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 mechanized harvesting implementation, as function of the imminent need for sustainable processes. Besides its agronomic benefits, this biomass can be used in various industrial segments. In this context, the activities proposed include the use of hemicellulosic fraction by biotechnological route and cellulignin by thermochemical route. In this regard, activities related to the physicochemical characterization of sugarcane straw are planned, followed by biomass acid hydrolysis to obtain hemicellulosic hydrolysate rich in sugars and cellulignin. In the case of the hydrolyzate, after its chemical characterization, it will be used in formulation of the fermentation medium for xylitol production. In these experiments the yeast Candida guilliermondii FTI 20037 will be employed, whose potential in xylose-to-xylitol bioconversion is already recognized. Regarding to cellulignin, the proposed steps involve its physico-chemical characterization, kinetic study of its thermal decomposition, combustion and factor of gases emission during combustion, compared to biomass in natura, which will be submitted to the same processes. Thus, with the development of this project is expected to achieve scientific basis for proposing alternatives incorporation of sugarcane straw in a biorefinery. (AU)
