The most in the history of microbial transformations of steroids had been the synthesis of the hormones of the adrenal gland and of their more powerful and therapeutically selective synthetic analogs.

Studies of the composition of steroids in bovine and other mammalian adrenal glands by Kendall, Reichstein. Two names are of primary importance for the pioneer works in microbial transformations of steroids, that of the Italian worker L.

MAMOLI who first realized the microbial biosynthesis of testosterone from dehydroepiandro­ sterone, and of the American chemist and microbiologist D. PETERSON, who has contributed by his fundamental experiments in microbial hydroxylation of steroids to the position Brand: Springer Netherlands.

Many steroids and sterols are manufactured through microbial action. This chapter discusses nature and uses of Microbial transformations of steroids book and sterols, sex hormones, corticosteroids, saponins, heterocyclic steroids, manufacture of steroids, types of microbial transformations of steroids and sterols, screening for microorganisms and fermentation conditions for Author: Nduka Okafor, Benedict C.

Okeke. Microbial Transformations of Steroids: A Handbook aims to provide those who wish to use microbial transformations of steroids with a single source book starting from to the present. Microbial transforma­ tions of steroids nowadays offer a valuable tool in the preparation of series otherwise difficultly accessible steroid compounds.

Keywords alkaloids biochemistry biological biosynthesis chemistry experiment metabolism microorganism solution structure synthesis.

Microbes find use in the synthesis and production of pharmacologically active steroids. Microbial transformation of steroids was recognised after the successful llα-hydroxylation of progesterone by the fungus, Rhizopus arrhizus.

Two names are of primary importance for the pioneer works in microbial transformations of steroids, that of the Italian worker L. MAMOLI who first realized the microbial biosynthesis of testosterone from dehydroepiandro- sterone, and of the American chemist and microbiologist D.

PETERSON, who has contributed by his fundamental experiments in Brand: M Capek; O Hanc; M Tadra. The microbial transformation of steroids broadly involves oxidation (introduction of hydroxyl groups, splitting of side chains, production of epoxides etc.) reduction (conversion of aldehydes or ketones to alcohols, hydration of double bonds), hydrolysis and ester formation.
