Aureobasidium pullulans polysaccharide

Pullulan is a glucan of (1 6)-a-D-linked maltotriose residues produced by Aureobasidium pullulans from starch or sucrose feedstockJ It is well soluble in aqueous medium and forms films that possess thermal stability and are antistatic and elastic. Pullulan has adhesive properties and is directly compressible under heat with moisture. The polysaccharide is produced on an industrial scale and is used for multiple applications, including food, pharmaceuticals, and cosmetics. It has recently been classified as GRAS by the U.S. FDA. [Pg.2365]

Pullulan is the extracellular polysaccharide produced by Aureobasidium pullulans. The polysaccharide is composed of malto-tetraose units linked together through the 1 and 6 positions on adjacent triose or tetraose units. [Pg.253]

Extracellular polysaccharide puUulan is produced by the fungus Aureobasidium pullulans (syn. Pullulariapullulans). The molecule consists of D-glucopyranose units linked alternately by two a-(l->-4) and one a-(1 6) bonds (4-185). The molecular weight varies widely, from 1.5 to about 800 kDa, according to origin of the fungus and cultivation conditions. [Pg.287]

Glycerol is another substrate of importance in the biomass conversion, and it can be transformed to the added-value dihydroxyacetone with a supported palladium catalyst. " A related approach is the added-value modification of nature-derived materials. For instance, pullulan, a polysaccharide extracted from the fermentation medium of the Aureobasidium pullulms bacteria, can be functionafized by the introduction of various groups, such as carboxylic ones, what significantly influences its hydrophificity, etc. ... [Pg.107]
