Abstract

Ball milling is used for size reduction of biomass for isolating lignin. However, it is known that it can lead to some structural alteration of lignin. Fibrillation using ultrafriction grinding is a newer size reduction technology which was applied to poplar for isolating cellulolytic enzyme lignin. Compositional analysis of poplar, enzymatic hydrolysis yield, water retention value, lignin yield, lignin structural characterization, and lignin molecular weight analysis were carried out to compare lignin isolated from fibrillated and ball milled poplar. By using fibrillation instead of planetary ball milling for size reduction of poplar, higher β-O-4' linkage content, lignin yield, and molecular weight were obtained. Replacing ball milling with fibrillation for size reduction allows recovery of lignin whose structure is closer to that of lignin in biomass.

Effect of lignin content on changes occurring in poplar cellulose ultrastructure during dilute acid pretreatment

Journal Article Sun, Qining ; Foston, Marcus ; Meng, Xianzhi ; ... - Biotechnology for Biofuels

Obtaining a better understanding of the complex mechanisms occurring during lignocellulosic deconstruction is critical to the continued growth of renewable biofuel production. A key step in bioethanol production is thermochemical pretreatment to reduce plant cell wall recalcitrance for downstream processes. Previous studies of dilute acid pretreatment (DAP) have shown significant changes in cellulose ultrastructure that occur during pretreatment, but there is still a substantial knowledge gap with respect to the influence of lignin on these cellulose ultrastructural changes. This study was designed to assess how the presence of lignin influences DAP-induced changes in cellulose ultrastructure, which might ultimately have largemore »« less

Nucleophilic Thiols Reductively Cleave Ether Linkages in Lignin Model Polymers and Lignin

Journal Article Klinger, Grace E. ; Zhou, Yuting ; Foote, Juliet A. ; ... - ChemSusChem

Lignin may serve as a renewable feedstock for the production of chemicals and fuels if mild, scalable processes for its depolymerization can be devised. The use of small organic thiols represents a bioinspired strategy to cleave the β–O–4 bond, the most common linkage in lignin. In the present study, synthetic β–O–4 linked polymers were treated with organic thiols, yielding up to 90 % cleaved monomer products. Lignin extracted from poplar was also treated with organic thiols resulting in molecular weight reductions as high as 65 % (Mn) in oxidized lignin. Thiol–based cleavage of other lignin linkages was also explored inmore »« less

Investigation of a Lignin-Based Deep Eutectic Solvent Using p-Hydroxybenzoic Acid for Efficient Woody Biomass Conversion

Journal Article Wang, Yunxuan ; Meng, Xianzhi ; Jeong, Keunhong ; ... - ACS Sustainable Chemistry & Engineering

Deep eutectic solvents (DESs) are effective solvents for biomass conversion and have been proposed as alternatives to ionic liquids (ILs). In this paper, we first report an effective pretreatment of woody biomass using a novel hardwood lignin-based DES prepared from p-hydroxybenzoic acid (PB) and choline chloride (ChCl), which are used as the hydrogen bond donor and acceptor, respectively. The impacts of the ChCl-PB DES on structural properties and enzymatic hydrolysis of poplar wood were comprehensively evaluated. The performance of ChCl-PB DES was also compared with two other DESs with p-coumaric acid (PCA) and 4-hydroxybenzaldehyde (PHA) as the hydrogen bond donors,more »« less

Characterization and analysis of the molecular weight of lignin for biorefining studies

Journal Article Tolbert, Allison ; Akinosho, Hannah ; Khunsupat, Ratayakorn ; ... - Biofuels, Bioproducts & Biorefining

The molecular weight of lignin is a fundamental property that infl uences the recalcitrance of biomass and the valorization of lignin. The determination of the molecular weight of lignin in native biomass is dependent on the bioresources used and the isolation and purifi cation procedures employed. The three most commonly employed isolation methods are milled wood lignin (MWL), cellulolytic enzyme lignin (CEL), and enzymatic mild acidolysis lignin (EMAL). Common characterization techniques for determining the molecular weight of lignin will be addressed, with an emphasis on gel permeation chromatography (GPC). This review also examines the mechanisms behind several biological, physical, andmore »« less

Structural Transformation of Isolated Poplar and Switchgrass Lignins from Dilute Acid Pretreatment

Journal Article Sun, Qining ; Pu, Yunqiao ; Meng, Xianzhi ; ... - ACS Sustainable Chemistry & Engineering

A key step in conversion of cellulosic biomass into sustainable fuels and chemicals is thermochemical pretreatment to reduce plant cell wall recalcitrance. Obtaining an improved understanding of the fundamental chemistry of lignin, the most recalcitrant component of biomass, during pretreatment is critical to the continued development of renewable biofuel production. To examine the intrinsic chemistry of lignin during dilute acid pretreatment (DAP), lignin was isolated from poplar and switchgrass using a cellulolytic enzyme system and then treated under DAP conditions. These results highlight that lignin is subjected to depolymerization reactions within the first 2 min of dilute acid pretreatment andmore »« less
