Summary: The discovery of heterotrophic nitrification-aerobic denitrification (HN-AD) microorganisms has opened up new possibilities for wastewater treatment. In this study, a new HN-AD microorganism, Pannonibacter sp. W30, was isolated and characterized. It showed high efficiency in aerobic inorganic nitrogen transformation and primarily depleted nitrogen through assimilation rather than denitrification. Compared to known Alphaproteobacterial HN-AD microbes, Pannonibacter sp. W30 had the potential to develop a suitable HN-AD technology for treating N-laden wastewater at a full-scale level.

Summary: With the rapid development of intensive aquaculture, the release of nitrogenous organic compounds has become a serious threat to aquatic organisms. In this study, aerobic denitrifying bacteria (ADB) were enriched from shrimp pond water and sediment samples using different shaking durations. The abundance and community structure of total bacteria and ADB were significantly altered under different shaking durations. The order Pseudomonadales, possessing both nosZ and napA genes, was enriched in both water and sediment samples under different shaking/static cycles.

Summary: In recent years, addressing nitrogen and phosphorus pollution in domestic wastewater has become urgent. This study focused on the use of Pseudomonas sp. Y1 as the target strain, which was immobilized using polyvinyl alcohol (PVA) matrix coupled with bentonite and lanthanum (La) to construct bioreactors. The optimal operating parameters, dephosphorization mechanism, and effects of hydrogel materials and different loads on bioreactor performance were analyzed. The study found that specific conditions resulted in the highest removal efficiencies of calcium, phosphate, and ammonium. The addition of bentonite promoted nitrification and denitrification, while the presence of La enhanced dephosphorization. High-throughput sequencing revealed the dominant presence of Pseudomonas in the bioreactor, and the expression of nitrogen removal-related functional genes was favored under specific conditions. This study highlights the superiority of microbial induced calcium precipitation (MICP) combined with PVA hydrogel and provides insights into simultaneous nitrogen and phosphate removal from wastewater.

Summary: European marine waters are heavily polluted with plastic, with an average density of one plastic item per four square meters. Limited research has been conducted on the ingestion of microplastics and nanoplastics by wild decapods in European waters, especially the European spiny lobster. Our study extracted a total of 4102 plastic particles from the stomach tissues of male and female lobsters, with only 4.8% of the 63 samples analyzed found to be free of plastic particles. The presence of microplastics was also detected in gill tissues, with a range of 11 to 339 microplastics detected per individual.

Summary: This study investigated the effectiveness of photocatalysis in purifying hospital wastewater, and found that it can effectively remove pharmaceutical residues and pathogenic bacteria, as well as alter the antibiotic resistance of surviving bacteria. However, considerable concentrations of antibiotic-resistant genes were still present in the effluents, which may contribute to antibiotic resistance in aquatic bacterial communities.

Summary: Pyrolysis of lemon stalks at 850 degrees C under limited oxygen produces highly active and selective biochar that can activate persulfate ion and oxidize sulfamethoxazole (SMX). The biochar consists mainly of carbon and oxygen atoms, with calcium and potassium as the most abundant minerals. It has a moderate specific surface area of 154 m(2) g(-1) and contains carbonate species, possibly in the form of calcium carbonate. In ultrapure water, complete degradation of 0.5 mg L-1 SMX can be achieved within 20 minutes using 500 mg L-1 sodium persulfate (SPS) and 100 mg L-1 biochar. The biochar remains stable for at least five cycles and shows potential as a sustainable, metal-free catalyst.

Summary: Human-induced climate change, with increased atmospheric CO2 concentration and sea-surface temperature, has poorly understood synergistic effects on bacterial communities in vulnerable oligotrophic marine ecosystems. In an experiment simulating future changes in surface waters of the eastern Mediterranean, we observed taxonomic differences in bacterial communities, driven by the combined effects of time and treatment. The acidification had a persistent impact on community composition, while warming benefited certain bacterial clades immediately.

Summary: In this study, valorized biomass was pyrolyzed and activated with potassium hydroxide to produce a biochar with a high specific surface area and significant amounts of surface oxygen species and carbonates. The activated biochar was used as an activator for sodium persulfate to induce the adsorption and oxidation of sulfamethoxazole in various water matrices. The degradation of sulfamethoxazole followed a pseudofirst order kinetic law, and the oxidation mechanism involved radical pathways and/or electron transfer.

The durability of plastics in the marine environment and the threshold point for the generation of secondary microplastics are still unknown. This study investigated the interaction between environmental parameters and the physicochemical properties of PE and PP films, finding a strong correlation between molecular weight and the generation of microplastics. Additionally, a significant relationship between CI and Feret diameter was identified for PP films weathered on beach sand.

The experimental work shows that activated persulfate is effective in deionized water for inactivating three types of bacteria, but ineffective in other matrices. On the other hand, UVC radiation is highly efficient against all bacteria in all matrices. The complexity of the matrix plays a significant role in the efficiency of water treatment processes.

Summary: This study found that Tamarix smyrnensis and Nerium oleander, two salt-tolerant plants, have a strong ability to accumulate Sb(III), thus they can effectively remove Sb from aqueous solutions. Although the higher concentration of Sb (10 ppm) significantly affected the chlorophyll content in Nerium oleander, it didn't have a significant impact on plant growth and water content during the experimental period. Additionally, the study also found that the roots of both plants are more prone to accumulating Sb.

Summary: A mechanistic state-space model was developed to describe the dynamics of olive mill wastewater (OMW) treatment with pomegranate and myrtle plants, and to assess the contribution of the plants in the overall remediation process. The model considers phytodegradation, rhizodegradation, accumulation of organic matter on plant roots, microbial growth and decay, and enzymatic decomposition. The model predicts that phytoremediation processes contribute over 91% to the removal of OMW organics and nutrients, regardless of the wastewater organic strength.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
