Optimum Conditions for Artificial Fruiting Body Formation of Cordyceps cardinalis

摘要

Stromatal fruiting bodies of Cordyceps cardinalis were successfully produced in cereals. Brown rice, German millet and standard millet produced the longest-length of stromata, followed by Chinese pearl barley, Indian millet, black rice and standard barley. Oatmeal produced the shortest-length of fruiting bodies. Supplementation of pupa and larva to the grains resulted in a slightly enhanced production of fruiting bodies; pupa showing better production than larva. 50 similar to 60 g of brown rice and 10 similar to 20 g of pupa mixed with 50 similar to 60 mL of water in 1,000 mL polypropylene (PP) bottle was found to be optimum for fruiting body production. Liquid inoculation of 15 similar to 20 mL per PP bottle produced best fruiting bodies. The optimal temperature for the formation of fruiting bodies was 25 degrees C, under conditions of continuous light. Few fruiting bodies were produced under the condition of complete darkness, and the fresh weight was considerable low, compared to that of light condition.
