Abstract:
The present invention relates to a method for concentrating law titer fermentation broth, and more particularly to a method for concentrating a fermentation broth using forward osmosis. The method comprises: introducing the fermentation broth and an osmolyte into a feed chamber and a draw chamber, respectively, which are included in a concentration system and are divided from each other by a forward osmosis membrane, and subjecting the introduced fermentation broth to forward osmosis, thereby concentrating the fermentation broth in the feed chamber. The method can maximize the concentration of the low titer fermentation broth while minimizing energy consumption and operating cost, and thus can contribute to the industrialization of new technology.
