The remarkable genomic evolution of cheese and wine yeasts

Bread, wine, cheese, rum or oak bark…. How has the Saccharomyces cerevisiae yeast shaped its genome to adapt to these different environments? An international team led by scientists from INRA, working in collaboration with CEA, has compared the genomes of 82 strains of this yeast. They have revealed strikingly specific features concerning the strains isolated in wine and cheese.

When Listeria monocytogenes goes to sleep….

INRA* scientists, working in collaboration with their colleagues at Institut Pasteur**, have demonstrated the novel capacity of L. monocytogenes to generate dormant intracellular forms that could be harboured, unsuspected, by their host. These findings are published on 30th November 2017 in PLoS Pathogens.
