Thirty acid hydrolysis conditions for the second hydrolysis of the classic method to quantify lignin and polysaccharides were performed in eucalyptus, sugarcane bagasse, and sugarcane straw. Ethanol production from olive stone hydrolysates by xylose fermenting microorganisms. When cellulosic fibres are subjected to acid, the glucosidic linkages in the cellulose are … This experiment aims to determine the effect of temperature on the enzyme Ethers and acetals, promising petrochemicals from renewable sources. A strategy for the simultaneous catalytic conversion of hemicellulose and cellulose from lignocellulosic biomass to liquid transportation fuels. The application of concentrated sulphuric acid made it possible to avoid high pressure and temperature [25] at the synthesis stage. The overestimation of lignin in harsher acidic conditions resulted from the summation of lignocellulosic-derivatives (pseudo-lignin) together with lignin itself.

Under similar conditions, the values for quantifiable Klason lignin were only 1.1, 1.4, and 1.5 times higher compared with the classic method, for eucalyptus, bagasse, and straw, respectively (Table S1, S2, and S3). Acid hydrolysis can be used for the preparation of monosaccharide. In organic chemistry, acid hydrolysis is a hydrolysis process in which a protic acid is used to catalyze the cleavage of a chemical bond via a nucleophilic substitution reaction, with the addition of the elements of water (H 2 O). The model generated for Klason lignin in eucalyptus produced a negative signal for the coefficient associated with acid concentration in the quadratic term, along with a non-significant effect of acid concentration on the linear term.
