Summary: This study systematically investigated the transformation kinetics and pathways of Sulfamonomethoxine (SMM) by UV/H2O2 in swine wastewater. The degradation of SMM in real wastewater was found to be lower than in synthetic wastewater due to the presence of conventional contaminants. Different factors, such as H2O2 dosage, pH conditions, and the presence of carbonate and nitrate, were found to influence the degradation of SMM in the UV/H2O2 system.

Summary: In this study, a three-dimensional (3D) blocky CoMoO4@CMS composite was fabricated by anchoring the ready-made CoMoO4 catalyst on the skeleton surface of the chitosan coated melamine sponge (CMS), which exhibited excellent catalysis and reusability in the activation of peroxymonosulfate (PMS) for the degradation of sulfadimethoxine (SDM) in water. The CoMoO4@CMS/PMS system showed over 98% degradation of SDM within 10 minutes and achieved acceptable recyclability in continuous five rounds. The system also demonstrated strong anti-interference ability in actual lake water matrix.

Summary: Long-term exposure to low levels of antibiotics leads to the accumulation of antibiotics in the environment and organisms, inducing the formation of antibiotic resistance genes. Seawater, as an important sink for contaminants, was used to degrade tetracyclines at environmentally relevant levels using laccase from Aspergillus sp. and mediators. The enzymatic structure of laccase was affected by the high salinity and alkaline of seawater, resulting in reduced affinity to the substrate. However, the laccase-SA system was able to completely degrade tetracyclines within 2 hours, demonstrating its potential for pollutant elimination in the marine environment.

Summary: The study demonstrated that anaerobic digestion can effectively remove SDM when added at concentrations observed in on-farm manure, without compromising energy production. The reductions in TC and SDM concentrations did not consistently correlate with decreases in specific gene copies, and high concentrations of antibiotics could affect methane production.

Summary: This study investigated the biotransformation of sulfamonomethoxine (SMM) in an aerobic granular sludge system. The results showed that biodegradation played a more important role than adsorption, and the tightly bound extracellular polymeric substances (TB-EPS) on microbial cells had higher adsorption capacity. Spectroscopic analysis revealed that SMM could interact with EPS through various compounds. Batch tests showed that hydroxylamine and hydroxylamine oxidoreductase (HAO) were effective in the biotransformation of SMM. UPLC-QTOF-MS analysis identified five major transformation pathways. The study contributes to a better understanding of SMM biotransformation.

Summary: The experimental solubility of sulfamonomethoxine in various solvents showed differences, with acetone having the highest solubility. The solubility in ethyl acetate was not significantly affected by temperature changes, and in acetone + water mixture solvents, solubility increased with temperature and acetone concentration. Thermodynamic equations were used to correlate solubility data and obtain thermodynamic properties of the dissolution process.

Summary: The circadian clock is a specialized cell signaling pathway present in all cells, crucial for cell, tissue, and organism health. Changes in the chondrocyte circadian clock in osteoarthritis can lead to disease development. Environmental factors such as mechanical loading, diet, inflammation, and oxidative insult can influence clock function, potentially contributing to alterations in the chondrocyte clock in osteoarthritis.

Summary: In this study, a spherical solid biocatalyst, Lac@Ce-GMA-Cu-DA@AS, was prepared by co-immobilizing laccase and acetosyringone mediator in a functionalized cellulose composite doped with HKUST-1. The Lac@Ce-GMA-Cu-DA@AS microbeads showed higher catalytic activity, better reusability, and superior degradation efficiency for the substrate compared to the undoped HKUST-1. This research provides a practical new approach for the degradation of polycyclic aromatic hydrocarbon pollutants in water.

Summary: Double refractory gold ore, which contains a higher level of gold than general ore, has been overlooked in industry due to economic reasons. However, the degradation of carbonaceous matter in double refractory gold ore by enzymatic reactions using laccase and 1-hydroxybenzotriazole hydrate (HBT) as an electron mediator has shown promising results in improving gold extraction. In this study, the multiple-divided additions of the laccase-mediator system (LMS) were performed to maintain enzyme activity, resulting in a significant improvement in gold extraction compared to single additions. The optimized total dose of laccase was found to be 11.87 U/100 mL, resulting in an 86.1% gold extraction rate from pretreated double refractory gold ore with a C content of 5.2%. These findings highlight the potential of the LMS approach and its importance in understanding carbon science in hydrometallurgy.

Summary: This study introduces a computational method to design a new aptamer with higher binding affinity to a specific target using step by step mutation based on MD simulation. The designed mutant aptamer, M5, showed significantly improved specificity towards SDM compared to the native aptamer, as indicated by the large difference in Delta G(Bind) values. The selectivity of the M5 aptamer towards SDM was confirmed through MD simulation, validating its potential for further experimental studies.

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.
