  Rezumat:  Researches Concerning the Growth Dynamic and Glucides Fermentation with Saccharomyces cerevisiae Strains Used in Spirt Industry. We have determined the dynamic of the growth and the fermentation of glucides in four natural media (hopsless malt wort, apple juice, cyder and maize mash) on a spirit strain of Saccharomyces cerevisiae. The fermentation speed was estimated depending on the quantity of formed CO2 related to the volume unit (g CO2 relesead by 1 l medium in one hour). The alcohol quantity was calculated. In order to determine the multiplication speed, the Km coefficient was calculated. It indicates the numer of new cells formed during one hour. It was determined also, the glucose consumption. It was established that among the 4 natural media indicated above, the highest alcohol production was obtained on the hopsless malt wort, followed by the cyder and the maize mash, respectively. The fewest alcohol production was obtained in the apple juice medium. As it concerns the glucose consumption, the medium with 8.4% glucose provided an appreciable growth of spirit yeast, while for the other two concentrations (2.1% and 21.5%) an inadequate growth was observed, that means a complete consumption after 24 hours or that it produced a substrate inhibition phenomenon.
