白酒糟发酵条件的探索和发酵对营养成分的改善

Study on the Fermentation Conditions of Fermented Grains and Fermentation for Nutrient Composition Improvement

在白酒糟发酵时添加枯草芽孢杆菌、酵母菌等微生物制剂,探索其对原料处理、培养基配制、混合菌种组成,发酵时间和发酵温湿度以及通透性等发酵条件和营养成分的改善情况。结果表明,添加微生物制剂使得发酵产品的粗蛋白和真蛋白大幅提升,可代替部分饲料原料用于促进动物的生长,同时形成的有益微生物群能降解白酒糟中的有毒有害物质。

Through adding bacillus subtilis, yeast and other microorganisms in the fermentation distiller to explore the raw material handling, preparing culture medium, composition of mixed culture, improvement for fermentation time and temperature, humidity and permeability and nutrients. The conclusion was as fol- lows： the crude protein and true protein of fermentation products were improved significantly, could replace part of feed raw materials to promote the growth of animal, also degrade the toxic and harmful substances in the fermented grains.
