概要 The effects of increasing the heterocyst-to-vegetative cell ratio on the nitrogenase-based photobiological hydrogen production by the filamentous heterocyst-forming cyanobacterium Anabaena sp. PCC 7120 were studied. In a PatN mutant (PN22), the percentage of heterocysts to total cells in filaments was 13-15 and 16-18% under air and 1% CO2-enriched air, respectively, in contrast to the parent ΔHup which formed 6.5-11 and 9.7-13% . The PN22 strain exhibited higher H2 productivity at high cell concentrations, and was less susceptible to photoinhibition by strong light than the parent ΔHup strain, resulting in greater light energy utilization efficiency in H2 production on a per unit area basis under high light conditions.
