Sugarcane bagasse delignification with potassium hydroxide for enhanced enzymatic hydrolysis
The optimization of an alkaline pretreatment process for the delignification of sugarcane bagasse (SCB) to enhance the subsequent enzymatic hydrolysis was performed according to the Doehlert uniform shell design. In this experimental design, the effect of two factors—potassium hydroxide (KOH) concentration and autoclaving time at 121 C (1 atm)—on cellulose, hemicellulose, or the total polysacch...
متن کاملPretreatment Strategies for Delignification of Sugarcane Bagasse: A Review
The valorization of agro-residues by biological routes is a key technology that contributes to the development of sustainable processes and the generation of value-added products. Sugarcane bagasse is an agro-residue generated by the sugar and alcohol industry in Brazil (186 million tons per year), composed essentially of cellulose (32-44%), hemicellulose (27-32%) and lignin (19-24%). The conve...
متن کاملChemical and morphological characterization of sugarcane bagasse submitted to delignification process for enhanced enzymatic digestibility
In this work, high resolution 13 C solid-state NMR was used to obtain information on the chemical modifications taking place on sugarcane bagasse. The method consists of monitoring the change in the 13 C NMR spectra, which is characterized by a series of lines associated to the different chemical groups in the sample. The DPMAS method is probably the most quantitative 13 C NMR technique for app...
متن کاملChemical and morphological characterization of sugarcane bagasse submitted to a delignification process for enhanced enzymatic digestibility
BACKGROUND In recent years, biorefining of lignocellulosic biomass to produce multi-products such as ethanol and other biomaterials has become a dynamic research area. Pretreatment technologies that fractionate sugarcane bagasse are essential for the successful use of this feedstock in ethanol production. In this paper, we investigate modifications in the morphology and chemical composition of ...
متن کاملDelignification of Sugarcane Bagasse with Alkali and Peracetic Acid and Characterization of the Pulp
Sugarcane bagasse was delignified with alkali and peracetic acid in a two-stage process to obtain pulps with high yield and low kappa number. The experimental results indicated that alkali pretreatment prior to peracetic acid (PAA) delignification could significantly reduce PAA loading by partially removing lignin and swelling the fibers. An optimum condition for the two-stage delignification w...
