Differentiate enteric gram-negative bacilli using InMicro® Prepared: Motility Indole Lysine Medium (MIL Medium).
Differentiate enteric gram-negative bacilli using InMicro® Prepared: MIL Medium based on motility, production of indole, lysine deamination and lysine decarboxylation. MIL Medium was described by Reller and Mirrett in 1975 to facilitate early recognition and presumptive identification of members of the family Enterobacteriaceae.
Differentiate enteric gram-negative bacilli based on motility, production of indole, lysine deamination and lysine decarboxylation using MIL Medium.
This medium contains peptones and tryptones that supply nitrogenous compounds and amino acids necessary for enteric gram-negative bacilli. Yeast extract is a source of B-complex vitamins and dextrose is an energy source. Agar is added to enable the detection of motility. Brom cresol purple is a pH indicator that is purple at the initial pH of the medium. Enteric gram-negative bacilli ferment dextrose, producing acid that changes the pH indicator color to yellow and stimulates enzyme activity. Lysine is decarboxylated by some enteric bacteria into cadaverine. This produces a purple butt in the tube because the pH indicator reverts to purple. Lysine deamination produces α-ketoglutaric acid that results in a deep red rim at the surface of the medium and a yellow butt in the tube. Indole is produced by organisms that possess the enzyme tryptophanase which degrades tryptophan present in the medium. This reacts with Kovas reagent and forms a red complex.
Manufactured at a cGMP-compliant facility under the ISO 13485 standard, ensuring high-quality manufacturing standards, consistency, and reliability for both research and industrial settings.
