Cellulase promotes the mycelial growth of F. filiformis. a Changes in mycelial growth rate on the 0, 0.3%, 0.6%, 0.9%, and 1.2% cellulose medium for 8 d. b Cellulase activity of mycelia cultured on the medium with 0, 0.3%, 0.6%, 0.9%, and 1.2% cellulose for 8 days. c Mycelial growth in the 0.9% cellulose medium for 3, 4, 5, 6, 7, and 8 d. d Cellulase activity of mycelia cultured on the 0.9% cellulose medium for 4, 5, 6, 7, and 8 d. Each value represents the mean ± SD (n = 3), and different lowercase letters denote statistical significance (P < 0.05)
