Abstract:
In order to improve the metabolism yield of cordycepin and adenosine,we studied nitrogen sources ,the levels of nitrogen sources and carbon sources,dynamic development in liquid culture ,as well as the total yield of cordycepin and adenosine in culture system through determining the contents of cordycepin and adenosine by HPLC .The results are as follows: not only animal protein but also some plant protein is very good nitrogen sources; in culture solution the suitable levels of nitrogen sources and carbon sources is respectively 3% and 4%; the content of adenosine in culture solution is very low, while it is quite high in mycelia; it is much higher that the total yield of cordycepin in culture solution than in mycelia; when the culture system is oscillated and cultured after 7~9 days, the total yield of cordycepin and adenosine are both high.
