While the rind and curd microbiota have been characterized separately, there is limited information on how the structure and function of microbial communities in rinds and curds vary within and amongst cheeses. To better understand the differences in community structure CORRESPONDING and function between communities of cheese rinds AUTHORS and curds, we combined culture-based methods with culture-independent community profiling of curds and Vanja Klepac-Ceraj* rinds. Rinds contained greater taxonomic diversity than [email protected] curds. Lactobacillales dominated curd communities while members from the order Actinomycetales were found in high abundance in rind communities. Communities Celeste Peterson* varied more between rinds and curds than among [email protected] cheeses produced from different milk types. To better understand microbial community functions, we cultured and assayed isolates for antibiotic susceptibility and carbon source utilization. Among European and U.S. KEYWORDS cheeses, 70% of all susceptible isolates were cultured from U.S. cheeses. Overall, our study explored the • cheese microbiome differences within and between rind and curd microbial • rind communities of natural rind cheeses, provided insights • curd into the environmental factors that shape microbial • diversity
