Re: [DIYbio] Hacking yeast to produce high CO2 / low ethanol

Have you considered just providing the yeast oxygen? The yeast only begin creating alcohol at the end of their life cycle in an attempt to survive the oxygen free environment they've created through oxidative respiration. If you provide them oxygen, they should continue to break down your food (sugar, wheat, rice, etc.) in their usual way.

This is going to change the acidity levels at the end, and probably your taste profile along with it - not to mention you're skipping 'fermenting' as a whole.

Does this answer your question?

Can you explain a bit more about what you mean?

hmm, I thought that was affected by respiration vs fermentation, so
presumably you could look into breaking fermentation or mutants
other's have made like this.
