Which selective medium is most commonly utilized for isolating Streptococcus mutans?

Explanation

Among the various culture media, Mitis Salivarius Bacitracin agar is the preferred selective medium for isolating Streptococcus mutans due to its ability to inhibit unwanted bacteria while promoting the growth of S. mutans. MacConkey agar, nutrient agar, and tellurite medium are not selective for this organism.
