摘要： Disclosed is a method for detoxifying a lignocellulosic biomass hydrolysate, including: preparing a hydrolysate by pretreating a lignocellulosic biomass by hydrolysis; and decreasing or removing toxicity by adding a surfactant to the hydrolysate. The detoxifying method according to the present disclosure may effectively remove toxicity of compounds derived from lignin that inhibit the growth of and fermentation by microorganisms during the pretreatment of lignocellulosic biomass. Further, production efficiency can be improved since loss of sugar can be avoided during the detoxification and additional cost can be minimized.

摘要： Disclosed is a method of converting butyric acid contained in a fermentation broth into biofuel. This chemical conversion method includes separating biohydrogen from gases generated in the course of production of butyric acid through fermentation of carbohydrate, extracting butyric acid from the broth using an insoluble solvent, esterifying butyric acid thus producing butylbutyrate, and hydrogenolyzing all or part of butylbutyrate, thus obtaining butanol. Thereby, biobutanol can be efficiently and economically produced, and butylbutyrate, which has oxidation stability superior to that of conventional biodiesel (fatty acid methyl ester) and is thus regarded as novel biofuel, can be produced together.
