Abstract

A fungal strain was isolated as a pullulan-producer from plant leaves and identified as Aureobasidium pullulan GM21. With A. pullulans GM21, culture conditions were optimized for the pullulan production and the changes of the molecular weight of pullulan produced were investigated according to the culture conditions we obtained maximum conversion yield of pullulan about 58-60%(40.8-42.0g/l) from 7% sucrose at 25C, initial pH 7.5 by the batch cultivations either in Erlenmeyer flask or in jar fermentor.
