Episode 8: The Genomics of Lactic Acid Bacteria

Introduction: The Genomics of Lactic Acid Bacteria: From Fermentation and Probiotics to the Microbiome and CRISPR

For many centuries, fermented foods like cheese, yogurt and kefir have relied on lactic acid bacteria (LAB) for their flavor, nutrition, texture and shelf life. The art of fermentation has now become a science through genomic sequencing of LAB, which has improved the stability of the fermentation process and yielded insights into the probiotic properties of fermented foods and their interaction with the human gut and microbiome.

Host:

Allen

E. Allen Foegeding E. Allen Foegeding is a William Neal Reynolds Distinguished Professor of Food Science at North Carolina State University. He started at N. C. State University in 1982 after completing his Ph.D. at the University of Minnesota. His career has focused on advancing the understanding of chemical and physical properties of foods through teaching and research. Allen has taught courses in Food Chemistry, Muscle Foods, and Colloidal and Polymer Properties of Foods. His research has provided insight into how food biopolymers function in foods, with a focus on whey proteins in forming sols, foams, and gels. Allen is a fellow in the Institute of Food Technologists, the Agricultural and Food Chemistry Division of the American Chemical Society, the Royal Society of Chemistry (UK), and the American Association for the Advancement of Science. In 2016 he received the Nicolas Appert Award for preeminence in and contributions to the field of food technology.
