Abstract:
... The glucans of basidiomycetes are an important class of polysaccharides with potential biological activities. In this work, the β-glucans were isolated from the fruiting bodies of edible mushrooms, Pleurotus eryngii and Pleurotus ostreatoroseus, via extraction with hot water, and then fractionation by freeze-thawing. The insoluble glucans gave similar 13C NMR spectra, monosaccharide composition an ...

Abstract:
... The polysaccharide (VTh) extracted with water from the gum exudate of the trunk Vochysia thyrsoidea gave a solution of high viscosity and was homogeneous, with Mw 92.5 x 10³ and dn/dc = 0.212. Partial hydrolysis gave a main chain of to 4)-β-d-GlcpA-(1 to 2)-α-d-Manp-(1 to repeating groups. Since VTh contained 24% GlcA, neither its monosaccharide ratio (GC-MS of alditol acetates) nor methylation re ...

Abstract:
... As polysaccharides of the mushroom genus Pleurotus can act as biological response modifiers, we now describe the chemical characterization of a new water-soluble αβ-glucan from the fruiting bodies of the edible mushroom Pleurotus florida. It was obtained via successive aq. extraction, freeze-thawing, precipitation with Fehling solution, and dialysis through a membrane with M(r) 1000 kDa cut-off. I ...

Abstract:
... An unusual water-soluble glucan was isolated from the fruiting bodies of Ganoderma resinaceum following alkaline extraction. Its structure was determined using NMR spectroscopy (13C, 1H, and 1H (obs.), 13C HMQC), methylation analysis, and controlled Smith degradation. It was a highly branched β-d-glucan containing a (1 to 3)-linked β-d-glucopyranosyl main chain, partially substituted at O-6, princ ...

Abstract:
... The peach tree (Prunus persica) produces gum exudates on its trunk and fruit. The former was extracted with water to give polysaccharide (PPN) and residual material was extracted with alkali giving structurally similar PPNA (NMR examination), which was formed in a slightly higher yield (42% compared with 37%). PPNA consisted of Ara, Xyl, Man, Gal, and uronic acids in a 36:7:2:42:13 molar ratio and ...

Abstract:
... For many years mushrooms have been consumed and appreciated by their nutritional value, and medicinal properties. The traditional mushroom cultivation takes too long and the macrofungi biotechnology has not been explored in its full potential yet. The goal of this work was to observe if different carbon sources could improve the yield and diversify fungi nutrient composition in submerged culture. ...

Abstract:
... The polysaccharide (VTP) from the gum exudate of Vochysia tucanorum gave aqueous solutions of low viscosity. VTP contained two components, which on freeze-thawing, gave rise to soluble (S-VTP) and precipitated (P-VTP) fractions, with Mw 350,000 and 520,000 g/mol, and dn/dc 0.134 and 0.139, respectively. Acid hydrolysis of S-VTP provided Ara, Xyl, Man, Gal, Glc in a 43:1:5:18:2 molar ratio (GC-MS) ...
