Anne Arnold Madden is an American biologist, inventor, and science communicator who advocates for finding "microbial solutions to human problems.
"[1] Madden’s research on microscopic life is often featured in the press, particularly her studies on the microbial community of food,[2][3] using advanced DNA techniques to create the first atlas of arthropods in USA homes,[4][5][6] investigating the microscopic life in dust,[7] and using insect yeasts for ethanol production and beer brewing.
[8][9][10][11][12][13] Her research on insect-associated microorganisms lead to a patent application on the use of the yeast Lachancea thermotolerans for beer brewing[14] and the first commercialization of primary souring yeasts for making sour beer.
Madden discovered and named the species Mucor nidicola, a fungus that lives inside the nests of wasps.
[19] She was featured in the award-winning science documentary film "The Kingdom: How Fungi Made Our World.
