Researchers design hydrogen-oxygen biofuel cell based on hydrogenase enzyme

August 30, 2020 |

In Germany, researchers at Ruhr-University Bochum, University of Utah and the Max Planck Institute for Chemical Energy Conversion developed new techniques with which bacterial enzymes can be efficiently coupled to electrodes and designed a hydrogen-oxygen biofuel cell based on a hydrogenase enzyme. They also implemented a system for ammonia synthesis based on a nitrogenase enzyme. […]

Scientists look at how nature builds hydrogen-producing enzymes

Scientists look at how nature builds hydrogen-producing enzymes

July 28, 2019 |

In Germany, a team from the Ruhr-Universität Bochum and the University of Oxford has found out how hydrogen-producing enzymes, or so-called hydrogenases, are activated during their biosynthesis. They showed how the cofactor – a part of the active center and at the same time the heart of the enzyme – is introduced into the interior. […]

Proton pathway reproduced to understand how algae enzymes produce hydrogen

Proton pathway reproduced to understand how algae enzymes produce hydrogen

November 25, 2018 |

In Germany, scientists from Ruhr-Universität Bochum succeeded for the first time in understanding how certain algae enzymes produce hydrogen by reproducing the pathway of the protons to the active center of these [FeFe] hydrogenases. This could allow such efficient but vulnerable biocatalysts to be chemically more stable. The hydrogenases produce two protons and two electrons […]
