Summary: This study investigates the water purification performance of laccase immobilized graphene oxide (Lac-GO) and explores the mechanism of enzyme-enhanced adsorption. The results show that laccase immobilization does not affect the adsorption behavior of graphene oxide, but the enzyme-enhanced adsorption process exhibits higher adsorption capacity and rate due to the enzymatic degradation of adsorbed micro-pollutants. Furthermore, the study reveals a clear synergy mechanism between adsorption and enzymatic degradation, leading to improved micro-pollutant removal.

Summary: In this study, the Laccase enzyme was immobilized on an inert support and doped with copper to enhance the chlorophenol inactivation kinetics under light and dark conditions. The stability and effectiveness of the resulting Lac@Cu-H-TiO2 compound were demonstrated, as it efficiently degraded 2,4-dichlorophenol under visible light and maintained stability for multiple cycles. These findings suggest that photo-active enzyme integrated photocatalysts have great potential for phenolic pollutant degradation.

Summary: This study demonstrates that the addition of 4-chlorophenol significantly inhibits the ammonia-nitrogen removal efficiency and the activity of anammox process at different concentrations. Metagenomic analysis reveals a decrease in the abundance of KEGG pathways associated with carbohydrate and amino acid metabolism with increasing 4-chlorophenol concentration. The presence of 4-chlorophenol enhances the decomposition of extracellular polymeric substances (EPS) and bacterial debris, and partially converts 4-chlorophenol to p-nitrophenol.

Summary: In this study, various N'-substituted benzylidene benzohydrazide-1,2,3-triazoles were designed, synthesized, and evaluated for their inhibitory activity against alpha-glucosidase. The structures of the derivatives were confirmed using multiple spectroscopic techniques. All derivatives exhibited potent inhibition, with IC50 values ranging from 0.01 to 648.90 μM, compared to acarbose as the positive control (IC50 = 752.10 μM). Compounds 7a and 7h showed significant potency, with IC50 values of 0.02 and 0.01 μM, respectively. Further studies revealed that these compounds are noncompetitive inhibitors of alpha-glucosidase. Fluorescence quenching and molecular docking were also used to investigate the interaction and binding mechanisms between the inhibitors and the target enzyme.
