Lowering carbon emissions so as to stop climate change needs designing new techs for renewable and sustainable production of biofuel. Molecular hydrogen is considered as one of the most capable carriers of energy owing to its carbon-free, clean use, and high energy density. A research team from Finland at the University of Turku has found a competent approach for creating biohydrogen’s chemical energy from solar energy via green algae’s photosynthesis that works as cell factories.
At the time of photosynthesis, green algae use harvested solar power to split molecules of water, emit oxygen into the air, and generate biomass that works as an outstanding feed-stock.
Green algae are also well-organized biocatalysts and can convert carbon dioxide and solar energy directly into various valuable compounds, such as antioxidants, vitamins, carbohydrates, and polymers.
“When algal cells are initially incubated under anaerobic circumstances in the dark and then uncovered in light, they begin creating hydrogen competently, but regrettably only for a couple of seconds,” claims Yagut Allahverdiyeva-Rinne, the head of the research team and Associate Professor at the University of Turku for Molecular Plant Biology.
Scientists for decades have already believed that the main challenge to the ever-lasting production of hydrogen in light in algae is the annihilation of the hydrogenase enzyme. It is an important component in this procedure.
“Since algae continuously emit oxygen at the time of their photosynthesis that takes place simultaneously with the making of hydrogen, maintenance of anaerobic circumstances in illuminated cultures has been predominantly bothersome,” claims Sergey Kosourov, the senior researcher and a member of the research team, to the media in an interview.
On a similar note, a team of researchers from the University of Turku is researching on what the community of University of Texas thinks about campus carry, which drew worldwide attention when in 2016 it turned out to be a state law.
