WebThe chromogenic substrates Salmon-GAL and X-glucuronide enable easy differentiation and enumeration of Escherichia coli and coliform bacteria, as both use characteristic enzyme combinations to cleave these substrates and grow as distinct coloured colonies. WebThis enzyme breaks down the substrate into two products, one of which produces the color change that aids in the final visual detection, which is where we get the term chromogenic . Chromogenic means related to color. Since this detection assay relies on a visible color change, we get the full term, “chromogenic assay.”
