Aspergillus oryzae resistant to high temperature and high in yield of acid protease and application of aspergillus oryzae in solid state fermentation

The invention discloses a high-temperature-resistant and high-yield acid protease aspergillus candidus and application of the high-temperature-resistant and high-yield acid protease aspergillus candidus in solid-state fermentation, aspergillus candidus M047 is obtained by separating and purifying yeast for making hard liquor and is preserved in the China Center for Type Culture Collection (CCTCC) on January 10, 2022, and the preservation number is CCTCC NO: M2022054. The invention further discloses a preparation method of the high-temperature-resistant and high-yield acid protease aspergillus candidus and application of the high-temperature-resistant and high-yield acid protease aspergillus candidus to the solid-state fermentation of the high-temperature-resistant and high-yield acid protease aspergillus candidus. When the aspergillus candidus is used for preparing a solid-state bacterial preparation and used for a solid-state fermentation process, the utilization rate of protein in solid-state fermentation c
