WebFeb 13, 2024 · Racemic Mixtures (Racimates) A racemic mixture is a 50:50 mixture of two enantiomers. Racemic mixtures were an interesting experimental discovery because two optically active samples can be combined in a 1:1 ratio to create an optically INACTIVE sample. Polarimetry is used to measure optical activity. WebSep 8, 2014 · It was found that some microorganisms could convert only ( R )-1,2-pentanediol in the racemate to the ( S )-enantiomer. Candida parapsilosis produced 27.9 g/l of ( S )-1,2-pentanediol from 30 g/l of the racemate in 24 hr of reaction (molar yield 93%, enantiomeric excess 100%).
