METHOD FOR PURIFYING CARBOXYLIC ACIDS FROM FERMENTATION BROTHS

摘要

The invention relates to a method for separating and purifying carboxylic acids from fermentation broths, comprising the following steps: a) separating the biomass and any solid materials that may be present from the fermentation broth, b) using nanofiltration for the fine-purification of the fermentation broth from method step a), and c) separating the carboxylic acid by means of adsorption to one or more solid phases which have tertiary amino groups.
