The Preliminary Investigation on Cultivation Technology of Orange Caterpillar Fungus Cordyceps militaris L. ex Fr. in Viet Nam

Abstract

        Four fruiting media (MT-1, MT-2, MT-3 and MT4) were used to cultivate Cordyceps militaris (orange caterpillar fungus). Results showed that MT-4 had highest biological productivity (11.63 ± 1.34%). Among four basal substrates including three brown rice types A, B, C and paddy rice D were assessed. With biological productivity of 10.92 ± 1.96%, type B brown rice considered as the most suitable substrate to cultivate orange caterpillar fungus. However, fifth subculture started to showy degeneration of fungal stock as evidenced by the change of fruting-body colour, the mycelial density, the number of fruiting-body primordia and biological productivity.
