[0051] 1. Composite strain starter preparation methods
[0052] Strain culture on inclined plane→liquid first-level seed (shake flask) culture→liquid second-level (seed tank)→fermentation tank culture→high-speed centrifuge→vacuum freeze dryer→crusher→determination of bacteria count→combination of bacteria in proportion→packaging → Finished starter.
[0053] Seed culture: Utilize any one of the above strains and adopt conventional experimental conditions to cultivate, that is, to use carbohydrates as carbon sources (the carbohydrates can be glucose, sucrose, lactose, fructose, maltose, starch, etc.) One or more of them), peptone, yeast extract or beef extract as nitrogen source, and appropriate amount of inorganic salts and trace elements are added, and deionized water is used to prepare a solution as a seed medium, and the liquid bacterial Kind, ready to use. Since the cultivation process of the above bacterial strains refers to the cultivation method described in the Chine...
