HiCrome Chromogenic Coliform agar (CCA Agar) ,

About HiCrome Chromogenic Coliform agar (CCA Agar) ,

• ColiformsProduce pink colonies due to the cleavage of one chromogen by the enzyme -galactosidase
• Escherichia coliProduce dark blue to violet colonies due to the cleavage of both chromogens by the enzymes -galactosidase and -glucuronidase

• The medium contains nutrients like peptone special and sodium pyruvate to help organisms grow
• Sodium lauryl sulfate inhibits gram-positive organisms
• L-Tryptophan improves the indole reaction, which increases detection reliability

• To confirm E. coli, add a drop of Kovacs reagent to the dark-blue to violet colony
• If the color turns cherry-red, the reaction is positive

• Store in a tightly closed container between 15-25C
• Use before the expiry date on the label
