Collaboration - Calgary iGEM

We were asked by the Calgary iGEM team to to test the viability of their chassis to survive in tailings pond water. If E. coli DH5α cells containing one of our constructs can grow normally in medium prepared with tailings water, we can be confident that the chassis can be applied to tailings pond water in general.

Materials and Methods

50 mL of LB medium was made with tailings water and filtered through MILLEX filter Unit GS MF-Millipore MCE Membrane 0.22 µm in order to sterilize it and appropriate antibiotics were added. The tailings LB was inoculated with E. coli DH5α cells containing BBa_K331009 to an OD600 of 0.1. The flask was incubated at 37˚C with shaking for 7 hours, during which photometric readings were taken every 30. Photometric readings were taken using the Pharmacia Biotech Ultrospec 3000, as the OD600 readings reached 1.0 the solutions was diluted with LB media to keep the OD600 reading between 0.1 and 1.0. The same protocol was used to observe cell growth of E. coli DH5α cells containing BBa_K331009 in 50 mL of LB medium made with MilliQ H2O.

Figure 1. OD600 of E. coli DH5α cells containing BBa_K331009 cultured in LB medium made with tailings water (red) and LB medium made with MilliQ H2O (black).

Conclusion

As seen in Figure 1, E. coli DH5α cells were able to grow in LB medium made with tailings water, suggesting that the chassis will survive for use in tailings pond water.
