Abstract:
Effects of 5 nitrogen sources on the growth of Cordyceps militaris fruit body and the content of cordycepin and Cordyceps polysaccharide were studied. The results showed that the addition of nitrogen sources had a great promotion effect on the whole growth process of Cordyceps militaris, moreover, the addition of peptone and silkworm chrysalis meal was more beneficial to the growth of Cordyceps militaris, and the yield and quality of the fruiting bodies were higher. The content and yield of cordycepin treated with silkworm chrysalis meal were the highest, which reached (7.93+0.092) mg·g
-1 and per bottle(34.06+0.158) mg, and the content of Cordyceps polysaccharide treated by adding peptone was highest, reaching (21.36+0.076) mg·g
-1, and the yield of Cordyceps polysaccharide treated by adding silkworm pupa meal was the highest, reached by per bottle (103.85+0.169) mg.
