Abstract

Abstract: Under certain conditions, cyanobacteria can switch from photosynthesis to hydrogen production, which is a good energy carrier. However, the biological diversity of hydrogen-releasing cyanobacteria has a great unexplored potential. This study is aimed to investigate the ability of new strains of cyanobacteria Cyanobacterium sp. IPPAS B-1200, Dolichospermum sp. IPPAS B-1213, and Sodalinema gerasimenkoae IPPAS B-353 to release H2 and to evaluate the effects of photosystem II inhibitor 3-(3, 4-dichlorphenyl)-1, 1-dimethylurea (DCMU) on H2 production under light and dark conditions. The results showed that cultures treated with DCMU produced several times more H2 than untreated cells. The highest rate of H2 photoproduction of 4.24 μmol H2 (mg Chl a h) −1 was found in a Dolichospermum sp. IPPAS B-1213 culture treated with 20 μM DCMU. Graphical abstract: Image 1 Highlights: The ability of three new cyanobacterial strains to release hydrogen was studied. The highest H2 yield was in the Dolichospermum sp. IPPAS B-1213 strain under light anaerobic conditions. Sodalinema gerasimenkoae IPPAS B-353 released hydrogen only in the dark. H2 production rate increased in presence of photosynthesis inhibitor.
