Eleven (J23100,J23101, J23102, J23103, J23106, J23107, J23113, J23114, J23115, J23117, J23118) of the nineteen promoters of the [http://partsregistry.org/Part:BBa_J23100 '''Anderson collection'''] were evaluated in the reporter vector pSB<sub>''Bs''</sub>3C-''luxABCDE'' from the BioBrickBox containing the ''lux'' operon as a reporter for promoter activity. The gene expression which correlates to the promoter activity leads to the expression of the lux operon with the luciferase. The luminescence which is produced by the luciferase can be measured with the plate reader (BioTek). Data derive from three undependant measurements. Curves were fitted over each other (t=0, OD<sub>''600''</sub>=0,3) and smoothed by taking average of three neighboring values. OD<sub>600</sub> values shown are plate reader units and about one third of the usual OD<sub>600</sub> values. All clones show a usual growth curves. The activity of the promoters raises during the pass from the transition to the stationary phase. This maximum (t=1h) reaches from 200Lumi/OD<sub>600</sub> (promoter J23115) to a maximum of 1500 Lumi/OD<sub>600</sub> for the strongest promoter (J23101). Afterwards the activity goes down to the beginning level (t=2h). The oscillation of luminescence in the beginning of the curves are due to the small OD<sub>600</sub> and do not mean a high promoter activity. The luminescence of one clone of the promoters J23107 and J23114 do not show activity where in future a second clone with promoter activity should be measured. In comparison to all the other evaluated ''Bacillus'' promoters these Anderson promoters showed a very low acitivity in ''B. subtilis''.

To measure the activity not only with the ''lux'' reporter operon, four promoters of the Anderson collection were cloned into the reporter vector pSB<sub>''Bs''</sub>1C-''lacZ'' to do β galactosidase assays and then to compare the results of the strength of these promoters in ''B. subtilis''.
