摘要

Abstract

Out of the eight malt types tested, Danpi-2 barley showed the highest concentration of toxic crude protein with 338μg/g of crude protein,which extracted from malt by sulphuric acid and fractionated by ammonium sulphate precipitation.The character analysis of anti- yeast protein also showed that 10kDa protein tolered temperature as high as 100℃.Adding anti- yeast crude protein into fermentation liquor, the yeast amount decreased remarkably, utilization of glucose decreased and pH decreased slowly.When the concentration of proteins was increased to 32μg/mL,the inhibition ratio also went up by 50%.
