These characteristics, together with the mild conditions required for bioconversions, led to the development of high yield biological production processes,
which are more environmentally friendly than their chemical synthesis counterparts, a feature that is presently a major concern of industrialists. Although some of these bioconversions are well-established,
efforts are ongoing in order to increase the efficiency of the existing processes as well as to identify new potentially useful bioconversions.
In this work an overview of recent developments on the use of microorganisms for steroid production is presented.
