Meet The Microbiologist - The Scientists Behind The Microbiology

Cheese rinds contain microbial communities that are relatively simple to study in the lab while offering insight into other, more complex microbial ecosystems. Rachel Dutton discusses her work studying these cheese microbiomes, one of the few microbial ecosystem types where almost all of the microorganisms are culturable.

Like all biofilm communities, architecture and spatial structure are important for microbial interactions on cheese rinds, as are oxygen gradations, food access, and proximity to m
