Summary: The roller experiments revealed that nano-silver could dose-dependently suppress the formation and aggregation of marine snow particles, resulting in thinner and more compact particles. Additionally, nano-silver altered the species composition and functional profile of the microbial community, inhibiting the growth of most abundant species and key biological processes. This strong microbial inhibition contributed to the suppression of marine snow formation, particularly by reducing the genes related to extracellular polymeric substance synthesis and secretion.

Summary: This work fully characterizes the extracellular polymeric substances (EPS) secreted by marine fungus and studies the corrosion behavior and mechanism of aluminum alloy caused by EPS. Approximately sixty species of proteins, nine monosaccharides, and seven organic acids have been identified. Electrochemical measurements show that EPS accelerates the corrosion of aluminum alloy, thereby promoting the formation of corrosion pits. However, the formation of a complete EPS film on the specimen surface reduces the acceleration of corrosion.

Summary: Crude oil, a highly complex mixture containing toxic compounds, can become more toxic after weathering due to changes in composition. This study found that different weathering processes altered the composition of crude oil, resulting in an increase in its toxicity. Specifically, an increase in the fraction of high molecular weight polycyclic aromatic hydrocarbons (PAHs) was identified as a main factor contributing to the increased toxicity. These findings can be used to estimate the extent of weathering and toxicity of crude oil after spills.

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: Multispecies biofilms in marine environment pose a threat to marine-based industries, and the efficacy of biocides used against these biofilms is compromised due to microbial chemical tolerance. However, the understanding of species and extracellular polymeric substances (EPS) composition in marine biofilms is limited, hindering the development of effective and environmentally friendly biocides. This study investigates the composition of EPS and population dynamics in marine biofilms developed on steel. Results show that extracellular DNA (eDNA) is a critical structural component of the biofilms, and the biofilms exhibit stable and well-defined communities with distinct EPS profiles.

Summary: Recent studies in a riparian wetland in South Carolina, USA, showed strong seasonal fluctuations in groundwater radioiodine (I-129) concentrations, with higher concentrations in summer than in winter. These fluctuations were observed only in the wetlands and only with I-129, not with other contaminants. The study proposed a hypothesis that the fluctuations were a result of coupled processes involving hydrology, water temperature, microbiology, and chemistry. The findings underscore the importance of understanding the seasonal variations of contaminants for effective long-term monitoring programs in wetlands.

Summary: The widespread presence of microplastics in global oceans raises concerns about their negative impacts on ecosystems. Understanding the mechanistic transport of microplastics is crucial for evaluating their fate and ecological risks. This study suggests a three-step process for microplastic transfer between air and sea phases, involving the incorporation of microplastics into gel aggregates, accumulation of plastic-gel aggregates on the water surface, and ejection of aggregates when trapped air bubbles burst. The composition of water, such as salinity and gel concentration, can modulate the aggregation and transport of microplastics. This research provides valuable insights into the fate of microplastics in the ocean and their transport at air-sea interfaces.

Summary: The aquaculture industry in Taiwan has a annual revenue of over USD 1.1 billion, but it also causes environmental issues such as waste discharge and groundwater withdrawals. A study in Kaohsiung, Taiwan, tested small-scale mobile cage tanks for shrimp and grouper rearing nearshore, and the results showed that the shrimp and groupers reared in these tanks had higher levels of free amino acids and were more palatable. The proposed system not only reduces the risk of eutrophication, but also has the potential for recreational fishing activities to increase income for smallholders.
