Concentration of phenolic compounds in whole extractives of wood samples. P. carnosa (lines) and P. chrysosporium (white) were grown on heartwood (A) and sapwood (B) wood samples at 27°C. P. carnosa grew significantly slower than P. chrysosporium, and so samples were taken for analysis after 42 and 18 days of cultivation for P. carnosa and P. chrysosporium, respectively (for colony diameter, see Additional file 3: Figure S6). Grey bars indicate the phenolic content of wood samples prior to fungal cultivation. The amount of phenolics in total extractives was measured using the F-C reagent method and calculated as percent concentration . Gallic acid was used to generate a calibration curve. Error bars show the standard deviation in biological triplicates.
