A single-celled fungus that built bread, beer, and most of biology's secrets along the way.
means Baker's yeast is a strain of the fungus Saccharomyces cerevisiae used to leaven bread, feeding on sugars and exhaling carbon dioxide that makes dough rise.
from "Yeast" comes from Old English 'gist' or 'gyst', tied to a root meaning to foam, froth, or boil — the same impulse you see in fermenting beer or rising dough, and a probable cousin of Greek 'zestos', boiled. "Baker" traces to Old English 'bæcere', one who bakes, from the same family as 'bake' itself. The scientific name says it plainly: Saccharomyces cerevisiae means roughly "sugar-fungus of beer" — a reminder that the bread yeast and the brewing yeast are kin, and that humans were harnessing this invisible froth-maker for millennia before anyone knew it was alive.
