| titleOfInvention | Process for the preparation of 3-oxo-delta-1,4 steroids |
| abstract | There is a process for the preparation of 3-oxo-Δ <1.4> steroids from 3-oxo-Δ <4> steroids saturated in the 1,2-position by fermentation with a biocatalyst in which microorganisms of the species Arthrobacter simplex or Bacillus sphaericus are immobilized in crosslinked polyvinyl alcohol partially esterified with acrylic acid, which is characterized in that the biocatalyst is added to an aqueous suspension of the micronized 3-oxo-Δ <4> steroid, the reaction mixture at a temperature of 20 to 40 ° C until the steroid is reacted and then the biocatalyst is mechanically separated from the aqueous suspension of the 3-oxo-Δ <1.4> steroid formed. |
