| 摘 要： | 从新疆伊犁酸奶子中分离到38株乳杆菌，在不同温度下对其进行生长、产酸性能和蛋白水解能力检测。结果表明许多菌株的生长温度范围比对照菌株嗜酸乳杆菌要宽，不同温度下生长产酸性能和蛋白水解能力都与菌种相关，同时存在较大的菌株间差异。这些乳杆菌菌株生长特性多样，许多菌株性状优良，有广阔的开发应用前景。

| Abstract: | Abilities of growth, acid-production and proteolysis performance of 38 Lactobacillus strains isolated from sour milk in Xinjiang at different temperatures were measured. Some strains could live in a wider temperature range than the control strain of Lb.acidophilus. The abilities of growth and production of acid at different temperatures and proteolysis performance were dependent on the species. Great differences were observed among strains of the same species. Some Lactobacillus strains exhibited excellent growth performance and are potential prospects in the application in dairy products. |
