Embodiment 1
[0016] 1. Bacillus products: commercially available Bacillus subtilis products;
[0017] 2. Method:
[0018] Activation of Bacillus subtilis-like products
[0019] Weigh 10g of Bacillus subtilis products, 30g of glucose, and 100g of soybean meal powder into 1.8kg of water at 33-37°C, and place for 4 hours.
[0020] Cultivation of Bacillus products
[0021] Put the activated bacillus products into a container containing 3kg soybean meal powder, mix evenly, cover with a piece of gauze, and place in a room at 25-30°C. Incubate for 48 hours.
[0022] Temperature records of the culture process of bacillus products
[0023] Measure the temperature of the fermentation material once in the morning, middle and evening.
[0024] Within 48 hours, the feed temperature rose to a maximum of 51°C.
[0025] 3. Quality determination of Bacillus subtilis products
[0026] The bacillus subtilis product is qualified and has bacillus activity.
Embodiment 2
[0028] 1. Bacillus products: commercially available Bacillus licheniformis products;
[0029] 2. Method:
[0030] Activation of Bacillus licheniformis products
[0031] Weigh 10g of Bacillus licheniformis products, 30g of glucose, and 100g of soybean meal powder into 1.8kg of water at 33-37°C, and place for 4 hours.
[0032] Cultivation of Bacillus licheniformis products
[0033] Put the activated bacillus products into a container containing 3kg soybean meal powder, mix evenly, cover with a piece of gauze, and place in a room at 25-30°C. Incubate for 48 hours.
[0034] Temperature records of culture process of Bacillus licheniformis products
[0035] Measure the temperature of the fermentation material once in the morning, middle and evening.
[0036] Within 48 hours, the feed temperature rose to a maximum of 47°C.
