| Abstract: | 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. |
