Saccharomyces cerevisiae strain suitable for the production of baker's yeast that is osmotic and resistant to weak organic acids, its preparation method and use

摘要

The present invention relates to Saccharomyces cerevisiae strains suitable for the production of baker's yeasts which are osmotolerant and which exhibit intrinsic resistance to weak organic acids. The strains of the present invention are obtained by means of a process of hybridization or of mutation of the industrial S. cerevisiae strain deposited on Jul. 8, 2010 with the CNCM [French National Collection of Microorganism Cultures] under number I-4341, or from an industrial strain related thereto via the Ty profile thereof and/or via quantitative trait locus mapping (QTL mapping).
