A polymer deposition-mediated surface-charge reformation strategy: reversing the MOF biomineralization behavior.

Biomineralization of a porous metal-organic framework (MOF) shell onto biomacromolecule templates is a burgeoning strategy to construct robust biocatalysts. However, it strongly relies on the interfacial interaction between MOF precursors and enzyme surface, significantly limiting the generalization of this nanotechnology. Herein, we identify polymers that are well-suited for deposition onto target biomacromolecules supramolecular interactions and introduce a polymer deposition-mediated surface-charge reformation strategy to facilitate the biomineralization of porous MOFs, including ZIF-8, ZIF-90, and ZIF-zni onto enzymes.

A positive contribution to nitrogen removal by a novel NOB in a full-scale duck wastewater treatment system.

Nitrite-oxidizing bacteria (NOB) are undesirable in the anaerobic ammonium oxidation (anammox)-driven nitrogen removal technologies in the modern wastewater treatment plants (WWTPs). Diverse strategies have been developed to suppress NOB based on their physiological properties that we have understood. But our knowledge of the diversity and mechanisms employed by NOB for survival in the modern WWTPs remains limited.

Effects of triclosan adsorption on intestinal toxicity and resistance gene expression in Xenopus tropicalis with different particle sizes of polystyrene.

Microplastics (MPs) are commonly found with hydrophobic contaminants in the water column and pose a serious threat to aquatic organisms. The effects of polystyrene microplastics of different particle sizes on the accumulation of triclosan in the gut of Xenopus tropicalis, its toxic effects, and the transmission of resistance genes were evaluated. The results showed that co-exposure to polystyrene (PS-MPs) adsorbed with triclosan (TCS) caused the accumulation of triclosan in the intestine with the following accumulation capacity: TCS + 5 µm PS group > TCS group > TCS + 20 µm PS group > TCS + 0.
