【摘要】 以卡拉胶为材料对乳酸乳球菌Y-72进行了固定化分批发酵和连续发酵的研究，测定了2种情况下发酵液效价、细胞游离数等参数。固定化分批发酵效价达到1 420 IU／mL，但发酵伴随着细胞的大量游离，在固定化连续发酵时则克服了这一缺点，该发酵连续运行144 h未见发酵液效价下降，发酵液效价稳定在600～800 IU／mL之间。更多还原

【Abstract】 ：In this study,immobilized batch and continuous fermentation was carried out with Lactoccus lactis subsp.Lactis Y-72 which was immobilized by κ-carrageenan.In these two conditions many parameters were detected.It was founded that,in the immobilized batch process,the nisin activity can reach to 1 420 IU／mL，but with many cells released.In the continuous fermentation,this defect was avoided and this fermentation was performed for 144 h without the decrease of activity,the activity is between 600 and 800 IU／mL.更多还原
