摘　　要：茁霉多糖(Pullulan)是一种水溶性胞外中性多糖,由真菌出芽短梗霉(Aureobasidium pullulans)发酵生产的。茁霉多糖在食品工业、药品等领域有广泛的应用,是一种很有前景的多糖,但是大规模生产的还很少,主要原因有两个,一个是产量低,另一个是多糖中色素难以除去。综述茁霉多糖的生产菌种、生物合成机理,培养条件的最新研究成果,同时讨论了茁霉多糖的应用前景和研究热点。Pullulan, a neutral water-soluble extracellular polysaccharide, is obtained by fermentation using a fungus, A ureobasidium pullulans. Pullulan was widely used in food industrial, pharmaceutical industrial and other commercial and industrial areas. It was a promising polysaccharide. But mass production is also small, for two main reasons, one is low yield and the other is difficult to remove the polysaccharide pigment. The latest advances on the study of the microbial sources, synthesis mechanism and culture conditions were reviewed. Its industrial applications and current research focus were discussed.
