Abstract:
A method of removing color bodies from a fermentation broth includes precipitating a color-forming impurity (color body) by adjusting the fermentation broth to a pH greater than about 13; filtering our precipitated color-forming impurities from the broth; and bleaching a second color impurity by treating the broth with an oxidizing agent.
