Effect of pH on the Content of Glycolipids inAureobasidium pullulansS–l

Abstract
When Aureobasidium pullulans was cultivated with initial pH 6.0 and pH 2.5 in shaking flasks, only a slight difference was observed in the content of lipids in cells. On the other hand, when cultured with initial pH 2.5 in a jar fermenter, the content of lipids in mycelia was larger than that with initial pH 6.0. The content of sugars in the lipids showed a similar tendency. Glucolipids were easily hydrolyzed with dilute acid into glucose, glucooligo- saccharide and lipids.
