Polysaccharides Produced by Fungi

3-Glc chains Pachyman Poria cocos 0.1-2.0x10 Water insoluble [78,79] 

3-Glc backbone with (i- 1,6-Glc side chains Lentinan Lentinus edodes 0.23-0.50 0.3-8.0x10 Water soluble [61-63] 

4-Glc backbone with ( -l,3 / ( -l,6-Glc side chains Krestin Trametes versicolor 0.25 1.0x10= Water soluble [74,98-100]  

The [Gj] structure (where represents the a-l,4-linked trimer maltotriose and n the number of maltotriose units), together with the presence of hydroxyl groups along the chain, confer pullulan its unique physicochemical properties very good solubility in water and high structural flexibility. Pullulan capacity to form thin layers, electros-pxm nanofibers, nanoparticles, flexible coatings or stand-alone films [115] makes it very attractive for various pharmaceutical and medicinal applications.
