Hydrogen Energy and Biotechnology

Abstract

Biological hydrogen production has been carried out to develop a renewable and environmentally acceptable energy source. Hydrogen production by photosynthetic bacteria and cyanobacteria is one approach that has been investigated extensively. Double phase photobioreactor was used to increase hydrogen production from marine photosynthetic bacteria. The hydrogen production was enhanced 5 times higher than the conventional reactors. Marine cyanobacteral strains in the genus Cyanothece at ourculture collection were dividedinto two groups by resulting from hydrogen production rates and phylogenetic analysis using 16S rDNA. Floating culture using floating materials (coal fly ash block: CFAB) and adhesive marine cyanobacterial of Synechococcus sp. was successfully performed in an artificial medium. Cell growth on surface of CFAB was enhanced in the seawater as compared with the artificial medium.
