STUDY ON MEDIUM OF SUBMERGED CULTURE FOR GRIFOLA FRONDOSA
灰树花深层发酵培养基的研究

Grifola frondosa lakes advantage of rich sources of carbon and nitrogen. The optinum carbon source and nitrogen source are potato juice with glucose and wheat bran respectively. When there was a growth promoter-juice of Chinese chestnut shell in the medium, the mycelian growth rate reach 140%. The kinds of itrogen and growth promoter influenced mycelian growth obviously, and there were obvious effects with each other, too. The concentration of carbon source was too high in the medium was unfavorable to growth. In addition, the better submerged culture medium of Grifola frondosa was QF: glucose 60g, KH_2PO_4lg, MgSO_4 0.59, CaCl_2 0.1g, juice of Chinese chestnut shell 150g, water lL.
