===15 Promoters evaluated in ''B. subtilis'' and added to the registry!===

<p align="justify"> This section gives an overview on the strength of all evaluated promoters, which span a large range of activities. For more details and informations of the experiments see the [https://2012.igem.org/Team:LMU-Munich/Data Data] page of the promoters. Note that P<sub>''veg''</sub> was not evaluated with luminescence measurements and this bar is just projected from the results of the β-galactosidase assay.</p>

<font color="#000000"; size="2"><p align="justify"> '''Overview of promoter activity evaluated with luminescence measurements in pSB<sub>''Bs''</sub>3C-''luxABCDE''.''' These values derive from the experiments you can find in our Data section. Lumi per OD<sub>600</sub> are taken at a OD<sub>600</sub> of 0.1. Values are the average and the standard deviation of three different experiments for clone 1. Shown is the activity of the Anderson promoters J23100 (#100), J23101 (#101), J23102 (#102), J23103 (#103), J23106 (#106), J23107 (#107), J23113 (#113), J23114 (#114), J23115 (#115), J23117 (#117), J23118 (#118) as well as the activity of the constitutive promoters P<sub>''liaG''</sub>, and P<sub>''lepA''</sub>. The activity of the inducible promoter P<sub>''liaI''</sub> is shown with (+bac) and without (-bac) induction with bacitracin (10 μg/ml). The promoter activity of P<sub>''veg''</sub> is projected from the results from the β-galactosidase assay and was not measured with luminescence measurements. For the assays shown, an intermediate version of the reporter vector pSB<sub>''Bs''</sub>3C-''luxABCDE'' was used, which still contained one forbidden PstI site.</p></font>

Team-LMU red and white.resized.jpg

The LMU-Munich team is exuberantly happy about the great success at the World Championship Jamboree in Boston. Our project Beadzillus finished 4th and won the prize for the "Best Wiki" (with Slovenia) and "Best New Application Project".
