About Pullulan
Pullulan is an extracellular water-soluble polysaccharide similar to glucan and xanthan gum produced by fermentation of Aureobasidium pullulans, which was found as a special microbial polysaccharide in 1938 by R.Bauer.
Pullulan can be used in the pharmaceutical industry to manufacture capsules, lozenges, amorphous drugs, hemostatic agents, plasma extenders, X-ray fluoroscopy, toxoids and vaccine protectants; wound sutures; artificial organs and anticoagulant medical materials, etc.. Compared with other capsules, Pullulan capsule has highly obvious advantages.
Pullulan is used for the development of copolymers, permeability barrier coatings, nanofibers, nanospheres, nanogels, and biofilms with potential uses that range from protective food wrapping materials to biocompatible tissue engineering and drug delivery materials and structures.
