Novel supramolecular deep eutectic solvent pretreatment for obtaining fluorescent lignin and promoting biomass pyrolytic saccharification. BIORESOURCE TECHNOLOGY 2023; 388:129780. [PMID: 37739185 DOI: 10.1016/j.biortech.2023.129780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 09/07/2023] [Accepted: 09/11/2023] [Indexed: 09/24/2023]
Abstract
In this study, β-CD was used as a receptor to prepare three novel SDES, which were used to pretreat corn stalks for obtaining fluorescent lignin and promoting biomass pyrolytic saccharification. It was found that GA-residue had a high cellulose retention ratio (94.63%) and the highest lignin removal ratio (61.78%). Besides, the yield of carbohydrates in bio-oil was increased from 0.63% to 49.37%, and fluorescent lignin was prepared for explosion detection, fluorescent film, and information encryption. It was confirmed that the weak interaction between β-CD and HBDs or dimer was mainly performed by hydrogen bond and van der Waals force. The minimum frontier orbital energy difference ΔEU (0.1976 a.u.) and high binding energy (-5456.71 kJ/mol) between molecules were calculated by DFT. Moreover, the mechanism of biomass pretreatment was explored. The green and efficient SDES developed in this study were of great significance for biomass pretreatment and efficient utilization of components.

BIORESOURCE TECHNOLOGY 2023; 376:128856. [PMID: 36907227 DOI: 10.1016/j.biortech.2023.128856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/04/2023] [Accepted: 03/07/2023] [Indexed: 06/18/2023]
Abstract
Enhancing the degradation of lignocellulosic structure is essential for the efficient use of corn stover. This study investigated the effects of using urea combined with steam explosion on the enzymatic hydrolysis and ethanol production of corn stover. The results demonstrated that 4.87% urea addition and 1.22 MPa steam pressure were optimal for ethanol production. The highest reducing sugar yield (350.12 mg/g) was increased by 116.42% (p < 0.05), and the corresponding degradation rates of cellulose, hemicellulose, and lignin in pretreated corn stover were increased by 40.26%, 45.89% and 53.71% compared with the untreated corn stover (p < 0.05). Moreover, the maximal sugar alcohol conversion rate was approximately 48.3%, and the ethanol yield reached 66.5%. In addition, the key functional groups in corn stover lignin under combined pretreatment were identified. These findings offer new insights into corn stover pretreatment and can help develop feasible technologies to enhance ethanol production.
