描述

一般說明

MKTTn (MULLER-KAUFFMANN Tetrathionate Novobiocin) broth is a selective medium suitable for the enrichment and isolation of Salmonella. Tetrathionate in the broth suppresses the growth of coliform and other enteric bacteria. It is produced from thiosulfate by adding iodine to the culture medium. Salmonella, Proteus, and some other species of bacteria can reduce tetrathionate. Calcium carbonate buffers the sulphuric acid, which is generated when tetrathionate is reduced. Bile promotes the growth of Salmonella, but largely inhibits the accompanying bacteria. Brilliant green and novobiocin suppress the growth of primarily Gram-positive bacteria.

應用

MKTTn (MULLER-KAUFFMANN Tetrathionate Novobiocin) broth (base) is used for the selective enrichment of Salmonella from food, animal feed, and other materials.
