Summary: The study demonstrates that pretreatment using ethylene glycol and dilute sulfuric acid for lignocellulose fractionation is a simple, efficient, and promising process for corn stover biorefinery. Delignification and cellulose retention rates are high, leading to a significant increase in enzymatic hydrolysis sugar yield compared to untreated corn stover. The regenerated lignin can also be utilized to produce renewable aromatic chemicals and alkane fuels.

Summary: This study investigates the potential of using targeted pretreatments in the feedstock supply chain to enhance lignin degradation in lignocellulosic biomass. The results show that inoculating corn stover with lignin degrading fungi and storing it under simulated storage conditions can lead to degradation of hemicellulose and lignin, resulting in sugar degradation products. Lowering the reaction temperature in the pretreatment process can achieve equivalent xylose release in both stored and fungal treated samples.

Summary: A simple ethylenediamine (EDA)/urea pretreatment method at low temperature was constructed to improve enzymatic hydrolysis of corn stover. The EDA/urea pretreatment increased the concentration of reducing sugar and sugar yield compared to NaOH and EDA alone pretreatment. Scanning electron microscopy (SEM) analysis showed that EDA/urea pretreatment promoted the formation of scaly structures and holes on the surface, resulting in more disorderly biomass surface and severely damaged structure. This work demonstrated that EDA/urea pretreatment efficiently deconstructed the dense structure of lignocellulose at low temperature, showing its potential for application in bioenergy production. Evaluation: 9 out of 10.

Summary: The deacetylation process in lignocellulosic biomass pretreatment can be made more efficient and economically favorable with a flow-through diffuser type reactor and a washing step before deacetylation. Understanding the fundamentals of flow through a compressible packed bed is crucial for scaling up the process. Modifying the classical Kozeny Carman equation and developing a compressible packed bed model can accurately predict pressure-drop and stabilize the bed from extensive compression.

Summary: Predicting enzymatic saccharification yield based on biomass-water interaction measurements offers advantages for process optimization and control, but the predictive powers are low when comparing different types of biomasses. The correlation between water retention value (WRV) and enzymatic saccharification yield (ESY) is highly dependent on pretreatment chemistry, indicating a complex interplay between recalcitrance and biomass-water interactions.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
