葡聚糖酶是一种防龋剂,可防止龋斑的形成;在榨糖工业中,它还能用于除去变质的甘蔗汁中的葡聚糖。作者筛选了能稳定产生葡聚糖酶的多种微生物。作者使用小麦麸皮酒曲法和液体培养基沉没培养法筛选了556株真菌和115株链霉菌。酒曲法所用的培养基含有1%葡聚糖 T-2000、33%小麦麸皮、16%黄豆饼粉、50% Dextranase is an anticaries agent that prevents the formation of dental plaque; in the sugar extraction industry it can also be used to remove dextran from deteriorated sugar cane juice. The authors screened a number of microorganisms that produce glucanase stably. The authors screened 556 strains of fungi and 115 strains of Streptomyces using the wheat bran koji method and the liquid medium sunk culture method. The koji medium used contains 1% dextran T-2000, 33% wheat bran, 16% soybean meal, 50%
