The videomicroscopy indicates that blue light with a wavelength around 500nm leads to CheA's autophosphorylation being downregulated. This means that the bacterial tumbling frequency gets reduced and the bacteria will spend an increased time in the "run" mode of propulsion. This means that the bacteria will travel further in a certain amount of time, compared to wildtype bacteria. More details can be found here [http://2010.igem.org/Team:SDU-Denmark/project-p#K343007| Characterization - K343007 - 2. Videomicroscopy and computer analysis of bacterial motility]<br>

The growth assay showed no significant difference between the wild type and the cells transformed with the biobrick.
Regarding the stability of the plasmid, we carried out a stability assay according to protocol [http://2010.igem.org/Team:SDU-Denmark/protocols#SA_1.1|SA1.1] There was no observeable difference between the cultures plated out on plates with and without antibiotics. From this we conclude that the plasmid does not significantly increase the stress on the bacteria, since they don't seem to lose the plasmid after 5 days. Since this did not happen the plasmid seems to be stable. For a closer look at the results look here:
