Summary: This study compared the responses of bacterial community, human pathogenic bacteria (HPB), and fecal indicator bacteria (FIB) to sludge pretreatment-anaerobic digestion (AD). The results showed that AD drove the variation of bacterial community and led to the convergence of HPB communities in pretreated sludge. FIB was found to be suitable for characterizing general pathogen removal rather than showing the real pattern of HPB. AD-related parameters played an important role in assessing pathogen inactivation.

Summary: Urban tree cover is considered an environmentally-friendly and effective approach for urban cooling, but its effectiveness is influenced by meteorological variables and varies in cities with different climates. African cities, especially arid ones, should not rely solely on increasing tree cover to alleviate heat stress, but instead consider other combined cooling strategies.

Summary: Marine and estuarine environments are often contaminated by microbiological factors, which have negative effects on their use and human health. This study compared fecal indicator bacteria (FIB) and bacterial pathogen profiles in two ecosystems in Agadir Bay over a two-year period, to investigate the impact of human activities. The study found that Vibrio target pathogens were frequently detected, while Salmonella was less prevalent. In addition, other pathogenic bacteria such as Cronobacter sakzakii, Pseudomonas fluorescens, and Aeromonas hydrophila were also identified.

Summary: CH4 emissions from landfills show temporal and spatial variation due to changing meteorological conditions. A water-heat-gas transfer model incorporating a meteorological module and CH4 oxidation was used to investigate the influence of barometric pressure, air temperature, and rainfall on CH4 transport, oxidation, and emissions in landfill cover soils. Results indicated that low atmospheric pressure can lead to lower CH4 oxidation efficiency, while rainfall events decrease CH4 emission flux. Establishing a real-time landfill CH4 emission model considering varying climatic conditions is crucial for improving prediction accuracy.

Summary: This study investigated the relationship between harmful cyanobacterial blooms in upstream reservoir and geosmin explosion events in downstream reservoirs. It found that the explosion of geosmin in the downstream reservoirs could be attributed to the transport and release of geosmin through water discharge from hydroelectric power generation. Therefore, understanding the cascade structure of reservoirs is important for water quality management of drinking water sources.

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.
