摘要: 以蔗糖、甘露醇、山梨醇、麦芽糖、谷氨酸钠为保护剂对筛自泡菜的嗜酸乳杆菌S1的冻干保护效果进行研究表明,乳糖为最佳保护剂,菌体存活率可达到了70%以上,其次是麦芽糖、山梨醇、蔗糖、甘露醇。对冻干前后及未加保护剂的菌体作电镜观察表明,所选保护剂对菌体有很好的保护作用。

Abstract: Experiments of Freeze-dried protection on S1(Lactobacillus acidophilus) isolated from the Chinese Sauerkraut juice with sucrose, lactose, mannitol , sorbitol, maltose, and sodium glutamate as pretectants, showed that the best protection agent is lactose. The S1 survival rate is more than 70%, secondly is maltose, sorbitol, sucrose and mannitol. The electron microcopis observations showed that the protection agent chosen has good protection function on the bacteria.
