Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled Marine ...
International Census of Marine Microbes. The International Census of Marine Microbes is a field project of the Census of Marine Life that inventories microbial diversity by cataloging all known diversity of single-cell organisms including bacteria, Archaea, Protista, and associated viruses, exploring and discovering unknown microbial diversity ...

A microorganism (or microbe) is any microscopic living organism, that is, any life form too small for the n
An archaeal virus is a virus that infects and replicates in archaea, a domain of unicellular, prokaryotic organisms. Archaeal viruses, like their hosts, are found worldwide, including in extreme environments inhospitable to most life such as acidic hot springs, highly saline bodies of water, and at the bottom of the ocean.
Nanoarchaeum equitans is a species of marine archaea that was discovered in 2002 in a hydrothermal vent off the coast of Iceland on the Kolbeinsey Ridge by Karl Stetter. It has been proposed as the first species in a new phylum, and is the only species within the genus Nanoarchaeum. Strains of this microbe were also found on the Sub-polar Mid ...
Structure of the siderophore triacetylfusarinine encapsulating iron (III) within a tris (hydroxamate) coordination sphere (color code: red = oxygen, gray = carbon, blue = nitrogen, dark blue = iron). [1] Siderophores (Greek: "iron carrier") are small, high-affinity iron - chelating compounds that are secreted by microorganisms such as bacteria ...
Jan 30, 2024 · Chemosynthesis is a metabolic process that transfers carbon to the biosphere using reduced compounds. It is well recognised that chemosynthesis occurs in much of the ocean, but it is often thought to be a negligible process compared to photosynthesis. Here we propose that chemosynthesis is the underlying process governing primary production in much of the ocean and suggest that it extends to a ...
