Product Description & Summary
YMEA is an acidic enriched medium used for the detection and enumeration of yeast and molds. The nutritive base consists of casein, malt extract, and yeast extract which provide a carbon, protein, and other nutrient sources required for the growth of many microorganisms. It is suitable for yeasts and molds as it contains a high concentration of maltose and other saccharides as energy sources. The acidic pH of YMEA is optimal for the growth of yeasts and molds, while being slightly inhibitory towards bacterial growth. This media is prepared, dispensed, and packaged under oxygen-free conditions to prevent the formation of oxidized products prior to use.
Interpretation of Results & Limitations
If used properly, YMEA agar will support good growth of many microorganism, including yeast and molds.
YMEA agar will not provide complete information for identification of microorganisms, including yeast and mold isolates. Additional test procedures and media are required for complete identification. This medium may not support the growth of all clinically significant anaerobes. Consult reference materials for additional information.
