METHOD FOR PRODUCING ORGANIC ACIDS FROM BIOMASS

摘要

The present invention relates to a method for producing organic acids from biomass, and more specifically relates to a method for producing various organic acids (volatile fatty acids) from land-based, freshwater-based, marine or biodegradable organic mixed biomass by using a high-density cell culture method, and then concentrating and distilling the same. The method for producing organic acids from biomass comprises the steps of: (a) producing organic acids by fermenting biomass; (b) concentrating the organic acids so produced by at least 30%; and (c) recovering the organic acids by fractional distillation of the concentrated organic acid. A method for isolating organic acids produced economically from biomass according to the present invention can be used to advantage in converting organic acids into fuel or compounds such as alcohols, esters and alkanes in addition to the economic use of organic acids.
