Four fruiting media(MT-1, MT-2, MT-3 and MT4) were used to cultivate Cordycepsmilitaris(orange caterpillar fungus). Results showed that MT-4 had highest biological productivity(11.63± 1.34%).Among four basal substrates including three brown rice typesA, B, C and paddy riceD were assessed. With biological productivity of 10.92± 1.96%, type B brown rice considered asthe most suitable substrateto cultivate orange caterpillar fungus. However, fifth subculturestarted to showy degenerationof fungal stock as evidenced by the change offruting-body colour, the mycelial density,the number of fruiting-body primordia andbiological productivity.
