【Abstract】 Pullulan is an extracellular polysaccharide produced by Aureobasidium pullulans, which is widely used in food, medicine, cosmetics and other fields. However, the specific biosynthetic pathway and molecular weight regulation mechanism of pullulan are still unclear. Recent research on those topics are reviewed, and a proposal biosynthetic pathway of pullulan is concluded. And the factors that in?uence yield and molecular weight of pullulan are also summarized in this paper.更多还原
