Varietal characteristics of cross-bred Cordyceps militaris 'Dowonhongcho'

Abstract

Cordyceps militaris is being studied and cultivated as a medicinal mushroom having many valuable biological and pharmaceutical activities. In the breeding of new C. militaris mushroom, single ascospores were isolated and examined their mycelial growth, mycelial density, and production of stroma and perithecia. Among them selected isolates were crossed and hybrids were produced showing high quality fruiting bodies on artificial media. Mycelial growth rate of new strain 'Dowonhongcho' was higher than that of better on 'Yedang 3' on SDAY at 10-25 o C. The stromata of new strain were clubshaped and bright orange-red. Its height was 6.1 cm and the cordycepin content was 0.34% on average. The new strain showed 9% higher yield than 'Yedang 3' with producing firmer fruit bodies. The optimum temperature for mycelial growth was 22~25 o C and the optimum temperature for stroma development was 18~22 o C. Fruiting bodies were began to produce 45 days later after inoculation. This new cultivar may serve as a valuable one for artificial cultivation and industrial-scale production of C. militaris.

Thermophysical properties of Cordyceps militaris change during the freezing process

“…The ash and fat content are insignificant, accounting for 1.43% and 1.41%, respectively. This result is slightly different from the composition of the sample of Cordyceps reported by Byung-joo Lee et al [20] with the corresponding components of moisture 86.26%, protein 5.03%, lipid 0.12%, carbohydrate 7.77% and ash 0.82%. The difference in the composition of substances in these samples of CM may be due to differences in origin, conditions, and cultivation methods.…”

Cultural characteristics and cordycepin production of some Cordyceps militaris strains under artificial cultivation conditions

“…All five strains investigated in this study showed the ability to form and develop primordia to the maturity stage. According to Lee et al (2015), the fruiting bodies of strain Dowonhongcho and strain Yedang 3 were formed on 15 days after inoculation. Under favorable conditions, the period for substrate colonization, primordia formation, and harvest of C. militaris were 5-6 days, 12 days, and 45-50 days after inoculation, respectively (Du et al, 2010).…”

Developing and solving the mathematical model of transient heat and mass transfer in the freeze-drying of Cordyceps militaris

“…Cordyceps militaris (CM) is a species of fungus in the family Cordycipitaceae and the type species of the genus Cordyceps [1]. Its fruitbody is orange, (5÷8) cm long, D = (3÷5) mm in diameter The main components in the fruit body contain protein, moisture, ash, fat, and carbohydrates with different ratios depending on the type of CM [2][3][4]. CM is used as a functional food to prevent and treat some fatal diseases because it contains many vitamins and amino acids such as adenosine, cordycepin, and many other rare active ingredients [1,5].…”
