The microbiome of fermented foods, like any microbiome, is a multi-species microbial community and can include a rich mixture of bacteria, fungi, and yeast all in the same fermented food. The presence of a specific microbe cannot always predict the final quality, safety, or flavor of a fermented food, but studying their interactions gives a richer understanding of these community dynamics. Ben Wolfe, an Associate Professor in the Department of Biology at Tufts University has been exploring...

Along with bacteria and yeast, fungi play an important role in fermentation. We primarily think of Aspergillus oryzae and Rhizopus oryzae, but there are a number of other fungi that are used in food production, including Aspergillus sojae, Monascus purpureus. We wanted to talk to Dr. Vayu Hill-Maini, postdoctoral Fellow at the Joint Bioengineering Institute at University of California Berkeley, working in the lab of Jay Keasling, who has been approaching research into filamentous fungi in two...

One of the most well recognized microbes in food fermentation is Lactobacillus delbrueckii subsp. bulgaricus, used to produce most yogurts today. Originally named Bacillus bulgarian, the name plays homage to Bulgaria where it was first isolated in 1905. But before we isolated this microbe and cultured it to use as a starter, how was yogurt made? With the help of Sevgi’s family and insight from the rest of the community, Sevgi, Veronica and David traveled to Nova Mahala, Bulgaria to explored...

Dr. Rob Dunn is an an evolutionary biologist, currently a professor at both the Center for Evolutionary Hologenomics at the University of Copenhagen and in the Department of Applied Ecology at North Carolina State University, where he holds the title of Senior Vice Provost for University Interdisciplinary Programs. He discusses the evolution of flavor and fermentation practice.

Dr. Maya Hey is a researcher at the Centre for the Social Study of Microbes, based in the University of Helsinki. She has been studying fermentation and health for the past 15 years and holds degrees in nutrition, food studies, and communications.

Alex Hozven has been fermenting and innovating at The Cultured Pickle Shop in Berkeley for over 25 years with her husband, Kevin Farley. Her experience gives her keen insight into how consumer perception of fermented foods has changed, where the field is going, the regulatory landscape for smaller producers, and how fermented foods can be used to build community.

Dr. Evans is a Senior Researcher and Leader of the Sustainable Food Innovation Group at the Center for Biosustainability at the Technical University of Denmark. His multidisciplinary group uses culinary research & development to make flavorful, sustainable, often fermented foods, scientific methods to study their flavor, ecology and evolution, and social science and artistic practice to understand and experiment with how they might fit into food culture.In his talk, Dr. Evans shares some...

Dr. Devkota is an Associate Professor at the Cedars-Sinai Division of Gastroenterology and the Director of Microbiome Research at the F. Widjaja Foundation Inflammatory Bowel and Immunobiology Research Institute. Her research investigates the relationship between diet and the gut microbiome, with a particular focus on IBD. Dr. Devkota offers a valuable perspective on the current role of fermented foods in a clinical setting, addressing important questions such as which fermented foods are...

In this first talk, David Zilber presents a framework through which to consider fermentation and health research.
