Summary: This study compared and discussed the promotion effect of hydrogen peroxide (H2O2) in Fe(VI) and Fe(VI)-H2O2 processes, revealing that the Fe(VI)-H2O2 system exhibited better oxidation performance due to the catalytic role of H2O2. Additionally, the system showed satisfactory pollutant removal effects in real water conditions.

Summary: Ethanol solution is widely used as a disinfectant, but only has significant bactericidal capability at a volume fraction of around 70%-75%. Higher concentrations are irritating while lower concentrations are less effective. This study proposes a plasma-activated low-concentration ethanol solution (PAES) as a green, efficient and less irritating disinfectant.

Summary: Peracetic acid (PAA) can be used for pre-oxidation and mussel control in drinking water treatment. The reaction mechanisms between PAA and chlorine have not been fully studied, but it is found that the molar stoichiometric ratio of PAA to free chlorine is approximately 2:1, and the reaction rate coefficients vary with pH. A kinetic model was developed based on these values to predict the chlorine demand by PAA.

Summary: A novel photoelectrochemical process (PEC/E-H2O2) was adopted to improve disinfection efficiency in distributed water treatment systems using clean energy. The process consumed low energy and effectively eliminated E. coli under simulated solar conditions. The in-situ generated H2O2 enhanced the oxidation of the photoelectrochemical system and resulted in a higher inactivation rate of E. coli compared to traditional methods. The study provides a promising alternative disinfection process for drinking water treatment.

Summary: The authors report a porphyrin-based photocatalyst that can efficiently synthesize H2O2 from water and oxygen. The catalyst achieves a quantum efficiency of 14.9% at 420 nm and 1.1% at 940 nm, and a solar-to-chemical conversion efficiency of 1.2% under simulated sunlight. Photogenerated electrons and holes contribute to H2O2 production through different active sites.

Summary: This study demonstrates that boric acid acts as a catalyst for hydrolysis of peroxyacids, significantly increasing the hydrolysis rate. The reaction is pH-dependent, with maximum rates at pH 9 for peracetic acid and pH 8.4 for 3-chloroperbenzoic acid. The presence of ethylenediaminetetraacetic acid (EDTA) and ethylenediamine tetramethylene phosphonic acid (EDTMP) is necessary to prevent metal ion interference. The catalytic mechanism involves boric acid acting as a Lewis acid catalyst, reducing the leaving group basicity in the transition state.

Summary: Peracetic acid is widely used as a disinfectant in water treatment due to its effectiveness and ease of use. However, its chemical behavior is still debated. This study found that peracetic acid itself can contribute to the formation of potentially carcinogenic compounds, in addition to its ability to form halogenated byproducts in the presence of organic matter and halides.

Summary: A concise, transition-metal and protection-free synthesis of adagrasib (MRTX849), a novel KRASG12C inhibitor drug, was achieved using two sequential SNAr reactions to introduce chiral building blocks to the tetrahydropyridopyrimidine core. Extensive reaction optimization led to a robust, transition-metal-free oxidation of the sulfide intermediate. The use of a suitable leaving group at the 4-OH position facilitated a facile SNAr displacement to introduce the chiral piperazine, resulting in a five-step, chromatography-free synthesis with improved efficiency.

Summary: This study assessed the effectiveness of seven products on phytoplankton and zooplankton biomass in aquaculture systems. Copper-based products remain the most efficient and cheapest choice to reduce total phytoplankton biomass, while peracetic acid-based products effectively and quickly reduce cyanobacteria with marginal effects on beneficial algae and zooplankton. Such algaecides could be effective alternatives to copper-based products for aquaculture farmers.

Summary: A multiple stage anaerobic system was proven effective for reductive decolorization of azo dyes in the presence of sulfate. The system achieved significant bulk color removal and organic matter and sulfate reduction in separate reactors. By utilizing amplicon sequencing and correlation analysis, the microbial communities and pathways involved in azo dye removal were identified, with reductive decolorization being mainly associated with hydrogen-producing pathways and the involvement of an azoreductase from Lactococcus lactis. The findings enhance our understanding of the role of different microbial communities in anaerobic treatment of azo dyes and can aid in the design of improved solutions for textile effluent treatment.

Summary: The enzymatic processes involved in the degradation of the artificial sweetener acesulfame (ACE) in municipal wastewater treatment have been poorly understood. In this study, two bacterial taxa, an unknown Chelatococcus species and Ensifer adhaerens, were enriched from activated sludge using ACE as the carbon source, and cell-free lysates were analyzed to demonstrate enzymatically catalyzed ACE degradation. The fractionation of the lysate succeeded in separating the enzymes responsible for the initial transformation of ACE and further transformation pathway, providing evidence that the cleavage of the sulfuric ester moiety of ACE is the initial step. The analysis of the unfractionated lysate revealed proteins possibly involved in ACE transformation, including a highly abundant amidase and an ABC transporter substrate-binding protein.

Summary: Enriching the living environment of captive fish can improve their welfare, but studies on the feasibility of implementation in real farming scenarios are limited. This study tested the feasibility of using plastic shelters to improve rainbow trout welfare in an organic fish farm. The shelters had no negative effects on fish performance, health, or mortality, but there were no clear shelter-seeking behavioral responses from the fish when disturbed. It is recommended to test enrichment strategies in real scenarios for a relevant part of the fish's life cycle to fully understand their potential for improving welfare in aquaculture.

Summary: Sea trout is a popular recreational angling target species in the Baltic Sea region and beyond. Information about the postrelease impacts of catch and release (C&R) on survival and growth in saline waters is largely missing. This study investigated the impacts on survival and growth of angled and released sea trout in a flow-through seawater raceway, and found that adverse effects of C&R on coastal sea trout may not pose a significant problem for sea trout stocks.

Summary: Synthetic plastics, such as PET, are widely used but pose a major threat due to their environmental persistence. The bacterium I. sakaiensis has been discovered to solely thrive on degrading PET films and its monomers. By analyzing protein expression, it was revealed that PET and its monomers induce the MHETase and affect two major pathways: the TCA cycle and the beta-oxidation pathway. The increased expression of proteins involved in these pathways suggests their importance in the degradation process.

Summary: This study examined a full-scale membrane bioreactor (MBR) with ultrafiltration and granular activated carbon (GAC) for the potential reuse of treated water as drinking water or for irrigation. The MBR removed most of the bacteria, while the GAC removed a significant amount of organic micropollutants. Seasonal variations in inflow and infiltration resulted in concentrated influent during summer and diluted influent in winter. The effluent concentrations of E. coli met irrigation water standards but exceeded drinking water standards in Sweden.

Summary: The recent development of ancient DNA sequencing techniques has provided valuable insights into previous civilizations, but their full potential has not yet been realized. In this study, researchers extracted ancient DNA from a 2900-year-old clay brick from the palace of King Ashurnasirpal II in Nimrud, Iraq. They identified 34 unique taxonomic groups of plants, making the pioneering discovery that ancient DNA can be effectively protected and successfully extracted from well-preserved clay. Future research in this area has significant scientific prospects and could lead to a deeper understanding of ancient and lost civilizations.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
