Description
General description
GranuCult® prime Enterobacteriaceae Enrichment Broth - Mossel is designed for selective enrichment of bile-tolerant, Gram-negative bacteria from non-sterile pharmaceutical products. D (+) Glucose enhances the growth of all Lactose-positive and -negative Enterobacteriaceae. The undesired, accompanying bacterial flora is completely inhibited by brilliant green and ox bile. The strong buffering capacity of the culture medium prevents the formed acid from killing the culture.
Application
GranuCult® prime Enterobacteriaceae Enrichment Broth - Mossel is suitable for sterility testing of substances, preparations, and products as well as a pre-enrichment broth for the test for specified microorganisms or total viable aerobic count determinations using the MPN method within non-sterile pharmaceutical products.
