Biofilms (featuring Dr. Katrine Whiteson)

Biofilms are microbial communities encased in a self-produced matrix that form on surfaces, representing the dominant mode of microbial life in nature. They play roles in everything from kombucha fermentation to fossil preservation and chronic infections. Dr. Katrine Whiteson discusses using bacteriophages to target dangerous biofilms, highlighting their ecological and medical significance.

You’ll gain a deeper understanding of how microbial communities shape health, disease, and even the fossil record—with real-world implications from your kitchen to the clinic.

1. 01Biofilms are structured microbial communities that provide protection and resource-sharing advantages, making them far more resilient than free-floating (planktonic) bacteria.
2. 02Fermented foods like kombucha rely on visible biofilms (e.g., the SCOBY) to convert sugar into flavorful organic acids, demonstrating beneficial biofilm applications.
3. 03Phage therapy is being explored to disrupt pathogenic biofilms in chronic infections, offering a promising alternative to traditional antibiotics.
