Abstract

Microorganisms capable of utilizing D-xylose as a sole carbon and energy source were isolated to ferment D-xylose directly to ethanol. Among them, the strain, which showed the best ability to pro-duce ethanol, was selected and was identified as Fusarium sp. The optimal conditions for the pro-duction of ethanol were 8.0 of initial pH, 33$^{\circ}C$ of temperature, and 2% of substrate concentration. Under this optimal condition, the following results were obtained : maximum ethanol concentration, 7.0g/$\ell$; ethanol yield, 0.35g of ethanol per g of D-xylose (68.6% of theoretical); biomass yield, 0.27g of dry biomass per g of D-xylose.
