    Abstract: Penicillium janthinellum D4株篩選自越南Tay Nguyen大學之幾丁聚醣酶生

    產菌。本研究探討P. janthinellum D4發酵烏賊軟骨生產幾丁聚醣酶之較適條


    Macro-prep DEAE Cartridge等步驟,純化出兩種幾丁聚醣酶F1及F2。幾丁聚


    pH、熱安定性以及pH安定性分別為60℃、pH 7~9、25~40℃以及pH 10。於

    The chitosanase producing strain Penicillium janthinellum D4, was

    isolated from soil in Tay Nguyen University in Vietnam. Two

    chitosanases F1 F2 were purified from the culture supernatant by

    ammonium sulfate precipitation, DEAE-Sepharose column

    chromatography and Macro-prep DEAE Cartridge. The molecular mass

    of CHS was estimated to be 49kDa by SDS-PAGE. The optimum

    temperature, optimum pH, thermal stability, and pH stability of CHS F2

    were 60℃, pH 7~9, 25~40℃, and pH 10, respectively. The activity of CHS F2 was

    inhibited by Fe2+,Cu2+,and Mn2+.
