Mitis Salinarius Agar Base

1. This product is a selective medium for Streptococcus mutans. 2. Selection mechanism: Streptococcus mutans metabolizes sucrose to produce acid. The dye in the medium will cause the colonies to appear dark blue or blue-purple with a rough surface, which distinguishes them from other bacteria. The added potassium tellurite can inhibit the growth of most non-target bacteria (such as non-oral streptococci and some Gram-negative bacteria), thereby enhancing selectivity.
