Chromogenic Medium, Dehydrated, 5.2 g

Conventional procedures for verification of fecal coliforms such as E. coli when fecal contamination is suspected are often laborious and time-consuming. A simple method used to detect and differentiate between E. coli and other coliform bacteria is the use of an indicator for enzymes produced by specific bacteria. This agar medium contains chromogenic substrates that are linked to a dye. When enzymes produced by E. coli act on certain substrates, the reaction produces a pink color in the plated bacterial colonies. A second substrate produces a blue color when acted on by enzymes produced...
