NOVELTY - Preparing Bacillus licheniformis microcapsules involve inoculating Bacillus licheniformis in liquid medium at 6.4-7.5 pH at 35-40 degrees C at 160-280 rotations per minute for 10-18hours to obtain activated liquid culture. The obtained activated liquid culture (2-7%) is inoculated in fresh liquid medium at 6.4-7.5 pH in Erlenmeyer flask at 35-40 degrees C at 160-280 rotations per minute for 2-6 hours to obtain seed liquid culture. The obtained seed liquid culture is centrifuged at 4 degrees C for 10-40minutes at 3000-8000 rotations per minute.    USE - Method for preparing Bacillus licheniformis microcapsules (claimed) used in health, medicine and food industries.    ADVANTAGE - The method enables to prepare Bacillus licheniformis microcapsules are green, safe and eco-friendly, and maintains high survival rate and environmental tolerance of Bacillus licheniformis.    DETAILED DESCRIPTION - Preparing Bacillus licheniformis microcapsules involve inoculating Bacillus licheniformis in liquid medium at 6.4-7.5 pH at 35-40 degrees C at 160-280 rotations per minute for 10-18hours to obtain activated liquid culture. The obtained activated liquid culture (2-7%) is inoculated in fresh liquid medium at 6.4-7.5 pH in Erlenmeyer flask at 35-40 degrees C at 160-280 rotations per minute for 2-6 hours to obtain seed liquid culture. The obtained seed liquid culture is centrifuged at 4 degrees C for 10-40minutes at 3000-8000 rotations per minute. The obtained precipitate is added with water in ratio of 1:4-8. The obtained mixture is centrifuged at 4 degrees C for 10-40minutes at 3000-8000 rotations per minute. The obtained precipitate is washed (2-3 times), and suspended in sterile water to obtain bacterial suspension having concentration of 109 colony forming units/ml. The obtained bacterial suspension is added to polyanion electrolyte solution for aseptic processing method under oscillating conditions to obtain aqueous phase cell suspension. The concentration of polyanion electrolyte solution is 0.01-0.04g/mL. External aqueous phase A solution is prepared by mixing 0.04-0.1g/mL small molecule, and external aqueous phase B solution is prepared by mixing 0.005-0.03g/mL small molecule in polycation electrolyte solution. The aqueous phase cell suspension is mixed with external aqueous phase A solution (15-60ml) at 450-850 mu l/minute flow rate at 200-500 rotations per minute at room temperature for 5-35minutes to obtain microcapsules, which are added with sterile water and external aqueous phase B solution (15-60ml) at 200-500 rotations per minute. The obtained product is collected and washed with sterile water to obtain wet microcapsules. The obtained wet microcapsules are dried under vacuum to obtain Bacillus licheniformis microcapsules.
