Wild Escherichia coli are superbly adapted to survive in the intestines of their mammalian hosts and in the environment. E. coli K12 derivative (MG1655) encodes 4288 potential genes that provide the background genetic framework of this species. Particular E. coli clonal types encode additional chro...

E. coli K12 MG1655 in [34]).Since RpoS is a global regulator affecting the expression of many genes, it is difficult to speculate on the specific adaptive effects of reduced RpoS activity. It is likely that only a subset of the gene expression changes elicited by reduced RpoS activity are...
coli K12-MG1655 chromosome, and established a single-sncRNA gene knockout library. By systematically screening the sncRNA mutant library, we show that the sncRNA GcvB is a novel regulator of acid resistance in E. coli. We demonstrate that GcvB enhances the ability of E. coli to survive low...
coli K12 MG1655 and E. coli W were grown in LB broth or on LB agar plates supplemented, when needed, with appropriate antibiotics (ampicillin 100 μ g mL−1 (ap), kanamycin 25–50 μ g mL−1 (km), chloramphenicol, 20–30 μ g mL−1 (cm), and gentamycin, ...
coli MG1655 wild-type strains (Additional file 1: Table S2). While the flux from pyruvate to acetyl-CoA remained largely the same in all strains, acetyl-CoA was utilized very differently in our strain when compared to wild-type cells. Sy504 produced nearly 50% less acetate, and condensed ...
The RecA effect on swarming motility is not restricted to theE. coliMG1655 strain The ability ofE. colistrains to swarm on semisolid surfaces was initially described by Harshey and Matsuyama in 1994 [5], and has been studied intensively in the RP437 strain [6]. To know whether the effect...
