General description

GranuCult® plus YGC agar is a selective agar used to isolate yeasts and molds from milk and milk products. The culture medium contains chloramphenicol to suppress accompanying bacterial flora. Unlike other similar culture media with antibiotics (e.g., Oxytetracycline Glucose Yeast Agar), it has the advantage of being fully autoclavable. Once prepared, it is stable for a long time - at least 4 months.

Application

GranuCult® plus YGC agar is suitable for Selective agar for isolating and counting yeasts and molds in milk and milk products.

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
