It was found that yeast strains designated as M1, M2 and D-2 most efficiently fermented
thick juice worts inoculated with yeast cream at a rate of 2 kgm3 of wort. Fermentation
processes lasted for approximately 2 days and ethanol yield approached 92e94% of the
theoretical yield. Fermentations of green syrup worts were most efficient (ethanol yield
reached 90e92% of the theoretical yield) when these processes were carried out by yeast
strains M1, M2, D-2 and As4 (inoculum e 2 kgm3 of wort).
