In this study five industrial Saccharomyces cerevisiae strains were grown in synthetic medium, containing maltose or glucose, supplemented with different nitrogen sources, with or without agitation. All strains were able to grow and efficiently ferment glucose, but not all strains were able to grow and ferment maltose well. Peptone and ammonium sulfate induced improved fermentation for all strains and conditions. Under agitation, as expected, higher biomass accumulation was detected. Casamino acids supplementation induced efficient maltose fermentation for all of the strains under aerated conditions, but differing maltose utilization patterns were observed for the static cultures.
