What is yeast? And where to find it naturally?

507 viewsBiologyOther

What even is yeast? I am thinking mainly of the kind we use to make bread rise. Which I buy from the grocery store…

But, back in the day, where did people find yeast? I assume people cultivate it and grow it, much like sour dough, but someone had to find it originally, right?

And what does ir do in the wild? Especially since it is so easy to kill? (Can’t be too hot, can’t touch salt, can’t be too old…)

Note: this is purely to do with my curiosity. I have no interest in actually hunting wild yeast

To make bread you just need a shallow bowl full of water with a little flour, left somewhere dark and warm. After a day or two it will start bubbling. Now add the rest of the flour, knead, and let it rest for a few hours. Ready to go.

Only problem is, you have no idea what kind of yeast your using, or what other microbes are growing in the mix.
