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).

To measure the activity not only with the lux reporter operon, four promoters were cloned into the reporter vector pSBBs1C-lacZ to do beta-galactosidase assays and then to compare the results of the strength of these promoters in B. subtilis.

[[File:germination_assay_plates_720_.jpg|frame|Fig. 5: Comparison of colony growth on LB-agar (plus antibiotics) plates. Upper plates are plated with DSM cell/spore cultures that have been heated at 80°C for 1 hour to kill living cells (but does not affect spores). This prevents cells from forming colonies. Therefore, all colonies observed are from germinated spores. Lower plates contain cultures which have not been heated. Growth on these plates is from either cells or spores, and demonstrates that strains are able to grow. WT168 has no germination knockouts; strains B40-B43 have triple knockouts; strains B46 and B47 have quadruple knockouts; ''Spo0A'' has a knockout of the sporulation gene ''Spo0A'' (replaced with a tet cassette).

The plate growth demonstrates the inability of our mutant spores to germinate. We can say that  fewer than 1 out of 3x10^7 spores of strains B40, B41, B43, B46, and B47 germinated.

Team-LMU Photo2.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".
