Abstract
A good mycelial growth of F. fraxinea was observed on CDA medium. The optimum temperature and pH for the mycelial growth of F. fraxinea was at $30^{\circ}C$ and pH 6.0, respectively. Glucose was found to be the best carbon source and arginine was favored as nitrogen source. When the basal medium was supplemented with organic acids, the best growth was shown in succinic acid and the poor growth was shown in oxalic acid. Thiamine.HCl showed the best results on the growth of this fungus on basal medium. Mycelial growth of F. fraxinea was quite good when oak tree sawdust was used to cultural substrates. The best mycelial growth was observed when 20% of rice bran was added as a supplement on sawdust substrates. Higher yield of F. fraxinea was observed on the medium with oak tree and acacia sawdust.
