Here we demonstrate substantial enrichments of mercury and methylmercury, along with the presence of microbes capable of metabolizing mercury in sediments of the Haima cold seep, South China Sea, by analyzing mercury and methylmercury concentrations, mercury isotopic composition analyses and metagenomic ...

To isolate the novel bacterium, the team took sediment samples from a deep-sea cold seep, wherePlanctomycetesbacteria are known to reside, and then encouraged their growth by supplementing a standard growth medium with the antibiotic rifampicin and sources of nitrogen. They cultured these enriched ba...
In the deep-sea cold seep sediments that are impacted by darkness, low temperatures, and high hydrostatic pressure, growth of microbiomes consuming rich hydrocarbons is also supposed to be nitrogen limited. Biological nitrogen fixation is one main source of bioavailable nitrogen, offsetting localized n...
Leakages of cold, methane-rich fluids from subsurface reservoirs to the sea floor are termed cold seeps. Recent exploration of the deep sea has shed new light on the microbial communities in cold seeps. However, conventional metagenomic methods largely r
Deep sea cold seep sediments host abundant and diverse microbial populations that significantly influence biogeochemical cycles. While numerous studies have revealed their community structure and functional capabilities, little is known about genetic heterogeneity within species. Here, we examine intraspecies ...
Cold seep and hydrothermal vent system have unique function in mass circulation of the earth, and have been explored by in situ detection technologies in past decades. A brief review on the development and the newest applications of in situ laser spectroscopy for deep sea research is presented ...
The effect of seafloor cold seeps on the biogeochemical cycling of mercury (Hg) remains enigmatic. Here we demonstrate substantial enrichments of mercury and methylmercury, along with the presence of microbes capable of metabolizing mercury in sediments of the Haima cold seep, South China Sea, by ...
Lingshui Cold Seep was found to have erupted after 2019, located off Hainan Island in the South China Sea at a depth of 1700 m. This seep is characterized by typical deep-sea features, including complete darkness, high hydrostatic pressure, and high levels of reductive compounds like methane ...
