Summary: In this study, a molecularly imprinted polymer (EMIP) with selective adsorption ability was prepared to remove erythromycin (ERY) at environmentally relevant concentration. EMIP showed a large specific surface area, small pore size, and hydrophobic surface. The adsorption capacity of EMIP increased from 211.08 to 4015.51 μg/g with increasing ERY concentration from 5.00 to 100.00 μg/L. The imprinting factor for ERY was 2.57, indicating good adsorption selectivity of EMIP in the presence of interferences. Molecular dynamic simulation results showed a high adsorption energy between ERY and EMIP, favoring ERY removal. This study provides new insights for trace antibiotic removal by molecular imprinting polymers in different aqueous environments.

Summary: The design of molecularly imprinted polymers (MIPs) for specific binding of hydrophobic molecules was investigated in this study. The results showed that the most hydrophobic monomer provided the highest selective adsorption, but the non-selective adsorption and softness of poly(lauryl methacrylate) had a negative impact on selectivity. The adsorption process was exothermic and had fast kinetics.

Summary: This study aimed to prepare an ion-imprinted polymer (IIP) called IIP-Cu, using copper sulfate as a template and potassium persulfate as an initiator, and tested its effectiveness in selectively adsorbing copper ions (Cu2+) and strontium ions (Sr2+) from aqueous solutions. Various characterizations confirmed the successful removal of the template, revealing a rough and porous topology of the IIP-Cu. The adsorption of Cu2+ onto IIP-Cu was best explained using Langmuir models, with a maximum adsorption capacity of 159 mg/g. Furthermore, the efficiency of the prepared IIP-Cu was tested in real brine water, showing promising results in removing Cu2+ and competing ions.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: This study implemented a microaerobic-aerobic configuration in a full-scale municipal wastewater treatment facility and investigated the effects on sludge characteristics, pollutant removal, microbial community, and granulation mechanisms. The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: Efficient anaerobic digestion relies on the cooperation of different microorganisms with different metabolic pathways. This study investigated the effects of different operational modes and the addition of powdered activated carbon (PAC) on ethanol metabolic pathways. The results showed that the SBR mode and the presence of CO2 facilitated ethanol metabolism towards propionate production, while the CFR mode with extended solids retention time enriched Geobacter. Adjusting operational modes and PAC addition can modulate anaerobic ethanol metabolism and enrich Geobacter.

Summary: This study analyzed the occurrence and distribution of antibiotic resistance genes (ARGs) in different environmental media of the Yangtze River using metagenomics. Core resistome dominated by multidrug resistance genes was found in all samples, while rare resistome dominated by various resistance genes was more prevalent in plasmids. Specific bacteria were identified as hosts for both core and rare resistomes, with high clinical concern ARGs found in the rare resistome. Particle-associated environment provided the most ideal conditions for resistome hosts. This study provided insights into the genetic locations of ARGs and the community assembly mechanisms of ARG hosts in freshwater environments.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
