Yeast

[summersoon]

What else denatures (kills) yeast cells apart from high temperatures?

Does pH?

Thanks in advance x

Age also kills yeast. If you have any that has sat in the fridge for a while, "proof" it before using it.

PS. I would think that pH would also: most living organisms have an extremely narrow pH range in which they can survive.
