Cheese Rind In Situ-In Vitro Model Community

A tractable fermented-food surface biofilm system based on cheese rind microbial communities. Wolfe and colleagues surveyed 137 rind communities across 10 countries, isolated representatives of the dominant bacterial and fungal genera, and reconstructed simplified cheese-curd-agar communities in vitro to test how moisture, washing, pH, and bacterial-fungal interactions shape reproducible community assembly and succession.
