Figure 2. Elemental composition of the substrates I–V in terms of potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), iron (Fe), sodium (Na), manganese (Mn), zinc (Zn), copper (Cu), nickel (Ni), chromium (Cr), cobalt (Co), and lead (Pb) (mg kg−1 DM); n = 3.
Figure 3. Photos taken of Ganoderma lucidum, Pleurotus ostreatus, and Trametes versicolor after 1, 4, and 7 days of incubation at 26 °C, 80% relative humidity, in the absence of light. Substrate IDs IV and V stand for mixture ratios of 1:3 and 0:4 of pine bark and cotton fiber, respectively.
Figure 4. Radial expansion (mm d−1) of three Basidiomycota measured over seven days with 0, 5, and 10 vol.% flush of CO2 on the five different substrate mixtures with addition of 0, 2, and 5 wt.% CaCO3. Data were collected for three replicates of the experiment (n = 3) run in parallel. Radius was measured every 24 h in triplicate by the distance from the center of the inoculum to the longest visible hyphae.
