Summary: In this study, a collection of 209 gut phages for 42 commensal human gut bacterial species was presented and analyzed. Genome analysis revealed 34 previously undescribed genera of phages. The study also identified two phages from a candidate family, Paboviridae, that were highly prevalent in the human gut. Infection assays demonstrated the specificity of Bacteroides and Parabacteroides phages to bacterial species, as well as substantial variations in phage susceptibility among strains of the same species. Furthermore, a cocktail of 8 phages effectively reduced the abundance of Bacteroides fragilis strains in vitro. This study expands the diversity of cultured human gut bacterial phages and provides a valuable resource for human microbiome engineering.

Summary: This work proposes a new and environmentally friendly sample preparation strategy called "in-syringe-assisted fast pesticides extraction (FaPEx)" technique coupled with LC-MS/MS for the rapid identification and monitoring of fipronil and its metabolite fipronil sulfone in chicken egg and environmental soil samples. The FaPEx strategy involves two simple steps: extraction using low-volume acetonitrile with NaCl and anhydrous MgSO4 salts, followed by solid-phase extraction (SPE) using cleanup sorbents and salt combinations for the cleanup process. The developed method shows excellent linearity, precision, and recovery, making it suitable for the analysis of fipronil and its metabolites in food and environmental samples.

Summary: This study evaluates the conditions for assessing the biochemical methane potential of spent coffee grounds as a substrate, and finds that a substrate-to-inoculum ratio of 2 is not suitable for bio-CH4 production. Pretreatment with dilute acid and thermal has the potential to increase bio-CH4 yield, with significant effects observed for pretreatment time, acid concentration, and liquid-to-solid ratio. Fourier-transform infrared spectroscopy shows that major functional groups are still present in the coffee grounds after pretreatment.

Summary: The green chemical and enzymatic pretreatments play a crucial role in dealing with the recalcitrant nature of lignocellulosic biomasses. Traditional pretreatments only partially degrade lignin and hemicellulose in the biomass, limiting enzyme accessibility and lignin-enzyme interaction. Hybrid enzymatic pretreatments, involving special chemical treatments and lignin sulfonation techniques, enhance lignin modification, hemicellulose solubilization, saccharification, and fermentation processes. This article discusses recent developments in various chemical and hybrid enzymatic pretreatments and highlights the challenges and potential solutions for industrial application in lignocellulosic biorefineries.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
