Frontiers in Immunology, 2022 β-glucan has been used as immunostimulant for fish. However, the effect of yeast β-glucan on viral infections has been less studied in fish. In this study, we investigated the effects of β-glucan on the resistance of zebrafish against spring viraemia of ...

Bacterial α-glucan phosphorylases [PDF]
FEMS Microbiology Letters, 1999 Although glycogen and other α-1,4-d-glucan storage polysaccharides are present in many bacteria, only few glucan phosphorylases from bacteria have been identified and characterised on the protein or gene level. All bacterial phosphorylases follow the same catalytic mechanisms as their plant and vertebrate counterparts, but differ considerably in terms ...

Effect of papulacandin B on β-glucan synthesis in Schizosaccharomyces pombe [PDF]
FEMS Microbiology Letters, 1983 The antifungal antibiotic papulacandin β inhibited B(1,3)glucan-synthase activity, in vitro, from Schizosaccharomyces pombe. Levels of β(1,3)glucan-synthase from antibiotic-treated cultures were lower than the control cultures whereas mannan-synthase and β(1,3)glucanase activities were almost unaffected.

The role of ruminal carboxymethylcellulases in the degradation of β-glucans from cereal grain [PDF]
FEMS Microbiology Ecology, 1998 The non-cellulolytic ruminal bacterium, Prevotella bryantii, grew rapidly on water soluble β-glucans, but a mutant deficient in carboxymethylcellulase (CMCase) activity could not. Native activity gels prepared with CMC and β-glucan indicated that the CMCase and β-glucanase activities migrated at similar rates. When a plasmid carrying the P.

Involvement of phosphorylated compounds in stimulation of 1,4-β glucan synthases ofSaprolegnia monoica [PDF]
FEMS Microbiology Letters, 1991 The stimulation by ATP of β glucan synthase activities of cell-free extracts of Saprolegnia monoica was enhanced by the presence of glucose-phosphates. These effects were obtained in conditions of 1,4-β glucan synthesis; on the contrary, strong inhibition was observed during 1,3-β glucan production.

Cyclic diguanylic acid stimulates 1,4-μ-glucan synthase fromSaprolegnia monoica [PDF]
FEMS Microbiology Letters, 1991 Abstract 1,4-μ-Glucan synthase activity, but not 1,3-μ-glucan-synthase activity, from Saprolegnia monoica was stimulated by cyclic-diguanylic acid, an immediate activator of Acetobacter xylinum - cellulose synthase. This activator, which increased the V max without modifying the K m for UDP-glucose, was active on solubilized and partially ...

Indirect Measurement of β-Glucan Content in Barley Grain with Near-Infrared Reflectance Spectroscopy
Foods, 2022 β-Glucan is a component of barley grains with functional properties that make it useful for human consumption. Cultivars with high grain β-glucan are required for industrial processing.

Immunotoxicity of soluble β-glucans induced by indomethacin treatment [PDF]
FEMS Immunology & Medical Microbiology, 1998 (1 --> 3)-Beta-D-Glucan (beta-glucan) is a biological response modifier that regulates host immune response. However, the side effects of this drug have not been extensively examined. In this study, we found that the combination of a beta-glucan and a nonsteroidal anti-inflammatory drug, indomethacin, induced lethal toxicity in mice. Lethal toxicity of

Divergence of barley and oat varieties according to their content of β-glucan [PDF]
Journal of the Serbian Chemical Society, 2017 Barley and oat have been promoted for years as good sources of dietary fiber, especially β-glucan. Studies have shown a positive effect of barley and oat β-glucan on human health and as a result, there has been an increasing demand for β-glucans in the ...

Detection of peptidoglycan and β-glucan with silkworm larvae plasma test [PDF]
FEMS Immunology & Medical Microbiology, 1996 A method to detect peptidoglycan and (1-->3) beta-D-glucan with silkworm larvae plasma (SLP) derived from the hemolymph of the silkworm, Bombyx mori was developed. SLP contains all of the factors of the pro-phenol oxidase cascade, an important self-defense mechanism of insects.
