THE CONTENT OF BIOLOGICALLY ACTIVE ELEMENTS IN THE DANDELION EXTRACT AND ITS IMPACT ON THE PHYSIOLOGY OF YEASTS SACCAROMYCES CEREVISIAE
The results of studies on the content of biologically active substances in the dandelion extract, obtained by the plants' pressing, are described in the article. The effect of the dandelion extract on the yeasts Saccharomyces cerevisiae physiology has also been studied. The applied dose of the extract was determined by evaluation of its impact on the morphological characters and physiological condition of yeasts in the process of yeast-generation. It is ascertained that the optimum dose of the extract to be applied is 0.4 of the total amount of yeast suspension. The general amount of volatile alcohol impurities was reduced in the process of the wort fermentation with the activated yeasts. The content of such components of fusel oil as isobutanol and isoamilol was reduced to the greatest extent.
