Summary: Methanogen plays a crucial role in pollution treatment and energy recovery, but the effects of emerging pollutants (EPs) on methanogen in anaerobic digestion (AD) are not well understood. This study found that chrysene (CH) had a positive effect on the methane production in AD and the growth of methanogen. It was also discovered that CH increased the activity of acetoclastic methanogenesis (AM) and enriched the AM-associated bacteria in the AD process. Furthermore, the presence of CH upregulated the expression of key enzymes in methanogen, enhancing their performance. This study provides insights into the effects of EPs on industrially important methanogen and has implications for AD technology.

Summary: The presence of PVC microplastics at environmentally relevant levels does not affect methane production but reduces the toxicity of cadmium. When the concentration of PVC microplastics reaches 30 particles/g TS, methane production recovers to 89.7% in the presence of 5 mg Cd/g TS compared to the control. The adsorption of Cd by PVC microplastics is higher than that of sludge-substrate, reducing the bioavailability of Cd during anaerobic digestion.

Summary: This study reported a new strategy for improving anaerobic digestion (AD) performance under ammonia pressure by regulating the microbiome and enzymes to enhance volatile fatty acids (VFAs) bioconversion. The addition of glutathione significantly increased methane yield and enhanced bioconversion and cell viability under ammonia stress. Metagenomic and metaproteomic analyses revealed that key microbiota and vital proteins involved in enzyme synthesis and catalysis were enriched in the presence of glutathione. The findings suggest that glutathione plays a role in regulating functional microbiome and enzyme activity, offering an alternative approach for improving AD performance under high ammonia conditions.

Summary: The number of plastics is increasing due to the rapid development of the plastics industry. Both petroleum-based plastics and bio-based plastics generate microplastics during use, which are inevitably released into the environment and accumulated in wastewater treatment plant sludge. Anaerobic digestion, a popular sludge stabilization method, is influenced by different microplastics. This paper comprehensively reviews the impact of petroleum-based microplastics and bio-based microplastics on anaerobic digestion methane production and compares their effects on biochemical pathways, key enzyme activities, and microbial communities. It also identifies future challenges, proposes research priorities, and predicts the future development direction of the plastics industry.

Summary: The study identifies the key role of Polyamide 6 (PA6) microplastics in enhancing methane production during anaerobic digestion, with a significant increase in methane production due to the presence of caprolactam (CPL). PA6 has a less toxic effect compared to other microplastics on waste activated sludge (WAS) anaerobic digestion, and it promotes key enzyme activities leading to increased methane production potential and volatile solids destruction.

Summary: The presence of microplastics (MPs) in sludge treatment systems, particularly anaerobic digesters, can have an impact on their performance. However, pretreating the sludge with alkaline solution can increase methane yield and mitigate the negative effects of MPs. Furthermore, the surface morphology, crystallinity, and carbonyl index of PET microplastics change significantly after pretreatment and digestion, which may affect their fate and environmental impact.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
