Overview
Symbiotic bacteria undergo different metabolic processes to producing bio-hydrogen. Symbiotic bacteria that use metabolic processes to produce biohydrogen from food waste are usually anaerobic, which means they do not need oxygen. Photo and Dark fermentation are both anaerobic processes. Light energy then goes into the bacterial photosystem with biomass, this creates 2 electrons, which will produce H2. Direct and indirect both are aided by the photosystems that absorb water and light. Then electrons go into the enzyme hydrogenase that materializes H2.
Benefits:
Currently, research is being done on how food waste from humans and animals can be artificailly fermented by humans. If this works, this would be a good and efficient way to produce bio- hydrogen. Biohydrogen is the great fuel because it burns clean (does not affect any part of the environment). It is also a lot cheaper in the long term, and needs almost no energy. Biohydrogen can help save the earth, and cause positive benefits to overall society.
A chemical engineer works with bio-technology to design an efficient system for symbiotic bacteria to create bio hydrogen.
