Characterization of our biobrick ccdB

X. 01/09/14-07/09/14

We finished with a killing ccdB test for the characterization of pSB_1C3-ccdB: this is ok :)

In the two following screens (the first is with presence of glucose, the second with arabinose), the first line corresponds to $\EColi$ without Tox-plasmid and without A-Tox plasmid (no plasmid), the second to $\EColi$ with Tox-plasmid but without A-Tox plasmid (pBAD33::ccdB), the third to $\EColi$ without Tox-plasmid but with A-Tox plasmid (pKK233::ccdA), and the last to $\EColi$ with the two plasmids (pKK233::ccdA & pBAD33::ccdB). The columns vary by a dilution factor (from left to right: $10^{0}$, $10^{-2}$, $10^{-3}$, $10^{-4}$, $10^{-6}$).

$E.Coli \hspace{0.2cm}+\hspace{0.2cm} glucose:\hspace{1cm}$

$E.Coli \hspace{0.2cm}+\hspace{0.2cm} arabinose:\hspace{0.65cm}$

With these two killing assay screens, we see that the glucose represses the toxin (line two: bacteria survive)

and arabinose inducts the production of toxin, and bacteria death.
