Embodiment 1
[0021] The seeds for fermented production are obtained by separately cultivating nitrogen-fixing bacillus phenosphere, bacillus megaterium, jelly-like bacillus, bacillus licheniformis and bacillus macerans.
[0022] Prepare the fermentation medium in the fermenter according to the production medium formula as follows (per liter): 3g of sucrose; 5g of mannitol; 1g of ammonium sulfate; 2g of peptone; 1g of beef extract; 1g of sodium chloride; Ammonium Acid 0.3g; Calcium Carbonate 0.1g; Trace amount of Ferrous Chloride. Adjust the pH to 7.2 and sterilize.
[0023] After the fermentation medium is cooled to 30°C, insert the cultured seeds under aseptic conditions as follows (per liter): 2 mL of Azotobacter sphaeroides, 3 mL of Bacillus megaterium, 1.5 mL of Bacillus jelly-like, 1.5 mL of Bacillus licheniformis and soaked Bacillus hempensis 1.5mL.
[0024] After cultivating at 33°C for 25 hours under the condition of aerobic ventilation and stirring, the culture was stopped, and ...

[0026] The seeds for fermented production are obtained by separately cultivating nitrogen-fixing bacillus phenosphere, bacillus megaterium, jelly-like bacillus, bacillus licheniformis and bacillus macerans.
[0027] Prepare the fermentation medium in the fermenter according to the production medium formula as follows (per liter): 5g of sucrose; 12g of mannitol; 1.6g of ammonium sulfate; 3g of peptone; 1.8g of beef extract; 2g of sodium chloride; ; Ammonium molybdate 0.4g; Calcium carbonate 0.15g; Trace amount of ferrous chloride. Adjust the pH to 7.4 and sterilize.
[0028] After the fermentation medium is cooled to 35°C, insert the cultured seeds under aseptic conditions as follows (per liter): 2.8 mL of Azotobacter sphaeroides, 3.5 mL of Bacillus megaterium, 1.8 mL of Bacillus jellylike, and 1.8 mL of Bacillus licheniformis and Bacillus macerans 1.5mL.
[0029] After cultivating at 35°C for 27 hours under aerobic and stirring conditions, the culture was stopped, and the nu...
Embodiment 3
