Pullulan is a microbial exo-polymer produced by yeast like fungus Aureobasidium pullulans, with distinctive physico-chemical properties that make it a potent candidate for biomedical applications.
Pullulan is an imperative microbial exo-polymer commercially produced by yeast like fungus Aureobasidium pullulans Its structure contains maltosyl repeating units which comprises two alpha-(1 -> 4) linked glucopyranose rings attached to one glucopyranose ring through alpha-(1 -> 6) glycosidic bond. The co-existence of alpha-(1 -> 6) and alpha-(1 -> 4) glycosidic linkages endows distinctive physico-chemical properties to pullulan. It is highly biocompatible, non-toxic and non-carcinogenic in nature. It is extremely resistant to any mutagenicity or immunogenicity. The unique properties of pullulan make it a potent candidate for biomedical applications viz. drug delivery, gene delivery, tissue engineering, molecular chaperon, plasma expander, vaccination. etc. This review highlights the potential of pullulan in biomedical research and development.
