This is my set up for yeast starters. I generally run the air for an hour or two. Just out curiosity I was wondering what would happen if I were to leave the air on the entire day it is on the stir plate? I know I am unlikely to go above 8ppm of O2 in solution, however would the yeast gorge themselves during the cell splitting stage? In other words, should the yeast uptake as much oxygen as necessary would they continue to uptake? I know too much oxygen in solution can be a problem, but if the yeast metabolizes the O2 can introducing more have an affect?
Continuing the logic to absurdity, If I left the pump on even after the starter wort was completely fermented, would there be any down side other than the obvious staling consequences?
To be clear, I am on a stir plate with a typical aquarium air pump running threw a hepa filter.
