A. aEvaluating the composition and processing potential of novel sources of Brazilian biomass for sustainable biorenewables production.h[electronic resource] c2014 aThe search for promising and renewable sources of carbohydrates for the production of biofuels and other biorenewables has been stimulated by an increase in global energy demand in the face of growing concern over greenhouse gas emissions and fuel security. In particular, interest has focused on non-food lignocellulosic biomass as a potential source of abundant and sustainable feedstock for biorefineries. Here we investigate the potential of three Brazilian grasses (Panicum maximum, Pennisetum purpureum and Brachiaria brizantha), as well as bark residues from the harvesting of two commercial Eucalyptus clones (E. grandis and E. grandis x urophylla) for biofuel production, and compare these to sugarcane bagasse. The effects of hot water, acid, alkaline and sulfite pretreatments (at increasing temperatures) on the chemical composition, morphology and saccharification yields of these different biomass types were evaluated. aBioethanol aChemical composition aEucalyptus aScanning electron microscopy aSugarcane bagasse aBrachiaria Brizantha aComposição Química aPanicum Maximum aPastagem aPennisetum Purpureum aBioalcool1 aGOMEZ, L.
