SODIUM TAUROCHOLATE (A Selective Inhibitory Agent used in Culture Media)

Sodium Taurocholate is a bile salt and often used in some selective microbiological media to inhibit the growth of undesired microbes and favor the growth of the target organisms. By providing a selective growth environment, it enables microbiologists to obtain isolation and differentiation of certain microorganisms from mixed cultures and is considered as essential components in formulations of bacteriological media.
Its selective activity is mainly related to its detergent effect, which can disrupt some cellular functions in sensitive cells. Sodium Taurocholate is especially effective for suppressing the growth of certain bacteria and allowing the growth of more resistant species, thereby increasing the selectivity of the medium. As a bile-derived substance, it also plays a role in media that simulate the conditions of the gastrointestinal environment. Due to its consistent selectivity, Sodium Taurocholate is the standard in the diagnostic and research laboratories as well as food, water and pharmaceutical microbiology laboratories where selective recovery and precise microbial identification is critical.
