BACKGROUND Previous studies on the use of SO2 and CO2 as impregnating agent for sugar cane bagasse steam treatment showed comparative and promising results concerning the cellulose enzymatic hydrolysis and the low formation of the inhibitors furfural and hydroxymethylfurfural for the use of CO2 at 205°C/15 min or SO2 at 190°C/5 min. In the present study(More)
Endocytic activity is particularly intense in Trypanosoma cruzi epimastigotes, while in amastigotes and trypo-mastigotes it is untraceable. Cargo molecules enters through the cytostome or flagellar pocket at the parasite anterior region , goes along a branched early endosomal network of tubules and vesicles spread from nuclear periphery to the posterior(More)
Conversion of sugarcane bagasse to bioethanol is hindered due to intrinsic biomass recalcitrance that is related to its chemical composition and physicochemical properties. Furthermore, biomass heterogeneity interferes with process effectiveness. To compare sugarcane culm recalcitrance epidermis, internode and node fractions were individually investigated(More)
