    Abstract: A method is provided for improving the efficiency of xylose fermentation in lignocellulosic hydrolysate. The disclosed embodiment raises the efficiency of xylose conversion by adding a specific lignocellulosic material during fermentation. In particular, a 10% enhancement in the efficiency of xylose conversion for ethanol production was given, and the ethanol yield is achieved 90% after adding the specific lignocellulosic material.

    Abstract: The present disclosure is related to a method for increasing the ethanol concentration from the conversion of lignocellulose. The pretreated solid residues are mixed with ethanol-containing broth from the fermentation of xylose hydrolysate by Pichia stipitis and then are performed under the process of simultaneous saccharification and fermentation (SSF) with Sacharomyces cerevisiae and cellulase for converting cellulose to ethanol. The final ethanol concentration in broth as well as the ethanol productivity is increased at least 1.8 times in comparison of conventional process for lignocellulosic ethanol production.

    Abstract: A method for producing xylitol by fermentation of lignocellulosic hydrolysates without detoxification is provided. By using the originally isolated yeast Candida sp., xylose can be effectively converted into xylitol. The invention also provides the Candida strain having high furfural tolerance, and is capable to produce xylitol from various types of non-detoxified lignocellulosic hydrolysates, in which the overall utilization of xylose in hydrolysate can reach over 95%.
