<description xml:lang='ro' descriptionType='Abstract'>În acest studiu sunt reflectate rezultatele optimizării mediului de cultivare pentru Saccharomyces cerevisiae CNMN-Y-20 în vederea sporirii conţinutului de β-glucani. Evidenţierea ingredientelor mediului de cultivare cu efect stimulator (cum ar fi sursa de carbon şi acetatul de zinc) a fost efectuată aplicând algoritmul Yates. Concentraţiile componentelor mediului de cultură optimizat sunt, g L-1: zaharoză – 37,0; (NH4)2SO4 – 3,0; MgSO4•7H2O – 0,7; NaCl – 0,5; Ca(NO3)2 – 0,4; KH2PO4 – 1,0; acetat de zinc – 0,00816; autolizat de drojdii – 10 ml. Mediul optimizat utilizat pentru cultivarea tul-pinii de drojdie se caracterizează prin obţinerea a 29,47±0,52% β-glucani în biomasa uscată, sau cu 31,8% mai mult decât mediul iniţial.</description>
<description xml:lang='en' descriptionType='Abstract'>This paper contains results of optimization of culture medium for Saccharomyces cerevisiae CNMN-Y-20 with aim to increase β-glucans content. The selection of components of culture medium (carbon sources, zinc acetate) with sti-mulatory effect was carried out by applying the Yates algorithm. Concentrations of optimized culture medium compo-nents g L-1: saccharose – 37,0; (NH4)2SO4 – 3,0; MgSO4•7H2O – 0,7; NaCl – 0,5; Ca(NO3)2 – 0,4; KH2PO4 – 1,0; zinc acetate – 0,00816; yeast autolysate – 10 ml. Optimized medium used for cultivation of yeast strain is characterized by obtaining 29,47 ± 0.52% β-glucans per dry biomass or 31,8% more than the original medium.</description>
