Isolation and Characterization of Pollulan Produced by a Local Isolate of Aureobasidium Pullulans
MetadataShow full item record
A local isolate of Aureobasidium pullulans was obtained from fig leaves surface. The isolate was identified as A. pullulans on the basis of appearance of polymorphism in the colonies, melanin pigment and pullulan production in shake flask cultures. Pullulan production by the local isolate of A pullulans was two thirds of that produced by ATCC 42023. The studies of physico — chemical properties, chemical analysis, sugar composition periodate oxidation and smith degradation showed that the pullulan produced by the local isolate is nearly similar to the pullulan produced by other strains of A. pullulans.
