Characteristics of Cordyceps militaris cultivated on the soybean residue substrate

Abstract

Cordyceps militaris is a medicinal mushroom containing biologically active substances used as medicine in the treatment of many diseases and as a functional food for humans. Study on the growth and development of C. militaris on the medium supplemented soybean residue showed that, with the experimental formula containing: Brown rice 20g/box + soybean residue 20g/box + silkworm pupae 100 g/L + 40 g/L glucose +
5 g/L peptone + 5 g/L yeast extract + 1 g/L KH₂PO₄ + 1 g/L MgSO₄ + 0.2 g/L vitamin B1 (CT4) had the amount of fruiting bodies reached 203.7 ± 9.6 sprouts/box, the fruit body length was 8.8 ±
0.8 cm, the fresh fruit body weight was 28.5 ± 0.8 g/box and the highest biological productivity gained 24.3 ± 1.3%, 2.6% higher than the control formula (CT1). However, the contents of cordycepin and adenosine in CT4 were 3.15 mg/g and 1.75 mg/g, lower than CT1, which were 5.07 mg/g and 2.67 mg/g, respectively.
