Abstract
- Residual brewing yeast is one of the main solid wastes in brewing. Using residual brewing biomass as a source of biologically active substances is an important way of recycling these brewing by-products. According to the literature S. cerevisiae is considered as the promising source of polysaccharides, particularly beta-glucans. Beta-glucans are structural polysaccharides of the yeast cell and perform immune stimulating properties. At the same time, there is too little information about the content of these polysaccharides in brewing yeast of the genus Brettanomyces. The objects of this study were yeast cultures of Saccharomyces cerevisiae and Brettanomyces bruxellensis. In this work, the cultivations of the yeasts were carried out to compare them as possible sources of beta-glucans. The yeasts were cultivated in a simple periodic culture using a laboratory fermenter (Biostat A, Sartorius). As a result, the content of beta-glucans in the yeasts S. cerevisiae and B. bruxellensis biomass was measured by enzymatic method (Megazyme, Ireland). According to the obtained data, the yeast B. bruxellensis contains a higher amount of beta-glucans than the yeast S. cerevisiae.
