Summary: DLCA(sa) pretreatment is a low temperature and densification method for lignocellulosic biomass, which demonstrates high efficiency. This study systematically investigated the effects of temperature, acid loading, and time on the hydrolysis of xylan, cellulose, and lignin during DLCA(sa) pretreatment. It was shown that DLCA(sa) pretreatment can effectively solubilize xylan under mild conditions and a mathematical model based on xylan hydrolytic kinetics was proposed to predict enzymatic hydrolysis. The kinetic model suggested that mechanical densification facilitates the penetration of acid into the biomass matrix, increasing the accessibility of xylan to acid catalysis.

Summary: Lignocellulose, consisting of cellulose, hemicellulose, and lignin, has great potential as a renewable resource for sustainable chemical and fuel production. Efficient pretreatment strategies are needed to unlock its full potential. This comprehensive review surveys the latest developments in polyoxometalates (POMs)-assisted pretreatment and conversion of lignocellulosic biomass, highlighting the significant increase in glucose yield and improved cellulose digestibility achieved through the synergistic effect of ionic liquids (ILs) and POMs. Successful integration of POMs with deep eutectic solvents (DES) or γ-valerolactone/water (GVL/water) systems for lignin removal is also discussed, offering avenues for advanced biomass utilization.

Summary: Hydrothermal pretreatment is an effective method to improve the saccharification of lignocellulose. In this study, an efficient hydrothermal pretreatment of sunflower straw was conducted, resulting in the removal of 58.8% xylan and 33.5% lignin at a treatment temperature of 180 degrees C for 120 min and a solid-to-liquid ratio of 1:15. Various characterizations confirmed that hydrothermal pretreatment altered the surface structure and increased the accessibility to cellulase. The enzymatic saccharification of the treated sunflower straw achieved a high yield of reducing sugar and glucose and also produced xylo-oligosaccharide in the filtrate.

Summary: This article reviews and advances the enhanced in-situ reductive dechlorination of chloroethenes, polychlorinated biphenyls, and chloroethenes. Reductive dechlorination is an important pathway for degradation of chlorinated hydrocarbons in anaerobic environments. Functional anaerobic bacteria are widely used biotic remediation technologies, but when natural electron acceptors compete with contaminants for electrons, it can be problematic. A thorough mechanistic overview of electron competition and selectivity is critical for accurately evaluating the effectiveness of this technology.
