FIG 1.

(A) Phylogenetic tree of P. fraxinea species, including five strains, SS1 to SS5, isolated from a P. fraxinea fruiting body, using the ITS region sequences. (B) Time course of mycelial growth of the five P. fraxinea strains SS1 to SS5 grown on agar plates. (C) Major wood polysaccharide-degrading activities in the culture supernatants of the five P. fraxinea strains grown in liquid culture containing poplar wood powder as a sole carbon source for 7 days. PASC cellulase activities and xylanase activities are shown on the left and right, respectively. The averages and standard deviations were calculated from three independent biological replicates. Student’s t test was performed.
