Abstract：Using the moldy dried persimmon of Small Calyx as experimental materials,the main mold strains were isolated and identified by morphological and molecular biological methods,and their biological characteristics were also studied.Two dominant strains,named S1 and S2 were isolated and identified as Penicillium chrysogenum and Aspergillus niger respectively by morphological and molecular biological methods.The optimal growth conditions for S1 strain were temperature as 25℃,humidity as more than 70％,pH value as 5.0 ～ 7.0,thermal death point and time as 65℃ and 5 minutes or 70℃ and 1 minute.The optimal growth conditions for S2 strain were temperature as 30℃,humidity as more than 70％,pH value as 5.0,thermal death point and time as 65℃ and 15 minutes or 70℃ and 1 minutes.
