Compact Dry YM | Yeast and Mold

Compact Dry YM plates offer a straightforward way to track spoilage fungi and airborne contamination throughout food, beverage, and personal-care production. Each pre-sterilized dish contains a dehydrated, fungus-selective medium that re-hydrates on contact with 1 mL of sample or rinse liquid. Yeasts grow as smooth blue to cream colonies and molds develop characteristic filamentous colonies with species-specific colors and textures. The chromogenic background stays pale, so counts are easy. Compact Dry YM streamlines yeast and mold testing—delivering clear, reliable results that keep shelf-life studies, sanitation checks, and product quality programs on target. Key Benefits AOAC Performance Tested Method – validated for regulatory confidence. True “open → inoculate → incubate” workflow – no agar prep, spreading, or autoclaving. Wide environmental tolerance – detects xerophilic and osmophilic fungi that survive low-water-activity foods and dry processing zones. Ideal for air, surface, and product testing – supports GMP environmental monitoring and FDA release criteria for finished goods. Ambient-stable & stackable – store at 1 – 30 °C; slim plates maximize incubator capacity. Clear visual differentiation – colored yeasts vs. filamentous molds streamline colony classification and photo records. Incubation parameters Temperature Time 25 ± 1 °C 3 – 7 days pH tip: Adjust the product (or a 1 : 10 dilution) to pH 6 – 7 with 0.1 – 1 N NaOH (acidic) or HCl (alkaline) to ensure optimal colony development. Performance Countable range: 1 – 300 CFU per plate (1 mL inoculum).
