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...
Global warming and the resulting surface seawater stratification have led to dominance of small phytoplankton, driving substantial changes in planktonic ecosystem structure. This study investigates th...
The ocean's aphotic interior harbors three-quarters of planktonic bacteria and archaea (prokaryoplankton), whose composition, ecology, and biotechnological potential remain poorly constrained. To addr...
The deep sea, Earth's largest yet least-explored biome, harbors vast microbial diversity. In this issue of Cell Host & Microbe, Guo et al. uncover its hidden functional potential through metagenomics ...
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...
The rare biosphere harbors immense microbial diversity, yet most low-abundance taxa remain uncultured and functionally enigmatic. Here, we isolated strain D14T from deep-sea water, and propose to clas...
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...
Chemosymbiotic bivalves play a fundamental role in deep-sea cold seep and hydrothermal vent ecosystems, where essential long-chain polyunsaturated fatty acids (LC-PUFAs) are scarce. Whether these biva...
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...
While chemosymbiosis offers deep-sea bathymodioline mussels a critical metabolic advantage, this dependence makes them vulnerable when removed from their native environment, and their early post-recov...
Here we report the microbiome composition and lipid (molecular and isotopic) profile of gills from Archivesica sp. Atacama., a new species of deep-sea bivalve family Vesicomyidae collected at 2839 m d...
Cold-water coral reefs host diverse microbial communities that play key roles in nutrient cycling and deep-sea productivity. Among them, methylotrophic bacteria metabolize and cycle one-carbon (C1) co...
Marine deep-sea environments harbour microorganisms with extraordinary biosynthetic potential, yet their secondary metabolite repertoires remain largely uncharacterised. This study reports the isolati...
