Description

MIO HiVeg™ Medium (Motility Indole Ornithine HiVeg™
Medium) is recommended for the identification of Enterobacteriaceae on the basis of motility, indole production and ornithine decarboxylase activity. Organisms ferment dextrose to form acid, which causes the pH indicator bromocresol purple to change from purple to yellow.Organisms possessing ornithine decarboxylase enzyme, decarboxylate ornithine to putrescine which increases the pH making it alkaline, indicated by a colour change from yellow to purple throughout the medium. Decarboxylase negative reaction is indicated by yellow colour or yellow with a purple band near the top of the medium. The indole produced combines with the aldehyde present in the Kovacs reagentto form a red complex. MIO HiVeg™ Medium is prepared by using vegetable peptones in place of animal based peptones which make the
media free of BSE/TSE risks.
