Summary: In this study, the community structure and function of denitrifying and anammox microorganisms in the sediments of the Yangtze Estuary and its adjacent sea were analyzed using high-throughput sequencing, qPCR, and isotope techniques. The results showed that denitrification was the dominant contributor to nitrogen removal processes, and sediment Chla was a key factor regulating the rates of denitrification and anammox.

Summary: Coastal marine lagoons are highly vulnerable to anthropogenic pressures, and sediment microorganisms play a crucial role in mitigating these impacts. This study investigated the microbial communities in the sediment of Mar Menor, a lagoon in Spain heavily impacted by human activities. The results revealed high heterogeneity in microbial communities among different stations, but a core microbiome was identified. Factors such as sediment texture, presence of specific vegetation, depth, and geographic location influenced the microbial assemblages. Additionally, heavily contaminated stations had less stable microbial communities compared to non-contaminated stations, suggesting the presence of specialized bacteria sensitive to change.

Summary: Plastics accumulate in the polluted Mediterranean Sea, forming the plastisphere. The composition of microbial community on plastic is influenced by the sampling site and polymer chemical composition. Enrichment cultures show the presence of plastic-degrading microorganisms with potential role in plastic degradation.

Summary: The study examined the diversity and polymer degradation potential of epiphytic bacteria associated with different marine macroalgae. It identified 238 strains belonging to various classes and clustered into 45 genera, with potential novel taxa identified. These bacteria exhibited significant polymer hydrolysis potential, indicating their potential for bio-remediation of agro-waste based raw materials and their potential use in green technology.

Summary: Microbes in the marine environment are widely distributed and most of them have not yet been cultured. Drying treatments can alter the cultivated microbial diversity, and some potential novel species can only be cultured from drying-treated samples. Drying treatments have different effects on different genera, and they play a significant role in the separation of microbial communities at a cultivation temperature of 28 degrees Celsius.

Summary: Coastal systems such as estuaries are facing threats from multiple anthropogenic stressors worldwide, yet the relationship between these stressors, estuarine hydrology, and benthic bacterial communities remains poorly understood. This study in Sydney Harbour, Australia, found that sediment bacterial communities varied significantly in response to proximity to storm drains, with differences in gene expression patterns indicating potential tolerance to localised anthropogenic stressors. Overall, the research sheds light on changes in the composition and functioning of benthic bacterial communities in different hydrological conditions under the influence of various human pressures.

Summary: Research on microbial communities in sediment cores from an anchialine sinkhole in the Bahamas suggests that the source of organic matter deposited in the sediment over time influences the composition of subsurface microbial communities. This indicates that carbon source is a key driver of microbial community composition in anoxic sediment, with implications for understanding carbon cycling in coastal sedimentary basins.

Summary: The study revealed that illumination reduction not only facilitated the growth of nirS denitrifying and anammox bacteria in the rhizosphere, but also weakened the competition between the two bacteria.

Summary: A novel bacterium, named Sneathiella sedimenti, was isolated from coastal sediment in the Republic of Korea. It is a Gram-negative, rod-shaped, and motile bacterium that grows best at 30 degrees Celsius, pH 7.0, and with 1.0% NaCl.

Summary: This study analyzed the coverage of 16S rRNA gene primers used in oral microbiome studies and identified the best primers. The findings showed that the optimal primers can be utilized for detecting both oral bacteria and archaea, with a wide coverage range.

Summary: This study examines the relationship between microbial community dynamics and DMS concentrations in an oceanographic time series conducted on the east Australian coast. The results show that seasonal shifts in microbial community composition affect the net DMSP concentrations, with certain phytoplankton species producing more DMSP than others. Additionally, planktonic bacteria play a significant role in producing DMSP and DMSO in ocean surface waters.

Summary: The study assessed midgut bacteria of field-collected and laboratory-reared larvae and adults of Aedes aegypti and Ae. albopictus from Sri Lanka. The data confirm that midgut bacterial diversity in the studied mosquitoes varies according to species, developmental stage, and strain (field vs laboratory).

Summary: Evaluation of the microbial identity, diversity, and community structure in the Nile River revealed that microbial communities were primarily influenced by sample type (sediment versus water) rather than seasonal or spatial factors. The presence of potential pathogens and toxin-producing cyanobacteria in low abundance was identified within the Nile microbiome. Functionally, antibiotic biosynthesis and aerobic xenobiotic degradation pathways were predicted in the river microbiome.

Summary: The study reveals that bacteria and archaea in the Clarion-Clipperton Zone demonstrate previously undetected subtle regional-scale biogeography. Variability between regions is driven mainly by differences in the relative abundances of taxa rather than by abundant taxon turnover.
