This experiment went much better and more predictably. Yeast (unlike E. coli) is more sensitive to deuterium content and grows accordingly. Interestingly (in this experiment) the DDW sample exhibited more growth. I’ll have to experiment on this a bit more.

It should be noted that while it appears that pure D2O grows much slower than the rest (cause it does), I also started with a much lower amount of cells. The cells did not grow well in the starter culture, and they didn’t grow well here either. See the data (or the live results) for starting absorbance readings.
