The current project aims to integrate lignosulfonate and xylan production in a biorefinery processing sugarcane bagasse, and explores the transformation of the lignosulfonates and hydroxycinammic acids linked to xylans through enzymatic and chemical reactions to produce adhesives. The experimental approach of the project can be divided into two main frameworks: 1) The oxidative transforma…
The project will provide integrated knowledge related to the sugar cane cell wall recalcitrance. Based on this knowledge, innovative biorefinery models will be proposed for the conversion of the sugar cane biomass into valuable products. Secondary cell wall formation will be evaluated along complete maturation cycles experimental hybrids that contrast for lignocellulose composition. UV- a…
The central part of the sugar cane internodes (pith) was used as a substrate to evaluate sugar cane digestibility by acessory enzymes combined with cellulases and xylanases. Acetyl xylan esterase (TrAXE) was more efficient in enhancing the overall saccharification of sugar cane as compared to the feruloyl esterases AnFaeA, TsFaeC and NcFaeD. The hydroxycinnamic acid composition of sugar c…

One of the current challenges for biorefineries is to diversify products beyond liquid fuelsand process energy. New products from plant biomass can aggregate value to the productionchain and boost the commercial implementation of biorefineries. Some biorefinery modelsderived from traditional pulp and paper industry (alkaline sulfite process, for example) cangenerate sulfonated lignin (or …
The lignocellulosic material biorefineries are suitable for production of fuels and chemicals, considering lignocellulose abundance in agroindustrial residues. Cellulose and hemicellulose conversion into monosaccharides and other chemical feedstocks is currently well developed. However, lignin fraction is still underutilized, with main use associated with combustion for steam and energy p…
The lignocellulosic material utilization in the context of biorefineries complies with the current demand for more sustainable technologies, covering several integrated processes. In this context, hemicellulose, an important natural resource, is one of the main components found in lignocellulosic biomass and has great potential for biotechnological applications in several sectors of the i…

Among the microorganism that decompose lignocelullosic material it is possible to find the brown root fungi, which degrade polysaccharides, mainly the cellulose and hemicellulose, leaving a rich residue in lignin content. This fungal action seems to occur by a non-enzymatic pathway known as Fenton reaction. This reaction involves the formation of hydroxyl radicals based on decomposition o…
