Abstract:
A method for preserving pupa infected with Cordyceps spp, entomopathogenic fungi for a long time and a method for regenerating the fungi are provided to dispense with an expensive equipment or high technology for preserving the fungi, and also to produce fruit bodies on consumer demands by taking out the preserved pupa at desired time. The cultivation time of Cordyceps spp, entomopathogenic fungi can be controlled voluntarily, thereby solving the concentration of production time and the surplus or stock of production. A long-term preserving method of pupa infected with Cordyceps spp, entomopathogenic fungi comprises: preparing the pupa infected with Cordyceps spp, entomopathogenic fungi, controlling the water content of the pupa body to 4%, and then preserving the pupa at 4°C or less, or at -70°C after freeze-drying. The fungi regenerating method comprises soaking the preserved pupa in distilled water for 1~3hr, followed by saturating the pupa with water. The infected pupa can be preserved stably in a water content of 4% at a storage temperature of 4°C or less for 135day, and the regeneration ratio is to about 97%. In addition, a preservation period is more increased at lower temperature in freezing, and is up to 1year in preserving at -70°C or less after freeze-drying.
Abstract:
PURPOSE: Provided are an extract of Paecilomyces sp. J300 having antitumor activity and a pharmaceutical composition containing the same. The extract contains novel antitumor matters, and is thus useful for an antitumor drug composition. CONSTITUTION: A extract of Paecilomyces sp. J300 having antitumor activity contains, as antitumor matters, 5,3-dihydroxy-1-N-methyl-indoline-2-carbonylamino-alanyl-hydoxyisoleucinyl-glycine represented by the formula(1) or its derivatives. An antitumor drug composition contains one of 5,3-dihydroxy-1-N-methyl-indoline-2-carbonylamino-alanyl-hydoxyisoleucinyl-glycine or its derivatives including 5 alpha, 6 alpha-epoxy-(22E,24R)-ergosta-8(14), 22-diene-3 beta, 7 alpha-diol of the formula(2), 5 alpha, 6 alpha-epoxy-(22E, 24R)-ergosta-8, 22-diene-3 beta, 7 alpha-diol of the formula(3), ergosta-4, 6, 8(14), 22-tetraene-3-one of the formula(4) and 3 beta, 5 alpha-dihydroxy-6 beta-methoxyergosta-7, 22-diene of the formula(5).

Abstract:
PURPOSE: A method for culturing Isaria sinclairii is provided by inoculating Isaria sinclairii to the pupa or larva of a domestic silkworm, thereby mass producing Isaria sinclairii . CONSTITUTION: The method for culturing Isaria sinclairii using a domestic silkworm comprises the steps of: inoculating spores of Isaria sinclairii to the larva or pupa of a domestic silkworm by spraying the spores on the surface of the larva or the pupa; and forming a fruit body of Isaria sinclairii from the infected pupa, wherein the inoculation process is carried out by diluting the spores of Isaria sinclairii in water in the concentration of 106/ml to 108/ml, spraying the diluted solution on the surfaces of the larvae or pupae of the domestic silkworms aged 2 weeks, 3 weeks, 4 weeks and 5 weeks, and leaving them under 95% of humidity for 12 hours; the larvae or pupae of the domestic silkworms are stored at 20 deg. C or less prior to the inoculation; and the fruit body formation process is carried out under conditions of 15 to 25 deg. C and humidity of 95%.
Abstract:
PURPOSE: Provided is a preparation method of a medium for Entomopathogenic fungi effectively and economically by using silkworm powder used as a hypoglycemic agent. The medium increases the growth rate of Entomopathogenic fungi. CONSTITUTION: The medium for Entomopathogenic fungi is characterized by dissolving 24g of silkworm powder in 1L of distilled water; sterilizing it at 121 deg.C for 15 minutes; filtering the sterilized solution with gauze and a sieve sequentially; adding 15g of agar the pure solution; sterilizing it; and pipetting 21mL of the solution into each petridish the solidifying them.

본 발명은 항암·면역증강 등 각종 효능이 뛰어난 것으로 알려져 있으나 자연에서의 채집이 극히 어려운 관계로 인간에게 유용하게 이용되지 못하고 있는 동충하초(Paecilomyces japonica)를 인공재배하는 방법에 관한 것으로, 동충하초의 일종인 페실로마이세스 자포니카균 포자를 분무기를 이용하여 가잠의 4∼5령기 유충 또는 번데기 표피에 경피 접종한 후, 균사체를 형성한 번데기에서 자실체를 형성시키는 것을 특징으로 한다.
