Abstract

|
To produce ginsenoside-Rg3 enriched edible yeast, ginseng steaming effluent (GSE) was used for yeast cultivation in this study. Four kinds of edible yeasts were cultured in sterilized GSE (2% w/v, pH 6.5), without any nutrient, for 48 h at 30℃, and their growth and ginsenoside compositions were determined. Among the yeasts, Saccharomyces cerevisiae showed the highest growth in the GSE medium. 267.1 ㎎ of Saccharomyces cerevisiae biomass was produced from 1 g of GSE solid and ginsenoside-Rg₃ contents was determined with 0.033 mg. Saccharomyces cerevisiae also showed the best overall acceptability, with a herbal and fermentative flavor and a slightly bitter taste. From these data, we conclude that Saccharomyces cerevisiae is the excellent strain for production of ginsenoside-Rg₃ enriched edible yeast using GSE.
