acumedia* Demi-Fraser Broth Base

• Intended Use: Demi-Fraser Broth Base is used with ferric ammonium citrate for the selective enrichment of Listeria species.
• Product Summary: Demi-Fraser Broth Base is a modification of Fraser Broth Base, developed by Fraser and Sperber, and used
for the rapid detection of Listeria from food and environmental samples. In Demi-Fraser Broth Base, the nalidixic acid and
acriflavine concentration have been reduced in accordance with AFNOR guidelines. Listeria species grow over a pH range of 5.0
- 9.6, and can survive in food products with pH levels outside these parameters.9 Identification of Listeria is based on successful
isolation of the organism, biochemical characterization, and serological confirmation.
