The substrate specificity of an intact culture ofBacillus megaterium in relation to steroids of the pregnane series with a dihydroxyacetone side chain and without it, and also with steroids containing a 16α,17α-epoxy ring, has been studied.

It has been shown that a culture ofBac. megaterium performs the reduction of a 20-oxo to a 20α-hydroxy group only in the case of Δ4-3-oxo-steroids containing a 16α,17α-epoxy ring.

The necessity of a dihydroxyacetone side chain for the β-reduction of a 20-oxo group has been established.
