Total amount of (A) ergosterol, (B) secreted proteins and (C) dissolved nitrogen measured in the culture extracts during three months, at each time point 1, 2 and 3 months of fungal growth on spruce wood. 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.
