The purpose of this study was to enhance the immune-enhancing activity mushroom strains through fermentation promote food use leaf extracts S. quelpaertensis containing β-glucan. We evaluated immunomodulatory effect from fermented leaves (SQGL, SQHE, SQPL). products were prepared by using mycelia (Ganoderma lucidum, Hericium erinaceum, Phellinus linteus). content β-glucan, a major substance in ...

Glycans are major nutrients available to the human gut microbiota. The Bacteroides are generalist glycan degraders, and this function is mediated largely by polysaccharide utilization loci (PULs). The genomes of several Bacteroides species contain a PUL, PUL1,6-β-glucan, that was predicted to target mixed linked plant 1,3;1,4-β-glucans. To test this hypothesis we characterized the proteins enco...

A Potential Explanation of a Positive Serum β-Glucan Assay in Mucormycosis To the Editor—I read with interest the nice study by Angebault et al [1] that gives a " real world " picture of the subop-timal performance of the serum β-glucan assay. Unexpectedly, the authors found that serum β-glucan test was positive in 3 of the 6 cases of mucormycosis in their series with no apparent cause of false...

1. Commercial pressed baker's yeast, and cell walls prepared from it, were extracted in various ways and the products examined by a number of techniques, including infrared spectroscopy and electron microscopy. 2. The glucan components of the walls cannot be extracted from intact yeast cells by 3% (w/v) sodium hydroxide at 750, but at least one-third ofthe glucan of cell wall preparations is di...

Associations between house dust-associated beta-(1,3)-glucan exposure and airway inflammatory reactions have been reported, while such exposures in early childhood have been suggested to protect against asthma and wheezing. Most epidemiological studies have used reservoir dust samples and an inhibition enzyme immunoassay (EIA) for beta-(1,3)-glucan exposure assessment. The objective of this stu...

Salmonella enterica serovar Enteritidis is the major zoonotic and intracellular pathogen. Different strategies have been developed to prevent the S. Enteritidis infection. The beta-1,3-1,6-glucan of Schizophyllum commune was used as an immunological booster to determine the minimal dietary level of beta-glucan that would restrict S. Enteritidis infection through the effects of beta-glucan on th...

Shiitake mushrooms (Lentinula edodes) containing β-glucans may be beneficial for human health; they have been used in the treatment of cancer, hypertension, and high cholesterol levels. The objective of this study was to determine the β-glucan content in different sections of the fruiting bodies and mycelia of ten shiitake mushroom cultivars. The measured β-glucan content ranged from 20.06 ± 1....

Glucans, despite decades of intensive research, has been used only recently in the evaluation of intestinal biology and diseases. This review is focused on comprehensive summary of the current knowledge of transport and absorption through the gastrointestinal tract, therapy of ulcerative colitis by glucan and effects of glucan on gastrointestinal track-related tumors. Studies demonstrating the ...

The yeastlike form of Paracoccidioides brasiliensis strain IVIC Pb9 reduced the amount of alpha-1,3-glucan in its cell wall from 45 to 3% when subcultured in vitro for several years. This strain regained its alpha-1,3-glucan up to 25% of the total cell wall when grown in vivo. A mutant strain of P. brasiliensis Pb9, named IVIC Pb140, reported to have 1,3-mannan instead of alpha-glucan in the ce...

BACKGROUND Mould exposure has been linked to childhood asthma and bronchial hyper-responsiveness. Few studies have assessed beta-(1,3)-d-glucan (beta-glucan), a significant fungal cell wall constituent, in relation to asthma in adolescence. OBJECTIVE To determine whether house dust-derived beta-glucan exposure at age 7-10 is associated with the development and persistence of atopic and non-at...
