提纯异麦芽低聚糖的酵母菌株筛选及发酵条件

Screening of Yeast Strain for Purifying Isomaltooligosaccharide and Its Fermentation Condition

摘要:

酵母菌同化单糖的能力和速度高于低聚糖,因而可以消除异麦芽低聚糖产品中多余的葡萄糖.通过筛选驯化,得到较快发酵葡萄糖和麦芽糖的D酵母,并对该酵母的最适发酵条件和最佳培养基组成进行了研究,在优化培养基条件下,得到94.13%的高纯度异麦芽低聚糖.

Abstract:

The capacity and speed of yeast to assimilate monosaccharide is bigger than that of yeast to assimilate of oligosaccharide, so the redundant glucose in ismalto-oligosaccharide products can be consumed.A strain D was isolated and screened, which could fast
