Sep 25, 2018 · For marine archaea, it has been shown that both rare and abundant members of the community were re-occurring seasonally and that different ecotypes of archaea had different seasonal patterns [20, 25].
Jul 23, 2019 · Only 1% of marine bacteria can be grown in a laboratory. So scientists have to study them in the ocean. The tiny size of bacteria makes this very hard. Scientists sometimes collect microbes using plankton nets. These cone-shaped nets have a very fine mesh. A container at one end of the net collects the samples.
Marine food web. The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as ...
Marine life, sea life, or ocean life is the plants, animals, and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms, mostly microorganisms, produce oxygen and sequester carbon.
Marine microbes are abundant and diverse. But their tiny size means they are not easy to study. First observed in 1675, marine microbes were not cultured in the lab for over 100 years allowing for further observation. Molecular advances and large DNA libraries allowed for many advances since the 1970s and there is still much to learn!
Jul 7, 2020 · Ammonia-oxidizing archaea (AOA) are among the most abundant and ubiquitous microorganisms in the ocean, exerting primary control on nitrification and nitrogen oxides emission. Although united by a ...
Alkanes are saturated apolar hydrocarbons that range from their simplest form, methane, to high-molecular-weight compounds. Although alkanes were once considered biologically recalcitrant under anaerobic conditions, microbiological investigations have now identified several microbial taxa that can anaerobically degrade alkanes. Here we review recent discoveries in the anaerobic oxidation of ...
