ABSTRACT:
The present invention deals with an improved fermentation process for the production of xylitol fromPichiasp. and the said process is submerged fermentation for the production of xylitol using cotton seed flour as cheap organic nitrogen source and the main advantage is short fermentation time and higher yield of xylitol from xylose moreover, one of the essential aspects of the present invention is that the medium for the fermentation usingPichiasp. for producing high yield of xylitol from xylose has been obtained using a specific combination of nutritional parameters.
