Fungal growth and extracellular protein concentration of P. chrysosporium. a Fungal growth and b extracellular protein concentration of P. chrysosporium cultivated for 3 days in synthetic medium containing 2.0% (w/v) UB (white circle) and 2.0% (w/v) AB (black circle) as carbon sources. The mycelium volume per 1 mL of culture filtrate was measured as described in Materials and Methods. Protein concentration of the culture filtrate was estimated by the Bradford method. UB untreated birch wood meal, AB ammonia-treated birch wood meal. Each data point represents the mean ± standard deviation (SD) of three replicates. Where the error bars are not visible, they fit within the symbols
