描述

一般說明

Half FRASER (Demi FRASER) broth has high nutrient content and the large buffer capacity that creates optimum growth conditions for Listeria. Lithium chloride, nalidixic acid, and acriflavine hydrochloride largely inhibit the growth of accompanying bacteria. Esculin and ammonium iron (III) citrate enables the detection of the β-D-glucosidase activity by the formation of a black complex of esculetin with iron (III) ions. However, this reaction is not exclusive to Listeria sp. and hence every primary and secondary enrichment in FRASER broth has to be sub-cultured on selective plating media.

應用

Half FRASER (Demi FRASER) broth with supplements is used for the primary selective enrichment of Listeria sp. from food and animal feed as well as from environmental samples and other materials.
