Mueller Kauffman Tetrathionate Novobiocin Broth is used for improved enrichment and isolation of Salmonellae.

Suspend 89.42 grams of dehydrated mediumI in 1000 ml distilled water. Heat the medium just to boiling. DO NOT AUTOCLAVE. Cool to 45-50℃ and just before use aseptically add 20 ml of iodine solution (20 gram iodine and 25 gram potassium iodide in 100 ml sterile distilled water) along with rehydrated contents of 1 vial of MKTT Novobiocin Supplement (Cat. No. 79894). Mix well to disperse calcium carbonate uniformly before dispensing in sterile tubes.
Note: Due to presence of calcium carbonate, the prepared media forms opalescent solution with white precipitate.

We offer two media types: the superior granulated GranuCult^® and the cost-efficient powdered NutriSelect^® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
