| 摘 要： | 采用MaCSPDMDAAC微胶囊对两种乳杆菌进行了固定化发酵研究。结果表明，两种乳杆菌能够在微胶囊内很好地生长和繁殖，菌浓度可分别达到18×1011/mL 胶囊和269×1011/mL胶囊，比游离培养高出十倍以上，并且能与游离发酵一样产生乳酸，糖耗时间可缩短1/3～2/3。进行的多批次发酵显示了巨大的产酸能力。

| Abstract: | The NaCS-PDMDAAC capsules were used to immobilize the two kinds of lactobacillus. The experiment results showed that two kinds of lactobacillus could grow well, and the densities of cells were 1.8 x 10(11)/mL capsule and 2.79 x 10(11)/mL capsule, respectively which was much higher than that in free cell culture. The conversion rate of lactic acid could be 2-5 folds higher than that in free cell culture. |
