| titleOfInvention | Process for the controlled microbial degradation of bile acids |
| abstract | 1. A process for the microbiological degradation of bile acids by aerobic culture of microorganisms in an aqueous medium using a starting material containing bile acids as carbon source for the growth of the microorganisms, characterized in that, for selective degradation of the steroid-C17-carboxyalkyl side chain to the alpha -propionic acid residue and for simultaneous conversion of the steroid-A ring into the 3-oxo-4-ene and/or the 3-oxo-1,4-diene structure, defective microorganism mutants are used which are capable of growth on vegetable or animal sterol compounds containing a C17-alkyl or alkenyl side chain as sole carbon source and which form 3-oxopregna-4-ene-20-carboxylic acid and/or 3-oxopregna-1,4-diene-20-carboxylic acid from those compounds, even in the absence of inhibitors inhibiting degradation of the steroid ring and/or growth. |
