    Abstract: This invention provides the process of bioencapsulation for microbial insecticides. The process comprises the steps of followings: mixing proteneous materials such as beans and peanuts into water; making natural gel matrix by heating at higher than 100 deg. C and macerating into homogeneous powder; autoclaving the matrix and cooling at room temperature; mixing cells, spores, and toxin of Bacillus thringiensis with the natural gel matrix; drying or freeze drying the mixture, following by macerating to produce powder, particles, or pellets. This encapsulated materials can be used as microbial insecticides.

    Abstract: PURPOSE: A microorganism, Penicillium griseofulvum, producing pyripyropene A and a method for producing cholesterol metabolism inhibitor are provided, wherein pyripyropene A inhibits the activity of cholesterol acyltransferase(ACAT) which adsorbs cholesterol into blood, and is thus used in decreasing the blood cholesterol concentration. CONSTITUTION: Penicillium griseofulvum F1959 separated from soil by Samson method produces pyripyropene A which inhibits the activity of cholesterol acyltransferase(ACAT) and its inhibition concentration IC50 is about 35 ng/ml which is calculated by the equation. The ACAT inhibitor pyripyropene A is produced by the steps of: incubating Penicillium griseofulvum F1959 in a spawn medium containing 0.5% of glucose, 0.2% of yeast extract, 0.5% of polypeptone, 0.1% of potassium phosphate and 0.05% of magnesium sulfate at 29 deg. C for 18 hours; and incubating the microorganism in a growth medium containing 2% of starch, 0.4% of soytone, 0.3% of pama media, 0.1% of potassium phosphate, 0.05% of magnesium sulfate, 0.3% of calcium carbonate and 0.2% of sodium chloride at 29 deg. C for 120 hours.
