Eleven of the nineteen promoters of the [http://partsregistry.org/Part:BBa_J23100 '''Anderson collection'''] (J23100,J23101, J23102, J23103, J23106, J23107, J23113, J23114, J23115, J23117, J23118) 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 (Fig. 1). 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 (Lumi/ OD<sub>600</sub> 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''.

The '''constitutive promoters''' P<sub>''liaG''</sub> and P<sub>''lepA''</sub> were evaluated in the reporter vector pSB<sub>Bs</sub>3C-<i>luxABCDE</i> which contains the ''lux'' operon. 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 values. All clones show a usual growth curves. The activity of the promoters raises during the pass from the transition to the stationary phase. The second clone of the promoters P<sub>''lepA''</sub> and P<sub>''liaG''</sub> did not show any luminescence activity. In the beginning of the growth curve the activity of both promoters raise to their maximum. They show a similar behaviour in pertaining to the groth curve. P<sub>''liaG''</sub> has an activity maximum of about 100.000 Lumi/OD<sub>600</sub> during the pass from logarithmic to the stationary phase. P<sub>''lepA''</sub> shows an maximum of about 400.000 Lumi/OD<sub>600</sub>. Comparing these two consitutive promotersthe activity of P<sub>''lepA''</sub> is about four times higher than the activity of P<sub>''liaG''</sub>. In the late stationary phase the activity completely disappears.

The β galactosidase assay of the constitutive ''Bacillus'' promoters Pveg and P<sub>''liaG''</sub> was repeated three times. Data show one representative result. Two undependant clones of ''B. subtilis'' with the same construct were measured and their mean with standard deviation is show in the graph. In the beginning of the growth curve both promoters show a small activity. But then it raises to a maximum bevor it decreases to the begininng level after about seven hours (Data not shown). Summing up the course of activity of both promoters P<sub>''veg''</sub> and P<sub>''liaG''</sub> is very similar based on the growth curve. The highest beta galactosidase activity and therefore the highest activity of the promoter Pveg can with an maximum of 65 Miller units be found during the transfer from the logarithmic to the stationary phase. This is about five times higher than the acitivity of the promoter P<sub>''liaG''</sub> with an maximum activity of about 12 Miller Units.

===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_bahhumbug.jpg|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''::mls, ''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|thumb|400px]]

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".
