Fungi are “nature’s biological recycling machines,” says guest Vayu Hill-Maini, a former chef turned bioengineer. That is, they take waste and turn it into good things. Hill-Maini now melds his scientific and culinary skills to create new foods, but also medicines, faux leather, pigments and other valuable products from mushrooms and molds. He uses CRISPR gene editing technology to “domesticate” these fungi – removing off-flavors and increasing nutritional content to make new-age cheeses, burgers, salami, and more. “We call it the DBTL cycle – design, build, taste, learn,” Hill-Maini tells host Russ Altman about his creative process on this episode of Stanford Engineering’s The Future of Everything podcast.
