We showed that H 2 production was enhanced by the co-expression of proteorhodopsin and [NiFe]-hydrogenase in recombinant E. coli BL21(DE3) in a light intensity-dependent manner. Biological methods have been studied to ensure the hydrogen production is safer and more economical than thermochemical methods. One potential alternative is biohydrogen (H2), a clean energy carrier with high-energy yields; upon the combustion of H2, H2O is the only major by-product. It was found that nitrogen source content (0–4 g/L) could promote biohydrogen production and cell growth. The hydrogen yields for cobalt, nickel and mixture of Co–Ni salts supplemented system were 0.15, 0.28 and 0.3 mol H 2 /mol glucose, respectively. In addition, the book discusses mathematical modeling of the various … This method doesn’t require light energy. It is highly combustible and can be used as a fuel or for the production of electricity. It also gives insight into scale-up problems and limitations. In recent decades, the attractive and renewable characteristics of H2 led us to develop a variety of biological routes for the production of H2. ... . Require wet carbohydrate rich biomass as a substrate. The state-of-the-art for four different biohydrogen production mechanisms is reviewed, including biophotolysis, indirect biophotolysis, photofermentation, and dark fermentation. The process is feasible from practical point of view and can be operated under ambient conditions. Hydrogen Production Processes; Hydrogen can be produced using a number of different processes. Generation of H 2 gas either by biological machinery or through thermochemical treatment of biomass can be defined as “biohydrogen” ().Incidentally, thermochemically produced H 2 is also being termed as biohydrogen due to the usage of biomass as a substrate/feedstock.
