Hydrogen-producing enzymes from green algae looked at for biotech potential

Hydrogen-producing enzymes from green algae looked at for biotech potential

January 10, 2021 |

In Germany, Ruhr-Universität Bochum researchers are looking at how hydrogen-producing enzymes, or hydrogenases, could be a source of regenerative energy. A hydrogenase from the green alga Chlamydomonas reinhardtii , which has so far hardly been researched, has now been characterized more precisely by the RUB photobiotechnology working group. Enzyme twin with biotechnological potential Green algae […]

Arzeda and Amyris enter into joint development agreement for novel enzymes

October 25, 2020 |

In Washington, Arzeda, the Protein Design Company, entered into a joint development agreement with Amyris to design and develop novel enzymes for Amyris with unique functionalities, which Amyris will incorporate into their fermentation process to facilitate production of the target high value ingredients. This marks the second joint project between the parties. Amyris and Arzeda […]

Cyanobacteria as green catalysts in biotech, researchers turn off unnecessary energy consumer

Cyanobacteria as green catalysts in biotech, researchers turn off unnecessary energy consumer

October 11, 2020 |

In Germany, researchers from the Technical University Graz and the RUB were able to increase the catalytic activity of cyanobacteria and makes them more attractive for biotechnological use, where they could be used with targeted enzymes as eco-friendly and readily available biocatalysts for the production of new chemicals. Cyanobacteria, which – although they color water […]

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. […]

NREL achieves sugar yields greater than 90% with low enzyme loadings on biomass

NREL achieves sugar yields greater than 90% with low enzyme loadings on biomass

May 31, 2020 |

In Colorado, National Renewable Energy Laboratory researchers experimented with a common method in the pulp and paper industry used for bleaching to see how well this method could deconstruct biomass. The method known as “ozonolysis” was applied to corn stover in the lab. Results showed that using ozonolysis helped to breakdown the biomass with a […]

Carbios Clearing the Bottleneck – Enzymatic recycling tech hits 90% depolymerization in 10 hours

April 12, 2020 |

As many stay home doing their part to flatten the curve, people will be singing the annoyingly popular “99 bottles” song but with a new twist: “99 bottles of pop on the wall, 99 bottles of pop…you take one down, you run it through Carbios’s tech, still 99 bottles of pop on the wall.” News […]

Researchers find new way to drive biocatalysis with plasmas

Researchers find new way to drive biocatalysis with plasmas

March 15, 2020 |

In Germany, a research team from Ruhr-Universität Bochum developed a new method to drive catalytically active enzymes, using a process in which the starting material hydrogen peroxide is supplied to the biocatalysts in a controlled manner using plasma. A buffer layer protects the enzymes themselves from harmful components of the plasma. Using two model enzymes, […]

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 […]

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 […]

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. […]
