mannan/potato

Cell walls of potato tubers were fractionated by successive extraction with various reagents. A slightly degraded pectic fraction with 77% galacturonic acid was extracted in hot, oxalate-citrate buffer at pH 4. A further, major pectic fraction with 38% galacturonic acid was extracted in cold 0.1 M

In this research, simultaneous contribution of konjac-mannan (0.3%), xanthan (0.3%), and tragacanth (0.3%) gums in tomato ketchup was investigated comparing the physicochemical, rheological, texture, and sensory properties with the control sample containing 0.3% xanthan gum. Samples selected through

Antitumor and antibacterial activity of complex preparations consisting of yeast mannan, diacetile-2,4-dioxohexahidro-1,3,5-triasine, cianohyanidine, alcansulfonic acids (emulsifier E-30), and microbial metabolites was studied. The investigation was carrying out on explants of tuber potato

The genome sequence of the hyperthermophilic bacterium Thermotoga maritima encodes a number of glycosyl hydrolases. Many of these enzymes have been shown in vitro to degrade specific glycosides that presumably serve as carbon and energy sources for the organism. However, because of the broad

In liquid culture conditions, the yeast-like fungus Tremella mesenterica occurs in the yeast state and synthesizes an exopolysaccharide (EPS) capsule, which is eventually released into the culture fluid. It is composed of an alpha-1,3-D-mannan backbone, to which beta-1,2 side chains are attached,

Phellinus pini exopolysaccharide (PPE) is a mannan produced by P. pini when cultured in potato dextroseagar medium. Partial hydrolysis with acid, periodate oxidation and Smith degradation, methylation and 13C nuclear magnetic resonance (NMR) spectroscopy were used to elaborate its structure. Results

Carbohydrate Binding Modules (CBMs) targeting cellulose, xylan and mannan have been reported, however, a CBM targeting rhamnogalacturonan I (RG I) has never been identified. We had studied earlier a rhamnogalacturonan lyase (CtRGL) from Clostridium thermocellum that was associated with a family 35

The ergosterol biosynthesis inhibitor prochloraz is a broad-spectrum fungicide and has been registered in China since 2007 for control of the economically important necrotrophic pathogen Sclerotinia sclerotiorum. In this study, relative baseline sensitivity and toxic actions of prochloraz on S.

Three unique classes of carbohydrates were isolated from the hyphal cell walls of Phytophthora megasperma f.sp. glycinea (Pmg) and compared with other substances for their activity as elicitors of the phytoalexin glyceollin in soybean tissues. Glucomannans extracted from cell walls with soybean

The deep-sea fungus Penicillium griseofulvum produces an extracellular polysaccharide, Ps1-1, when grown in potato dextrose-agar medium. Ps1-1 was isolated from the fermented broth using ethanol precipitation, anion-exchange and size-exclusion chromatography. Ps1-1 is a galactomannan with a
