Carbon fixation in marine ecosystems is a vital process that contributes to climate regulation, with ocean sediments playing a critical role in carbon sequestration. This process is driven by chemolit...
Although nitrogen fixation has recently been recognized in the Arctic Ocean, the biogeographical patterns of diazotrophs in this region remain poorly resolved, leaving a critical gap in understanding ...
By tracking the water mass histories of genetic samples, we investigated the biophysical dynamics shaping eukaryotic phytoplankton populations in a nutrient-deplete subtropical gyre, where cyanobacter...
Trace elements occur naturally in the environment, but anthropogenic activities can amplify their release, increasing exposure and bioaccumulation in marine predators such as seabirds. Mercury (Hg) in...
Cystic fibrosis (CF)-associated lung infections caused by Pseudomonas aeruginosa (P. aeruginosa) and Staphylococcus aureus (S. aureus) remain difficult to treat due to multidrug resistance and the red...
Microbially-derived polyketides include some of today's most valuable medicines, yet their discovery has focused on a narrow subset of Earth's microbial biodiversity. Although understudied biomes such...
Antibiotic resistance genes (ARGs) have drawn global attention and are ubiquitously detected in marine environments. Seamounts, prominent seafloor features with high biodiversity, may be hotspots for ...
Many materials create new habitats for microbial colonization and the persistence of potentially pathogenic bacteria. Despite this, comparative studies addressing the microbial diversity and pathogeni...
Anaerobic oxidation of methane (AOM) mediated by archaea is a pivotal process for methane consumption in gas seepage-associated sediments. Despite its importance in regulating methane flux, the ecolog...
Bacteria are a major component of deep-sea communities. Mesoscale changes were observed in the deep western Mediterranean by analysing deposited DNA in four sediment cores from SE Barcelona, at 1050 m...
Anthropogenic disturbances increasingly compromise marine environments, with severe consequences for vulnerable coral ecosystems. While global stressor impacts on stony corals are well-documented, the...
Numerous studies have shown that microbial metabolites, which represent the products of bacteria in the human gut, play a key role in shaping cancer risk and response to treatment. However, metabolite...
The marine dissolved organic matter (DOM) pool is one of Earth's largest carbon reservoirs and a critical regulator of global carbon flux, yet the microbe-molecule interactions governing it remain lar...
Marine microorganisms are vital to biogeochemical cycles and food web dynamics, with their community structure shaped by environmental factors such as temperature, light, and salinity. While microbial...
Antimicrobial resistance studies have focused on clinical bacteria, neglecting the role of resistant isolates in natural environments. However, oceans are daily contaminated with high loads of antimic...
Sponges are important members of shallow-water, benthic ecosystems, where they often rely on their microbial symbionts to acquire organic or inorganic carbon. Sponges are also found in the deep sea, h...
Dimethylsulfoniopropionate (DMSP) is one of the most important organic sulfur compounds in the ocean and plays a key role in polar carbon and sulfur cycles. Sulfitobacter sp. M13, a Gram-negative and ...
Antarctica's remote wilderness is increasingly impacted by human activities such as tourism, scientific research, and historical and contemporary exploitation of marine resources. Despite regulatory m...
Shewanella sp. FeAMO (=MCCC M27737) and Shewanella sp. JL219SE-S6 (=MCCC M29292) were isolated from hydrothermal sediments from Wocan-1 hydrothermal field (6°22'N, 60°32'E, at a depth of 2995 m) and T...
