* % Area is given as the area of the peak of interest over total area of peaks in chromatogram (from 3 replicate EC-12 cultures grown in potato dextrose (PD1-PD3)). Only compounds with quality match scores >70 are listed. Area of unassigned peaks are summed and listed as unknown compounds. Compounds also observed in PD broth control are italicized, (nd) = not detected. Details of VOC extraction and GC/MS analysis are in Methods section.
