Application

ENDO agar is suitable for the detection and isolation of E. coli and coliform bacteria in various materials.

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® ENDO agar is a selective medium recommended for the isolation of Escherichia coli and coliform bacteria. Sodium sulfite and fuchsin inhibit the growth of gram-positive bacteria. E. coli and coliform bacteria metabolize lactose with the production of aldehyde and acid. The aldehyde liberates fuchsin from the fuchsin-sulfite compound, the fuchsin then colors the colonies red. In the case of E. coli, this reaction is so intense that the fuchsin crystallizes, giving the colonies a permanent greenish metallic sheen (fuchsin sheen). Lactose-negative and weakly lactose-positive E. coli do not show any fuchsin sheen.

Other Notes

  • The plates are clear and pale pink.
  • If the culture medium is somewhat red after it has solidified, the red coloration can be removed by adding a few drops (max. 1 mL/liter) of a freshly prepared 10 % sodium sulfite solution and then boiling.
  • On exposure to oxygen, the plated culture medium gradually becomes red due to the oxidation of sulfite and can thus no longer be used. It can only be kept for a few days even if it is stored in the dark and at refrigerator temperature.
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.

Preparation Note

Keep tightly closed. Keep in a well-ventilated place. Keep locked up or in an area accessible only to qualified or authorized person.
