Summary: A multicolor visual method based on a magnetic immunoassay and enzyme-induced gold nanobipyramids etching was developed for the detection of deoxynivalenol (DON). The method showed a linear relationship between the shift of local surface plasmon resonance (LSPR) and the DON concentration. The recovery for naturally contaminated wheat and maize was satisfactory, and the proposed method has the potential for on-site rapid screening of mycotoxins in grain. However, there is a need for a breakthrough in the simultaneous detection of multiple mycotoxins using the current multicolor visual method.

Summary: Low Fe(II) generation is the main limitation for Fenton process, and providing electrons is the solution to promote Fe(III) reduction. This study systematically reviewed the strategies for enhancing Fe(III)/Fe(II) cycle based on electron donors, which can be classified into five categories: e-PF, e-EF, e-Re, e-Ox, and e-TC. The principles and mechanisms of each enhanced Fenton process were clarified, and the role of chelate agents and carbon-based materials were discussed. Among them, e-Re showed the best performance in pollutant degradation, making it the most promising approach. The development of reductants for future practical application is necessary.

Summary: This study proposes a simplified method to enhance microbial nitrate reduction to ammonia (NRA) by using zero-valent iron (ZVI) as an augment. The method promotes the NRA process through both direct and mediated electron transfer pathways from ZVI to bacteria, as well as the complementation between biological and abiotic nitrogen conversion. The bio-hybrid shows significantly improved NO3- reduction activity, nearly 100% NRA selectivity, and good stability for wastewater treatment.

Summary: Previous studies focused on direct interactions of plastics with microorganisms, but ignored their ecotoxicity effects on the dissemination of antibiotic resistance genes (ARGs). This study reveals that environmentally relevant concentrations of phthalates (PAEs) significantly enhance the transfer of ARGs among environmental microorganisms. The interaction between PAEs and cell membrane phospholipids lowers membrane fluidity and increases permeability, facilitating gene transfer. Increased levels of reactive oxygen species and overexpression of conjugation-associated genes under PAE stress also contribute to enhanced gene transfer. This study provides important insights into the environmental risks of plastics and the control of ARG spreading.

Summary: Clarifying the reaction pathways at the solid-water interface and in bulk water solution is crucial for designing heterogeneous catalysts for selective oxidation of organic pollutants. In this study, the origin of organic oxidation reactions with metal oxide catalysts is unraveled, showing that radical-based advanced oxidation processes prevail in bulk water but not on solid catalyst surfaces. These findings provide a fundamental understanding of catalytic organic oxidation processes at the solid-water interface and can guide the design of heterogeneous nanocatalysts.

Summary: This study investigates the dynamics of nitrogen removal and antibiotic resistance genes (ARGs) between Shortcut nitrification-denitrification (SCND) and full nitrification-denitrification (FND) processes under long-term selective pressure conditions. The results show that the SCND process exhibits higher extracellular polymers, respiratory activity, TN removal performance, and impact resistance compared to the FND process. Furthermore, the SCND process maintains a lower abundance of total ARGs and shows better inhibition effect on potential pathogenic bacteria proliferation.

Summary: In this study, it was found that natural polyphenols can assist in the activation of peracetic acid by conveniently obtained Fe(III), leading to efficient removal of bisphenol A. Hydroxyl radicals (center dot OH) are the main contributors to BPA degradation, with superoxide radicals (O2 center dot-) functioning as intermediates. The reaction intermediates between polyphenols and reactive oxygen species play a crucial role in the regeneration of Fe(II) and enhanced activation of peracetic acid.
