一般描述
Granucult® Modified UVM broth (Base) is suitable for the selective enrichment of Listeria in the two-stage procedure. The combination of various peptones, extracts, salts, and buffer substances enables the good growth of Listeria. The selectivity is due to the antiproliferative substances nalidixic acid and acriflavine hydrochloride. The two-stage enrichment method has demonstrated its value, especially with sample materials (meat and meat products) that are characterized by a high level of accompanying flora.
应用
Granucult® Modified UVM broth (Base) is suitable for the selective enrichment of Listeria in foods and beverages.
