Özet

Microalgae have been drawn great attention due to their biohydrogen production potentials. In this study, we investigated biohydrogen production potentials of Chlamydomonas reinhardtii strains as D1 protein mutant strain D240-41, PGRL1 single mutant PGRL1 mt (+), PGRL1 double mutant PGRL1x∆nd4 Véro. Biohydrogen productions were carried out according to HS-HS strategy. This new strategy is based on performing hydrogen production by completing two successive phases, aerobic and anaerobic. In the first phase, the cultures were cultivated in HS medium under aerobic condition, then in the second phase they were transferred to anaerobic photobioreactors containing fresh HS medium. As result, we observed that all strains were able to produce hydrogen during this new HS-HS strategy.
