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...

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...

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...

Bacteria that generate significant amounts of electricity could be used in microbial fuel cells to provide power in remote environments or to convert waste to electricity. Professor Derek Lovley from the University of Massachusetts, USA isolated bacteria with large numbers of tiny projections called pili which were more efficient at transferring electrons to generate power in fuel cells than bacteria with a smooth surface. The team's findings were reported at the Society for General...
