- W209883962 abstract "摘要以实验室制备的酵母（1→3）-β-D-葡聚糖为原料，通过酶解法制备水溶性酵母（1→3）-β-D-葡聚糖，并对其结构和生物活性进行了研究。以水溶性酵母葡聚糖得率为指标，通过单因素和正交实验，确定了酵母（1→3）-β-D-葡聚糖酶解的S-艺条件。优化后的酶解条件为：酶活浓度0．15U／mL，底物质量浓度0．5g／100mL，酶解温度40℃，pH3．5，酶解时间0．5h，该酶解条件下水溶性酵母葡聚糖得率为80．3％。红外光谱分析表明，水溶性葡聚糖仍具有（1→3）-β-D-葡聚糖分子构型，刚果红实验表明其具有三螺旋结构。活性实验表明，水溶性葡聚糖能有效提高E．coli诱导的患腹膜炎小鼠的存活率。" @default.
