Example Embodiment
[0021] Example 1
[0022] Add 10g of peptone, 5g of yeast extract, 10g of NaCl and 20g of agar into 1000ml of distilled water, add 2% starch to it, adjust the pH to 7.0, mix well, sterilize at 121°C for 30min, and cool to prepare starch After the starch medium is melted, it is cooled to about 55°C and poured into the flat plate. After the starch medium is solidified, the surface of the starch medium is inoculated with Bacillus species by streaking. Place the plate medium upside down in a constant temperature incubator, incubate at 37±1℃ for 24 hours, turn on the ultraviolet light in the aseptic operation table, sterilize the aseptic operation table for 30 minutes, turn off the ultraviolet light, and place it in the aseptic operation table Scrape the activated and cultivated bacillus strains into a triangular flask containing 100ml sterile water, stir them with a sterile glass rod to make the bacillus strains fully mixed with the sterile water, turn on the ultraviolet light, and a...
