Description

Chromogenic substrate for α-D-glucosidase, yielding a blue precipitate. It is used for the detection of, e.g. Staphylococcusaureus and Bacillus species, and the isolation of Enterobactersakazakii e.g., from baby food. It is an indolyl carbohydrate that is the beta-D-glucoside of 3-hydroxy-1H-indole, in which the indole moiety is substituted at positions 4 and 5 by chlorine and bromine, respectively. The enzyme, beta-glucosidase, cleaves the glycosidic bond to give 5-bromo-4-chloro-3-hydroxy-1H-indole, which immediately dimerises to give an intensely blue product.
