“…Under aerobic conditions, this phenomenon is not manifested since molecular O 2 suppresses expression of the genes associated with H 2 metabolism, undermines the stability of the respective mRNAs, and inhibits the function of the related enzymes (Happe and Naber 1993;. Historically, this multi-point inhibition was alleviated upon a prior anaerobic incubation of the algae in the dark, often referred to as 'induction' (Kessler 1973;Lien and San Pietro 1981;Greenbaum 1982;Roessler and Lien 1984;Miyamoto et al 1990;Happe and Naber 1993;Schulz 1996). Under such anaerobic conditions, the positive suppression of gene expression by O 2 was lifted, and the unicellular green algae expressed the constituents of cellular H 2 metabolism.…”

This article summarizes knowledge on genes and their respective proteins in the field of green algal hydrogen research. Emphasis is placed on recently cloned genes from the unicellular green alga Chlamydomonas reinhardtii, including HydA1 and HydA2, which encode homologous [Fe]-hydrogenases, Tla1, which encodes a chlorophyll antenna size regulatory gene, SulP, which encodes a chloroplast sulfate permease, and Sta7, which encodes an isoamylase. Analysis of the structure and function of these genes and of their respective proteins in C. reinhardtii, and related unicellular green algae, is presented in light of the role they play in the hydrogen metabolism in these organisms. A discussion is offered as to the potential application of these genes in the field of hydrogen photoproduction.

The rapid development of clean fuels for the future is a critically important global challenge for two main reasons. First, new fuels are needed to supplement and ultimately replace depleting oil reserves. Second, fuels capable of zero CO2 emissions are needed to slow the impact of global warming. This review summarizes the development of solar powered bio-H2 production processes based on the conversion of photosynthetic products by fermentative bacteria, as well as using photoheterotrophic and photoautrophic organisms. The use of advanced bioreactor systems and their potential and limitations in terms of process design, efficiency, and cost are also briefly reviewed.
