| 摘 要： | 乳酸菌发酵剂应具有高活力、耐贮藏性以及对不同环境的适应性,特别是在冷冻干燥过程中活性的保持。本文从乳酸菌发酵剂菌种的内在特性、培养时间、培养基成分、培养温度及pH值的变化等方面综述了不同培养条件对乳酸菌发酵剂抗冷冻干燥性能影响的研究进展。说明乳酸菌在冷冻干燥中的存活率依赖于它的内在基因,基因差别决定了不同的乳酸菌对冷冻干燥的抗性存在差异;同时与细胞膜成分以及菌株形态有一定的关联;通常生长在稳定期的乳酸菌其抗冷冻干燥能力较强;培养基成分对菌株的影响因菌株不同而异;较低的培养温度和pH值,有助于提高乳酸菌的抗冷冻干燥性能。本文为提高乳酸菌的冻干存活率提供一些参考。

| Abstract: | High viability, storability and tolerance to variable environmental conditions, especially to freeze-drying, are
key factors in the development of lactic acid bacteria (LAB) starter cultures. The effects of diverse growth conditions on
the survival of LAB during subsequent freeze-drying are reviewed in this article, including intrinsic factors of strains,
culture time, medium components, and changes in temperature and pH. This review illustrates that the survival of lactic acid
bacteria during freeze-drying depends on its inherent genes, and genetic differences determine different resistance of lactic
acid bacteria to freeze-drying. At the same time, the survival of lactic acid bacteria is associated with components of the cell
membrane and the bacterial morphology. Lactic acid bacteria usually have stronger tolerance to freeze-drying when they
are cultured in the stable phase. Medium components have different influences on different LAB strains. The lower culture
temperature and pH helps improve the tolerance of lactic acid bacteria to freeze-drying. This paper may provide a reference
for improving the survival ability of LAB during freeze-drying. |
