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 mediated manganese (Mn) oxidation is a key process in the biogeochemical cycling of Mn. While Shewanella is widely recognized for its metal-reducing capabilities, recent studies have shown...
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 ...
The anaerobic oxidation of methane and higher C2+ alkanes is a dominant metabolism within hydrocarbon-rich deep-sea sediments and is largely mediated by alkane-oxidizing archaea in metabolic partnersh...
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...
Benthic prokaryotic communities in deep-sea sediments remain poorly studied. They are constrained by organic matter availability and oxygenation in warm deep-sea ecosystems. Here, we investigated bent...
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...
Deep-sea hydrothermal vents are archetypal chemosynthetic ecosystems, yet the intense geothermal near-infrared (NIR) radiation emitted by black smoker chimneys remains a largely unexplored environment...
A novel Gram-stain-negative, non-flagellated, non-motile, rod-shaped bacterial strain, designated 502str34T, was isolated from deep-sea sediment. The strain was positive for oxidase, catalase and urea...
Natural products from marine and terrestrial organisms provide an important resource for medicinal chemistry and drug discovery. Defined as occurring at depths greater than 200 m, most of the ocean, b...
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...
Microorganism-mineral interaction is crucial for understanding the degradation of organic matter involved in the electron exchange in marine sediments. Widespread metal-reducing bacteria Shewanella sp...
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...
