Novel saccharomycopsis fibuligera fortified yeast and application thereof in improving wine quality

The invention relates to the technical field of microorganisms, in particular to novel saccharomycopsis fibuligera fortified yeast and application thereof to improvement of wine quality, self-screened saccharomycopsis fibuligera S1 is researched, aiming at the problem of low wine yield of saccharomycopsis fibuligera, saccharomyces cerevisiae is combined for compounding, and the proportion of main strains is optimized, so that the saccharomycopsis fibuligera fortified yeast is obtained. A plurality of formulas are stored to cope with different seasonal changes, so that the quality and yield balance of the raw wine is guaranteed; through verification, the screened saccharomycopsis fibuligera S1 is compounded with kluyveromyces marxianus Y245 and rhizopus G1 to prepare the distiller's yeast, so that the wine yield of the rice-flavor distiller's yeast can be remarkably improved, meanwhile, the ester content and types of rice-flavor raw wine are improved, the taste of the rice-flavor raw wine is effectively enrich
