Ethanol production from rice straw hydrolysates by Pichia stipitis

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.
