Two different media were prepared to assess the ability of isolates to utilize cellulose: (i) CMC agar medium and (ii) CMC Congo red agar medium. CMC agar consisted of 0.2% NaNO3, 0.1% K2HPO4, 0.05% MgSO4, 0.05% KCl, 0.2% carboxymethylcellulose (CMC) sodium salt, 0.02% peptone, 1.7% agar and 1 L of tap water. CMC Congo red agar consisted of 0.05% K2HPO4, 0.025% MgSO4, 0.188% carboxymethylcellulose (CMC) sodium salt, 0.02% Congo red, 0.2% gelatin, 1.7% agar and 1 L of tap water46.Gram’s iodine consisted of 2.0 g of KI and 1.0 g of iodine dissolved in 300 mL of distilled water. Discs of fungi were cut with a 7.5 mm diameter from the actively growing colony margins of isolates. The discs were then transferred onto CMC and CMC Congo red agar plates and incubated at 28 °C for 4 and 6 days, respectively. After incubation, 5 mL of Gram’s iodine was added to CMC and CMC Congo red agar plates, and the plates were incubated at room temperature in the dark for 5 minutes. All media were autoclaved for 20 minutes at 121 °C.
