Molecular hydrogen is one of the potential energy sources that could be an alternative to fossil fuel resources. Cyanobacteria are microorganisms with the potential to produce hydrogen. Compared to traditional methods of obtaining hydrogen (chemical, photoelectric), hydrogen production by cyanobacteria is a commercially viable process. This project proposal focuses on the identification of new cyanobacterial strains capable of expressing hydrogenases with high efficiency to produce increased amounts of hydrogen. Various molecular biology techniques, including cyanobacterial transformation and gene knockout, will be employed, which will be assimilated by the project manager following a training period in an experienced laboratory.
