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).

===Germination Stop===
+
-
We induced our germination-mutant strains to sporulate in Difco sporulation media. Then we measured the germination rate of mutant spores in a germination assay.
+
-
 
+
-
[[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). WT168 is a positive control; ''Spo0A'' is a negative control. <br /> Strains: <br /> '''B40''' -- ''cwlD''::kan, ''sleB''::mla, ''cwlJ''::spec <br /> '''B41''' -- ''cwlD''::kan, ''sleB''::mls, ''gerD''::cat <br /> '''B42''' -- ''cwlD''::kan, ''cwlJ''::spec, ''gerD''::cat <br /> '''B43''' -- ''gerD''::cat, ''sleB''::mls, ''cwlJ''::spec <br /> '''B46''' -- ''cwlD''::kan, ''cwlJ''::spec, ''gerD''::cat, ''sleB''::mls <br /> '''B47''' -- ''gerD''::cat, ''sleb''::mls, ''cwlJ''::spec, ''cwlD''::kan]]
+
-
 
+
-
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.

iGEM Ludwig-Maximilians-Universität München Beadzillus

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".
