The invention concerns bacteria with improved resistance to stress with respect to the wild strain, characterised in that they contain at least one gene mutation which affects the normal activity of said gene, this gene being involved in the transport of electron, amino acids, oligopeptides, phosphate, DNA repair, the stability of RNA or of new genes and selected among: genes from GP biosynthesis, genes of the clone R1.1 (pstS), R1.4 (arl1), R1.5 (glnP), R1.7 (carB), R1.8 (glnP), R1.14 (arl2), R1.16 (glnP), R1.17 (glnQ), R1.20 (arl3), R2.6 (pstB), R2.9 (recN), R2.11 (arl4), R2.15 (arl5), R2.17 (arl7), R2.20 (arl8, yybT), pstS, pnpA, and trl1.
L'invention concerne des bactéries présentant une résistance aux stress améliorée par rapport à la souche sauvage, caractérisées en ce qu'elles comportent au moins une mutation dans un gène qui altère l'activité normale dudit gène, ce gène étant impliqué dans le transport d'électron, d'acides aminés, d'oligopeptides, du phosphate, de la réparation de l'ADN, de la stabilité des ARN ou de nouveaux gènes et choisi parmi: les gènes de la voie de biosynthèse des GP, les gènes du clone R1.1 (pstS), R1.4 (arl1), R1.5 (glnP), R1.7 (carB), R1.8 (glnP), R1.14 (arl2), R1.16 (glnP), R1.17 (glnQ), R1.20 (arl3), R2.6 (pstB), R2.9 (recN), R2.11 (arl4), R2.15 (arl5), R2.17 (arl7), R2.20 (arl8, yybT), pstS, pnpA, et trl1.
