2008 Yeast Mold Broth, Condalab

YM Broth provides a nutrient-rich liquid environment designed to maximize the biomass of fungal cultures. The Peptone and Yeast Extract serve as primary sources of nitrogen, amino acids, and essential B-complex vitamins. Malt Extract contributes additional carbohydrates (primarily maltose) and growth factors that are particularly effective for the rapid proliferation of fungi. Dextrose (Glucose) is included at a high concentration to provide an immediate energy source. The combination of these ingredients supports the growth of even the most fastidious yeasts and molds. Like the agar version, this broth can be rendered selective against bacteria by lowering the pH through the addition of organic acids after sterilization.

Advantages

• High Biomass Production: Ideal for the enrichment of samples with low initial fungal loads or for the large-scale propagation of yeast cultures.
• Standardized Wickerham Formula: Follows the classic formulation for the maintenance and classification of yeasts and molds.
• Liquid Enrichment: Effective for testing liquid food products, beverages, or environmental swabs where a pre-enrichment step is required.
• Flexible Selectivity: The medium can be adjusted to a lower pH (e.g., pH 3.0–4.0) to suppress bacterial growth in heavily contaminated samples.
• Versatile Use: Used extensively in brewery laboratories for the detection of wild yeasts and in pharmaceutical labs for fungal limit testing.
