Abstract[English]
The invention concerns a genetically modified cellulose producing bacterial strain comprising a reduction in expression of native gene encoding a ClpS polypeptide, or a deletion of the native gene encoding a native ClpS polypeptide, or comprising expressing or overexpressing a gene encoding a ClpA polypeptide containing a mutation or a deletion in the ClpS-binding region of said polypeptide, and/or expressing or overexpressing a gene encoding a ClpS polypeptide containing a mutation or deletion in the ClpA-binding region of said polypeptide, causing an alteration of binding affinity between the ClpS polypeptide and the ClpA polypeptide.[French]
L'invention concerne une souche bactérienne productrice de cellulose génétiquement modifiée, comprenant une réduction de l'expression du gène natif codant pour un polypeptide ClpS, ou une délétion du gène natif, codant pour un polypeptide ClpS natif, ou comprenant l'expression ou la surexpression d'un gène codant pour un polypeptide ClpA, contenant une mutation ou une délétion dans la région de liaison ClpS dudit polypeptide et/ou l'expression ou la surexpression d'un gène, codant pour un polypeptide ClpS, contenant une mutation ou une délétion dans la région de liaison ClpA dudit polypeptide, provoquant une altération de l'affinité de liaison entre le polypeptide ClpS et le polypeptide ClpA.
