Abstract
|
|
|
NIAST has developed the artificial cultivation technique of entomopathogenic fungus, Isaria sinclairi by using the silkworm.
NIAST is planning to provide the silkworm farmers the guidance of the technique.
Screening of pharmacologically active principles of
I. sinclairii is needed to register the fungal breeding, attain the approval of food materials, and ultimately
position the fungus as a high value-added product. The result of investigating the characteristics of Isaria sinclairi was
showed that conidia were irregularly long oval-shaped and measured 633x333 μm in average. The optimal condition
of cultivating hyphae was pH 5.0 in acidity and 21-25°C in temperature. And the best condition of producing conidia
was pH 6.0 in acidity and 16-20°C in temperature.
