Summary: This study examined the relationships between sedimentary microplastics, biota, environmental properties, and sediment stability using variance partitioning and correlation analyses. The results showed that the presence of microplastics influences sediment stability, and microplastics appeared to mediate the effects of environmental properties and fauna on sediment stability. The study also discussed the potential for microplastics to influence biota, biostabilization processes, and mediate microplastic resuspension dynamics within estuaries.

Summary: This study investigates the relationship between microbial extracellular polymeric substances (EPS) and sediment organic carbon in mangrove ecosystems. The study finds that both EPS and EPS-C increase with mangrove zonation from seaward to landward, and are positively correlated with soil organic carbon. Additionally, the study identifies a positive linkage between EPS and specific bacterial taxa. This research highlights the importance of EPS in the carbon pool in mangrove ecosystems and provides a better understanding of the functions of mangroves in carbon stocks.

Summary: This study evaluated the changes of rFe, vFe, and RV after removing EPS, and found that TB-EPS played a crucial role in vivianite formation, contributing 28-51% of vivianite recovery and 34-55% of iron reduction. Electronic shuttle substances in TB-EPS enhanced the EET rate and efficiency between cells and Fe(III). Additionally, redox proteins were embedded in EPS, shortening the distance of electron hopping and accelerating vivianite recovery from wastewater.

Summary: This study demonstrates that EPS have a significant impact on the adsorption characteristics of sediment particles, with sediments coated with EPS showing different adsorption properties at various development stages and an increase in phosphorus adsorption capacity with EPS growth. The research also proposes a formula describing the change in adsorption isotherm parameters over time for sediment particles.

Summary: The contamination of water resources and food chain by Sb bearing tailings in abandoned antimony mines is a significant problem. Microorganisms and extracellular polymeric substances (EPS) produced by bacteria were found to play a crucial role in tailing leaching and reaction speeding. This study investigated the leaching pattern of Sb from Sb bearing tailings using Acidithiobacillus ferrooxidans and analyzed the mechanism of EPS in the leaching process of Sb. Various techniques were employed to characterize the generation behavior of EPS during bioleaching and the changes of EPS functional groups before and after leaching. The findings provide insights into the biogeochemical cycle of Sb and the reduction of risk associated with high-valent antimony.

Summary: It has been found that Saccharomyces cerevisiae transfers electrons externally to electrode surfaces through an extracellular polymeric substance network, with flavoproteins responsible for non-diffusive extracellular electron transfer. This mechanism could advance bioenergy generation through microbial fuels.

Summary: This study investigated the benefits and mechanism of using tannic acid (TA) as a conditioner for sediment dewatering. The results showed that TA effectively improved the dewatering performance of sediment by reducing protein content and enhancing particle aggregation. Using TA as an effective option for rapid dewatering of sediment was confirmed, providing a reference for choosing appropriate conditioners for sediment dewatering.

Summary: The presence of extracellular polymeric substance (EPS) affects the interfacial interaction between titanium dioxide nanoparticles (nTiO(2)) and algae, promoting surface accumulation of nanoparticles on algal cells while limiting their internalization. The different endocytosis pathways for anatase nTiO(2) and rutile nTiO(2) entering algal cells may be attributed to their affinities to mediating receptors. EPS removal activates mediating pathways, facilitating more nanoparticle internalization.

Summary: This study investigates the response of extracellular polymeric substances (EPS) in Microcystis aeruginosa to microplastics (MPs). The results show that MPs can inhibit the growth of Microcystis, but enhance the secretion of EPS. The organic composition in EPS varies differently in response to MP exposure, leading to changes in the dominant components and potential ecotoxicological risk. These findings contribute to our understanding of the interaction between phytoplankton and MPs in aquatic environments.

Summary: This study found that mangrove reforestation promoted metal accumulation in sediments, but alleviated metal bioavailability. These changes were highly correlated with EPS and microbial composition, with the content of EPS positively correlated with metal accumulation and negatively correlated with metal bioavailability.

Summary: The extracellular polymeric substances (EPS) in activated sludge play significant roles in the adsorption of nanoparticles, especially nano-silver (nano-Ag), from wastewater. This study investigated the adsorption mechanism of nano-Ag by activated sludge and the contributions of different EPS fractions. The results showed that about 26-41% of nano-Ag was trapped by the bound EPS matrix and 42.5-52.6% of them were adsorbed onto the inner cells. The interaction energy contributions of EPS fractions varied, with DEPS being negative and LB-EPS and TB-EPS being positive. EPS fractions played a significant role in adsorbing nano-Ag at low concentrations but had limited effect at high concentrations.

Summary: Seasonal physicochemical parameters at different stations along the Negro River Estuary in Argentina were studied, revealing higher total phosphorus concentration in warmer months compared to previous data, with orthophosphate values also high and fluctuating independently of total phosphorus. Turbidity, water temperature, pH, and conductivity did not seem to play a key role in phosphorus variations. An unexplained high total phosphorus spike in spring samples suggests the need for further research in the area.
