UW-Stout/Sensitivity To Nitrogen Starvation

Growth of YEL035C on synthetic defined media (SDC).
Growth of YELO35C on omission media that lacks nitrogen.
Growth of transferred BY4735 on Synthetic defined media.

Knocking out the YGL035C seems to have no effect on growth after incubating for 5 days on the Nitrogen omitted media.

Ultraviolet Sensitivity

YEL035C is more sensitive than BY4735(wild) given that there is less colonizes present when under the same stress.

Growth Rate in YPD

In a BY4735 background, knocking out YEL035C seems to have a moderate effect on growth rate in log-phase in YPD media. In this assay, the BY4735 strain's doubling time was 124 minutes, while the YEL035C knock-out strain's doubling time was 220 minutes.

G-418 Stress

In the BY4735 background, knocking out the YEL035C strain seem to have a moderate effect on a growth rate, by slowing down the growth even more than the BY4735. In the knock-out experiment, the BY4735 strain's doubling time was 149 minutes, whereas the YEL035C knock-out strain's doubling time was 309 minutes. In the calibration experiment, the BY4735 strain's doubling time was 64 minutes, whereas the YEL035C knock-out strain's doubling time was 100 minutes.


Methanol sensitivity

The wild type strain had a little difference in the doubling time when we added methanol, but the methanol killed all of the cells in the YEL035c strain. [[1]]

Heat Shock

Stressing with Hydroxyurea

Hydroxyurea Protocol - The wild type strain had only a small difference in doubling time when stressed with Hydroxyurea; however, the doubling time of the YEL035C strain was much higher, indicating that the gene is more sensitive to the stress and that this gene probably plays a role in DNA replication.

Fermentation

Fermentation protocol link [2] - There appears to be no major difference in fermentation rate. The lower final ethanol percentage could be a result of evaporation. If this experiment were to be carried out again then it should be done in an air tight container.
