Summary: This paper systematically reviews and discusses the effect of ozonation on the removal of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in aqueous solutions. The results show that ozonation is more effective in removing resistant bacteria than their respective genes, but there is no definite conclusion about the superiority of ozone alone or in a hybrid form. The study also evaluates the regrowth after ozonation and the influence of operational parameters on degradation efficiency.

Summary: The electro-peroxone (EP) process is an electricity-based oxidation process that generates hydrogen peroxide (H2O2) from cathodic oxygen (O2) reduction to remove antibiotic resistant bacteria (ARB) and plasmid-encoded antibiotic resistance genes (ARGs). Compared to ozonation alone, the EP process exhibits higher center dot OH exposures but lower O3 exposures, resulting in a moderately decreased efficiency of ARB inactivation and ARG degradation. However, the EP process effectively cleaves plasmid DNA to shorter fragments, reducing the risks of natural transformation of ARGs. Consideration of the effects of the EP process on ARB and ARG inactivation is important for water treatment implementation.

Summary: Microplastic particles (MPs) are prevalent pollutants in aquatic ecosystems, with a significant number reaching open waters and potentially contributing to the spread of pathogenic bacteria and antibiotic resistance genes. Studies have shown that the bacterial community on MPs differs from planktonic bacteria in treated wastewater, with potentially pathogenic bacteria showing higher abundances in the latter. However, only the sul2 resistance gene was found to be more abundant in the plastisphere compared to the planktonic bacterial community.

Summary: This study investigated the microbial effects of electrolytic mixed oxidants (EMO) treatment on influent seawater samples in fish farms. The results showed that EMO treatment significantly reduced the number of culturable prokaryotes and had a greater effect on prokaryotes compared to eukaryotes. The microbiome analysis revealed changes in microbial diversity after treatment, with a notable decrease in Bacteroidia and an increase in Campylobacteria in prokaryotes. Additionally, plant and phytoplankton cells were more susceptible to EMO treatment than zooplankton.

Summary: Bacterial adaptation to external stress and its evolution to antibiotic resistance poses a risk to the health sector. Conventional wastewater treatment may disseminate antibiotic resistance, but new technologies are emerging. This study found that stress-adapted bacteria survived SPC treatment for a longer time compared to unadapted bacteria.

Summary: Improving the quality of treated wastewater is crucial in water-stressed regions. This study explores the potential of using a diverse bacterial community to prevent the overgrowth of harmful bacteria in ozone treated wastewater during storage. The results show that the diluted samples with the added bacterial community had diverse bacterial composition and did not show an increase in antibiotic resistance genes.

Summary: The study investigated the degradation kinetics of antibiotic resistance genes using different disinfectants, revealing varied degradation mechanisms for different types of ARGs. Furthermore, differences in degradation rates for extracellular and intracellular ARGs were observed at different oxidant exposures, possibly due to decreased DNA recovery efficiency and/or the presence of MRSA aggregates protected from disinfectants.

Summary: In this study, it was found that erythrosine (ERY), an edible dye, can efficiently degrade intracellular antibiotic resistance genes (iARGs) by generating abundant O-1(2) under visible light. The degradation of 6 log iARGs was achieved within 40 minutes. The unique indirect oxidation of iARGs induced by O-1(2) resulted in a 3.2-fold faster degradation of intracellular ARGs compared to extracellular ARGs. Additionally, other photosensitizers with high O-1(2) yields, such as Rose Bengal and Phloxine B, also demonstrated efficient iARG degradation.

Summary: The study found that hybrid chlorine and UV disinfection treatment was more effective in microbial diversity and antibiotic resistant genes in treated sewage compared to single disinfection treatments. All disinfectants used resulted in increased abundance of antibiotic resistant genes. Hybrid disinfection treatment was the most effective method in alleviating the risks associated with the reuse of treated sewage.

Summary: The study investigated the inactivation kinetics of multidrug-resistant bacteria in wastewater by the emerging environmentally-friendly disinfectant peracetic acid (PAA), showing that the inactivation was governed by exposure time and concentration integral. Soluble constituents in wastewater decreased PAA inactivation effectiveness, and chlorine showed higher inactivation of resistant bacteria compared to PAA.

Summary: Tetracycline has been detected in various environments, leading to the development of resistance in bacterial populations. This study fabricated soybean straw biochars (SSBs) at different pyrolysis temperatures and used them as activators for the degradation of tetracycline and disinfection of tetracycline-resistant Escherichia coli. The results showed that the purification effect of SSBs depended on the pyrolysis temperature, with SSB1000/PS system exhibiting superior degradation and disinfection capabilities. The purification mechanisms of tetracycline and Escherichia coli were found to be different, with tetracycline degradation mainly relying on surface-bound radicals and bactericidal activity attributed to free SO4 center dot- in bulk solutions. The catalytic performance of SSB1000 was attributed to its unique characteristics, such as large mesopore volumes, high C=O content, low interfacial charge transfer resistance, and strong electron donating capacity.

Summary: The study found that UV/PAA-H disinfection was most effective for removing tetracyclines, quinolones, macrolides, and beta-lactams, while NaClO disinfection was effective for removing sulfonamides. The majority of ARGs were well removed after UV/PAA-H disinfection, but specific genes increased after NaClO disinfection. The highly reactive oxidation species generated from the UV/PAA process were responsible for the elimination of antibiotics and ARGs.

Summary: This study investigated the ecotoxicological effects of acute exposure to microplastics (MPs) at environmentally relevant concentrations on the metabolome and gut microbiota of zebrafish. The findings from metabolomics and gut microbiota analysis revealed alterations in metabolites, dysbiosis of gut microbiota, and oxidative stress in zebrafish exposed to MPs. The study suggests that MPs could disrupt the metabolic interaction via the microbiota-gut-liver-brain relationship, leading to gastrointestinal and neurological/immune disorders in zebrafish.
