General description

m-Endo Total Coliform Broth is a dehydrated, selective, and differential medium designed for the detection and enumeration of total coliform bacteria in water samples. The medium is formulated with sodium sulfite and basic fuchsin, which inhibits the growth of Gram-positive bacteria while allowing coliform bacteria to grow. Lactose-fermenting bacteria produce acetaldehyde, which reacts with sodium sulfite and fuchsin to form red colonies. Rapid lactose fermentation results in a metallic sheen on the colonies. Non-lactose fermenting bacteria form colorless colonies.

Application

Type of Test
Bioburden

Microbial Limits
m-Endo Total Coliform Broth is used for testing drinking water to detect total coliforms using membrane filtration techniques. It is suitable for bioburden testing, microbial limits testing, and water monitoring in clinical, environmental, food and beverage, cosmetics, and industrial quality control applications. This media is ideal for laboratories conducting water quality testing and microbial analysis in compliance with standard methods for the examination of water and wastewater.
