In this paper, a polysaccharide fraction (FMPS) was purified from the floral mushroom cultivated in Huangshan Mountain for the first time. Physicochemical properties and antioxidant activities of FMPS were investigated. FMPS had an average molecular weight of 7.2×10(5)Da and was composed of glucose. On the basis of FT-IR, NMR and methylation analysis, the(More)
In recent decades, microbial synthesis of polysaccharides with special functional properties has attracted increasing attention. This work reported a novel exopolysaccharide (EPS)-producing strain, Klebsiella sp. PHRC1.001 isolated from activated sludge. Physicochemical, rheological, emulsifying and toxicological properties of the obtained EPS were(More)
Polysaccharides from Dendrobium huoshanense possess immunostimulating activity, antioxidant activity and anticataract activity. In order to produce the active polysaccharides from Dendrobium huoshanense through cell culture, we investigated the effects of salicylic acid on cell growth, accumulation of polysaccharides and utilization of carbon source in(More)
