| titleOfInvention | Method for extracting and isolating rifamycin o from fermentation broths of rifamycins |
| abstract | 1. A METHOD FOR EXTRACTING AND ISOLATING RIFAMYCIN O FROM A FERMENTATION BROTH OF RIFAMYCIN CONTAINING RIFAMYCIN B COMPRISING: FILTERING SAID BROTH TO OBTAIN A CLEAR LIQUID; BRINGING SAID CLEAR LIQUID TO A TEMPERATURE WITHIN 1525*C., AND TO A PH WITHIN 4.0-7.5; TREATING SAID CLEAR LIQUID WITH AN OXIDIZING AGENT SELECTED FROM THE GROUP CONSISTING OF SODIUM NITRITE, SODIUM PERSULPHATE, AND HYDROGEN PEROXIDE TO CONVERT SAID RIFAMYCIN B TO RIFAMYCIN O, A PRECIPITATE INSOLUBLE IN THE TREATED CLEAR LIQUID; AND SEPARATING SAID PRECIPITATED RIFAMYCIN O FROM THE TREATED CLEAR LIQUID. |
