Summary: Phosphogypsum (PG) generated during phosphoric acid production contains a significant amount of sulfate, which can be biologically converted into sulfide. This study focuses on selecting and evaluating microbial consortia from sulfate-rich environments for the initial step of sulfur recovery. The MYC-consortium isolated from a hydrothermal niche showed the highest reduction capacity and performance under various conditions. This research provides insights into the potential of the MYC-consortium in converting sulfate from PG into sulfide, which is a critical step in sulfur biorecovery.

Summary: This research investigates the use of propionate-cultured sludge to enhance methane production from upflow anaerobic sludge blanket systems (UASB) treating fresh landfill leachate. The experimental results showed that the optimal OLR for UASB 1 without augmentation was 48.2 gCOD/L dot d, achieving a CH4 production of 4019 mL/d. On the other hand, the optimal OLR for UASB 2 with propionate-cultured sludge augmentation was 12.0 gCOD/L dot d, achieving a CH4 yield of 6299 mL/d.

Summary: Our study examined the anaerobic microbial degradation of hazardous polycyclic aromatic hydrocarbons (PAHs) and found that sulfate-reducing bacteria (SRB) in contaminated freshwater sediments can effectively degrade three-ringed phenanthrene and highly recalcitrant four-ringed pyrene. Desulfovibrio was the dominant bacterium in the phenanthrene-degrading culture, while Rhodopseudomonas was a significant member in the pyrene-degrading culture. This research indicates that SRB could play a crucial role in the natural attenuation of PAHs in oxygen-depleted freshwater sediments.

Summary: The study reveals that increasing the dose volume and frequency of liquid dosing can accelerate the methane generation rate of municipal solid waste, reducing the lag time for generation. For reactors with dose volumes of 40, 80, and 160 L/Mg-MSW, increasing dose frequency results in a more pronounced increase in methane generation rate and decrease in lag time.

Summary: The USA, China, and India are the top producers of municipal solid waste, with waste composition varying based on income levels. Municipal solid waste management options include recycling, incineration, waste-to-energy conversion, composting, or landfilling. Landfilling is a preferred method globally, with critical factors for sustainability including liners, soil cover thickness, leachate collection, and gas recovery facilities. Landfills act as ecological reactors undergoing various transformations, with bioreactor landfills emerging as a next-generation solution for efficient waste stabilization through controlled recirculation.

Summary: This study compared N2O emissions from bioreactor landfills with different ventilation methods and found that continuous aeration was more favorable for the biodegradation of organic matter. Both intermittent and continuous aeration effectively removed nitrogen compounds from leachate. The denitrifying bacterial community in the landfill was influenced by the stabilization and nitrogenous compound concentrations in the waste and leachate.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. 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.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
