Microbioal Biogeography of Northeast Cheese Caves
CURRENTLY ONGOING
SURVEY of MYCOLOGICAL GROWTH and MICROBIALLY-RELEVANT ARCHITECTURAL CONDITIONS
ACROSS CHEESE CAVES in the US NORTHEAST
COLLABORATION WITH WOLFE LAB (TUFTS UNIVERSITY)


Boston / 2019
Working with mycologist Megan Biango-Daniels in the microbial ecology group at the Wolfe Lab, I am in the pilot stage of an observational study of fungal growth on the walls of cheese aging facilities. This study will track potential correlations between patterns of growth and underlying construction, maintenance and cleaning practices, and interior environment conditions like temperature and humidity. Perhaps more fundamentally, we are also working to test a range of methodologies for collecting this data and systematizing a microbially-relavant charactization of cheese buildings, to begin stabilizing a set of the most significant architectural and building science metadata to track in characterizing the microbial life of building, to allow for more systematic comparison of growth across different locations.

SPECULATION
Traditionally, cheese caves have had thick, heavy, porous walls, made of materials like stone, earth, or more recently, concrete. Thick, porous walls help to buffer the cool and humid conditions needed for aging cheese, making caves a natural choice for early cheese makers. In the US today, many cheese makers use thin, hollow wall assemblies, layered with an impermeable surface coating on the inside. This helps keep aging rooms easy to clean, but leaves operators reliant on mechanical services for temperature and humidity control, as well as vulnerable to condensation and moisture migration inside of layered wall assemblies. In this work, I hope to better unpack and qualify the trade-off’s between these two construction types, layered and monolithic, to help food makers choose the best architectural strategy for their operations.
