Process To Convert Sugar Directly To Diesel Resurrected
2012-11-07 13:38:34

University of California - Berkeley Long-abandoned bacterial fermentation process resurrected to feed catalysis into fuel mixture A long-abandoned fermentation process once used to turn starch into explosives can be used to produce renewable diesel fuel to replace the fossil fuels now used in transportation, University of California, Berkeley, scientists have discovered. Campus chemists and chemical engineers teamed up to produce diesel fuel from the products of a bacterial...

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...

Biofuel Cooked From Algae
2012-11-01 05:47:29

Lee Rannals for redOrbit.com - Your Universe Online Engineers from the University of Michigan have pulled off a feat in a matter of minutes that takes Mother Nature millions of years. The researchers "pressure cooked" algae for as little as a minute and transformed 65 percent of the green slime into biocrude. "We're trying to mimic the process in nature that forms crude oil with marine organisms," said Phil Savage, an Arthur F. Thurnau professor and a professor of chemical...

In the past few years, high Btu landfill gas (LFG) recovery and treatment has received renewed attention because the process converts large amounts of methane from waste into a viable, renewable fuel. While this process upgrades landfill gas to specifications for natural gas pipeline transport, it also significantly reduces the environmental impact from the largest source of man-made greenhouse gas pollution. In partnership with IESI, a subsidiary of Progressive Waste Solutions, and the US...

Global Warming And Rice Production
2012-10-23 06:34:24

April Flowers for redOrbit.com - Your Universe Online A new study led by the University of California, Davis finds that more carbon dioxide in the atmosphere, coupled with rising temperatures, is making rice agriculture a larger source of the potent greenhouse gas methane. Relatively simple changes in rice cultivation, according to the study, could help reduce methane emissions. "Together, higher carbon dioxide concentrations and warmer temperatures predicted for the end of this...

Mars Methane Could Hint At Signs Of Life
2012-10-17 05:05:33

Lee Rannals for redOrbit.com - Your Universe Online An astronomy graduate student from New Mexico State University is looking into the possibility of finding life on Mars through detecting traces of methane gas. Malynda Chizek made a presentation during the American Astronomical Society's Division for Planetary Sciences meeting about her research studying the possible detection of methane gas on Mars. "There is an instrument onboard the Curiosity Rover -- which landed on Mars in...
