The polysaccharides can be obtained from the fruit body, mycelium, culture broth and spores of mushroom. In this study, oyster mushroom (Pleurotus flabellatus) culture was produced by submerged culture fermentation due to its higher productivity and faster fermentation rate. Methods The biomass obtained from submerged culture fermentation was extracted by using hot water extraction. The polysaccharides were tested using β-glucan kit and also studied using small angle X-ray scattering (SAXS) equipment. Then the polysaccharides were separated using column chromatography before determining the molecular weight using gel permeation chromatography-multi angle laser light scattering (GPC-MALLS). Results Both endopolysaccharide and exopolysaccharide obtained have shown the presence of β-glucan (1,3;1,6). The polysaccharides also showed the presence of high molecular weight (~3×10^6 Da) and low molecular weight components. SAXS results showed that the maximum agglomerate size was ~27 nm and the average size of globular was 2.6 nm. Conclusion The presence of high molecular weight β-glucan showed potential application as immunomodulatory agents. The polysaccharides can be classified as nanobiomaterials. These studies supported potential usage of local compounds in medical applications.
