TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The cultivating process involves inoculating the B.licheniformis to inclined substrate, cultivating the B.licheniformis in cultivating case for 24 hours, storing the obtained inclined bacteria at 0-4 degrees C, and using the stored B.licheniformis within one year, and disposing the obtained B.licheniformis in the substrate of swing bed for swinging and cultivating for 24-30 hours at 200 revolution/minute (rpm), where the inclined substrate comprises (in parts weight): glucose (1-3), peptone (0.1-0.5), yeast powder (0.3-0.5), beef extract (0.3-0.7), ammonium hydrogen phosphate (0.3-0.5), dipotassium hydrogen phosphate (0.03-0.05), magnesium sulfate heptahydrate (0.02-0.05), sodium chloride (0.1-0.6), manganese sulfate (0.001-0.003) and remainder water. The fermentation process involves fermenting first-level liquid by adding the substrate to a small fermentation tank for high temperature sterilization at 121 degrees C under pressure of 1 kg/cm2, maintaining mixture for 30 minutes, controlling pH value of the mixture to 7.5 before sterilization and to 6.5 after sterilization, inoculating the swing bottle for cultivation to obtain 3% of bacterium liquid after the temperature is 35 degrees C, fermenting mixture under 0.2 kg/cm2 pressure, cultivating bacteria for 24-30 hours to obtain first-level seed liquid, (2) fermentation of the second-level liquid by sterilizing intermediate fermentation tank, small fermentation tank and intermediate inoculating pipeline, where the inner pressure of the inlet air valve is 1.2 kg/cm2, cooling, fermenting with the same conditions to obtain the second-level seed liquid, and (3) fermentation of the three-level liquid by pressing the second-level seed liquid in the large fermentation tank in proportion of 1:100, cultivating bacteria for 66-72 hours, forming a spore by 95% of thallus and terminating the cultivation. The fermenting process is performed at 321, preferably 371 degrees C. The spore content in the three-level liquid detected using blood ball counting plate method is 5000000000, preferably 10000000000 or more taken as standard for disposing in the tank. The viable bacteria number of the manure is 5000000000 or more, and corn element content is 8 mu g/ml or more. Preferred Components: The substrate of swing bed comprises glucose (2-6), bean cake powder (2-5), pulp powder (1-3), peptone (0.1-0.5), yeast powder (0.3-0.5), beef extract (0.3-0.7), ammonium hydrogen phosphate (0.3-0.5), dipotassium hydrogen phosphate (0.03-0.05), magnesium sulfate heptahydrate (0.02-0.05), sodium chloride (0.1-0.6), manganese sulfate (0.001-0.003) and remainder water. The three-level liquid comprises glucose (2-6), bean cake powder (2-5), pulp powder (1-3), peptone (0.1-0.5), yeast powder (0.3-0.5), beef extract (0.3-0.7), ammonium hydrogen phosphate (0.3-0.5), dipotassium hydrogen phosphate (0.03-0.05), magnesium sulfate heptahydrate (0.02-0.05), sodium chloride (0.1-0.6), manganese sulfate (0.001-0.003) and remainder water.
