(A) Laccase, (B) manganese peroxidase, (C) β-glucosidase, (D) endoglucanase, (E) peptidase, (F) chitinase activities, (G) iron reduction and (H) concentration of accumulated oxalic acid in the fungal cultures on spruce wood calculated in relation to total dry weight of the culture solids at each time point (cultivation months 1, 2, 3). Mean average values (n = 3, three parallel cultures) with standard deviation are presented at each time point. * = time point 2 or 3 differs significantly (P ≤ 0.01) from time point 1, + = time point 3 differs significantly (P ≤ 0.01) from time point 2. Fungal species abbreviations, see Table 1.
