Production of Active Dry Yeast by Using Corn Steep Liquid

Zhong Zhen-sheng

Abstract

Com steep liquor was used as fermentation raw materialfor production of active dry yeast by fermentation.exploring and optimize the fermentation conditions.The results showed that the best fermentation conditions were corn steep liquor in culture medium 14.00%,pH 5.5,initial glucose 200mg/ml,inoculum size 1.2% ferment time 46 hours,under which the dry yeast could reached the highest yield of 17.00mg/ml,and cell survival rate was 96.40%.
