• Abstract

  Results from ongoing and recent research at EEL-USP (FAPESP: Processes 2013/27142-0 and 2016/22179-0) point to the technical feasibility of the biotechnological route for xylitol production by Candida guilliermondii FTI 20037 (recently identified as C. tropicalis) with the concomitant use of sugarcane bagasse and straw. However, there are still bottlenecks to be solved, such as the simpli…

• Abstract

  Different approaches will be applied to improve the technical and economic feasibility of xylitol production bioprocess from a mixture of sugarcane bagasse and straw in the biorefinery concept for the sugar-alcohol sector. One of the aims is to increase the capacity of the yeast Candida guilliermondii FTI 20037 to bioconvert the xylose present in the hemicellulose to xylitol by optimizing…

  Improvements of xylitol production bioprocess in the biorefinery concept for diversification of product portfolio of sugar-and-alcohol sector, AP.R

• Abstract

  This project aims to develop a technology platform for incorporation of sugarcane straw (tops, green and dry leaves) as feedstock in a biorefinery, using as study models the biotechnological production of xylitol from hemicellulose fraction and energy production from combustion of cellulignin. Sugarcane straw becomes a renewable, abundant and available lignocellulosic material from mechan…

• Abstract

  This project proposes the development of a biotechnological process concerning the xylitol production based upon the utilization of sugarcane bagasse, straw and molasses, aiming at the integration of this bioprocess with the sugar and alcohol process in the context of a biorefinery. Significant progresses achieved in xylitol production from different lignocellulosic biomasses in the "Esco…
