Diapositive précédente Diapositive suivante Institute of Biosciences and Biotechnologies of Aix-Marseille Green Solutions for Tomorrow The Aix-Marseille Institute of Biosciences and Biotechnologies (BIAM) is interested in the responses of living organisms to environmental constraints, and in the mechanisms of conversion of solar energy into a biomass rich in energy. It develops biotechnologies aimed at preserving […]

Soil bacteria preserved from uranium ion toxicity by a uranium-iron binding protein

collaboration involving the CEA-BIAM and the CEA-Joliot has revealed a mechanism that would allow soil bacteria to protect themselves against uranium in the environment. Access of the radionuclide to the cell would be blocked by a protein capable of binding not only uranium but also iron. Figure 1 : les souches ViU2A, HG3 et A9 […]

Bacterial radioresistance: Zinc, a precious metal!

After having characterized in 2014 and in 2019 the pair of proteins offering Deinococcus bacteria an extreme resistance to radiation, BIAM researchers have just discovered that the molecular signal serving as a switch to this resistance process is a metal, Zinc! This mechanism would also contribute to the virulence of certain pathogens. A discovery that […]

Functioning of a key photoenzyme decrypted

The functioning of the FAP enzyme, useful for producing biofuels and green chemistry, has been deciphered. This result mobilized an international team of scientists, including many French researchers from CEA, CNRS, Inserm, École Polytechnique, the universities of Grenoble Alpes, Paris-Saclay and Aix-Marseille, as well as the European Synchrotron and the Synchrotron SOLEIL. This discovery is […]
