A method for producing xylitol by fermentation of lignocellulosic hydrolysates without detoxification is provided. By using the originally isolated yeastsp., xylose can be effectively converted into xylitol. The invention also provides thestrain 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%.

Method for producing xylitol from lignocellulosic hydrolysates without detoxification

A method for preparing a xylose-utilizing strain ofand theare 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.

A method for culturing the yeast for enhancing pentitol production is provided. The yeast cultured according to the present disclosure is. 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.
