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.
摘要:
Provided is a method for producing alcohol or hydrogen gas comprising culturing alcohol-producing microorganisms in a waste fermented solution generated from the bioethanol production process. Glycerol included in the waste fermented solution generated from the bioethanol production process is converted by the microorganisms to butanol under an anaerobic condition. Since the waste fermented solution generated from the bioethanol production process can be utilized as a source of a biofuel, environmental and energy problems can be solved at once.

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.
