Non-adapted yeast grown on D2O YPD Agar

The yeast colonies grown in D2O agar are finally big enough to compare to the other samples. It took almost a week to grow this much!

Up above is an image of a single colony, and another of a few colonies that have merged together. It seems that in the presence of D2O, the colonies grow quite smooth still, but a little asymmetrically. Since we know (from unpublished research) that D2O stabilizes microtubules, it would be interesting to compare these results with the morphology of colonies grown in taxol (a cancer drug known to stabilize microtubules).
