Sediments From The Deep Sea Give Insight Into Dynamics Of The Deep Biosphere
2013-10-22 14:53:38

Max Planck Institute Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years. For more a decade scientists at the Max Planck Institute for Marine Microbiology and their colleagues at MARUM and the University of Aarhus have investigated microbial life from this habitat. This "Deep Biosphere", reaching several hundred meters below the seafloor, is exclusively...

Methane Seeps Of The Deep Sea Are A Bacteria Feast For Lithodid Crabs

Helmholtz Centre for Ocean Research Kiel (GEOMAR) Photos and analyses reveal more about a highly specialized food web The bottom of the deep sea is largely deserted. Oases occur for example at cold seeps where water transports dissolved elements from the seabed: Specialized microbes convert methane and sulfate from sea water to hydrogen sulfide releasing carbon dioxide. Highly adapted bacteria, many of which live in symbiosis with worms and clams, use the hydrogen sulfide for their...

Mystery Of Marine Methane Oxidation Unraveled
2012-11-12 13:27:20

Max-Planck-Gesellschaft Researchers uncover how microorganisms on the ocean floor protect the atmosphere against methane Microbiologists and geochemists from the Max Planck Institute for Marine Microbiology, along with their colleagues from Vienna and Mainz, show that marine methane oxidation coupled to sulfate respiration can be performed by a single microorganism, a member of the ancient kingdom of the Archaea, and does not need to be carried out in collaboration with a bacterium, as...

A team of scientists has documented for the first time that animals can and do consume Archaea — a type of single-celled microorganism thought to be among the most abundant life forms on Earth. Archaea that consume the greenhouse gas methane were in turn eaten by worms living at deep-sea cold seeps off Costa Rica and the West Coast of the United States. Archaea perform many key ecosystem services including being involved with nitrogen cycling, and they are known to be the main...

Study near Gulf of Mexico spill site finds surprisingly high methane uptake by microbes Microbes living at the bottom of the Gulf of Mexico may consume far more of the gaseous waste from the Deepwater Horizon oil spill than previously thought, according to research carried out within 100 miles of the spill site. A paper on that research, conducted before the Deepwater Horizon rig exploded six months ago today, will appear in a forthcoming issue of the journal Deep-Sea Research II. It...

The molecular secrets of a bacterium which produces its own oxygen to use the green house gas methane was unraveled A Dutch research team from the University of Nijmegen discovered bacteria that oxidize the methane without oxygen. Instead, these bacteria used nitrite, commonly available in freshwater sediments in agricultural areas. Methane is a very stable molecule and its degradation was generally believed to be impossible without oxygen (or sulfate). Now an international team from the The...

Scientists of the Helmholtz Centre for Environmental Research (UFZ) in Leipzig and the California Institute of Technology (Caltech) in Pasadena succeeded in capturing syntrophic (means "feeding together") microorganisms that are known to dramatically reduce the oceanic emission of methane into the atmosphere. These microorganisms that oxidize methane anaerobically are an important component of the global carbon cycle and a major sink for methane on Earth. Methane -- a more than 20 times...

Blacksburg, Va. -- Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth. The research appears in the Nov. 18, 2005 issue of the Journal of Biological Chemistry, in the article "A New Type of Sulfite Reductase, a Novel Coenzyme F420-dependent Enzyme, from the Methanoarchaeon Methanocaldococcus...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
