Bacteria normally found 30km above the earth have been identified as generators of electricity.
Bacillus stratosphericus – a microbe commonly found in high concentrations in the stratosphere orbiting the earth with the satellites – is a key component of a new 'super' biofilm that has been engineered by a team of scientists from Newcastle University.
MFC which work in a similar way to a battery, use bacteria to convert organic compounds directly into electricity by a process known as bio-catalytic oxidation. A biofilm – or 'slime' – coats the carbon electrodes of the MFC and as the bacteria feed, they produce electrons which pass into the electrodes and generate electricity.
