Figure 1: Hydrogen production by enzymes of the ... from the oxidative pentose cycle means that the reaction is proceeding almost to completion as a result of the hydrogenase oxidizing NADPH ...

Special enzymes ... hydrogenase enzymes, advanced infrared spectroscopy, and electrochemical methods, the researchers investigated how this is possible. They demonstrated that the uptake of an ...

An ancient biological enzyme known as nickel-iron hydrogenase may play a key role ... meaning that the intermediates have an unpaired electron – which makes them extremely short-lived.” ...

The enzyme, extracted from a bacterium by researchers at Monash University in Australia, is also insensitive to oxygen, unlike all other hydrogen-oxidizing catalysts, including platinum. “The ...

In this context molecular hydrogen (H 2) is regarded an important energy carrier for future applications. Nature uses hydrogenase enzymes to mediate production and consumption of H 2. Presumably ...

They also designed a hydrogen/oxygen biofuel cell based on a hydrogenase enzyme together with a team from the Max Planck Institute for Chemical Energy Conversion. Both papers have been published ...

A team of chemists at the University of Illinois Urbana-Champaign have been investigating an ancient biological enzyme known as nickel-iron hydrogenase ... have an unpaired electron – which ...

In the absence of air, microorganisms produce hydrogen using an enzyme called [FeFe]-hydrogenase, one of the most efficient hydrogen-producing biocatalysts known and a promising tool for green ...

Since earth`s ancient times, microorganisms use enzymes, so-called hydrogenases. Enzymatic conversion of hydrogen is efficient, almost without energy loss, and, most importantly, without greenhouse ...
