深层发酵(submerged fermentation)是将菌种培养在发酵罐或锥形瓶内,通过不断透气搅拌或振荡,使菌体在液体深层外繁育的方法,能在短期内获得大量的菌体和代谢物,由于其具有生产周期短、培养液中产生的活性物质多、产量高、菌体污染少等特点,为在食品工业和医药行业开发重要的代谢物、真菌药物的原料和生产功能性饲料等提供了有效手段。 Submerged fermentation is the culture of bacteria in a fermentor or conical flask, by constant aeration stirring or shaking, so that bacteria in the liquid deep breeding methods can be obtained in a short period of a large number of bacteria and metabolites , Due to its short production cycle, the active substances generated in the broth, high yield, less bacterial contamination, etc., in the food industry and the pharmaceutical industry to develop important metabolites, fungal drugs, raw materials and the production of functional feed, etc. Provide an effective means.
