Generating current from waste || GREEN FUEL

A purple bacteria which store energy from light can help harvest hydrogen fuel 

From sewage and recover carbon from any type of organic waste scientists have found.

Organic compounds in household sewage and industrial wastewater are a rich potential source of energy. Bio-plastics and even proteins for animal feed but with no efficient extraction method treatment plants discard them as Contaminants.

A study published in the journal Frontiers in Energy Research in The first to show that supplying electric current to purple 

"Phototrophic bacteria can recover nearly 100 per cent of carbon from any type of organic waste" 

while generating hydrogen gas for electricity production.

"One of the most important problems of current wastewater treatment plants is high carbon emissions" said Daniel Puyol of King Juan Carlos University in Spain.

They also tested the effect of a negative current that is electrons supplied by metal electrodes. 

In the growth medium on the metabolic Behaviour of the bacteria.

The first key finding was that the nutrient blend that fed the highest rate of Hydrogen production also minimised the CO2.

"This demonstrates that purple bacteria can be used to recover valuable bio fuel from organics typically found in wastewater "
