“…Phytogenic extracts (Salem et al, 2014b;Cedillo et al, 2014Cedillo et al, , 2015, fibrolytic enzymes (Togtokhbayar et al, 2015;Valdes et al, 2015) and yeast (Elghandour et al, 2014) proved to be good strategies to modulate ruminal fermentation for better feed utilization. Yeast Saccharomyces cerevisiae, live cells (LC) or cells extract (CE) are generally recognised as safe by the US Food and Drug Administration, and they can be legally used as animal feed additives (Kwiatkowski and Kwiatkowski, 2012).…”

“…Yeast CE is a non-antibiotic functional product that is naturally obtained from yeast. Although the composition of yeast extracts is variable, it contains three major constituents: glucan (glucose polysaccharide), mannan (mannose polysaccharide) and a protein fraction (Kwiatkowski and Kwiatkowski, 2012). The content of yeast CE from glucan vary from 1% (Lille and Pringle, 1980) to about 29% (Sedmak, 2006) of the dry weight.…”

“…The content of yeast CE from glucan vary from 1% (Lille and Pringle, 1980) to about 29% (Sedmak, 2006) of the dry weight. The content depends upon the nutritional status of yeast cells, isolation method, analysis method and the phase of growth at cells harvest (Lille and Pringle, 1980;Kwiatkowski and Kwiatkowski, 2012).…”

The effect of Saccharomyces cerevisiae as live cells (LC) or cells extract (CE) on in vitro gas production (GP) kinetics and ruminal fermentation parameters of a total mixed ration (TMR) consisting of commercial concentrate and alfalfa hay [1:1 dry matter (DM)] as a substrate was studied. The TMR was incubated with CE at 1, 2 and 4 mg/g or LC at 0.3, 0.6 and 0.9 mg/g DM for 96 h. Rumen GP was recorded after 6, 12, 19, 24, 48, 72 and 96 h of incubation. Interaction effects were observed (P<0.01) between treatment type and yeast dose for the asymptotic GP and methane (CH4) production. Incubation of yeast CE improved (P<0.01) the asymptotic GP compared to control and LC with greater effects (P<0.01) for the low and the intermediate doses. Yeast CE treatment was more effective (P<0.01) in GP than both of LC and control treatments with greater effect (P<0.01) for the low and the intermediate doses. Treatment type and yeast dose affected (P<0.01) CH4 production, metabolisable energy (ME), and short chain fatty acids (SCFA) without affecting in vitro DM degradability (IVDMD). Higher values (P<0.01) of CH4, ME, SCFA and IVDMD were observed for the yeast CE treatment. It could be concluded that adding yeast S. cerevisiae (CE and LC extract) improved GP and ruminal fermentation parameters, where CE at 0.3 and 0.6 mg/g DM was more effective than the yeast LC.

“…Recent studies offer perspective on the potential of ZnO nanoparticles utilization as supplement in order to increase active production of β-glucosidase -enzyme of S. cerevisiae with industrial value, as well as to increase production of baker's yeast (Ban et al, 2014). Saccharomyces cerevisiae yeasts and their metabolites inclusive components of cellular wall are considered as safe materials by US Food and Drug Administration (FDA, 1997) and could be used legally as food ingredients and food supplements (Kwiatkowski et al, 2012). β-glucans obtained from yeasts serve as components of industrial bioproducts such as BetaRight® and WGP® (Biotheras, Inc.) proposed for application as ingredients of baking, drinks, yogurts, juice, chocolate and thickening agents for salad dressing, ice cream, mayonnaise, sauces and cheeses (Zechner et al, 2009).…”

This paper reports about experimental results concerning the influence of 30 nm ZnO nanoparticles on biomass, carbohydrates, β-glucans, proteins accumulation and catalase enzyme activity at Saccharomyces cerevisiae CNMN-Y-20 yeast strain exposed to alcohol action. Alcohol in concentrations of 2%, 5% and 10% added to culture medium has been reported to stimulate β-glucans biosynthesis and to inhibit protein synthesis. Low biomass production, with 71% less that control, was detected in the experiments with 10% alcohol. ZnO nanoparticles in combination with alcohol do not offer sufficient protection for the proteins biosynthesis, but efficiently protect the carbohydrates and β-glucans biosynthetic processes, which contents in the biomass are with 16.6% and 19.9% higher than control, respectively. The maximum value of β-glucans content was established in case of cultivation of selected yeast strain on YPD medium supplemented with 5 mg/L nanoparticles ZnO and 2% alcohol. The obtained results allowed the elaboration of new procedure for directed synthesis of β -glucans that contributed to an increase of this component with 30.7%, compared to control.

“…The response of β-glucan in vertebrates begins with its recognition by receptors present on the cell surface of various immune cells, such as macrophages, neutro-phils, dendritic cells, and natural killer cells (NK), and receptors have also been described presently as non-immune cells, endothelial cells, fibroblasts, alveolar epithelial, and Langerhans cells [20]. The various receptors present on the cell membranes of immune cells related to the recognition of β-glucan in vertebrates are dectin-1, complement receptor 3 (CR3), lactosylceramide receptor, Toll-like receptor 2 (TLR-2), and scavenger receptors [24,25]. The dectin-1 is a type II transmembrane protein with receptor extracellular domain CDR which is responsible for carbohydrate recognition, and a cytoplasmic tail with immunoreceptor ITAM (tyrosine-based activating motif) involved in superoxide production by macrophages in response to the immunosystem defense.…”

Yeasts are a potential source for prebiotic β-glucans. This polysaccharide is characterized by D-glucose monomers linked by β-glycosidic bonds. There are significant structural differences in β-glucans depending on the source and method in which they are obtaining. This polymer is a healthier food and feed additive. Numerous beneficial effects have been attributed to this polymer, in particular immunomodulatory action. Different studies confirm safe use and applicability of β-glucans in medicine for the treatment of diseases (cancer, infections, respiratory diseases) and reduction in glucose and cholesterol levels. Many advances in the processes to obtain β-glucans have been presented, including extraction, purification, and chemical modification, aiming the biological properties and yield. One limitation of their use is the cost, so a strategic discussion of the use of yeast biomass was performed for the production of β-glucans. An extensive and systematic review was undertaken to contribute to the science and technology to obtain β-glucans and their use in different applications.
