University of Massachusetts at Amherst Derek Lovley's lab at UMass Amherst show for the first time that one of the most abundant methane-producing microorganisms on Earth makes direct electrical connections with another species to produce the gas in a completely unexpected way For 40 years, scientists thought they understood how certain bacteria work together to anaerobically digest biomass to produce methane gas, important in bioenergy and the major source of greenhouse gas. But now...

DNA Of Ancient Microorganisms Provide Clues On Origins Of Life
2013-03-08 11:41:26

April Flowers for redOrbit.com - Your Universe Online Important genetic clues about the history of a group of ancient microorganisms called archaea and the origins of life itself have been discovered by a team of researchers. Results of this first-of-its-kind study shed light on one of Earth's oldest life forms. "Archaea are an ancient form of microorganisms, so everything we can learn about them could help us to answer questions about the origin of life," explained William Whitman,...

Matt Shipman, North Carolina State University Researchers have long known that landfills produce methane, but had a hard time figuring out why "“ since landfills do not start out as a friendly environment for the organisms that produce methane. New research from North Carolina State University shows that one species of microbe is paving the way for other methane producers. Specifically, the researchers found that an anaerobic bacterium called Methanosarcina barkeri appears to be the key...

U.S. scientists say they have discovered marine microorganisms use manganese and iron to convert methane into carbon dioxide. The Pennsylvania State University researchers said their finding is important because carbon dioxide can produce compounds that sequester carbon in the ocean, reducing the amount of CO2 in the Earth's atmosphere. That process had previously been thought to be dependent on compounds containing sulfur. Graduate student Emily Beal, principal author of the study, said the...

U.S. and British scientists have determined nickel might be a useful isotopic marker to trace the origins of single cell organisms that produce methane. Our data suggest significant potential in nickel stable isotopes for identifying and quantifying methanogenesis on the early Earth, said Vyllinniskii Cameron, a recent Penn State graduate and now a post-doctoral fellow at the University of Bristol. Little is known about the actual timing of the evolution of methane producing organisms or...

Nickel, an important trace nutrient for the single cell organisms that produce methane, may be a useful isotopic marker to pinpoint the past origins of these methanogenic microbes, according to Penn State and University of Bristol, UK, researchers."Our data suggest significant potential in nickel stable isotopes for identifying and quantifying methanogenesis on the early Earth," said Vyllinniskii Cameron, recent Penn State Ph.D. recipient in geosciences and astrobiology and currently a...

U.S. scientists say they've discovered microbes can directly convert carbon dioxide and water to methane without generating hydrogen. Pennsylvania State University Professor Bruce Logan said his team made the discovery while studying making hydrogen in microbial electrolysis cells. We kept getting all this methane, he said. We may now understand why. Methanogenic microorganisms produce methane in marshes and dumps but scientists thought the organisms turned hydrogen or organic materials, such...

A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. "We were studying making hydrogen in microbial electrolysis cells and we kept getting all this methane," said Bruce E. Logan, Kappe Professor of Environmental Engineering, Penn State. "We may now understand why." Methanogenic microorganisms do produce methane in marshes and...

WASHINGTON, Jan. 15 /PRNewswire-USNewswire/ -- A team of NASA and university scientists has achieved the first definitive detection of methane in the atmosphere of Mars. This discovery indicates the planet is either biologically or geologically active. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The team found methane in the Martian atmosphere by carefully observing the planet throughout several Mars years with NASA's Infrared Telescope Facility and the W.M. Keck...

NASA TV's broadcast on Thursday confirmed that Mars is, indeed, an active planet in our solar system, as the first definitive detection of methane gas has been released into the red planet's atmosphere. Michael Meyer, the lead scientists of the Mars program at NASA, headed a broadcast panel of NASA and University scientists who stated that it is not yet known whether the methane sources were produced geologically or biologically"”suggesting microbial activity of an alien nature. Michael...
