The invention discloses saccharomyces cerevisiae engineering bacteria with high yield of mannan as well as a construction method and application of the saccharomyces cerevisiae engineering bacteria, and belongs to the technical field of brewing microorganisms. The saccharomyces cerevisiae engineering bacterium is obtained by modifying saccharomyces cerevisiae BY4741 serving as a chassis strain by utilizing a CRISPR / Cas9 gene editing technology, firstly, genes SMI1 and FKS1 for controlling synthesis of beta-1, 3 glucan are knocked out from the saccharomyces cerevisiae BY4741, a polyterpenyl phosphate-beta-glycosyl transferase gene ALG5 is subjected to free overexpression, and the final mannan yield reaches 283.16 mg / L (28.316 mg / g thallus dry weight). Alpha-1, 2-mannosyl transferase MNN2 is knocked out on the basis of the strain to obtain saccharomyces cerevisiae engineering bacteria, and the saccharomyces cerevisiae engineering bacteria are fermented, cultured, extracted, separated and purified to obtain high-purity mannoglycoprotein without N-glycosylated branched chains. The wine has the effects of remarkably reducing the astringent taste of the wine, improving the roundness of a wine body, improving tartrate precipitation and the like, so that the overall quality of the wine is improved.
