ABSTRACT:
Carboxylic acids are recovered from a fermentation broth by adjusting the pH of a fermentation broth comprised of a carboxylic acid to at least about 6.0 and then heating the pH-adjusted broth to a temperature sufficient to effect the formation of three immiscible phases, one of which is an oily phase rich in the carboxylic acid.
