材料和方法酶。分别用霍华德（1959）和AbouAkkada &霍华德（1960）的方法制备了反刍毛癣菌和尾甲沟虫的透析和冷冻干燥提取物。冷冻干燥的粉末各自含有约9%的N。D.除了麦芽糖酶外，反刍动物还含有淀粉酶、转化酶、纤维二糖酶、β-葡糖苷酶和果胶酶（Mould和托马斯，1958;霍华德，1959; Abou Akkada和霍华德，1961）。内甲藻的提取物除麦芽糖酶外还含有淀粉酶、蛋白酶和肽酶（Abou Akkada &霍华德，1960，1962）。
MATERIALS AND METHODSEnzymes. The dialysed and freeze-dried extracts of Dasytricha ruminantium and Entodinium caudatum were prepared by the methods of Howard (1959) and AbouAkkada & Howard (1960) respectively. The freeze-dried powders each contained about 9% of N. The extracts of D. ruminantium contained amylase, invertase, cellobiase, f,-glucosidase and pectinase in addition to maltase (Mould & Thomas, 1958; Howard, 1959; Abou Akkada & Howard, 1961). The extracts of entodinia contained amylase, proteinase and peptidase in addition to maltase (Abou Akkada & Howard, 1960, 1962).
