中文摘要: 该文在考察不同温度对人源乳酸菌菌体生长、胞外多糖浓度及α-葡萄糖苷酶抑制率影响的基础上，采取分阶段控制温度策略对α-葡萄糖苷酶抑制活性进行优化。结果表明，当第一阶段温度37 ℃，变温时间50 h，第二阶段温度40 ℃发酵66 h 时α-葡萄糖苷酶抑制率为58.21%。
Abstract:On the basis of investigating the effects of different temperatures on the growth of human lactic acid bacteria，the concentration of extracellular polysaccharides and the inhibition rate of α -gluconidase，the inhibition activity of α-gluconidase was optimized by a phased temperature control strategy.The results showed that the inhibition rate of α-glucosinase was 58.21 % when the first stage temperature was 37 ℃ ，the temperature was 50 h，and the second stage temperature was 40 ℃ when the fermentation time was 66 h.
