FORFARANDE FOR INTENSIFIERING AV DEN MIKROBIOLOGISKA OMVANDLINGEN AV STEROIDFORENINGAR

Microbiological conversions of cyclodextrins are intensified by adding to the reaction mixture 0.2 to 3 moles of alpha -, beta - or gamma -cyclodextrin or an optical mixture thereof pro mole of the steroid substrate, before, at the beginning or during the conversion. The cyclodextrin if desired, can...

Zusammenfassung:Microbiological conversions of cyclodextrins are intensified by adding to the reaction mixture 0.2 to 3 moles of alpha -, beta - or gamma -cyclodextrin or an optical mixture thereof pro mole of the steroid substrate, before, at the beginning or during the conversion. The cyclodextrin if desired, can be removed after the reaction. In this way the reaction velocity can be increased, the reaction time is reduced, the substrate concentration in the solution, i.e. its solubility is increased or the so called product inhibition may be avoided. In certain cases of more alternatives the desired reaction can be catalyzed and in this manner the selectivity is increased.
