Deep-sea hydrothermal vents are among the most extreme and geochemically dynamic environments on Earth, characterized by steep gradients in temperature and chemical concentration. Alvinocaridid shrimp...
Microbe-mineral interactions play a crucial role in microbial energy conservation and mineral mobilization within deep-sea hydrothermal vents, yet the specific microorganisms involved remain largely u...
It is estimated that millions of species exist in the deep-sea environment, such as hydrothermal vents, cold seeps, abyssal plains and seamounts, which have yet to be described. Non-invasive biodivers...
The deep sea contains a wealth of potential mineral resources, many of which are being investigated for commercial exploitation. Exploration and technical tests started in the late 1970s with an initi...
Iron is one of the most important elements of the Earth, yet its bioavailability is limited in oceanic environments. In this context, deep-sea hydrothermal ecosystems represent one of the major source...
In deep-sea hydrothermal vents, sulfur compounds are central for microbial bioenergetics. Despite its significant impact on the global sulfur cycle, anaerobic sulfur compound disproportionation remain...
Deep-sea hydrothermal vents and cold seeps, typical ecosystems characterized by abundant carbon but limited nitrogen, support thriving microbial activities. The source of nitrogen has long been a key ...
This study compares predicted sulphur metabolism genes across four Acidihalobacter type strains and two metagenome-assembled genomes (MAGs), revealing genomic differences that appear to correspond to ...
Marine bacteria thrive in oceanic environments and produce extracellular polysaccharides (EPSs) for cell adhesion and survival under extreme marine living conditions. Due to variations in marine extre...
Protein persulfidation, a major post-translational modification mediated by the gaseous signaling molecule hydrogen sulfide (H₂S), regulates diverse physiological processes in eukaryotes and bacteria....
Larval migration plays an essential role in determining the distribution and evolution of invertebrate animals endemic to hydrothermal vents-disjunct and ephemeral habitats in the deep sea. However, t...
Deep-sea hydrothermal vents and cold seeps sustain highly productive animal communities through chemosynthetic symbioses, among which bathymodioline mussels are prominent examples. Bathymodioline gill...
Bacterial adaptation to fluctuations in salinity includes the intracellular accumulation of organic compounds called compatible solutes (CS) such as the amino acid derivatives ectoine and 5-hydroxyect...
In the deep ocean, hydrothermal vents sustain remarkable animal-microbial symbioses, in which bacteria colonizing animal external or internal tissues use reduced chemicals from venting fluids to perfo...
Deep-sea hydrothermal vents emit geothermal light, yet its ecological role in shaping microbial adaptation remains largely unexplored. To investigate this, we designed a custom cultivation system that...
Deep-sea methane seeps host diverse and abundant animal communities, including an extensive undescribed diversity of small cryptic invertebrates. We describe a new genus and species of neomphalid snai...
We report a draft genome of Bacillus sp. isolated from deep-sea sediment from hydrothermal vents. The genome size is 4.20 Mbp with a %GC content of 43.41. Our results highlight genes related to biofil...
A facultatively anaerobic, thermophilic, Gram-negative bacterium, strain sy37T, isolated from a deep-sea hydrothermal field and belonging to the candidate phylum WOR-3, was characterized in detail. Th...
The deep sea is home to a vast and largely unexplored microbial biosphere, along with large amounts of complex organic matter (COM). However, the functional capacity of the deep-sea microbiome to meta...
The long-term resilience of the Southern Ocean ecosystem relies on healthy populations of Antarctic krill, but climate change and increasing fishing pressure are placing this species at risk. Protecti...
