Example Embodiment
[0028] The method for fermentation and cultivation of microorganisms of the present invention includes the following process steps:
[0029] 1. According to the process requirements, select suitable bacillus to produce seeds, and use conventional separation and purification treatment to activate and revive the bacteria;
[0030] 2. Primary seed culture: inoculate the activated Bacillus strains into the primary seed liquid medium and cultivate for 6-24 hours at 30-40°C;
[0031] 3. Heat treatment of the first-level seed liquid: heat-treat the first-level seed liquid obtained in step 2: the treatment temperature is 60-90°C, and the time is 5-60 minutes;
[0032] The effect of heat treatment increases the synchronization of microbial growth and improves the adaptability of microorganisms to higher temperatures. The selected strains are more resistant to high temperatures, and strains that cannot adapt to high temperatures are eliminated;
[0033] 4. Second-level seed culture: P...
