Cultivation of Eri-Silkworm Cordyceps militaris and Determination of its Amino Acid Composition

Abstract:

In order to study eri-silkworm Cordyceps militaris culture condition and the amino acid composition features in different parts of it, this experiment optimized eri-silkworm Cordyceps militaris artificial culture conditions, and determined the amino acid composition in different parts. The results showed that the inoculated eri-silkworm Cordyceps militaris which was kept at low temperature (18 ° C) and seventeen dark days grew well and began to use natural light in the eighteenth day with humidity 85%, temperature 21 ° C, which could induce the germination of the sporophore. The artificial cultivation period was about 40 days. Amino acid test shows that its sporophore and stroma are rich in 17 kinds of amino acids, including 7 kinds of essential amino acids. The higher levels of amino acids in its sporophore are lysine 15.28%, glutamate 15.05% and aspartate 7.55%. The higher levels of the amino acids in the stroma are glycine 16.11%, lysine 9.16% and glutamate 8.30%. The results indicate that eri-silkworm Cordyceps militaris can be artificially cultured. As there are differences of amino acid composition in different parts of eri-silkworm Cordyceps militaris, this study lays the foundation for its large-scale cultivation and the exploitation of its amino acid nutrition.
