摘要：

Aureobasidium pullulans - when grown in fed-batch fermentation on 190 g glucosel/l produced 68 g exopolysaccharide/l with a productivity of 0.42 g/l . h. When the impeller speed was increased from 280 rpm to 340 rpm, the exopolysaccharide increased to 101 g/l, the productivity was 0.90 g/l h and the conversion ratio was 63% (w/w).
