The present invention relates to a method for producing an organic acid from biomass, and more particularly, to produce an organic acid (volatile fatty acid) from terrestrial, aquatic, marine or biodegradable organic mixed biomass by a high concentration cell culture method, and then Concentrates and distills to produce each organic acid. The method of producing an organic acid from the biomass includes the steps of (a) fermenting the biomass to produce an organic acid; (b) concentrating the produced organic acid to at least 30%; And (c) recovering the organic acid by fractional distillation of the concentrated organic acid. The method for separating economically produced organic acid from the biomass according to the present invention can be usefully used not only for the economic use of the organic acid but also for converting the organic acid into a compound or fuel such as alcohol, ester, alkane or the like. |
