Uranium Removal with Protein Nanowires

Executive SummarySoil and groundwater contamination with uranium and radioactively contaminated waste pose serious environmental problems for human and animal consumption. Researchers at MSU have discovered that protein nanowire-expressing microorganisms are highly effective at precipitating and immobilizing heavy metal elements, including uranium,...

Microbial Rectifiers and Uses Thereof

IntroductionWhen grown in vitro under various conditions, Geobacteraceae bacteria produce conductive protein filaments known as microbial or pilus nanowires. These microbial nanowires show promise for applications in nanoelectronics and bio-electronics. Current methods for producing microbial nanowires are limited by an inability to produce microbial...

Microbial Fuel Cells for Efficient Bioenergy Conversion

IntroductionMicrobial fuel cells (MFC), or electrochemical or biological cells, are used to convert biomass material into liquid fuel and ultimately into electricity. They convert chemical energy into electrical energy through the catalytic reaction of micro-organisms. This process occurs in nature, and researchers have had difficulty effectively and...
