Embodiment 1
[0058] 1. Selection of fermentation strains and preparation of medium
[0059] Bacteria A—Bacillus subtilis CICC10063, Bacillus subtilis.
[0060] The culture medium is: 0.5 grams of sodium chloride, 1 gram of beef extract, 1 gram of peptone, and 100 milliliters of water with a pH of 7.2.
[0061] Bacteria - beer yeast CICC 31362, Saccharomyces cerevisiae.
[0062] Medium: 5 ° Bé wort.
[0063] 2. Preparation process of fermentation strain
[0064] 2.1 Activation of freeze-dried bacteria powder
[0065]Measure 10ml of 0.9% normal saline into 2 test tubes, sterilize at 121°C for 20 minutes and cool to 30°C, pour all the freeze-dried bacteria powders in the ampoules of 2 strains into 0.9% In normal saline, oscillate to make it dissolve, and activate it in a 30°C incubator for 30 minutes, and set aside.
[0066] 2.2 Expanded cultivation of fermentation strains
[0067] 2.2.1 Preparation of primary fermented seeds
[0068] Measure 200ml of the culture medium of 2 strains of...
