Scientists have been hard at work harnessing the power of microbes as an attractive source of clean energy. Now, Biodesign Institute at Arizona State University researcher Dr. Prathap Parameswaran and his colleagues have investigated a means for enhancing the efficiency of clean energy production by using specialized bacteria. Microbial electrochemical cells or MXCs are able to use bacterial respiration as a means of  liberating electrons, which can be used to generate current and make...

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...

PNAS study documents puzzling movement of electricity-producing bacteria near energy sources. Bacteria dance the electric slide, officially named electrokinesis by the USC geobiologists who discovered the phenomenon. Their study, published online Dec. 15 in PNAS Early Edition, describes what appears to be an entirely new bacterial behavior. The metal-metabolizing Shewanella oneidensis microbe does not just cling to metal in its environment, as previously thought. Instead, it harvests...

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...

A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S.Clean water for drinking, washing and industrial uses is a scarce resource in some parts of the world. Its availability in the future will be even more problematic. Many locations already desalinate water using either a reverse osmosis process -- one that pushes water under high pressure through...

Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms.The bacteria, Shewanella, are commonly found in water and soil and are of interest because they can convert simple organic compounds (such as lactic acid) into electricity, according to Daniel Bond and Jeffrey Gralnick, of the University of Minnesota's BioTechnology...

CANBERRA, Australia -- Scientists and Australian beer maker Foster's are teaming up to generate clean energy from brewery waste water - by using sugar-consuming bacteria. The experimental technology was unveiled Wednesday by scientists at Australia's University of Queensland, which was given a $115,000 state government grant to install a microbial fuel cell at a Foster's Group brewery near Brisbane, the capital of Queensland state. The fuel cell is essentially a battery in which bacteria...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
