The Liquid Cultivation of the Mycelia of Pyrofomes demidoffii

SU Jue; HE Xin-sheng; ZHENG Lin-yong

Pyrofomes demidoffii is a new recorded species of the new recorded genus in the China and Asia, and a pathogenic fungus of juniper. Adopting the liquid fermentation to study its biological characteristics such as vegetal nutrition condtion of mycelia, the results indicated that the mycelia of P. demidoffii could be produced by liquid fermentation process. Starch and bran were the optimum carbon and nitrogen source, and P, K, Mg had the effection of acceleration to the growth of mycelia, Fe, Zn inhibited its growth. The growth curve of the logistic equation was deduced: y=0.22/(1+1.019e-0.013x), the weight of the dry mycelia was 0.22 g·100 mL-1.
