I needed an image of wt yeast in DI YPD to compare with the morphology of later strains. As I ramp up the D2O concentration, I expect to see some differences and this is good information to have in general.

I don’t think there is much to infer from the 20% D2O comparison image, but if it’s worth anything there are a few cells in that image that are elongated, and I never saw that morphology in DI water.
