Fermentative production of D(-)- beta - hydroxyisobutyric acid

摘要

D(-)- beta -hydroxyisobutyric acid is produced fermentatively from isobutyric acid or methacrylic acid by the stereoselective action of microorganisms having the ability to convert isobutyric acid or methacrylic acid into D(-)- beta -hydroxyisobutyric acid in an aqueous medium, and D(-)- beta - hydroxyisobutyric acid is recovered from the aqueous medium.
