FIG 3 — Nonmetric multidimensional scaling (NMDS) illustrates the differentiation of actinobacterial VOC emission profiles. Each point depicts the Jaccard distances between VOC profiles of strains grown on GA and ISP2 media (a and b) and on ISP2 medium (c) and GA medium (d) alone. Strains that did not grow on a given medium type and strains that produced no detectable VOCs were removed to minimize distance in the matrix. Points are colored to reflect the variation explained by medium type (a) and by taxonomic assignment at the family level (b to d) according to the key.
