三号胆盐（OXOID分装）

BILE SALTS NO.3

Oxoid Bile Salts No.3 was developed to meet the demand for a refined bile salt for use as a selective inhibitory agent in bacteriological culture media. 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.

3号胆盐
为满足细菌培养基对精制胆盐作为选择性抑制剂的需求，研制了氧类胆汁盐3号。它由一种经特殊修饰的胆汁酸盐组成，其效力低于通常引用的胆盐浓度的三分之一。常用在选择培养基中，如麦康基琼脂3号、SS琼脂和结晶紫中性红胆盐琼脂，3号胆盐是最佳浓度为0.15%w/v。
