Application

GranuCult® prime Violet Red Bile Lactose (VBRL) agar is suitable for the detection and colony counting of coliform bacteria from food and animal feed, water, and other materials.

Disclaimer

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered®culture medi. depending on your needs. The designations basi. plu. or prime are added to indicate the quality control leve. 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 VRB (Violet Red Bile Lactose) agar is used for the detection and colony counting of coliform bacteria. Crystal violet and bile salts inhibit the growth of the Gram-positive accompanying bacterial flora. Degradation of lactose to acid is indicated by the pH indicator neutral red, which changes its color to red, and by precipitation of bile acids. The enzymatic digest of animal tissue provides carbon and nitrogen sources for bacterial growth. Yeast extract primarily supplies the B-complex vitamins, while agar is the solidifying agent.

Other Notes

  • The prepared medium is clear and red
  • If the medium is to be used immediately for the poured plate technique, cool it to 44-47 °C in a water bath before use
  • If the medium is used for the surface plating technique, there should be no visible moisture on the plates before use
  • The prepared plates can be stored at 2 °C to 8 °C in the dark and protected against evaporation for up to 5 days
