DVB/CAR/PDMS SPME fiber was used. The values represent the average of the same compound produced by 5 strains (each analysed by four vials) that belong to the same species (A. pullulans, A. melanogenum, A. subglaciale). Different letters represent significant differences among the species for each compound according to Tukey’s HSD Test (α = 0.05)
