Model for acid-tolerant yeast helps guide industrial organic acid production

Microbes and other microscopic organisms could serve as sustainable ‘factories’ to create many types of industrial materials because they naturally convert nutrients such as sugars into byproducts. However, creating industrial amounts of organic acids from renewable resources poses a challenge, because not many organisms can grow in highly acidic environments. With the help of gene editing and computational modeling tools, a team of researchers explored one type of yeast that could survive in the harsh environment created by acidic products.
