Abstract
A method is provided for preparing D(-)-.beta.-hydroxyisobutyric acid by fermentation employing the method and/or ethyl esters of isobutyric acid, the methyl and/or ethyl esters of methacrylic acid, isobutyl isobutyrate and/or isobutyl methacrylate as the substrate and a microorganism of the genus Candida and other fungi. In an alternative method, the isolated cells of the various microorganisms are employed with one or mixtures of the above substrates.
