Production of <i>Exopolysaccharide pullulan</i> from inulin by a mixed culture of <i>Aureobasidium pullulans</i> and <i>Kluyveromyces fragilis</i>

Abstract

Pullulan, an extracellular a-glucan produced by the yeastlike fungus Aureobasidiurn pulluluns, is a linear polymer of a-maltotriose units connected by a-(I -+ 6) glucosidic linkages.The fine structure of pullulan has been deter-growth of the two microorganisms for optimum pullulan production was investigated and the possible utilization of Jerusalem artichoke as a carbon source is discussed.mined by Bender and Wallenfelsl-and Catley and Whelan.'With the increase of pullulan applications to food, drug, AND METHODS
