Overview
Porcine Bile Salts is a kind of sodium bile salt refined from pig bile. It works by reducing the surface tension at the interface between the culture medium and bacterial pellicle, disturbing cell membranes, and thus accelerating bacterial autolysis. When the pH value is below 6.5, porcine bile salt will produce cholic acid precipitates, forming a precipitation ring around colonies. This prevents the outward diffusion of colony pigments and facilitates colony identification. It is widely used as a selective inhibitor in microbial media to inhibit the growth of Gram-positive bacteria.
