General description
脱水纯化的新鲜胆汁，在胆汁培养基中用作选择性抑制剂。牛胆汁干粉是通过低温脱水制备而成，可确保产品的均匀性，并解决了供应新鲜胆汁时遇到的问题。8% 至 10% 胆汁干粉溶液相当于新鲜胆汁。1 克干燥的牛胆汁相当于 8 克新鲜胆汁。
Application
Ox bile is used as a selective agent in culture media for selective growth of intestinal bacteria like E. coli, other feacal coliforms, feacal streptococci. But it is also used as a selective agent in media for detection of Yersinia enterocolitica, Aeromonas hydrophila and Vibrio species. Bile salts may be used as one of the selective agents to prevent the growth of injured Escherichia coli cells, in an experiment done to identify the specific agent in the selective media which would inhibit the growth of the injured Escherichia coli ML30 cells. It may also be used for identification of isolates of Vibrio vulnificus (Beneckea) which is a halophilic bacterium, found responsible for causing several human infections.
