| 摘 要： | 通过平板计数法测定脱脂乳为培养基的发酵液中乳酸菌的活菌数,并测其对应的吸光度,研究两者之间的相关关系。结果表明:在发酵过程中以脱脂乳为培养基的发酵液中乳酸菌的活菌数与吸光度之间呈线性相关关系。因此,通过测定发酵液的吸光度可以评定发酵乳制品中乳酸菌的活菌数。 |
| 关 键 词： | 脱脂乳 乳酸菌 活菌数 吸光度 |

| Abstract: | This test studied on relations between viable bacteria counts and corresponding absorbency of fermented liquid using skim milk as culture medium.The result showed that the relation between viable bacteria counts and its absorbency is linear correlation while taking skim milk as culture medium in the fermented course.So we can infer viable bacteria counts in the fermented dairy products through determining its absorbency in the fermented course. |
| Keywords: | skim milk lactobacillus viable bacteria counts absorbency |
