“…Van Zyl et al [98] suggested that the detoxification effect of overliming was due to precipitation of toxic substances. Persson et al [35] collected and analyzed precipitated material as well as the chemical composition of alkalitreated hydrolysates and concluded that the detoxification effect was due to chemical conversion rather than to removal of precipitated inhibitors.…”

“…Van Zyl, Prior and Du Preez (1988) reported that, due to inhibition degree dependent on acid concentration and pH, the acetic acid is a major inhibiting compound in the bioconversion of P. stipitis in ethanol. When mixed with other inhibitors, the effect of degradation is intensified, due to the fact that yeast is sensitive to organic acids in lignocellulosic hydrolyzate.…”

ABSTRACT. Biomass from lignocellulosic material constitutes a promising energy alternative and without competing with food production. However, pretreatments are required for conversion into sugars which release hexoses, pentoses and other sugars, coupled to inhibitors. Current analysis focuses on ethanol production with the three major inhibitors of lignocellulosic biomass pretreatment, namely, acetic acid, furfural and 5-hydroxymetilfurfural (HMF), and investigates the influence of a mixture of these inhibitors on fermentation by Pichia stipits, using commercial xylose as the only carbon source, through a full factorial 2 3 + 3 design of experiments (DOE). Fermentations were conducted in a laboratory scale, at 150 rpm and 72h, in a complex culture media with xylose and different inhibitor concentrations, based on the experimental analysis of sugarcane bagasse and 2.10 .
