“…From this point of view, the feed admixture containing beta-glucan used in our experiment meets all the criteria [19,20]. It is generally known that beta-glucans, as matters of natural origin, have potential immune-modulating effects [21]. Their bond to specifi c receptors stimulates the activity of phagocytes and triggers signal cascades leading to expression of cytokines and chemokine genes, which was confi rmed in piglets in several in vivo and in vitro studies [18,22,23].…”

The aim of this paper was to study the immunostimulating effects of feed additive containing beta-glucan given to pregnant sows and consecutive specific immunomodulation by vaccination of their suckling piglets. Thirty-five suckling piglets from the control and experimental group of sows were divided into four groups. Selected blood indices of immune profile (TIg, IMA, SI), specific antibodies against Lawsonia intracellularis formed in the blood serum of suckling piglets after vaccination, as well as production indices were observed. In all the groups, birth body weights were similar. After weaning, average daily weight gains were significantly higher (p < 0.05) in the group of vaccinated suckling piglets, as well as in suckling piglets from experimental sows. The same trend was recorded in average TIg values. Significant effects (p < 0.01) of beta-glucan and vaccination were observed in the changes of the index of metabolic activity of phagocytes (IMA) and less markedly in the index of stimulation activity of lymphocytes (SI). The least favorable results were observed in the group without both vaccination and beta-glucan. The effect of vaccination was manifested by ELISA estimation of specific antibodies (PI), when in both non-vaccinated groups (A and D) we observed minimum antibodies levels compared with vaccinated groups (B and C), which showed a high positivity without significant differences between the beta-glucan stimulated (C) and the non-stimulated group (B). These results suggest that beta-glucan given to sows and consecutive vaccination of suckling piglets can stimulate their non specific and specific immunity.

“…First, numerous scientific studies [34,35] have shown some beneficial effects when β-glucan was given in combination with vitamin C. The main reason why vitamin C shows synergistic effects is due to the fact that this vitamin has been shown to stimulate the exact same immune responses as β-glucan, i.e. macrophage activities-NK cell activity and specific antibody formation.…”

Abstractβ-glucans belong to a group of biologically active natural compounds called biological response modifiers. These substances represent highly conserved structural components of cell walls in fungi, yeast, grain and seaweed. Despite almost 160 years of intensive research, the exact mechanisms of their action remain unsolved. The significant role of glucans in cancer treatment, infection immunity, stress reduction and restoration of damaged bone marrow has already been established. The present review focuses on the various less known but potentially significant roles glucans might play in medicine. In summary, glucan might represent the most important natural immunomodulator.

“…The partial replacement of vegetable oil in mayonnaise using β-glucans derived from spent yeast extract has two distinct advantages; firstly, it decreases the calorie content of the emulsification and secondly, it results in the utilisation of industrial by-products (Worrasinchai et al 2006). In addition, β-glucans have been reported to have been used as a form of immunomodulator in livestock (Eicher et al 2006). …”

Production of good quality beer is dependent largely on the fermentation temperature and yeast strains employed during the brewing process, among others. In this study, effects of fermentation temperatures and yeast strain type on beer quality and spent yeast density produced after wort fermentation by two commercial yeast strains were investigated. Beer samples were assessed for colour, clarity and foam head stability using standard methods, whilst the compositions and concentration of Beer Volatile Compounds (BVCs) produced were assessed using GC-MS. The spent yeast density, measured as dry cell weight, ranged between 1.84 -3.157 mg/ml for both yeast strains with the highest yield obtained at room temperature fermentation. A peak viable population of 2.56 x 10 7 cfu/ml was obtained for strain A, also during fermentation at room temperature. The foam head of the beers produced at 22.5ºC was most stable, with foam head ratings of 2.66 and 2.50 for yeast strain A and B, respectively. However, there was no significant (p = 0.242) difference in colour intensity between the beers produced at the different fermentation temperatures. Eight different BVCs were detected in all beer samples and were found to affect the organoleptic properties of the beer produced. Further optimizations are required to determine the effects of other parameters on beer quality.
