    摘要: A biological process for producing steroids hydroxylated at the 25-position thereof comprises adding steroids (excluding cholesterol) to the cells or culture liquid of a microorganism of the genus Amycolata or Sphingomonas capable of hydroxylating the steroids at the 25-position thereof to convert a hydrogen atom bonded to a carbon atom at the 25-position of each steroid into hydroxyl group. By this process, steroids(other than cholesterol) can be biologically hydroxylated at the 25-position by using microorganisms other than those of the genus Streptomyces.
