ULTRASOUND-ASSISTED AND ENZYMATIC-BASED METHOD FOR ISOLATION OF β-GLUCANS FROM OAT BRAN [PDF]
Biotechnologia Acta, 2023 β-Glucans are a group of non-starchy polysaccharides, or (1,3),(1,4)-β-D-glucans, that can be found in the cell walls of several species of bacteria, algae, lichens, fungi, and cereal grains.

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.

International Journal of Molecular Sciences, 2022 β-glucans are a diverse group of polysaccharides composed of β-1,3 or β-(1,3-1,4) linked glucose monomers. They are mainly synthesized by fungi, plants, seaweed and bacteria, where they carry out structural, protective and energy storage roles.

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 ...

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.

FT-IR Method Limitations for β-Glucan Analysis
Molecules, 2022 β-glucans are known as biological response modifiers. However, different sources can result in structural differences and as a result differences in their biological activity.

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.

Spent Brewer’s Yeast as a Source of Insoluble β-Glucans
International Journal of Molecular Sciences, 2021 In the brewing process, the consumption of resources and the amount of waste generated are high and due to a lot of organic compounds in waste-water, the capacity of natural regeneration of the environment is exceeded.
