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".

Jenny presented Bacillus germination review to the group. We discussed stages of germination & how our mutants would prevent germination from occurring. Discussed possible germination causes besides nutrients, and how to hopefully prevent them. We realized partial germination caused by biochemical reactions from nutrients might cause the spores to deform, even if they did not complete germination. Therefore Jenny began research on this possibility.
Clean deletions of germination genes sleB and cwlB from PCR accomplished. DNA purified and frozen to be later transformed with Bacillus.
β-galactosidase assays of the promoters PliaG, PliaI and Pveg are finished. Look at Data!

Promoters PliaG, PliaI, Pveg and PlepA are now in the vector pSB1C3 as BioBrick standard for the registry. BioBricks are BBa_K823000, BBa_K823001, BBa_K823002, BBa_K823003.
The Anderson promoters J23100, J23101, J23102, J23103, J23106, J23107, J23113, J23114, J23115, J23117, J23118 are now in the Bacillus reporter vector pSBBs3C-luxABCDE for measuring their activity as luminescence.

Jara created the single mutant cwlD::kan.
2-6 April 2012
Jara successfully created our first single knockouts of germination genes using a resistance cassettes: sleB::mls, gerD::cat and cwlJ::spec.
Jara tried knocking out cwlB using the kan resistance cassette. Mutants of cwlB::kan grew very poorly though.
26-30 March 2012
Jara tried knocking out cwlB using the tet resistance cassette. Mutants of cwlB::tet grew very poorly.
19-23 March 2012
We decided which genes to knock out for the germination stop. Based on the work of [http://www.ncbi.nlm.nih.gov/pubmed/19554258 J. Kim and W. Schumann (2009)], we decided to knock out genes cwlB, gerD, cwlJ, and sleB. From the research of [http://www.ncbi.nlm.nih.gov/pubmed/11466293 B. Setlow et al (2001)], we also chose cwlD.
