on PDA at 26℃. A total of 10 mycelial mats with a 6
mm diameter was inoculated into the medium (100
ml) containing 0.06% KH2PO4, 0.04% K2HPO4, 0.05%
MgSO4・7H2O, 5x10-4% CaCl2, 0.01% yeast extract, 1%
glucose and 0.1% NH4H2PO4 in a 300 ml Erlenmeyer
flask and the flask was placed in a rotary shaker at 30
℃ and 100 rpm for 4 days. The grown mycelium was
homogenized. To a freshly prepared medium (100
ml) containing 0.005% MnSO4 and 0.05% Tween 80
in addition to the medium described above in a 300
ml Erlenmeyer flask, 10 ml of the homogenate was
inoculated. After the fungus was cultivated in a rotary
shaker at 30℃ and 100 rpm for 3 days, the culture filtrate
was recovered by filtering off the hyphae.
