METHOD FOR PRODUCTION OF BIO-ETHANOL BY USING BLUEGREEN ALGAE FROM FRESH WATER

摘要

A method for producing ethanol using bluegreen algae in the freshwater is provided to improve economic efficiency of ethanol using eco-friendly bluegreen algae which is easy to obtain. A method for producing ethanol comprises: a step of drying for 40-60 minutes using supercritical fluid carbon dioxide; a step of neutralizing by adding acid; a step of adding ethanol production strain and fermenting at 30~50‹C; a step of adding 5~15 weight part of hydrochloric acid; and a step of lowering at 20~30‹C, and adding 8~12%(w/v) of sodium hydroxide aqueous solution.
