Source: This medium is available from Merck.
Preparation of Medium: Add components to
distilled/deionized water and bring volume to 1.0L.
Mix thoroughly. Autoclave for 15 min at 15 psi pres
sure–121°C. Cool to 45°–50°C. Pour into sterile Petri
dishes. The prepared broth is clear and yellowish
brown.
Use: For the detection of E. coli in meats. The medi
um complies with the German-DIN-Norm 10110 for
the examination of meat, with the regulations accord
ing to § 35 LMBG (06.00/36) for the examination of
food and with ISO Standard 6391 (1996) for the enu
meration of E. coli in meat and meat products. The
bile salt mixture of this medium largely inhibits the
accompanying flora not usually found in the intes
tines. Using fluorescence under UV light and a posi
tive indole reaction, E. coli colonies can be identified
among the grown colonies.
