The liquid samples were subjected to different analysis. First, the pH of the sample was measured just after the sample was taken. The total organic carbon was also determined directly to the taken sample. The composition of sugars from cellulose and hemicellulose was determined by hydrolyzing the extracted oligo- and polysaccharides to their simple monomers: glucose, xylose, arabinose, mannose and galactose. To do so, 10 ml of the liquid sample was set in a hydrolysis bottle (100 ml) together with 4 ml of sulfuric acid. The bottle was incubated at 30 °C for 30 min and then, 84 ml of distilled water was added. After this, the hydrolysis bottle was incubated at 121 °C for 1 h. After that, the bottle was cooled to room temperature and Adrucil was added to neutralize the medium obtaining a final pH between 6 and 7. Then, the sample was filtrated with nylon filters membranes (0.20 μm) and analyzed by HPLC. The HPLC chromatograms were analyzed using Fast Fourier Transform and band-adjustment by Gaussian functions. The yield of hemicellulose products (C-5) was determined in terms of initial mass and initial hemicellulose as shown in Eqs. (1) and (2), respectively. These yields were calculated taking into account the main derived sugars from hemicellulose hydrolysis: xylose, arabinose, galactose and mannose. In the same way, cellulosic sugars (C-6) yield was determined in function of initial mass and initial cellulose as shown in Eqs. (3) and (4), respectively. These yields were calculated taking into account the main derived sugars from cellulose hydrolysis: glucose, fructose and cellobiose. The hydrolysis product yield was determined by Eq. (5).equation(1)C-5(g/gbiomass)=[xylose(g)+arabinose(g)+galactose(g)+mannose(g)]∗mbiomass(g)-1C-5(g/gbiomass)=[xylose(g)+arabinose(g)+galactose(g)+mannose(g)]∗mbiomass(g)-1equation(2)C-5(g/ghemicellulose)=[xylose(g)+arabinose(g)+galactose(g)+mannose(g)]∗[mbiomass(g)∗Xhemibiomass]-1C-5(g/ghemicellulose)=[xylose(g)+arabinose(g)+galactose(g)+mannose(g)]∗[mbiomass(g)∗Xhemibiomass]-1equation(3)C-6(g/gbiomass)=[glucose(g)+fructose(g)+cellobiose(g)]∗mbiomass(g)-1C-6(g/gbiomass)=[glucose(g)+fructose(g)+cellobiose(g)]∗mbiomass(g)-1equation(4)C-6(g/gcellulose)=[glucose(g)+fructose(g)+cellobiose(g)]∗[mbiomass(g)∗Xcellulosebiomass]-1C-6(g/gcellulose)=[glucose(g)+fructose(g)+cellobiose(g)]∗[mbiomass(g)∗Xcellulosebiomass]-1equation(5)Derived-products(g/gbiomass)=[glyceraldehyde(g)+pyruvaldehyde(g)+lactic-acid(g)+formic-acid(g)+acrylic-acid(g)+5-hydroxymethylfurfural(g)]∗mbiomass(g)-1Derived-products(g/gbiomass)=[glyceraldehyde(g)+pyruvaldehyde(g)+lactic-acid(g)+formic-acid(g)+acrylic-acid(g)+5-hydroxymethylfurfural(g)]∗mbiomass(g)-1
