Biodiesel Made Sustainable With New, Fossil-fuel-free Process
2014-05-23 03:07:28

Michigan State University A new fuel-cell concept, developed by an Michigan State University researcher, will allow biodiesel plants to eliminate the creation of hazardous wastes while removing their dependence on fossil fuel from their production process. The platform, which uses microbes to glean ethanol from glycerol and has the added benefit of cleaning up the wastewater, will allow producers to reincorporate the ethanol and the water into the fuel-making process, said Gemma...

Unexpected Properties Of Methane-producing Microbe Revealed
2013-11-19 08:31:36

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...

Electrically Conducting Bacteria Important For Energy, Environment And Technology
2013-11-13 10:52:15

Pacific Northwest National Laboratory Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and miniaturizing computers. "This is the first atomic resolution structure of this protein from an electrically conductive bacterial species, and it sets the...

Most of us wouldn't consider bacteria a promising energy source of the future. That would be shortsighted, says Leonard Tender, a microbial-electrochemist at the Naval Research Laboratory in Washington, D.C., who believes that the focus of his research – electrode reactions catalyzed by microorganisms – may one day provide cheap, clean and abundant energy by converting the carbon dioxide in seawater to fuel and the organic matter in wastewater into electrical power. Tender will discuss...

Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, Amherst report their findings at the 113th General Meeting of the American Society for Microbiology. "This represents the first result of current production solely on hydrogen," says Amit Kumar, a researcher on the study who, along with his co-authors are part of...

Slender bacterial nanowires require certain key amino acids in order to conduct electricity, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology, on Tuesday, March 12. In nature, the bacterium Geobacter sulfurreducens uses these nanowires, called pili, to transport electrons to remote iron particles or other microbes, but the benefits of these wires can also be harnessed by humans for use in fuel cells or...

Using Microbes To Convert Heavy Metals
2012-09-30 07:22:29

Brett Smith for redOrbit.com - Your Universe Online New research from University of California at Berkeley scientists could have a big impact on toxic metal clean-up at hundreds of sites around the United States and the world. Using a groundbreaking metagenomic sequencing analysis on underground microbes at a contaminated uranium mill in Colorado, the UC Berkeley research team identified 150,000 genes that were assigned to 80 different microbes that live in the soil, according to their...

The discovery of a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances could revolutionize nanotechnology and bioelectronics, says a team of physicists and microbiologists at the University of Massachusetts Amherst. Their findings reported in the Aug. 7 advance online issue of Nature Nanotechnology may one day lead to cheaper, nontoxic nanomaterials for biosensors and solid state...

New cooperative behavior, interspecies electron transfer; identified in anaerobic bacteria University of Massachusetts Amherst microbiologists Derek Lovley, Zarath Summers and colleagues report in the Dec. 2 issue of Science that they have discovered a new cooperative behavior in anaerobic bacteria, known as interspecies electron transfer, that could have important implications for the global carbon cycle and bioenergy. The scientists found that microorganisms of different species, in this...

Showcasing its energy research initiatives for an Earth Day event on April 22 at the Pentagon, the Office of Naval Research (ONR) will highlight the microbial fuel cell, a device with the potential to revolutionize naval energy use by converting decomposed marine organisms into electricity. These fuel cells convert naturally occurring fuels and oxidants in the marine environment into electricity, offering a clean, efficient and reliable alternative to batteries and other environmentally...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
