  • Ethanol resistance GP-01 by protoplast fusion, method for manufacturing thereof, method for manufacturing yeast containing high content of bio organic germanium by using GP-01 and high water soluble sodium metagermanate as a germanium source
    Patent number: 8569039
    Abstract: A biologically pure culture of Saccharomyces cervisiae GP-01, and a method for producing Saccharomyces Cervisiae GP-01 which is ethanol-resistant and obtained by protoplast fusing Saccharomyces Cerevisiae (KCTC 7904) and Candida Ethanolica (KCTC 7181). Further, the present invention provides yeast containing the high content of organic bio-germanium (the yeast Ge-32K) and a method for producing the yeast Ge-32K, comprising adding the yeast GP-01 into a solution of sodium metagermanate (Na2GeO3) at the volume ratio of 1:0.5˜2; adding 0.1˜0.4 wt % of surfactant, instead of germanium dioxide as used in the prior arts; and cultivating an obtained broth. The obtained yeast Ge-32K contains the higher content of the organic bio-germanium than the conventional yeast as produced by using germanium dioxide.
