Characteristics of biomass and mineral yeast saccharomyces cerevisiae using soybean meal and fish meal

The research aimed to analyze the characterization and mineral content of Saccharomyces cerevisiae using soybean meal and fish meal media. The method of research used a completely randomized design using three types of yeast (local yeast, peat soil yeast, and yeast of Food Nutrition Culture Collection [FNCC]). The characterization based on biomass has not been different significantly, but the biomass of all yeast with the soybean meal medium was higher than the fish meal medium. The highest biomass was obtained from local yeast followed by FNCC and peat soil yeast. The mineral content of potassium, sodium, calcium, and magnesium in the FNCC yeast was higher when compared to local and peat soil yeast; on the contrary, the iron content of local yeast was higher than FNCC yeast and peat soil yeast. The result of this study recommends the soybean meal medium for Saccharomyces cerevisiae, and in general, the mineral content of FNCC yeast was higher than local and peat soil yeast.
