| 摘 要： | 试验对酵母发酵的绿茶饮料抗生活性进行了研究。结果表明，采用平板法培养，发酵36小时的绿茶汁对大肠杆菌和金黄色葡萄球菌抑制率分别为98％和100％。液体培养法，发酵48～60小时绿茶汁对乳酸杆菌增生45．1％，对双歧杆菌作用不显著。另外，乙醇、茶多酚与有机酸对大肠杆菌和金黄色葡萄球菌均具有明显抑制作用；茶多酚对乳酸杆菌有一定促生效果。

| Abstract: | The antibiological activities of soft green tea drink fermented by yeast were studied. The inhibition rates of the fermented green tea solution at 36 hours on E. coli and S. aureus were 98% and 100% respectively with plating. The fermented green tea solution between 48 to 60 hours could improve the growth yields of L. bulg 45.1%, only a little action against B.fidobac. Ethanol, catechins and organic acids could significantly inhibit the growth of E. coli and S. aureus . catechins could improve the growth of L. bulg. |
