Summary: Long-term usage of thiamethoxam has posed a serious threat to non-target organisms and ecological security. In this study, a novel polyvinyl alcohol/sodium alginate/biochar bead was used for immobilizing a high-efficiency thiamethoxam-degrading bacterium, Chryseobacterium sp H5. The results showed that the immobilized microbes in the PVA/SA/biochar beads exhibited significantly higher removal and biodegradation rates of thiamethoxam compared to other immobilization methods. Additionally, the PVA/SA/biochar beads showed increased tolerance to extreme conditions. This work suggests the potential of the PVA/SA/biochar beads for effective bioremediation of thiamethoxam contamination.

Summary: The study focuses on the optimization of crude oil degradation using bacterial and fungal co-culture with cell immobilization techniques. The results show that the co-culture with a bacterial-fungal ratio of 3:1 achieved the highest degradation efficiency and surface tension reduction. Enzyme analysis reveals that catalase played a significant role in the degradation process. The high expression of specific genes correlated with the removal of target compounds. Overall, the application of immobilized bacterial and fungal cells in defined coculture systems proves to be an effective strategy for enhanced biodegradation of petroleum hydrocarbons in aquatic systems.

Summary: This study investigated the enhanced biodegradation of oil-contaminated soil by immobilizing microorganisms with corn cob biochar. The results showed that corn cob biochar with a particle size of 0.08 mm and an immobilization time of 18 hours was the most effective carrier for immobilizing microorganisms. The immobilized microorganisms exhibited high biodegradability under stress from high concentrations of petroleum pollutants, heavy metals, and organic pollutants. In addition, the oxygen-containing groups on the surface of biochar were found to be involved in the complexation of heavy metals, which contributed to the immobilization mechanism. The biodegradable efficiency of oil by immobilized microorganisms in soil was 70.10% within 60 days, significantly higher than that of free microorganisms, and was positively correlated with the activities of catalase, urease, and polyphenol oxidase.

Summary: This study evaluated the feasibility of using Pseudomonas stutzeri immobilized sawdust biochar (PSDB) for Ni2+ removal. The results showed that PSDB had an 83% removal efficiency for Ni2+ and could be reused up to three times. The study also revealed that the mechanism of Ni2+ removal by PSDB was the synergistic effect of adsorption by biochar and bioaccumulation by P. stutzeri. This study presents a novel approach for utilizing waste biomass-derived biochar as a carrier support for bacteria and an adsorbent for pollutants.

Summary: This study investigated the effect of photo-aged polystyrene microplastics (MPs) on microbial dechlorination of polychlorinated biphenyls (PCBs). The results showed that photo-aging increased the proportion of oxygen-containing groups in MPs and enhanced their inhibitory effect on microbial reductive dechlorination of PCBs. Furthermore, MPs altered the microbial community structure and interactions, leading to increased competition among bacteria. This study provides theoretical guidance for the in situ application of PCB bioremediation technology in the presence of MPs.

Summary: Multiple studies have shown that the accumulation of microplastics/nanoplastics in the environment can lead to various problems. However, the effects of these particles on microbial communities and biogeochemical processes, especially methane metabolism, are not well understood. This study conducted a microcosm experiment to expose the particles for 120 days and found that the addition of nanoparticles had a significant adverse effect on bacterial diversity. The presence of nanoparticles also reduced microbial network complexity compared to microplastics.

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.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
