INTERMEDIATES IN THE METABOLISM OF STEROIDS BY PENICILLIUM LILACINUM.
Sebek, Oldrich K. (The Upjohn Company, Kalamazoo, Mich.), Lester M. Reineke, and Durey H. Peterson. Intermediates in the metabolism of steroids by Penicillium lilacinum. J. Bacteriol. 83:1327-1331. 1962-Nonproliferating cells of Penicillium lilacinum (Thom) metabolized progesterone successively to 20-beta-hydroxy-4-pregnen-3-one, testosterone, androstenedione, and testololactone. Testosterone and androstenedione were readily interconvertible. 11-alpha-Hydroxyprogesterone was transformed in an analogous way and its intermediate, 11-alpha, 20-beta-dihydroxy-4-pregnen-3-one, was isolated and identified by a combination of microbiological and chemical methods.
