[0011] A preparation method of microbial granule preparations for water purification of aquaculture water bodies, the specific method includes the following steps: (1) Picking a loop of Bacillus subtilis strains activated by inclined planes and inoculating seed culture medium in a triangular flask, and placing 30 In a constant temperature shaker at ~37℃, shake culture at 120~150 rpm for 18~24 hours to obtain liquid first-grade Bacillus subtilis seeds with a bacterial content of at least 1×10 8 Pieces / ml; (2) Connect the above-mentioned liquid first-level seeds to the seed culture medium in the seed tank at a ratio of 1% of seed liquid: seed culture medium, and after inoculation, the temperature is 30~37℃ and the tank pressure is 0.05 MPa , The aeration ratio is 1:1, and the stirring speed is 150~200 rpm. Cultivate for 10~12 hours to obtain B. subtilis liquid secondary seed, which contains at least 2×10 8 Pcs / ml; (3) Inoculate the above secondary seeds of the bacteria liquid into ...

[0020] One loop of Bacillus subtilis strains activated by the slope was inoculated into an Erlenmeyer flask, (medium formula: peptone 10 g / L, beef powder 3 g / L, NaCl 5 g / L, glucose 1 g / L, use 1 mol / L HCl and 1 mol / L NaOH adjust the pH to 7.2), place it in a constant temperature shaker at 37°C and shake culture at 150 rpm for 18 hours to obtain liquid first-level seeds of Bacillus subtilis, with a concentration of 10 8 Pieces / ml; connect the liquid first-level seeds to the seed tank at a ratio of 1% of seed liquid: seed medium (medium: peptone 10 g / L, beef powder 3 g / L, NaCl 5 g / L, glucose 1 g / L, adjust the pH to 7.2 with 1 mol / L HCl and 1 mol / L NaOH, the total volume after sterilization is 70% of the seed tank volume), after inoculation, the temperature is 37℃, the tank pressure is 0.05 MPa , The aeration ratio is 1:1, and the stirring speed is 150 rpm for 10 hours. The obtained Bacillus subtilis secondary seed liquid grows neatly without contamination by bact...

[0022] One loop of Bacillus subtilis strains activated by the inclined plane was inoculated into an Erlenmeyer flask. (Medium formula: peptone 10 g / L, beef powder 3 g / L, NaCl 5 g / L, glucose 1 g / L, use 1 mol / L HCl and 1 mol / L NaOH adjust the pH to 7.4), place it in a constant temperature shaker at 30°C, shake culture at 120 rpm for 24 hours, and obtain liquid first-level seeds of Bacillus subtilis, with a concentration of 10 8 Pieces / ml; connect the liquid first-level seeds to the seed tank at a ratio of 1% of seed liquid: seed medium (medium: peptone 10 g / L, beef powder 3 g / L, NaCl 5 g / L, glucose 1 g / L, adjust the pH to 7.4 with 1 mol / L HCl and 1 mol / L NaOH, the total volume after sterilization is 67% of the seed tank volume), after inoculation, the temperature is 30℃, the tank pressure is 0.05 MPa , The aeration ratio is 1:1, and the agitating speed is 200 rpm. After 12 hours of cultivation, the obtained Bacillus subtilis secondary seed liquid grows neatly wi...
