Introduction: Mannan is a major component of the Candida albicans cell wall, composing up to 7% of the cell dry weight, and is one of the main Candida antigens that circulate during infection. It is a serum marker for the presence of Invasive Candidiasis is Candida Mannan antibody, which has been included in the relevant European Organization for Research and Treatment of Cancer/ Mycoses Study ...

BACKGROUND Mannans represent the largest hemicellulosic fraction in softwoods and also serve as carbohydrate stores in various plants. However, the utilization of mannans as sustainable resources has been less advanced in sustainable biofuel development. Based on a yeast cell surface-display technology that enables the immobilization of multiple enzymes on the yeast cell walls, we constructed a...

Antigenicity of pathogenic yeast Candida zeylanoides NBRC 10326 was found to have similar to that of Candida guilliermondii, but it was slightly different, i.e. NBRC 10326 strain cells react strongly with the factor antibodies 1, 4, and 9, and react relatively weakly with factor antibody 5. We have investigated the structural characteristic of cell wall mannan of this strain using a non-degrada...

Wood is one of the important construction materials and it necessary to protect from biological pests. Hemicellulose in wood consist various sugar hexoses or pentoses depending on tree species. This composition can have significant effects interactions with chemical substance as biocides coatings. Interactions glucose, arabinose, mannan, galactomannan, glucogalactomannan, xylan, hemicellulose c...

to evaluatethe effects of supplementing diets of growing japanese quails (n=450; 7 days old) with chromium (cr) yeast and / or mannan oligosaccharides (mos) on productive performance, carcass traits and the immune system are reported. diets were a basal diet (control) or the basal diet supplemented with 600 mg cr-yeast/kg (cr 1), 1200 mg cr-yeast/kg (cr 2), 1.0 g mos/kg, cr 1 + mos or cr 2 + mo...

Background—Crohn’s disease is a familial disorder, and antiglycan antibodies to the cell wall mannan of Saccharomyces cerevisiae (ASCA) are highly correlated with Crohn’s disease. Aims—To determine whether there is a familial pattern for expression of serum levels of anti-mannan Ig, and whether this trait is expressed in clinically unaVected Crohn’s disease family members. Methods—349 patients ...

Around 90% of chronic dermatophyte infections are caused by the fungi Trichophyton mentagrophytes and Trichophyton rubrum. One of the causes of the chronic infection resides in the immunosuppressive effects of the cell-wall components of these organisms. Therefore we have attempted to identify the chemical structure of galactomannan, one of the major cell-wall components. The cell-wall polysacc...

This work pioneers the thermocatalytic conversion of tagua seeds (or ivory nut) from palm Phytelephas aequatorialis into key chemical building blocks, being levoglucosenone, furfural and levomannosan. Annually, ca. 100,000 metric ton those are produced in Ecuador. Mannan (a mannose-polymer similar to cellulose) is main constituent tagua. Thermocatalytic conversions were first explored on analyt...
