  • Method for the microbiological conversion of steroids
    Patent number: 4273872
    Abstract: A method is disclosed for the microbiological transformation of steroids, especially cholesterol, by employing culture media which contain hydrocarbons rather than carbohydrates. Paraffinic hydrocarbons, particularly normal paraffins from 15 to 20 carbon atoms, are used as the only carbon and energy sources. SP2T (NRRL B-11, 112), SP3T bis (NRRL B-11, 113), SP5T (NRRL B-11, 114), SP7T/1 (NRRL B-11, 115), SP742XXA (NRRL B-11, 116), SP731RD (NRRL B-11, 117), and SP734D (NRRL B-11, 118) are bacterial strains which can be used to this purpose.
