ANSWER: Hydrogen
Explanation:
Scientists have come up with reasonably priced, efficient biomaterial which catalyses the formation of hydrogen leading to eco-friendly ways to produce the biofuel. The biomaterial was produced by Indiana University Researchers which is 150 times more efficient than unaltered form of enzyme and attains strength from being protected with protein shell or capsid of bacterial virus. The genetic material used to create the enzyme, hydrogenase, is produced by two genes from the common bacteria Escherichia coli which is inserted inside the protective capsid. Resulting biomaterial is called P22-Hyd and is produced through a simple fermentation process at room temperature and it breaks the chemical bonds of water to create hydrogen and also works in reverse to recombine hydrogen and oxygen to generate power.
