Electricity To Be Generated From Bacteria!

Shewanella_oneidensisA recent study conducted by a team of researchers at the University of East Anglia has demonstrated for the very first time the protein molecular structure of the bacteria that helps in transferring electric charge.

The study was led by Dr Tom Clarke, Professor Julea Butt and Professor David Richardson.

This promising discovery means that the bacteria can now be bound to the electrodes directly to create bio-batteries or microbial fuel cells.

According to Dr Clarke, the identification of the molecular structure of the primary proteins involved in the process of electron movement form the inside to the outside of the cell is a significant step in considering microbes as the future viable sources of electricity.

The study involved the usage of a technique known as X-ray crystallography, which unfolded the molecular structures of the proteins that were adhering to the cell surface of Shewanella oneidensis (a bacterium that has the ability to clean up heavy metal wastes in the environment) through which electron tranfer occurs.
