Abstract

In this study, we isolated microorganisms from dried persimmon in Sangju and obtained 15 strains of microorganisms as the basic research to prevent the quality changes during drying and storage of dried persimmon. Contaminated microorganisms were separated using seven species of medium. Viable cell counts of dried persimmon from Sangju was $5.18{\times}10^2{\sim}1.68{\times}10^7$ CFU/g. Green mold K2-1 accounted for the highest percentage in the contaminated dried persimmons and identified as a major causative microorganism. Light violet and creamy yeasts were the second largest contaminated microorganisms. Green mold K2-1 strain was identified as Penicillium sp. and fungus K-1 and K-3 were identified as Caldosporium sp. and Aspergillus sp.
