化学 右旋糖酐酶 The highest yield of 86.8% was attained by adding two enzymes simultaneously. For dextran synthesis,in 100 mL 10% sucrose solution adding 15 U dextransucrase together with 0.19～0.75 U dextranase,the resulting relative molecular mass of dextran was 1.0×105～2.0×104. 在100 mL蔗糖质量浓度为100 g/L的底物溶液中,加入15 U右旋糖酐蔗糖酶液,同时加入0.19~0.75 U右旋糖酐酶,反应24 h,可以得到相对分子质量为1.0×105~2.0×104的右旋糖酐。 葡聚糖酶
