Photoautotrophic and sustained H2 production by the pgr5 mutant of Chlamydomonas reinhardtii in simulated daily light conditions
Valéria Nagy, Zsombor Dabosi, Soujanya Kuntam, Krisztián Csankó, László Kovács, Szilvia Zita Tóth
International Journal of Hydrogen Energy (2024)
Impact Summary
This study evaluates the remarkable potential of the pgr5 mutant of Chlamydomonas reinhardtii for continuous bio-hydrogen generation under realistic, fluctuating lighting. By testing the strain in automated thin cell layer photobioreactors under simulated daily conditions, the research demonstrates its capacity for sustained photoautotrophic H2 production. This marks a critical milestone in identifying robust microalgae strains capable of withstanding the dynamic outdoor environments required for large-scale, commercial bio-hydrogen facilities.
