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

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 […]

Brazilian researchers isolate enzyme for bagasse saccharification in the Amazon

Brazilian researchers isolate enzyme for bagasse saccharification in the Amazon

May 15, 2018 |

In Brazil, missing piece of the puzzle to achieving second-generation ethanol from sugarcane bagasse is saccharification – saccharification meaning the process by which complex sugars called polysaccharides are depolymerized and broken down into simple soluble sugars. This would be achieved through composing the proper enzyme cocktail and consequently assembling an industrial-scale microbial platform for the […]

UK and US scientists engineer enzymes to digest common plastics

UK and US scientists engineer enzymes to digest common plastics

April 17, 2018 |

In the UK, scientists have engineered an enzyme which can digest some of our most commonly polluting plastics, providing a potential solution to one of the world’s biggest environmental problems. The discovery could result in a recycling solution for millions of tons of plastic bottles, made of polyethylene terephthalate, or PET, which currently persists for […]

Bugging out over exciting enzymes found in ancient insects

Bugging out over exciting enzymes found in ancient insects

February 25, 2018 |

Ancient insects’ digestion could boost biofuel development In the United Kingdom, researchers at the University of York found that the ability of some insects to efficiently digest cellulose could be exploited for industrial processes, such as the production of sustainable low carbon fuels to cut greenhouse gas emissions associated with fossil fuel use. According to […]
