Summary: Fungi, especially the edible white button mushroom, have the ability to degrade lignin and utilize it for growth. By analyzing the mycelial growth of Agaricus bisporus, researchers found that the mushroom is capable of extensive lignin degradation and identified the specific changes in lignin structure during this process. This study provides valuable insights into the mechanisms of fungal lignin conversion and contributes to our understanding of lignin decomposition.

Summary: The study found that using two or more steps of enzymatic hydrolysis can reduce the ball milling time to achieve similar carbohydrate removal while avoiding excessive decrease in lignin molecular weight. The recalcitrance towards increased enzyme hydrolysis activity by ball milling was different for the four representative biomasses, with the highest difficulty coming from walnut shells. Overall, there is a clear synergy between enzymatic treatment and ball milling efficiency to isolate lignin with high yield, high native linkage content, purity, and minimal MW reduction.

Summary: Pyrolysis liquids are difficult to analyze comprehensively due to their complex and heterogeneous composition. The use of two-dimensional 1H-13C heteronuclear single-quantum correlation (HSQC) nuclear magnetic resonance (NMR) has gained renewed interest for quantitative recording, providing a valuable tool for fingerprinting and assessing these complex liquids. However, data analysis of 1H-13C HSQC spectra has been lacking behind recent experimental developments. This study explores and demonstrates a new approach for automated data analysis from 1H-13C HSQC spectra using image processing tools.

Summary: This study investigated the role of hydrogen gas in the reductive catalytic fractionation (RCF) of wheat straw biomass. It was found that hydrogen gas can enhance lignin depolymerization and increase the yield of phenolic monomers. In the presence of hydrogen gas, the yield of phenolic monomers increased from approximately 12 wt% to 25 wt% of acid-insoluble lignin in the initial biomass. Additionally, using ethanol as a hydrogen-donor solvent resulted in the highest yield of monophenolic compounds.

Summary: Maleic acid hydrotropic fractionation (MAHF) is a selective method for fractionating wheat straw, dissolving lignin and hemicelluloses to produce cellulose-rich solids that can be used for fiber production and enzymatic saccharification. The residual lignin within the solids can be carboxylated through MAHF to aid in bleaching and nanofibrillation processes. MAHF also has the advantage of being FDA-approved as a food additive and less corrosive and more recoverable than other acids traditionally used for cellulosic fractionation.

Summary: The wheat straw was pretreated using ball milling with the assistance of solid particles, such as NaOH, NaCl, and citric acid. Among these particles, NaOH showed the best synergistic effect, leading to a decrease in straw crystallinity and particle size. After enzymatic hydrolysis, the glucose yield increased significantly. The pretreatment washing liquor was also recycled for re-treatment of partially pretreated biomass, resulting in a high glucose yield.

Summary: Phenoxyethanol (EPH) was used to create a biphasic solvent system for lignin extraction from lignocellulosic biomass. The concentration of EPH was studied to determine the pre-treatment condition for lignin fractionation. The lignin from rice straw was then fractionated using a 70% aqueous EPH solvent system, resulting in the regeneration of lignin with varying purities using different precipitants. The compositional and structural characteristics of the regenerated lignin were also analyzed.

Summary: Mild hydrothermal pretreatment coupled with solvent extraction shows promise for enhancing lignin and carbohydrate output during lignocellulose fractionation. This study compared the coupling effect of mild hydrothermal pretreatment with acidic choline chloride-natural acid or alkaline choline hydroxide based deep eutectic solvents (DES) for wheat straw fractionation. The results showed that the alkaline DES achieved better lignin removal and swelling of lignocellulose, resulting in a cellulose-rich fraction with higher potential for further processing.

Summary: Lignin nanoparticles containing essential oils from thyme species were tested as biocides against white-rot and brown-rot fungi. The essential oils showed lower minimum inhibitory concentrations against brown-rot fungi and similar concentrations against white-rot fungi compared to free essential oils. Optimization of lignin nanoparticles as essential oils delivery vehicles is required for their efficacy against white-rot fungi.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
