Abstract
Mycelial growth and fruit body formation of Paecilomyces nipponica on various media were investigated. Basal medium contained 40g of polished rice grain (40g), corn steep liquor (0.2%), KH_2PO_4 (0.2%) and MgSO_4・7H_2O (0.05%). Among various test media, the substitution of 5g of rice grain with pupa powder, wheat bran, millet or corn powder from the basal medium was good for fruit body cultivation, but the addition soybean residue tended to restrict for growth. The substitution of 10g of polished rice with egg yolk at 10g wet base from the basal medium was the most suitable for fruit body cultivation. Addition of yeast extract or polypepton into the basal medium also promoted both the mycelial growth and fruit body formation of the test fungus.
