Conversion of Enantiomers during the Separation of Acetoin from Fermentation Broth

Fermentation, 2022
Acetoin (AC) is an important platform compound with two enantiomers (R)-AC and (S)-AC. Due to its unique spatial structure, optically pure AC has particularly high application in asymmetric synthesis.
