The Science of Yeast, the Microbe in your Pandemic Bread

/ / Businesss, Science

Humans have been baking fermented breads for at least 10,000 years, but commercial yeast and flour companies have never seen demand so high. National Geographic shares “a story for quarantined times, about extremely tiny organisms that do some of their best work by burping into uncooked dough.”

Scientists describe the microbes behind the work fermenting the bread. “It’s this wonderful living thing you’re working with,” says Anne Madden, a North Carolina State University adjunct biologist who studies microbes. She and partner scientists showed recently that when bakers in different locales use exactly the same ingredients for both starter and bread, their loaves come out smelling and tasting different. “Which I think is fantastic,” she says. “It’s evidence of the unseen. And as a microbiologist, you so rarely get to measure things about microbes with your nose and your taste buds.”
