| − | <p>Growth kinetics was initially studied using 50 mL cultures. <b>Fig. 1</b> shows the growth kinetics of <i>E. coli</i> DH5α & derivative strains containing plasmids from the <a href="https://2015.igem.org/Team:Birkbeck/InterLab_Study">InterLab</a> study. The growth curve shows that the <i>E. coli</i> strain that contains the P1-<i>gfp</i> expression device grows at a slower rate than the other strains investigated. At 220 minutes the <i>E. coli</i> DH5α P1 strain has a significantly lower OD<sub>600</sub> than the <i>E. coli</i> DH5α (P=0.023). <i>E. coli</i> DH5α remains significantly higher in OD<sub>600</sub> than <i>E. coli</i> DH5α with the P1-<i>gfp</i> expression device (P=<0.001)<!---->. The only difference between the <i>E. coli</i> DH5α & <i>E. coli</i> DH5α positive control device is observed at 280 minutes into the growth curve (P=0.016) where the positive control has a higher OD<sub>600</sub>. The multiple comparison table showing P values can be viewed in <a href="https://2015.igem.org/Team:Birkbeck/Results/Table_S1"><b>Table S1</b>.</a></p>.

| |
| − | <p>In order to investigate if there could be a point in the <i>E. coli</i> DH5α growth curve in which a signal from the GFP could be detected by absorbance, the growth curves were also conducted using the major absorption peak of GFP (wavelength 395 nm)<!--(REF!)-->. The growth curve data for the culture optical density is displayed in <b>Fig. 2</b>.</P>
| |
| − | <p>When comparing the data point of <i>E. coli</i> DH5α strains, there appears to be a significant increase in culture OD<sub>395</sub> in the <i>E. coli</i> cells with the P1-<i>gfp</i> expression device (P<0.001). This apparent signal is only present between 60-100 minutes of growth. When comparing the positive control & <i>E. coli</i> DH5α1, there is no significant difference between the data sets at 60 or 100 minutes (P=1 for both time points). A small potential signal is observed from the oositive control <i>gfp</i> expression device at 280 minutes (P=0.012) & 300 minutes (P=0.006). This significance is lost after 300 minutes (P=0.262). See <a href="https://2015.igem.org/Team:Birkbeck/Results/Table_S2"><b>Table S2</b></a> for more details. In order to verify these results & to test for the feasibility of scaling down to a 96-well microtitre plate assay, a 10 hour growth curve was conducted in a 96-well microtitre plate (see <b>Fig. 6-8</b>).</p>

| − | <p><b><u>Fig. 3: Viable Count of <i>E. coli</i> DH5α After 60 mins</u></b>.</p>
| + | |
| − | <br>
| + | |
| − | <p>In order to assess how many viable cells correspond to different optical densities, a viable count was conducted on <i>E. coli</i> DH5α1 at 60 minutes (<b>Fig. 3</b> & <b>Table 1</b>), 175 minutes (<b>Fig. 5</b> & <b>Table 2</b>) & 225 minutes (data not shown due to high level of contamination).</p>
| + | |
| − | <p>Considering the OD<sub>600</sub> of the <i>E. coli</i> DH5α1 cultures at 60 mins, triplicate cultures were OD<sub>600</sub> = 0.029, 0.01 & 0.025<!--0.021 mean-->. The viable count of each of the cultures gave a mean of 2.57×10<sup>6</sup> cfu/mL (<b>Table 1</b>). It can therefore be concluded that an <i>E. coli</i> DH5α culture at an OD<sub>600</sub> = 0.021 corresponds to approximately 2.57×10<sup>6</sup> cfu/mL.</p>

The viable count of each of the cultures gave a mean of 1.33×10<sup>8</sup> cfu/mL (<b>Table 2</b>). It can therefore be concluded that an <i>E. coli</i> DH5α culture at an OD<sub>600</sub> = 0.244 corresponds to approximately 1.33×10<sup>8</sup> cfu/mL. Considering the previous OD<sub>600</sub> (0.021), there is approximately a 10-fold increase in OD<sub>600</sub> which corresponds to nearly a 100-fold increase in viable cells.</p>
