Abstract

U novije vrijeme istraţuje se primjena ne-Saccharomyces kvasaca u različitim biotehnološkim procesima kao što su proizvodnja poliola, enzima i dr. kemikalija. U ovom radu odreĎivana je fermentacijska sposobnost dva ne-Saccharomyces kvasca, Pichia kudriavzevii ZIM 3106 i Schwaniomyces polymorphus ZIM 2980 u podlozi s različitim koncentracijama glukoze (10 – 100 g L-1). Dobiveni prinosi i koeficijenti konverzije supstrata u etanol za ne-Saccharomyces kvasce usporeĎeni su s odgovarajućim vrijednostima za kvasac Saccharomyces cerevisiae ZIM 3148. OdreĎen je i utjecaj različitih koncentracija mliječne kiseline (1 – 80 g L-1) na fermentacijsku sposobnost navedenih kvasaca.

Abstract (english)

Recently, the application of non-Saccharomyces yeasts has been investigated in various biotechnological processes, like poliol and enzyme production, etc. Therefore, in this study goal was to determine fermentation ability of two non-Saccharomyces yeasts, Pichia kudriavzevii ZIM 3106 and Schwanniomyces polymorphus ZIM 2980 in medium with different concentrations of glucose (10 – 100 g L-1). Obtained yields and substrate to ethanol conversion coefficients were compared to data obtained for yeast Saccharomyces cerevisiae ZIM 3148. Impact of various concentracions of lactic acid (1 – 80 g L-1) on fermentation ability of tested yeast was also determined.
