Reference media: SABOURAUD dextrose agar
Application
GranuCult® prime Dichloran-rose bengal chloramphenicol agar is suitable for the enumeration of food-spoiling yeasts and molds.
Disclaimer
We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs. The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
Features and Benefits
- GranuCult® offers superior granulated culture media
- Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment
- Excellent wettability, solubility, and free-flowing properties
- Convenient, with minimal component separation and clumping, even under warm or humid conditions
- High batch-to-batch reproducibility
- Prolonged shelf life of up to five years
- High number of test strains exceeding all regulatory demands
- Granulation technology allows many supplements to be included, with no need to add these separately
General description
GranuCult® prime Dichloran-rose bengal chloramphenicol (DRBC) agar is a selective agar for the enumeration of food-spoiling yeasts and molds. DRBC is a modification of Rose-Bengal Chloramphenicol Agar. In comparison to RBC, the medium contains Dichloran (0.002 g/L), the pH is lowered to 5.6 and the Rose-Bengal concentration is cut in half (0.025 g/L). This results in an increased inhibition of bacteria and yeasts. The inclusion of dichloran serves to inhibit the rapid spreading of mucoraceous fungi and restricts colony sizes of other genera, easing the colony count.
