Interaction between Lactobacillus acidophilus and Saccharomyces uvarum on Utilization of Galacto-oligosaccharides in Soymilk
Lactobacillus acidophilus와 Saccharomyces uvarum의 혼합배양에 의한 두유의 발효 중 당이용에 미치는 작용
Abstract
The enhanced growth and lactic fermentation of L. acidophilus, when mixed with S. uvarum, was investigated. Spent medium of S. uvarum, at 10%, stimulated the growth and lactic fermentation of L. acidophilus, and also increased the content of monosaccharide while decreased the contents of sucrose, raffinose, and stachyose in soymilk. While single culture of L. acidophilus consumed only the monosaccharides in soymilk, the mixed culture of L. acidophilus and S. uvarum consumed almost all the oligosaccharides as well as the monosaccharides in soymilk. Thus it was assumed that S. uvarum converted the oligosaccharides into monosaccharides so that L. acidophilus can produce more lactic acid and cell mass by using the increased monosaccharides.
