If bacteria produce ethanol through fermentation, and ethanol can kill bacteria, why are they not killing themselves with their own ethanol?

Question

If bacteria produce ethanol through fermentation, and ethanol can kill bacteria, why are they not killing themselves with their own ethanol?

Answer 1

We produce CO2 and CO2 in large enough concentrations will kill us. Same difference.

Also, it does kill them (yeast, not bacteria), which is why alcohol can only be fermented to a certain volume before it needs to go through distillation.
