Everything from diesel to ethanol helps us to continue taking advantage of the benefits of modern infrastructure while reducing the impact those activities have on the environment. Researchers at two east china universities have found a way to use green algae to continuously generate hydrogen in natural environments for up. Chlamydomonas reinhardtii has the ability to produce hydrogen and this is dependent on the expression of hydrogenase enzyme. Production of hydrogen from microalgae has been gathering much contemplation right away.

Hydrogen production from algae the science show abc. Increasing efficiency of hydrogen production from green algae. Microalgae perform direct photolysis through photosynthesis. Historically, hans gaffron made the first observation of hydrogen metabolism in green algae gaffron, 1939, 1944. Traditionally the process has to be stopped periodically to remove dead algae and feed in new algae.
But, mercantile production of microalgae biofuels considering bio hydrogen is still not practicable because of low biomass concentration and costly down streaming processes. Melis estimates that, if the entire capacity of the photosynthesis of the algae could be directed toward hydrogen production, 80 kilograms of hydrogen. Biophotolysis is carried out by bluegreen algae that split water for biohydrogen production, is a planttype photosynthesis process that occurs in an anaerobic environment.
