| abstract |
In the separation of microorganisms from fermentor growth media, a separating agent such as an alcohol, is added to the fermentor effluent to facilitate separation of the cellular material. A portion of the spent media and separating agent is recycled to the fermentor as carbon energy source therein. Further alcohol separating agent is separated from the balance of the spent media and reused for separation purposes or for use in the fermentor. |
