The excessive presence of antibiotics in water is a significant social concern, as it poses serious health risks to humans, necessitating the urgent development effective removal methods. Herein, an interfacial polymerization method presented fabricate caterpillar-like covalent organic frameworks (COF) platform with branch buds (Tp-Bpy) and utilize post-modified modulate environment channels. Tp-Bpy channels grafted Cu ions ether-oxygen chains (Mae) afforded more recognition sites inner hindrance, thereby enhancing antibiotic capacity efficiency through synergistic interactions controlled analyte diffusion. Cu@Tp-Bpy-Mae exhibited significantly higher capacities (412.79-435.49 mg g-1) for four antibiotics, far surpassing those Tp-Bpy, Cu@Tp-Bpy, other documented material, due electrostatic forces, π-π interactions, coordination bonding, hydrogen bonding. More importantly, capable treating real wastewater concentrations below 0.02 L-1 under continuous flow conditions, effectively mitigating drinking caused by high levels. This study offers facile tailoring material properties optimize performance exhibits great potential environmental pollutant removal.

Metformin is one of the most prescribed antidiabetic agents worldwide and also considered for other therapeutic applications including cancer endocrine disorders. It largely unmetabolized by human enzymes its presence in environment has raised concern, with reported toxic effects on aquatic life potentially humans. We report isolation characterisation strain MD1, an aerobic methylotrophic bacterium growing metformin as sole carbon, nitrogen energy source. Strain MD1 degrades into dimethylamine used growth, guanylurea a side-product. Sequence analysis fully assembled genome showed affiliation to Aminobacter niigataensis. Differential proteomics transcriptomics, well mini-transposon mutagenesis strain, point genes proteins essential growth associated hydrolytic C-N cleavage or cellular transport guanylurea. The obtained results suggest recent evolution growth-supporting capacity degrade metformin. Our identify candidate enzymatic system transformation will inform future research fate degradation products
