    Abstract: A method for preparing ortho-dihydroxyisoflavones having high antioxidative and skin-whitening effects through the biotransformation system is provided to improve the preparation yield of ortho-dihydroxyisoflavones by using microorganisms. The ortho-dihydroxyisoflavones including 7,8,4݆-trihydroxyisoflavone, 7,6,4݆-trihydroxyisoflavone, 7,3݆,4݆-trihydroxyisoflavone and 7,5,3݆,4݆-tetrahydroxyisoflavone are prepared by biotransforming daidzein and genistein with a microorganism derived from Actinomyces selected from Streptomyces evermitilis, Nocardia farcinica and Streptomyces lincolnesis through site specific hydroxylation at 3݆ site in a batch reactor to which oxygen is supplied.
