The studies showed that the selected system (TOA and OAL)
was effective for the extraction of lactic acid from aqueous solutions
and simulated fermentation broth. All the variables that affected
the extraction of lactic acid were investigated to get the suitable conditionAfter the extraction of lactic acid, the extracted two enantiomers
of lactic acid were applied to investigate the enantiomeric
analysis and separation by ligand exchange chromatography and a
conventional method was established. The combination of extraction
and enantiomeric separation was established as a convenient
system for the procedure of recovery of (D, L)-lactic acid from fermentation
broth.
