How to Identify Enterococcus Using the Litmus Milk Decolorization Test

The litmus milk decolorization test is a rapid inexpensive technique to assist in the identification of enterococci. It is based on the ability of most strains of Enterococcus species to reduce litmus milk by enzyme action as shown by decolorization of the litmus. Note: Enterococci can also be identified using an Aesculin Hydrolysis Test    Principle Behind the Litmus Milk Decolorization Test A heavy inoculum of the test organism is incubated for up to 4 hours in a tube containing litmus milk. Reduction of the litmus milk is indicated by a change in colour of the medium from mauve to white or pale yellow.   Requirement Litmus Milk Reduction-   No. 50   Method 1. Using a sterile loop, inoculate 0.5 ml of sterile litmus milk medium with the test organism. Important: A heavy inoculums of the test organism must be used. Scraping the loop three times across an area of heavy growth is recommended.   2. Incubate at 35 – 37oC for up to 4 hours, examining at half hour intervals for a reduction reaction as shown by a change in colour from mauve to white or pale yellow (compare with the positive control).    Note: The incubation time should not be more than 4 hours because some strains of viridans streptococci will reduce litmus milk with prolonged incubation.   Results White or pale yellow-pink colour …….   Suggestive of Enteroccocus No change or a pink colour …………..
