Production of α­ Amylase by a local Isolate of the Fungus Aureobasidium pullulans

A local isolate of the fungus Aureobasidium pullulans was obtained from house ceilings in Mosul city . The isolate was identified as A. pullulans on the basis of appearance of polymorphism in the colonies , melanin pigment and pullulan production in flask cultures. - Amylase production by the local isolate was compared with a standard isolate of the fungus A. pullulans ATCC 42023 . Production of - Amylase by the local isolate slightly exceeded that produced by the standard isolate . Production of - Amylase by the local and standard isolate was 4.4 and 4.08 unit / ml respectively after four days incubation .
