• Ready to use:E. coliscreen tubes and Kovac’s Indole Reagent.
• Easy interpretation:Visible colour changeE. coli Screen w/Kovacs contains E. coli Screen Tubes and Kovac’s Indole Reagent. The E. coli screen tubes contain Columbia Agar, tryptophane and ρ-nitrophenyl β-D-glucopyranosiduronic acid (PGUA). PGUA is a colorless compound that is hydrolyzed by β-glucuronidase to form nitrophenyl, a yellow compound. In the indole test, tryptophanase enzyme attacks the side chain of tryptophan and leaves an aromatic ring in the form of indole. This reaction occurs as a condensation process that is formed by an acid splitting of the protein molecule. The ρ-dimethylaminobenzaldehyde in Kovacs reagent then combines with indole to form a red color complex^5,6.Not all products are available for sale in all territories.
