Schwanniomyces castellii and Endomycopsis fibuligera Produced extracellular amylase(s) when grown on various carbon sources and at different pH values. Both yeast species showed significant amylase synthesis in the presence of either maltose or soluble starch. On the other substrates tested (glucose, cellobiose, sucrose, trehalose, melezitose, raffinose, ethanol, glycerol) differences were found regarding growth and amylase production. Free glucose in the culture medium apparently inhibited enzyme synthesis. The pH range allowing maximal growth and amylase production was 4.5-6.0 for E. fibuligera and 5.5-7.0 for S. castellii.
卡氏许旺酵母（Schwanniomyces castellii）和扣囊内孢霉（Endomycopsis fibuligera）在不同碳源及不同pH值条件下生长时会产生胞外淀粉酶。这两种酵母在麦芽糖或可溶性淀粉存在的情况下均表现出显著的淀粉酶合成。在测试的其他底物（葡萄糖、纤维二糖、蔗糖、海藻糖、松三糖、棉子糖、乙醇、甘油）中，发现其生长和淀粉酶产生存在差异。培养基中的游离葡萄糖明显抑制酶的合成。扣囊内孢霉允许最大生长和淀粉酶产生的pH范围是4.5 - 6.0，卡氏许旺酵母是5.5 - 7.0。
