Process for the microbial conversion of phytosterols in adrostenodiona and androstadienodiona

摘要

"Process for the microbial conversion of phytosterols in adrostenodiona and androstadienodiona".The present invention relates to a new process for the fermentation of compositions of a phytosterol in androstenodiona (androst - 4 - and - 3:17 - Dione, AD) and / or androstadienodiona (androsta - 1,4 - diene - 317 - Dione, add).The process utilizes the micro organism microbacteria MB 3683,And the appropriate solubilising agents selected as polypropylene glycol or silicone to solubilize the compositions of a phytosterol in high concentrations in the nutrient medium.The inoculum of microbacteria MB 3683 is developed in a nutrient medium comprising molasses furnace refining and inorganic salts.
