摘　　要：分析液芯胶囊组分中的氯化钙、黄原胶含量以及液芯胶囊碎片和利用液芯胶囊固定化培养对保加利亚乳杆菌生长的影响,探讨液芯胶囊对保加利亚乳杆菌生长的影响。在MRS培养基中添加不同浓度的氯化钙、黄原胶和液芯微胶囊碎片培养保加利亚乳杆菌,并用液芯生物微胶囊进行固定化培养保加利亚乳杆菌。结果显示:黄原胶对保加利亚乳杆菌的生长基本没有影响;高浓度的CaCl2对保加利亚乳杆菌的生长有明显的抑制作用,并且随浓度的增高抑制作用越发明显,甚至产生毒害作用。液芯微胶囊碎片以及液芯微胶囊对保加利亚乳杆菌均显示了良好的生物相容性。表明其作为整个体系来说,具有良好的生物相容性,该微胶囊可用于微生物细胞的固定化培养。The effects of CaC12 and xanthan gum with different concentrations and the fragment of liquid-core encapsulation on the growth of free Lactobacillus bulgaricus were studied respectively. The effects of liquid-core encapsulation material on the growth of Lactobacillus bulgaricus were discussed. The medium MRS with different concentrations of CaCl2, xanthan gum and the fragment of liquid-core encapsulation were used to culture Lactobacillus bulgaricus. The immobilization of LactobaciUus bulgaricus using liquid-core encapsulation was also studied. Xanthan gum did not exhibit any effects on the growth of Lactobacillus bulgaricus, and the fragment of liquid-core encapsulation barely showed the effects on the growth of Lactobacillus bulgaricus. However, the high concentration of CaCl2 strongly inhibited the growth of LactobaciUus bulgaricus. Taken togther, the liquid-core encapsulation had a desirable biocompatiability and could be used as a new immobilization system.
