Description générale

GranuCult® plus Rose-Bengal Chloramphenicol Agar is a selective agar for the enumeration of yeasts and molds in foodstuffs. The neutral pH in combination with chloramphenicol suppresses the growth of most bacteria. Rose-Bengal, taken up intracellular by fungi, restricts the size and the spreading of molds, preventing the overgrowth of slow-growing species by luxuriant species.

Application

GranuCult® plus Rose-Bengal Chloramphenicol Agar is suitable for the enumeration of yeasts and molds in foodstuffs, particularly proteinaceous food.

Caractéristiques et avantages

  • 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
