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. |
