Abstract
A process for producing D-.beta.-hydroxyalkanoic acids by utilizing microorganisms having an ability of stereospecifically converting alkanoic acids, 2-alkenoic acids or alcohols into D-.beta.-hydroxyalkanoic acids.

A process for producing a D-.beta.-hydroxyalkanoic acid which comprises subjecting a substrate selected from the group consisting of an alkanoic acid, a 2-alkenoic acid and a 1-alkanol aerobically in a liquid medium to the action of a mutant of a microorganism belonging to the genus Candida in the presence of a sufficient amount of a carbon source to supply energy necessary for a conversion reaction, thereby converting the substrate into the corresponding D-.beta.-hydroxyalkanoic acid, said Candida mutant being substantially unable to decompose the D-.beta.-hydroxyalkanoic acid, and recovering the produced D-.beta.-hydroxyalkanoic acid from the liquid medium.
