“…They observed that the use of maleic acid promotes a minimum conversion of glucose into furfural and 5-hydroxymethylfurfural when compared to H2SO4 and this leads to less inhibition during the subsequent enzymatic hydrolysis treatment of the solid residue obtained. LIN et al (2023) performed pre-treatment with PH: AA in the ratio 8:2 (v/v) followed by treatment with 2% AA at 170 ºC for 30 min and observed the presence of 3.2% of solubilized glycan and 51.6 % of solid recovered in this treatment. Pretreatment of BCA and rice husk before subjecting to enzymatic hydrolysis with crude enzymatic extract, rich in laccase in the removal of lignin in the presence of HBT, DMP and HBA resulted in glucose release at 3.86 mg/g and 3.20 mg/g, respectively, indicating greater exposure of cellulose and hemicellulose fibers for subsequent enzymatic hydrolysis treatment (MATEI, et al, 2020).…”

“…(Figure 1). In fact, recovery of 80.3% of solids, with solubilization of 0.5% of glycan, was obtained in the pre-treatment of Alamo with a solution of hydrogen peroxide (PH) and acetic acid (AA) in a ratio of 8: 2 (v/v) in the presence of 100 mM H2SO4 at 60 ºC for 2h (LIN, et al, 2023). Pre-treatment of BCA at 15% (m/v) solids load with diluted acid/alkali and sequentially provided greater solids recovery by 83% with excellent elimination of lignin and hemicellulose present in the biomass (HEMANSI; SAINI, 2023).…”

Pretreatment and enzymatic hydrolysis are two important steps within the process of converting lignocellulosic biomass into glucose. In this work, sugarcane bagasse (BCA) ground into particles smaller than 40 mesh (< 425 µm) was pre-treated with hydrochloric acid (HCl) in different concentrations (0.75, 1.0 and 1.25 mol/L), in time varying from 30 to 90 min by autoclaving (121 ºC / 1 atm) in solid ratio :net 1:10. The pretreated BCA was subjected to hydrolysis with commercial enzymes at a solid:liquid ratio of 1:30, with100 µL of cellulase mixtures and 100 µL of Aspergilus niger laccase, in citrate-phosphate buffer (50 mM; pH 4.8) for 72h at 50 ºC under agitation at 150 rpm. Pre-treatment with HCl showed an efficiency in delignification of BCA of 59.2% and the glycan fraction increased to 64.48% in the solid residue of BCA recovered after pretreatment carried out with HCl 1.25 mol/L, time 30 min. Within these operational parameters, enzymatic hydrolysis continued for 72h. Within a mass balance analysis, a solids recovery of 42.8% was observed for the pre-treatment stage with HCl. Therefore, for every 100 g of pre-treated BCA, within the process, residue with 64.48 g of glycan and 9.23 g of lignin was recovered and for every 100 g of BCA recovered after pre-treatment and enzymatically treated with cellulases and laccase it was possible to obtain 12.0g of glycan hydrolyzed into glucose. It is concluded that pre-treatment with dilute acid and hydrolysis with commercial enzymes showed efficiency in converting BCA glycan into glucose.

“…Therefore, the lowest concentration of glucose (1.32 g/L) can be observed in the treatment with peracetic acid at a concentration of 5%, 50 ºC for 24h, presenting a significant difference between the other experiments. LIN et al (2023) performed pre-treatment with PH:AA in the ratio 8:2 (v/v) followed by treatment with 2% AA at 170 ºC for 30 min and observed the presence of 3.2% of solubilized glycan and 51.6 % of solid recovered in this treatment.…”

“…In fact, the more cellulose and hemicellulose remaining in the pretreatment residue, the greater the ethanol yield per mass of BCA.

Pretreatment and enzymatic hydrolysis are two important steps within the process of converting lignocellulosic biomass into glucose. Sugarcane bagasse (BCA) ground into particles smaller than 40 mesh was pre-treated with peracetic acid (APA) at concentrations of 5, 10 and 15% (v/v), in a time of 6 to 24h and temperature of 50 and 90 ºC in a solid:liquid ratio of 1:10. The pretreated BCA was subjected to hydrolysis with commercial enzymes in a solid:liquid ratio of 1:30, with 100 µL of cellulase mixtures and 100µL of Aspergilus niger laccase (807 U/g), in citrate-phosphate buffer (50 mM; pH 4.8) for 72h at 50 ºC under agitation at 150 rpm. The results of pre-treatment with APA showed an efficiency in the delignification of BCA of 71.1% and the glycan fraction increased from 44.78% to 53.06% in the solid residue of BCA recovered after pre-treatment carried out with APA 15 %, time of 24 hours at 50 ºC. Within a mass balance analysis, a solids recovery of 66.9% was observed for the pre-treatment stage with APA. Therefore, for every 100 g of pre-treated BCA, within the process, residue with 53.06g of glycan and 6.5g of lignin was recovered and for every 100g of BCA recovered after pre-treatment and enzymatically treated, it was possible obtain 56.88g of glycan hydrolyzed into glucose. Within these results, it is possible to conclude that acid pretreatment with APA and hydrolysis with commercial enzymes proved to be very efficient in converting glycan into glucose.
