[0017] First take 1kg of coral and clean it with deionized water, then add it to the container, then add 600mL of 5% hydrogen peroxide solution, heat the container to 40°C, soak for 1 hour, stop heating, and take out the coral. Put it in a ventilated place to dry naturally for 5 hours, put the dried coral into a pulverizer and crush it for 30 minutes, collect the broken coral, and set aside; weigh 10g glucose, 5g peptone, 0.8g sodium chloride, 0.3g dipotassium hydrogen sulfate and 5g of peanut powder were added to a beaker, stirred and mixed for 1min, placed in a sterilized tank, and sterilized at 95°C for 5min, after the sterilization was completed, the temperature was naturally lowered to 30°C to obtain fermented nutrients; the above fermented nutrient The material and 20g of spare broken coral were added to the fermenter, and Bacillus subtilis was inoculated into the fermenter according to the inoculation amount of 8%, and it was aerobically fermented at 30°C for 3 days.

[0020] First take 1kg of coral and clean it with deionized water, then add it to the container, then add 650mL of 5% hydrogen peroxide solution, heat the container to 45°C, soak for 1 hour, stop heating, and take out the coral. Put it in a ventilated place to dry naturally for 5 hours, put the dried coral into a pulverizer and crush it for 35 minutes, collect the broken coral, and set aside; weigh 15g glucose, 6g peptone, 0.9g sodium chloride, 0.4g dipotassium hydrogen sulfate and 6g of peanut powder were added to a beaker, stirred and mixed for 2 minutes, placed in a sterilized tank, and sterilized at 100°C for 8 minutes. After the sterilization was completed, the temperature was naturally lowered to 35°C to obtain fermented nutrients; The material and 25g of spare broken corals were added to the fermenter, and then Bacillus subtilis was inoculated into the fermenter according to the inoculation amount of 9%, and aerobic fermentation was carried out at 35°C for 3 days. After t...

[0023]First take 2kg of coral and clean it with deionized water, then add it to the container, then add 700mL of 5% hydrogen peroxide solution, heat the container to 50°C, soak for 2 hours, stop heating, and take out the coral. Put it in a ventilated place to dry naturally for 6 hours, put the dried coral into a grinder and crush it for 40 minutes, collect the crushed coral, and set aside; weigh 20g glucose, 8g peptone, 1.0g sodium chloride, 0.5g dipotassium hydrogen sulfate and 8g of peanut powder were added to a beaker, stirred and mixed for 3 minutes, placed in a sterilization tank, and sterilized at 105°C for 10 minutes. After the sterilization was completed, the temperature was naturally lowered to 40°C to obtain fermented nutrients; Add the material and 30g of spare broken coral into the fermenter, then inoculate Bacillus subtilis into the fermenter according to 10% inoculation amount, and ferment aerobically at 40°C for one day. After the fermentation is over, collect th...
