Sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of them medicinal plant. In this study the extract obtained from basal stalk rot of Helianthus annuus L., attacked by S. sclerotiorum, was subjected to the analysis of FTIR to identify the presence of beta-glucan. FT-IR spectrum showed four ranges of bands in 890 cm-1, two overlap band in 1047 and 1078 ...

In vitro fermentabilities of the oat flour digestion residues (ODR) from two commercial oat lines with 4.7 and 5.3% β-glucan and from two high-β-glucan experimental lines with 7.6 and 8.1% β-glucan were evaluated and compared with fermentations of lactulose, purified oat β-glucan (POBG), and purified oat starch (POS). Substrates were fermented by using an in vitro batch fermentation system unde...

High intake of dietary fiber is claimed to protect against development of colorectal cancer. Barley is a rich source of dietary fiber, and possible immunomodulatory effects of barley polysaccharides might explain a potential protective effect. Dietary fiber was isolated by extraction and enzyme treatment. A mixed-linked -glucan (WSM-TPX, 96.5% -glucan, Mw 886 kDa), an arabinoxylan (WUM-BS-LA, 9...

β-(1,3)-D-Glucan with β-(1,6) branches has been reported to have various pharmacological activities, such as anti-tumour and anti-infection activities, which result from its immunomodulating effects. Gastric lesions result from an imbalance between aggressive and defensive factors. In the present study, we examined the effect of β-(1,3)-D-glucan with β-(1,6) branches isolated from Aureobasidium...

The killer toxin from Pichia membranifaciens CYC 1106, a yeast isolated from fermenting olive brines, binds primarily to the (1-->6)-beta-D-glucan of the cell wall of a sensitive yeast (Candida boidinii IGC 3430). The (1-->6)-beta-D-glucan was purified from cell walls of C. boidinii by alkali and hot-acetic acid extraction, a procedure which solubilizes glucans. The major fraction of receptor a...

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...

The experiment was conducted to evaluate the effect of β-1,3/1,6-glucan on growth performance, immunity and endocrine responses of weanling piglets. One hundred and eighty weanling piglets (Landrace×Large White, 7.20±0.25 kg BW and 28±2 d of age) were randomly fed 1 of 5 treatment diets containing dietary β-1,3/1,6-glucan supplemented at 0, 25, 50, 100 and 200 mg/kg for 4 wks. Each treatment wa...

Developing cotton (Gossypium hirsutum) fibers, cultured in vitro with their associated ovules, were used to compare the effects of two herbicides that inhibit cellulose synthesis: 2,6-dichlorobenzonitrile (DCB) and an experimental thiatriazinebased herbicide, CGA 3259615. CGA 3259615 in nanomolar concentrations or DCB in micromolar concentrations causes inhibition of synthesis of crystalline ce...
