PHENOL LACTOSE BROTH (ISO 9308-1-2014)

Description

Lactose fermentation is a characteristic that is of great practical importance in the primary isolation of pathogenic enterobacteria. This single characteristic makes possible an immediate presumptive distinction between the intestinal commensals of various genera which ferment lactose and those of the intestinal pathogens i.e. Salmonella, Shigella, which do not ferment lactose. Phenol Red Lactose Broth is formulated as recommended by ISO Committee for studying lactose fermentation by coliforms, which is an important differentiating characteristic for the members of Enterobacteriaceae.
