Episode 8.1: Exploring killer yeasts

Meet Paul Rowley, an associate professor in the Department of Biological Sciences at University of Idaho. Yeasts are the basis of our breads and brews, but Rowley looks deeper into the secret lives of yeasts and how they interact with viruses and other fungi.

Have you ever tried baking or brewing with yeast?

Rowley takes listeners on a journey into the fascinating world of yeast. While commonly associated with baking and brewing, yeast has a far more complex role in science. Rowley’s research focuses on yeast’s interactions with viruses, revealing how these microorganisms engage in a microbial arms race. Yeast can harbor viruses that don’t harm them but instead enable the production of antifungal toxins, which fend off competing strains. This relationship challenges the perception of viruses as solely harmful, showcasing how they can benefit their hosts. Rowley also discusses practical applications of his work, including solutions for diastatic yeast contamination in brewing, which can cause dangerous carbon dioxide buildup in sealed bottles. By collaborating with industry partners like Rhinegeist Brewery, his lab is exploring how “killer yeasts” might revolutionize brewing. Beyond brewing, his research has implications for human health, particularly in combating fungal infections. The episode highlights the importance of basic science, student involvement and unexpected discoveries in microbiology.
