METHOD FOR MANUFACTURING A WOOD BIO-MASS SACCHARIFIED LIQUID HAVING REDUCED OR ELIMINATED TOXICITY, AND METHOD FOR MANUFACTURING ORGANIC ACIDS OR BIOFUELS USING SAME

摘要

Provided in the present disclosure is a method for detoxification of a wood bio-mass saccharified liquid having reduced or eliminated toxicity, characterized by comprising the steps of: preparing a saccharified liquid in which a wood bio-mass is subjected to a hydrolysis pre-treatment; and reducing the toxicity of the saccharified liquid by adding a surfactant thereto. The method for detoxification according to the present disclosure enables effective elimination of the toxicity of lignin-derived compounds, which are produced during the pre-treatment, and inhibition of the growth and fermentation of microorganisms. Further, the detoxification method can improve manufacturing efficiency by minimizing additional costs without loss of saccharide during detoxification.
