L.J. Medium is prepared as per the Jensens modification of the original formulation of Lowenstein. The egg base medium supports a wide variety of Mycobacteria and can also be used for niacin testing. Glycerol provides fatty acids. Malachite green serves as an inhibitor as well as pH indicator. Formation of blue zones indicates a decrease in pH by Gram-positive contaminants (e.g. Streptoccocci) and yellow zones of dye destruction by Gram-negative bacilli. Proteolytic contaminants cause localized or complete digestion of the medium.
