说明
一般描述
GranuCult® plus DEV Lactose peptone broth is suited for the enrichment ａnd determination of the titer of coliform bacteria in the bacteriological analysis of water according to the German standard methods for the examination of water ａnd the previous German regulations from 1990.Casein peptone ａnd soya peptone provide nitrogen, vitamins, minerals, ａnd amino acids for growth, while sodium chloride ensures osmotic balance. Lactose is a carbohydrate source. The pH indicator bromocresol purple is yellow below pH 5.3 (acidic) ａnd purple above pH 6.7 (alkaline). The fermentation of lactose ａnd the consequent acid production changes the color of the medium to yellow.
应用
GranuCult® plus DEV Lactose peptone broth is suitable for the enrichment of coliforms in the bacteriological analysis of water.
