LB medium containing ampicillin was inoculated with the over night culture and shaken until an optical density of 0.6-0.8 was reached. Meanwhile ampicillin containing M9 agar plates were prepared and autoclaved Whatman Filter Papers were imbued with tryptone solution. Then the cultures were dropped on the agar at a distance of 1 cm to the paper. On each plate also colonies hosting the empty vector pUC18 were dropped in order to have a reference. Two drops were rather applied into the agar than onto as done before, because some paper predicted faster motility. Also this time each plate was prepared in duplicates.<br></li> | LB medium containing ampicillin was inoculated with the over night culture and shaken until an optical density of 0.6-0.8 was reached.

| - | Here again a certain diversity in the growth rate could be observed. Whereas some cultures had already reached and optical density of 0.8, others were still at merely 0.04.Here again <i>fliC</i> featured a low density, this time in all strains and DH10B and BL21 show a general decreased growth rate. Striking is the fact that the strains that featured the best motility as well as the construct that seems to have the biggest influence show decreased division rate. Whether this phenomenon is a coincidence or not we are not sure about yet. | + | Here again a certain diversity in the growth rate could be observed.

Neither chemotaxis nor swimming could observed. Almost a weak later (30th of July) still no swimming nor chemotaxis had taken place, solely growth. However, the two colonies that had been applied into the agar not onto featured little swimming. Nevertheless, also these results are lousy considering the long time span. </li> |
