It consists of a specially modified fraction of bile acid salts which is effective at less than one-third of the concentration of bile salts normally quoted. In selective media such as MacConkey Agar No.3, SS Agar and Violet Red Bile Agars the optimum concentration of Bile Salts No.3 is 0.15% w/v. In such media there is a very sharp differentiation between lactose-fermenters and non-lactose-fermenters of enteric origin - permitting the detection of scanty non-lactose-fermenters in the presence of numerous coliforms.精制的胆酸盐
