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%.

Abstract: A method for preparing a xylose-utilizing strain of Saccharomyces cerevisiae and the Saccharomyces cerevisiae are introduced. The preferred recombinant strain contains multiple copies of integrated xylose metabolic genes, and can rapidly ferment xylose to produce ethanol from synthetic medium and lignocellulosic raw materials. The xylose-utilizing strain is applicable for the cellulosic ethanol production industry and brewing industry.

Abstract: A method for culturing the yeast for enhancing pentitol production is provided. The yeast cultured according to the present disclosure is Pichia stipitis. Application of the yeast in pentitol production by fermention of the lignocellulosic hydrolysate or the xylose-to-pentitol production yield can be enhanced 3 to 6 times from the non-detoxified or the overliming-processed lignocellulosic hydrolysate.

Abstract: A hydrolysate-adapted yeast, Pichia stipitis INER 1128, is cultivated according to the present invention. The adapted yeast can effectively convert xylose into ethanol in lignocellulosic hydrolysate, which is not even detoxified. Well ethanol yield is obtained while xylose is not wasted and thus cost is reduced.

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 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.
