Abstract: The present invention discloses a strain of ammonium sulfate-tolerant Saccharomyces cerevisiae, and a screening method thereof. The strain of ammonium sulfate-tolerant Saccharomyces cerevisiae, named Saccharomyces cerevisiae Z-1, was preserved in Guangdong Microbial Culture Collection Center on Mar. 3, 2023, with a preservation number of GDMCC NO: 63227 and a preservation address of Floor 5, Building 59, No. 100 Courtyard, Xianlie Middle Road, Guangzhou. The ammonium sulfate-tolerant Saccharomyces cerevisiae Z-1 provided by the present invention may grow and breed in an environment containing 1.0 mol/L NH4+ (6.6% ammonium sulfate), and the protein content of the strain can reach 51.97%; and as a fermentation strain for protein feed, the strain of the present invention not only can adapt to the high-tolerance environment, but also can increase the protein content of the protein feed, and is an excellent strain for solid-state fermentation.
