PREPARATION METHOD FOR BIOFUELS AND BIOCHEMICALS FROM LIGNOCELLULOSIC BIOMASS

摘要

PURPOSE: A method for preparing bio fuel or bio chemical is provided to efficiently use lignocelluloses biomass and to save energy and cost for additional nutrient. CONSTITUTION: A method for preparing bio fuel comprises a step of fermenting hexose from a mixture of pentose and hexose to prepare an ethanol fermentation liquid. The method also comprises a step of preparing a culture medium containing fermentation waste; a step of inoculating a first microorganism in the culture medium; and a step of culturing. The fermentation water contains hexose including glucose, galactose, and mannose or pentose including xylose and arabinose.
