摘要
More particularly, the present invention relates to a method for producing an organic acid by fermentation of an organic acid by microbial organic acid fermentation, and more particularly to a method for producing an organic acid by fermentation of an organic acid by a microorganism, Separating the fermentation reaction liquid in which the fermentation reaction is performed by the microorganism into a fermentation broth as a result of the fermentation reaction; b) lowering the pH of the fermentation broth; c) extracting the organic acid from the fermentation broth in which the pH of the fermentation broth is lowered by bringing the fermentation broth in the step b) into contact with the organic solvent for extracting organic acid; And d) bringing the pH of the fermentation broth in which the pH of the fermentation broth from which the organic acid extracted in Step c) has been increased to the fermentation reaction solution in which the fermentation reaction by the microorganism of the step a) is performed A method for producing organic acid by microbial organic acid fermentation, and an apparatus for carrying out the method.According to the present invention, it is possible to produce organic acids continuously and with high efficiency without deteriorating organic acid production efficiency by adjusting the pH to an optimum condition organically throughout the whole process, and further, there is no pH adjusting agent added separately, And it is possible to provide an organic acid production method free from the problem of salt accumulation in the reaction solution.
