The yeast Saccharomyces cerevisiae is found in beer, wine, and bread, but also in research laboratories, as it is the organism that initiated modern biochemistry and molecular biology and remains a fundamental testing ground for science.
Yeasts are more diverse than we think; there are thousands of species and they inhabit almost all natural environments on the planet, being used in food production and/or to produce antioxidant compounds and sunscreens.
