乳酸菌冻干保护剂及保护机理的研究进展

The Research Development of Cryoprotector of Lactic Acid Bacteria and its Protective Mechanism

乳酸菌细胞在冻干过程中要受冷冻和干燥两种因素的作用,采取适宜的保护措施,在很大程度上可减轻或避免冷冻干燥对细胞带来的损伤。本文对乳酸菌冻干保护剂及保护作用的机理进行了阐述。

Lactic acid bacteria were intensely affected by freezing and drying when being lyophilized. Damages was strongly alleviated and avoided by suitable protective measures when cell underwent freeze-drying. Protective material and fixed material played a fairly role in protecting. This thesis discussed Lactic acid bacteria freeze-drying protective material and the protective mechanism.
