  1. Standard error are given in parentheses. n = 5 replicates
  2. Within columns, values bearing different subscript letters were significantly different from each other (p < 0.05)
  3. Concentration values for mycelium components are expressed in μg/g of mycelial dry weight
  4. Mycelium growth is given in grams of mycelial dry weight/1 L of culture medium
