Back in the day I was calling the bacteria grown here D2O adapted yeast. Boy was I stupid. Anyway, here is the data I took when trying to compare the morphologies. Despite my naivety, I think there can be interesting studies done with E. coli in D2O based on these experiments and the colony morphology experiments I did.
Also I’ve included actual yeast in D2O images, which show that yeast form “chain gangs.” Basically the buds never seal off and grow new buds and large clusters of bud chains grow. Hopefully I can analyze this more in the upcoming experiments.
