The University of the West of the England (UWE Bristol) researchers (Ieropoulos & Greenman) have revealed that technology they have developed which has already been proven to produce electricity through the process of organic waste, such as urine, also destroys the bacteria which is harmful to the human health. This is the scientific innovation which taken evolving biotechnology a step closer to being used to treat wastewater in the Developing World.

The experts of this research show that they have developed a special process in which the waste water drifts through a chain of cells filled with electroactive microbes. And these microbes can be used to attack and kill a pathogen the potentially deadly Salmonella.

The leader of this research professor Ioannis Ieropoulos said that it was important to launch the technology could tackle pathogens in order for it to be considered for use in the Developing World.

These finding of this research have been published in leading scientific journal “PLOS ONE”. The leader of the research Professor Ioannis Ieropoulos who is also the Director of the Bristol BioEnergy Centre, which is based at the Bristol Robotics Laboratory at UWE Bristol, said it was globally the very first time that it had been described that pathogens could be ruined using this method.

“We were really excited with the results it shows we have a stable biological system in which we can treat waste, generate electricity and stop harmful organisms making it through to the sewerage network.”

Dr. Ieropoulos created MFC technology could clean organic waste, including urine to that level that it could be safely released into the environment. The electricity which is created through this process is enough to charge the cell phone or power lighting in earlier trials.

The unique system being developed with the help of the funding from the Bill &Melinda Gates Foundation. The microbes inside the fuel cells are consumed by the organic content of urine, breaking it down and creating energy.

Emeritus Professor of Microbiology, John Greenman said: “The wonderful outcome in this study was that tests showed a reduction in the number of pathogens beyond the minimum expectations in the sanitation world. We have reduced the number of pathogenic organisms significantly but we haven’t shown we can bring them down to zero we will continue to work to test if we can completely eliminate them.”
