Embodiment 1
[0039] A preparation method of a spore preparation of bacillus coagulans, comprising:
[0040] 1. Bacillus coagulans primary tube slant seeds
[0041] The original bacteria were inoculated on the primary slant medium, and cultured at 30°C-45°C for 20-32h.
[0042] The primary slant medium is a mixed solution (g / L) prepared according to the following ratio: yeast extract 5-15g / L peptone 5-15g / L glucose 0.5-5g / L sodium chloride 5-10g / L phosphoric acid Dipotassium hydrogen 1~5g / L manganese sulfate 0.1~2g / LpH7.0~7.2.
[0043] 2. Bacillus coagulans secondary liquid seeds
[0044] Inoculate the single colony of the primary Bacillus coagulans in step 1 into the secondary culture medium, the liquid volume is 50-100mL / 500mL, and cultivate it under the conditions of 30°C-45°C and 160-300rpm / min for 20-32h to obtain the secondary culture medium Bacillus coagulans seed solution.
[0045] The secondary liquid medium is a mixed solution (g / L) prepared according to the following ratio: g...

[0056] The primary slant medium is a mixed solution (g / L) prepared according to the following ratio: yeast extract 5-15g / L peptone 5-15g / L glucose 0.5-5g / L sodium chloride 5-10g / L phosphoric acid Dipotassium Hydrogen 1~5g / L Manganese Sulfate 0.1~2g / LpH7.0~7.2
[0057] 2. Bacillus coagulans secondary liquid seeds
[0058] Inoculate the single colony of the primary Bacillus coagulans in step 1 into the secondary culture medium, the liquid volume is 50-100mL / 500mL, and cultivate it under the conditions of 30°C-45°C and 160-300rpm / min for 20-32h to obtain the secondary culture medium Bacillus coagulans seed solution.
[0059] The secondary liquid medium is a mixed solution (g / L) prepared according to the following ratio: gl...
Embodiment 3
[0067] A preparation method of a spore preparation of bacillus coagulans, comprising:
[0068] 1. Bacillus coagulans primary tube slant seeds
[0069] The original bacteria were inoculated on the primary slant medium, and cultured at 30°C-45°C for 20-32h.
[0070] The primary slant medium is a mixed solution (g / L) prepared according to the following ratio: yeast extract 5-15g / L peptone 5-15g / L glucose 0.5-5g / L sodium chloride 5-10g / L phosphoric acid Dipotassium Hydrogen 1~5g / L Manganese Sulfate 0.1~2g / L, Agar 15~20g / L, pH7.0~7.2
[0071] 2. Secondary solid seeds of Bacillus coagulans
[0072]Inoculate the single colonies of the primary Bacillus coagulans in batches in the secondary eggplant-type culture flasks in step 1, culture them at 30°C-45°C for 36-48 hours, and store them at 4°C for 24 hours.
[0073] The medium in the described secondary eggplant type culture flask is the same as that in step 1.
[0074] 3. Solid fermentation culture of Bacillus coagulans
