United States Biological Corporation YEAST NITRGEN BSE W/O AA 500GR
Supplier: United States Biological Corporation Y2025500G
Yeast Nitrogen Base (YNB) media have been prepared according the formulae of Wickerham (1943-51) and Burkholder (1943). YNB is a well defined composition of salts, vitamins, amino acids and a nitrogen source for a vigorous growth of Sacharomyces cerevisiae. Yeast Nitrogen Base without amino acids (YNB w/o AA), Y2025, is used for selecting yeasts based on amino acid and carbohydrate requirements. In Y2025, Ammonium Sulfate is included as a readily available nitrogen source for nitrogen assimilation. The medium includes all other vitamins, mineral salts and trace elements required for a vigorous growth of yeast cells. Compared to full YNB medium, Y2025 lacks Histidine, Methionine and Trypthophan. In combination with €œDrop Out € medium supplement mixtures, Y2025 provides an excellent medium to cultivate and select auxothophic strains of yeast that requires the addition of essential nutrients like amino acids and/or vitamins.
