Most fossil fuel-derived polymers used for food packaging are non-biodegradable and induce pollution by microplastic, calling for safer material. Here we review microbial production and applications of pullulan, a unique biopolymer produced by fermentation of agro-residues, using a strain named Aureobasidium pullulan. Chemically modified pullulan is widely used in food, pharmaceuticals, biomedical, and cosmetics. Compared to conventional polymers, pullulan increases the tensile strength 6–37-folds and increases the bioadhesion time 72–120-folds. Pullulan has been recently produced from agro-based waste with yields as high as 58-69 g/L.

大多数用于食品包装的化石燃料衍生聚合物是不可生物降解的，并会引起微塑料污染，因此需要更安全的材料。在这里，我们使用名为Aureobasidium pullulan的菌株回顾了普鲁兰糖的微生物生产和应用，普鲁兰糖是一种通过农业残渣发酵产生的独特生物聚合物。化学改性支链淀粉广泛用于食品、药品、生物医学和化妆品中。与传统聚合物相比，支链淀粉的拉伸强度提高了 6-37 倍，生物粘附时间提高了 72-120 倍。普鲁兰糖最近由农业废弃物生产，产量高达 58-69 g/L。
