1. 1. 10 different hydroxy steroids were fermented with cultures of Mycobacterium smegmatis in order to test whether they, like cholesterol, are transformed into their fatty acid esters. Planar sterols without additional oxygen functions were esterif

Cholesterol has been isolated as the only sterol present in Streptomyces olivaceus , a species of the order Actinomycetales—which belongs to the bacteria. The demonstration of the occurrence of sterols in bacteria by means of adsorption chromatogra
