ENDO Agar GranuCult® plus (catalogue No. 104044) is a granulated dehydrated selective medium used in microbiological testing to detect and isolate E. coli and other coliforms. The formulation includes lactose, fuchsin and sodium sulfite to inhibit non-target bacteria and differentiate target colonies by characteristic colour reactions. Suitable for food, beverage, water and environmental microbiology.
ENDO Agar GranuCult® plus, catalogue number 104044, is a granulated dehydrated selective culture medium formulated for the isolation, detection and presumptive identification of Escherichia coli and coliform bacteria. It is based on the classic Endo medium design where lactose fermentation leads to characteristic colony colouration. Sodium sulfite and fuchsin serve as selective and differential agents to suppress Gram-positive bacteria and aid visual differentiation of lactose fermenters. The granulated format improves ease of handling, dissolvability and rehydration compared to traditional powder formulations.
Advantages
- Selective medium suitable for isolation of coliform bacteria and E. coli.
- Granulated formulation improves solubility and handling in laboratory workflows.
- Facilitates differential colour response for lactose fermenters.
- Applicable to food, water, beverage and environmental microbiology testing.
