Honey can be considered an excellent source of carbohydrates for fermentation processes but low concentrations of nitrogen are found in this substrate having therefore a possible need for supplemental. This study aimed to verify the growth profiles of Saccharomyces cerevisiae in honey-must supplemented with pollen or brewers yeast. Were made experiments with concentrations 15-75 g/L of supplements and these were compared to an experiment without addition of supplements. The elemental analysis showed that the amount of nitrogen present in the brewers yeast is 2.85 times higher than the pollen present in the content. In relation to the growth of S. cerevisiae it has been found that the lower concentrations tested led to higher growth both for the pollen as for brewers yeast. The experiments added with brewers yeast reached the maximum growth in 8 hours of fermentation and the experiments added pollen reached the maximum growth in 12 hours of fermentation. The results showed that supplementation favors the cell growth when compared to the experiment without supplementation.

Abstract

Honey can be considered an excellent source of carbohydrates for fermentation processes but low concentrations of nitrogen are found in this substrate having therefore a possible need for supplemental. This study aimed to verify the growth profiles of Saccharomyces cerevisiae in honey-must supplemented with pollen or brewers yeast. Were made experiments with concentrations 15-75 g/L of supplements and these were compared to an experiment without addition of supplements. The elemental analysis showed that the amount of nitrogen present in the brewers yeast is 2.85 times higher than the pollen present in the content. In relation to the growth of S. cerevisiae it has been found that the lower concentrations tested led to higher growth both for the pollen as for brewers yeast. The experiments added with brewers yeast reached the maximum growth in 8 hours of fermentation and the experiments added pollen reached the maximum growth in 12 hours of fermentation. The results showed that supplementation favors the cell growth when compared to the experiment without supplementation.
