詳細

詳細

GranuCult^® plus Letheen-Broth Base modified is highly nutritious containing Lecithin and Tween^® 80 for neutralizing quaternary ammonium compounds. Beef extract and tryptone provide nitrogen, carbon, sulfur, and other essential growth factors. Glucose is the source of energy. These media are modifications of the AOAC formulae. Letheen Broth Base is used for determining the phenol coefficient of quaternary compounds.

アプリケーション

GranuCult^® plus Letheen-Broth Base modified is a unique formulation for determining the bacterial activity of quaternary ammonium compounds.
