    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.

    摘要: A condensed wire composition containing an extract content of no less than 18% (w/v) is obtained by vacuum condensing a wine at a temperature of 5.degree. to 60.degree. C., preferably 20.degree. to 35.degree. C. to a concentration by at least 8 times as high as the original, retaining the resulting condensate at a low temperature, e.g., 0.degree. to 10.degree. C. to crystallize tartar, and removing the tartar. An initial distillate obtained upon the vacuum condensing of the wine and/or brandy may be added to the condensed wine in such an amount that final product has an alcohol content less than 1% (v/v).
