Figure 2.

Correlation between fungal activities and three signature VOCs detected in the headspace of the spruce wood—fungal culture flasks: (A) α-humulene and released dissolved glucose, (B) terpinolene and iron reduction capacity and (C) methyl 3-furoate and total amount of secreted proteins. In the panels, the cultivation time points at months 2 (spheres) and 3 (triangles) are depicted. Fungal species abbreviations, see Table 1.
