Effect of Precursor and Fungal Elicitor on Cordycepin Production

Abstract

Abstract: Effects of adenosine and Phytophthora sp. (YL) on the cordycepin production and biomass of Cordyceps millitaris 97-0706 were studied. The ruselts showed that 3.6 mg/ml adenosine added into shake flask culture before fermentation, after 7 d the content of cordycepin reaches to 8.55±0.09 mg/g (p<0.01), 2.2 times more than that of control; 2.0 mg/ml adnosine and 80μg/ml YL together added into shake flask at starting , the cordycepin production of 0706 reaches to 8.25±0.08 mg/g, which is no significant difference (p>0.05) to cordycepin production with only 2.0 mg/ml adenosine added (8.21±0.074 mg/g). But adenosine and YL could cooperate to enhance the mycelia biomass of 0706 (46.11±0.10 g/L), 1.9 times of that of control.
