synthèse de rna stables dans une souche d'escherichia coli stringent pendant la carence en acide aminé spécifiqueNA synthesis does not stop and this result showed that RNA synthesis is not a coordinated process. Tdoi:10.1111/j.1432-1033.1970.tb00928.xGalibert F...
Colibactin is a genotoxin that contributes to the virulence of extra-intestinal pathogenic Escherichia coli and promotes colorectal cancer. In this work, we examined whether the pks-encoded clbS gene of unknown function could participate in the self-protection of E. coli-producing colibactin. A ...
The D-values of E. coli O157:H7 at 55–62.5 °C in samples without CP or CSO ranged from 11.64 to 0.99 min. In samples with CP or CSO, D-values ranged from 10.59 to 0.35 min and 11.11 to 0.41 min, respectively. The effect of CP and CSO on D-values was temperature-dependent. ...
Finally, the deuterated E. coli were used to verify the potential antibacterial effect of a marennine-like pigment produced by marine microalgae. We were able to detect a different perturbation of the bacteria membranes by intra- and extracellular forms of the pigment, thus providing valuable ...
