摘要
以粮食加工副产物为原料，经多菌种混合固态发酵后制备了高酶活的饲用复合酶制剂。培养基配比为麦麸豆粕米糠＝ ２７１。３０ ℃培养４６ ｈ 后， 每克干物质中含有糖化酶２ ０５０ Ｕ， 纤维素酶３ ７６０ Ｕ，蛋白酶７ ３４０ Ｕ，果胶酶３３１ Ｕ。
Feed multienzyme preparation from byproducts of grainprocessing by mixed-culture solid state fermentation was reported. The ratio of wheat bran: beancake: rice bran in the culture medium was 271. After culturing at 30 ℃ for 46 hours, one gram of dried medium contained glucoamylase 2 050 U, cellulase 3 760 U, proteinase 7 340 U,pectate lyase 331 U.
