A Team of researchers in the Indian Institute of Technology, Kharagpur has claimed of making a significant breakthrough in isolating a hydrogen-producing bacterial strain that produces 40 per cent more hydrogen than other bacterial strains.
The development is considered to be significant in the production of hydrogen gas, an efficient and clean fuel.
According to Prof Debatrata Das, who is heading the research team, Enterobacter cloacae can produce about 3.85 moles of hydrogen from one mole of the substrate, which is very close to the theoretical limit of 4 moles of hydrogen during anaerobic fermentation.
The researchers have also used sewage as a substrate and have gotten similar results. This could be pretty important because it could mean the ability to produce fuel while at the same time disposing of a waste stream.
