Summary: This study investigates the degradation kinetics of different types and conformational forms of ARGs and mobile genetic elements as a function of water matrix with UV and UV/H2O2 treatments. The results show that UV treatment is effective for degrading e-ARGs, while UV/H2O2 treatment is slower for degrading i-ARGs. The generation of radical species in wastewater can improve the degradation efficacy of UV/H2O2 treatment. Additionally, the conformational differences of plasmids also influence the rate of UV-mediated gene damage.

Summary: This study shows that bromide (Br- ) can enhance the degradation of sulfamerazine (SMR) by horseradish peroxidase (HRP), mainly through oxidation and substitution processes. The transformation pathways of SMR involve hydrolysis and breaking up of sulfonamide bond to generate small fragments, as well as demethylation, Smile rearrangement, and bromine substitution to form other products. The degradation products and bromate formed during the process do not inhibit bacteria growth, suggesting no significant environmental risk.

Summary: A novel pyrophosphate-based proton shuttle strategy is proposed to improve on-site photocatalytic H2O2 generation in alkaline waters for organic pollutant treatment. The pyrophosphate-incorporated g-C3N4 (PCN) photocatalyst shows a record-high alkaline H2O2 synthesis rate and apparent quantum yield under visible light. Mechanism study demonstrates that the pyrophosphate serves as a proton shuttle to adsorb and provide protons, and as active sites for O2 adsorption and activation to promote O2 reduction, greatly benefiting the formation of H2O2. This work provides a promising approach for preparing photocatalysts with superior alkaline H2O2 synthesis efficiency for on-site treatment of organic pollutants.

Summary: This study investigated the use of ionizing radiation to decompose partially hydrolyzed polyacrylamide (HPAM) in oilfield wastewater, reducing its viscosity. The results showed that the viscosity of HPAM solution decreased rapidly during radiation, and the decrease was minimally affected by the initial HPAM concentration and pH. The application of gamma radiation disrupted the hydrogen bonds within and between HPAM molecules, leading to the destruction of the network structure and a reduction in viscosity. Additionally, attacks on various chemical bonds in HPAM resulted in the formation of intermediate products. Overall, ionizing radiation shows promise as an alternative method for treating HPAM-containing oilfield wastewater.

Summary: This study found that ionizing radiation pretreatment of antibiotic fermentation residues (AFRs) can stimulate the production of medium chain fatty acids (MCFA) and inhibit the proliferation of antibiotic resistance genes (ARGs). The results showed that radiation at 10-50 kGy decreased the abundances of ARGs by 0.6-21.1% at the end of fermentation process. Mobile genetic elements (MGEs) exhibited higher resistance to ionizing radiation, requiring radiation over 30 kGy to suppress their proliferation. Radiation at 50 kGy achieved a sufficient inhibition of MGEs, with degradation efficiencies of 17.8-74.5% for different types of MGEs. This study suggests that ionizing radiation pretreatment could be a viable option for the safer application of AFRs by eliminating ARGs and preventing horizontal gene transfer.

Summary: This study investigated the fate of antibiotic resistance genes (ARGs) during the fermentation of antibiotic fermentation residues (AFRs) using a two-stage anaerobic fermentation process. The results showed that microbial richness increased while the total abundance of ARGs slightly decreased during the transition from acidification to chain elongation (CE). The negative correlation between ARGs and microbes also increased, suggesting the inhibitory effect of CE microbes on ARGs amplification. However, the total abundance of mobile genetic elements (MGEs) increased, indicating a potential increase in gene horizontal transfer of ARGs. This study highlights the effectiveness of two-stage anaerobic fermentation in restricting ARGs amplification, but long-term dissemination of ARGs still requires attention.
