The objective of this study was aimed to evaluate the fermentability of rice straw hydrolysates by P.stipitis and
proposed the fermentation process available. Both of glucose and xylose in mixture of dilute acid hydrolysate and
enzymatic hydrolysate were completely utilized with an ethanol yield of 0.47 g/g. This result proved that the
hydrolysate mixture was more suitable for ethanol fermentation by P.stipitis and this organism has shown great
potential for the development of novel co-fermentation processes designed to obtain lignocellulosic ethanol
production.
