Method for purifying fermentation broth |
abstract |
A process for purifying statin compounds from a fermentation broth by extraction and crystallization is disclosed. A fermentation broth is subjected to a pretreatment procedure which involves an alkaline pretreatment and an alkaline purification. Following the pretreatment procedure, the statin compound is extracted under acidic conditions into a hydrophobic solvent and purified by crystallization. The organic extraction solvent is concentrated and then extracted with a mild base. The statin compound is then purified by crystallization. |
