前言现代发酵工业以大规模的液体深层发酵为特征。一家企业日产发酵液有几百m~3甚至几千m~3,而小分子产品在水性液体(发酵液)中含量大都在10％以下,许多高价值或大分子产品浓度更低,有的甚至低于1％。按目前情况。生产1t产品要排放15～ Introduction The modern fermentation industry features large-scale liquid deep fermentation. A company’s Nissan fermentation broth has several hundred m~3 or even several thousand m~3, while the small molecule product has a content of less than 10% in aqueous liquids (fermented liquor). Many high-value or macromolecular products have lower concentrations, and some Even less than 1%. According to the current situation. 1t product to produce 15 ~
