MS1 collected on qTOF, UPLC C18 gradient of 10-100% ACN over first 12 minutes, held at 100% ACN for minute 12-14. Fungi and Bacteria grown alone and pairwise on Cheese Curd Agar, naming is fungi first then bacterial partner (if it is a pairwise culture), then biological replicate number. CCA = cheese curd agar media control Ecoli = E. coli K12 JB418 = Pseudomonas psychrophila sp. JB418 12 = Penicillium solitum SAM = Penicillium camemberti RS17 = Penicillium atramentosum Fus = Fusarium domesticum JB370 = Scopulariopsis strain JB370 1655 = Scopulariopsis strain 165-5 Can = Candida catenulata Deb = Debaryomyces hansenii
