To produce ginsenoside-Rg3 enriched yeast from ginseng-steaming effluent (GSE), Lipomyces starkeyi, which tends to grow well in GSE, was cultured in sterilized GSE and its growth and production of ginsenoside-Rg3 were determined. Growth of L. starkeyi was 86.1 mg per g GSE and its ginsenoside-Rg3 contents was 0.013 mg per g GSE.
