Abstract
The liquid culture condition was examined on C. sinensis of the Cordyceps genus. As the result, initial pH was widely spread between 3.5〜8.0, and growth was proven. The growth increment reached a maximum in the inside of pH 5.0 There were 8 kinds of organic nitrogen on the nitrogen source. The growth was better than the growth when inorganic nitrogen was added, the yeast extract was most suitable, and the maximum for the concentration was 4 %. As a result of examining 7 types of alditol, polysaccharide, disaccharide, monosaccharide as a carbon source, glycerol and mannitol were the most suitable. This sugar was also alditol on anyway. Then, the growth in glycerol, erythritol, sorbitol and the medium, which was added to the mannitol, was good because it cultivated C. sinensis by increasing the type of alditol in 5 types. In addition, it was proven that it was the glycerol of the alditol as a carbon source which was most suitable and that the concentration was 3 % as a result of 4 kinds of concentration of this alditol which changed at 0〜6 % and cultivated it.
