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. […]

CARBIOS and CARBIOLICE sign agreement with Novozymes for enzymes

February 17, 2019 |

In France, bioplastics company CARBIOS and its subsidiary CARBIOLICE, signed a co-development agreement with enzyme production leader Novozymes. Under the terms of this global and multi-year agreement, Novozymes will produce on an industrial scale the proprietary enzyme developed by CARBIOS and is committed to becoming, in the long term, exclusive supplier of CARBIOLICE. “This unprecedented […]

Russian scientists develop method to enhance enzymes using radio frequency radiation

Russian scientists develop method to enhance enzymes using radio frequency radiation

January 1, 2019 |

In Russia, scientists at ITMO University developed a method to enhance the activity of enzymes by using radio frequency radiation. The method requires making a special complex consisting of enzymes and magnetic nanoparticles. The particles can adsorb radio emission and convert it to heat, resulting in enzymatic processes acceleration by more than four times. Such […]

In Australia, University of Queensland researchers have stabilized biocatalyst enzymes that used to fall apart outside the body and at high temperatures so that they don’t do that anymore, which can be useful for carrying out chemical transformations under industrial conditions, such as producing biofuels. They made more heat tolerant and stronger versions of two […]

Researchers develop mechanism to protect enzymes from oxygen

Researchers develop mechanism to protect enzymes from oxygen

September 17, 2018 |

In Germany, an international team of researchers has developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new […]

Biologist gets $800K grant to improve biofuel production

Biologist gets $800K grant to improve biofuel production

September 2, 2018 |

In Arkansas, University of Arkansas biologist Ruben Michael Ceballos is developing methods that could make the production of biofuel more efficient and environmentally sound using a protein derived from microorganisms that live in acidic geothermal pools and springs to enhance the process of turning organic material into fuel. Ceballos, an assistant professor in the Department […]

UK and US researchers discover family of enzymes converting biomass into high value bioproducts

UK and US researchers discover family of enzymes converting biomass into high value bioproducts

August 7, 2018 |

In the UK, new family of enzymes has been discovered which paves the way to convert plant waste into sustainable and high-value products such as nylon, plastics, chemicals, and fuels. The discovery was led by members of the same UK-US enzyme engineering team which, in April, improved a plastic-digesting enzyme, a potential breakthrough for the […]

ORNL researchers find additional biofuel and bioproduct uses for enzymes

June 18, 2018 |

In Tennessee, for decades, biologists have believed a key enzyme in plants had one function—produce amino acids, which are vital to plant survival and also essential to human diets. But for Oak Ridge National Lab researchers, this enzyme does more than advertised. They had run a series of experiments on poplar plants that consistently revealed […]
