Results Summary
Survival of yeast in urine
An initial test was performed in order to test the survival of yeast cells in urine, which is an important property of our biosensor if it should function as a pregnancy test. Pre-cultures of a normal lab yeast strain were prepared in 5ml YPD and let grown O/N at 30 °C. The day after, the cells were centrifuged, resuspended in 40 ml YPD and 40 ml filter sterilized urine respectively and grown in shake flasks at 37°C. OD600 measurements were taken at different points of time during the day, and the values can be seen in Figure 1. The cells in urine did not grow; the OD remained the same during the whole day, while the cells in YPD grew very well.
