过对菌株的个体形态特征、菌落形态特征、运动性进行观察 ;同时对其接触酶、氧化酶等生理生化指标进行了测试 ,最终确定为产气肠杆菌 (Enterobacteraerogenes)。该菌株可以利用单糖尤其是葡萄糖产酸 ,并可利用果糖产酸 ,兼性厌氧。
Strain of bacteria which produced substances that could defecate the suspending solution of natural soda, were screened from vegetable field. The characteristics of individual form and the colony form and motility of strain were observed. The contact enzyme, the oxidase and so on of the strain were determined. The strain was identified as Enterobacter aerogenes. The strains could produce acid by using monosaccharide especially glucose. The former was facultative anaerobic.
