Last year, Cambridge University researchers used a mix of biological and technological components to achieve unassisted solar-driven water-splitting, using natural sunlight to convert water into hydrogen and oxygen using hydrogenase, a long-dormant enzyme in algae.
In 2000, Melis and his co-worker created the S-deprivation inducing [H.sub.2] photoproduction model because S-deficiency damaged photosynthetic oxygen complex, so the oxygen released by photosynthesis cannot compensate the respiratory oxygen consumption, and gradually anaerobic status was achieved and hydrogenase activity was induced, which dramatically improved photosynthetic [H.sub.2] photoproduction efficiency and prolong the hydrogen producing period to hundred of hours (3).
This is first of its kind model to use hydrogenase and photosystem II for creating semi-artificial photosynthesis supported entirely by solar power.
She explained: "Hydrogenase is an enzyme present in algae that is capable of reducing protons into hydrogen.

In particular, the coupling between semiconductors and biomimetic complexes (i.e., hydrogenase, formate dehydrogenases, and carbon monoxide dehydrogenases mimics) may reveal to be an efficient strategy for aiding the C[O.sub.2] reduction, improving the current solar fuel technologies and stimulating the applications of these devices.

High Bcl-XL levels and low numbers of apoptotic lymphoma cells were reported to be significantly associated with multiple sites of extranodal involvement, elevated lactated hydrogenase level, and short overall survival time [36].
Gallinarum has lost several metabolic pathways including the inability to use long chain maltodextrins, D-glucarate and hydrogenase 1.
