Pullulan, one of the commercially important microbial exopolysaccharides, is produced by the yeast like fungus Aureobasidium pullulans. It is non-mutagenic, non-toxic, non-hygroscopic, tasteless, odorless, water soluble and edible polymer. Owing to its excellent film forming properties, and typical rheological properties, it is extensively used in diverse industrial applications that include food, agriculture, textiles, cosmetics and pharmaceuticals. In the recent past, there has been growing interest to produce pullulan from low cost substrates in order to bring down cost of pullulan. The cost, productivity and properties of pullulan are highly influenced by the selection of raw material (upstream processing), type of fermentation & fermentation conditions (bioprocessing) and product recovery steps (downstream processing). In addition, both upstream and bioprocessing also affect the rheological, thermal and physical properties of the product. The present review discusses the literature on upstream processing, bioprocessing, product recovery and applications of pullulan.
出芽短梗霉多糖是一种具有商业价值的微生物胞外多糖，由酵母样真菌出芽短梗霉产生。它是一种非诱变、非毒性、非吸湿性、无味、无嗅、水溶性和可食用的聚合物。由于其优良的成膜性能和典型的流变性能，它被广泛应用于食品、农业、纺织、化妆品和制药等多种工业应用中。在最近一段时间里，人们越来越有兴趣从低成本的基质中生产出芽短梗霉多糖，以降低出芽短梗霉多糖的成本。出芽短梗霉多糖的成本、生产力和性能受到原材料选择（上游加工）、发酵类型和发酵条件（生物加工）以及产品回收步骤（下游加工）的影响。此外，上游和生物加工也会影响产品的流变性、热学和物理性能。本综述讨论了关于出芽短梗霉多糖的上游加工、生物加工、产品回收和应用的文献。
