Scientists uncover how cyanobacteria converts CO2 so efficiently

Scientists uncover how cyanobacteria converts CO2 so efficiently

February 9, 2020 |

In Germany, a research team from Ruhr-Universität Bochum revealed the secret of how cyanobacteria converts CO2 which makes it possible to use the information to improve the production of sustainable fuels for example. By analyzing the molecular structure of the complex using cryo-electron microscopy in combination with computer simulations and other biochemical experiments, the team […]

Simplified process developed to create synthetic adipates, saving energy and costs

Simplified process developed to create synthetic adipates, saving energy and costs

January 11, 2020 |

In Germany, researchers at the Ruhr-Universität Bochum found a way to develop simpler synthetic adipates which are required for the manufacturing of perfumes, lubricants and active pharmaceutical ingredients. So far, the reaction to produce adipates has only been possible using a complicated, multi-stage process. Now it only takes one step. Adipates are made from the […]

New findings can help protect hydrogen-producing enzymes from harmful oxygen

New findings can help protect hydrogen-producing enzymes from harmful oxygen

November 10, 2019 |

In Germany, researchers at the Ruhr-Universität Bochum found that certain enzymes, such as the hydrogen-producing hydrogenases, are unstable in the presence of oxygen and have clarified this at the atomic level. Using X-ray diffraction, they showed how certain iron atoms in the center of the enzyme change in the presence of oxygen, which gradually leads […]

Catalyst that lives forever? Researchers make efficient biocatalysts that last longer

Catalyst that lives forever? Researchers make efficient biocatalysts that last longer

November 3, 2019 |

In Germany, researchers at the Ruhr-Universität Bochum have succeeded in equipping a catalyst with an extremely thin protective film of molecular building blocks, which shields it from oxygen and thus makes its life practically infinite. The catalyst still works efficiently. Oxygen threatens sustainable catalysts that convert hydrogen into fuel cells but researchers have developed a […]

Converting CO 2 into raw materials using nanoparticles

Converting CO 2 into raw materials using nanoparticles

September 28, 2019 |

In Germany, scientists at the Ruhr University Bochum and the University of New South Wales in Australia converted carbon dioxide into raw materials using nanoparticles. They looked at the principle for this from enzymes that produce complex molecules in many-step reactions. The team transferred this mechanism to metallic nanoparticles, also called nanozymes. For example, chemists […]

Oil-accumulating fungi research could help biofuels production

Oil-accumulating fungi research could help biofuels production

September 15, 2019 |

In Germany, mushroom genetics research, conducted by Ruhr-Universität Bochum researchers and others, could help biofuel production. Some species of trichosporonales fungi can store large amounts of lipids in their cells, and are so-called oil-accumulating fungi, which have therefore been increasingly analyzed in recent years as potential producers of biofuels. Trichosporonales fungi are widespread in the […]

Researchers develop targeting of light-activated proteins

Researchers develop targeting of light-activated proteins

August 18, 2019 |

In Germany, researchers at the Ruhr-Universität Bochum (RUB) have developed a new strategy for the design of light-sensitive proteins. Such proteins, also called optogenetic tools, can be switched on and off by light pulses, thereby triggering targeted cellular processes. With their help, it is possible, for example, to study in living organisms and to control […]

Longer life for bioelectrodes with oxygen-free environment

Longer life for bioelectrodes with oxygen-free environment

April 28, 2019 |

In Germany, a research team from Ruhr-Universität Bochum has shown that operation in an oxygen-free environment significantly prolongs the life of the bioelectrode. “In order to generate energy sustainably and efficiently, we must not only understand but also overcome the processes that limit the lifetime of renewable energy conversion technologies,” says Wolfgang Schuhmann. The use […]

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 […]
