Is yeast is a bacteria?


No, yeast is not a bacteria. Yeast is a type of fungus, specifically a single-celled organism called a “Saccharomyces cerevisiae.” While both bacteria and yeast are single-celled microorganisms, they are fundamentally different in terms of their cellular structure, mode of reproduction, and other characteristics. Yeast is commonly used in baking and brewing because it produces carbon dioxide gas and alcohol as it consumes sugar, causing dough to rise and beer to ferment.
