UW-Stout/Sensitivity To Nitrogen Starvation

Growth of YCR100C on synthetic defined media (SDC).
Growth of YCR100C on omission media that lacks nitrogen.
Growth of transferred BY4735 on Synthetic defined media.

Knocking out the YCR100C seems to have no effect on growth after incubating for 5 days on the Nitrogen omitted media.

Growth Curve

In a BY4735 background, knocking out YCR100C seems to have a moderate effect on growth rate in log-phase. In this assay, the BY4735 strain's doubling time was 124 minutes, while the YCR100C knock-out strain's doubling time was 219 minutes.

Ultraviolet Sensitivity

YCR100C is more sensitive than BY4735(wild) given that there is less colonizes present when under the same stress.

G-418 Stress


In the BY4735 background, knocking out the YCR100C strain seem to have a very small effect on a growth rate by slowing it down. In the knock-out experiment, the BY4735 strain's doubling time was 149 minutes, whereas the YCR100C knock-out strain's doubling time was 235 minutes. In the calibration experiment, the BY4735 strain's doubling time was 64 minutes, whereas the YCR100C knock-out strain's doubling time was 92 minutes.

Methanol Sensitivity

The wild type had a doubling time of 150 min, the YCR100c had a doubling time of 350 min. The methanol slowed the yeast down and that means this strain is more sensitive.

Heat Shock

YCR100C Heat Shock.PNG Heat shock had no change on the doubling time, but the starting amount of yeast cells less. The heat seemed to kill off the cells, the longer they were in the hot water bath.

Stressing with Hydroxyurea

Hydroxyurea Protocol -The wild type strain had only a small difference in doubling time when stressed with Hydroxyurea;YCR100C showed about a 20 minute difference in doubling time when stressed with hydroxyurea, indicating that this gene most likely does not play a vital role in DNA replication.

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.


Caffeine Sensitivity

YCR100C VS BY4735 CAffeine PRotocol UW-Stout/Caffeine YCR100C and the Wild Type yeast had a very similar reaction to the caffeine.
