Chromogenic culture media are used to isolate, identify, and differentiate specific microorganisms from a heterogeneous population. The medium contains chromogenic substrate which is utilized by the microorganisms to give colored colonies that is specific for each microorganism. The cover story of this month titled: “Everything You Need to Know About Chromogenic Media” contributed by HiMedia Laboratories Pvt Ltd. Chromogenic media can target and differentiate microbes with high specificity by inducing chromogenic enzyme-substrate reactions targeting specific microbial enzymes. It exploits the capacity of the microbes to process the specially designed substrates in its own unique enzymatic way thereby releasing a chromogen The colored component of the chromogenic substrate generating a unique color identity for them.  The edition has a featured article entitled “Mikromol featured product: Apomorphine Hydrochloride Hemihydrate” contributed by Mikromol™ reference standards.
