This study was conducted to increase the bioactivity of litchi pericarp polysaccharides (LPPs) biotransformed by Aspergillus awamori. Compared to the non-A. awamori-fermented LPP, the growth effects of A. awamori-fermented LPP on Lactobacillus bulgaricus and Streptococcus thermophilus were four and two times higher after 3 days of fermentation, respectively. Increased 1,1-diphenyl-2-picrylhydra...

The present study showed that oral mushroom beta-glucan treatment significantly increased IFN-γ mRNA expression but significantly reduced COX-2 mRNA expression within the lung. For LLC tumor model, oral Ganoderma lucidum or Antrodia camphorata polysaccharides treatments significantly reduced TGF-β production in serum. In addition, IL-12 and IFN-γ mRNA expression were significantly increased, bu...

Polysaccharides are structurally complex and essential constituents of life, and therefore, studies directed to these kinds of molecules have received scientific attention. Despite an easy availability of Dolichos biflorus Linn and Trachyspermum ammi (Linn) seeds isolation, characterization and antimicrobial studies of polysaccharides derived from these two natural sources have not been investi...

objective(s):cyclophosphamide (cp) toxicity on testis was hampered by squid ink polysaccharide (sip) via restoration of antioxidant ability in our previous investigations. this study investigated roles of nrf2/are signal pathway in testis of treated mice. materials and methods: male kunming mice were employed to undergo treatment with sip and/or cp. protein levels of nrf2, keap-1, histone deace...

marshmallow is a medicinal plant containing mucilage polysaccharides and various phenolic acids. boron (b) is an essential micronutrient whose necessity for plant growth and development has been attributed to its role in cell wall pectin network and maintenance of integrity and performance of membranes. the present study was aimed to investigate the effects of different concentrations of b (0.0...

A novel and industrially applicable strategy for separating and purifying the water-soluble polysaccharides from the fresh Spirulina platensis is introduced in this study. After hot water extraction, using chitosan flocculation treatment, 86.0% of the particles and 85.9% of the pigments in the crude extract were removed. The purity of polysaccharides could be increased to 94.6% and 96.1% by app...

β-(1→3)-Glucans can be found as structural polysaccharides in cereals, in algae or as exo-polysaccharides secreted on the surfaces of mushrooms or fungi. Research has now established that β-(1→3)-glucans can trigger different immune responses and act as efficient immunostimulating agents. They constitute prevalent sources of carbons for microorganisms after subsequent recognition by digesting e...

Sulfated polysaccharides and their lower molecular weight oligosaccharide derivatives from marine macroalgae have been shown to possess a variety of biological activities. The present paper will review the recent progress in research on the structural chemistry and the bioactivities of these marine algal biomaterials. In particular, it will provide an update on the structural chemistry of the m...

Polysaccharides synthesized by microorganisms (bacterial cellulose, dextran, pullulan, xanthan, etc.) have a set of valuable properties, such as being antioxidants, detoxifying, structuring, biodegradable, etc., which makes them suitable for variety applications. Biocatalysts are the key substances used in producing polysaccharides; therefore, modern research is focused on composition and prope...

Bioactive polymers mainly polysaccharides such as cellulose, chitin, amylose and beta-glucan are well discovered from various sources in nature. Amongst chitin, as the second most abundant polysaccharides after cellulose, is known as a highly insoluble polysaccharide consisting of β-4-linked N-acetyl-D-glucosamine, which has been identified as a structural component of crustaceans, crabs, shrim...
