Cultural Characteristics ofOphiocordyceps heteropodaCollected from Korea

Abstract

Isolates of Ophiocordyceps heteropoda (Kobayasi) collected from Mt. Halla on Jeju-do, Korea were tested for mycelial growth on different agar media and in the presence of different carbon and nitrogen sources. Similarly, isolates were also incubated at different temperatures as well as under continuous light and dark conditions. Growth was better on Hamada agar, basal medium, and malt-yeast agar, but poor on Czapek-Dox agar. Different carbon sources such as dextrin, saccharose, starch, lactose, maltose, fructose, and dextrose resulted in better growth. Complex organic nitrogen sources such as yeast extract and peptone revealed the most effective growth. Mycelial growth was best at 25℃. The growth rate was faster in the dark than the light, but mycelial density was less compact in the dark.

Mycelial Growth of <i>Paecilomyces hepiali</i> in Various Agar Media and Yield of Fruit Bodies in Rice Based Media

“…The highest colony growth was obtained at pH 7. This was similar to previous studies on other fungal species [16][17][18]. However, pH 7 was not statistically different from pH 6 and 8 (p > 0.05).…”

“…This is same as findings reported on other fungal species namely Cordyceps nutans Pat. [16], Ophiocordyceps longissima [17], Ophiocordyceps heteropoda [18], Cordyceps cardinalis [19] and Cordyceps sinensis (now known as Ophiocordyceps sinensis) [20]. It was interest- A. CHIOZA, S. OHGA Open Access AiM 532 ing to note that even at 5˚C there was some growth at the rate of around 0.89 mm/day in terms of colony diameter.…”

“…Multi-ascospore isolates were derived from fresh O. longissima specimens CRI C-6764, CRI C-7080, and CRI C-8587 following the method of Sung et al [24]. Specimen CRI C-6764 was collected on Mt.…”

“…This temperature is reported as the most favourable for the majority of mushrooms which include Coprinus comatus [15], Paecilomyces hepiali [12], Paecilomyces fumosoroseus [14] [16], Ophiocordyceps heteropoda [17] and Cordyceps cardinalis [18]. The next favourable temperature was 20˚C.…”
