Since such organisms (simple yeasts or bacteria) would carry a brand-new genetic code, they would in effect be new life forms.

ECONOMIST: A new kind of DNA

Ale is how beer was made for millennia--natural yeasts in the air attacked the blend of water, hops and malted barley and started the fermentation process.

FORBES: Coolest Beers

This gave birth to something new, because the chilled-out, slower-working yeasts produced a stable beer at lower alcohol levels, and the summerlong aging blended and mellowed the beer's flavors.
