A nondispersive extraction process for recovery of lactic acid from fermentation broth is being developed. The criteria for selection of solvent, distribution of lactic acid between the aqueous and solvent phases, and the effect of presence of other compounds in the broth, are discussed. Working with a simulated fermentation broth (without cells), a hydrophobic membrane module has been evaluated for its effectiveness as extractor. Back extraction and its role has been demonstrated. A theoretical comparison of this process with electrodialysis shows membrane extraction to be more desirable.
