Scientists have developed a way to grow iron-oxidizing bacteria using electricity instead of iron, an advance that will allow them to better study the organisms and could one day be used to turn electricity into fuel. The study will be published on January 29 in mBio®, the online open-access journal of the American Society for Microbiology. The method, called electrochemical cultivation, supplies these bacteria with a steady supply of electrons that the bacteria use to respire, or...

Methane Consuming Microorganisms Have Strange Diet
2012-11-06 13:06:13

Max-Planck-Gesellschaft Methane supplies the energy for cell metabolism, but is not the carbon source Methane is formed under the absence of oxygen by natural biological and physical processes, e.g. in the sea floor. It is a much more powerful greenhouse gas than carbon dioxide. Thanks to the activity of microorganisms this gas is inactivated before it reaches the atmosphere and unfolds its harmful effects on Earth's climate. Researchers from Bremen have now proven that these...

Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter in deep ocean water, a finding that could dramatically change ideas about the ocean carbon cycle. Matthew McCarthy, associate professor of ocean sciences at the University of California, Santa Cruz, led a team of researchers from several institutions who analyzed the...

Researchers have discovered an isolated, self-sustaining, bacterial community living under extreme conditions almost two miles deep beneath the surface in a South African gold mine. It is the first microbial community demonstrated to be exclusively dependent on geologically produced sulfur and hydrogen and one of the few ecosystems found on Earth that does not depend on energy from the Sun in any way. The discovery, which appeared in the October 20 issue of Science, raises the possibility...


Word of the Day
