  • Publication number: 20090137012
    Abstract: It has been required to economically produce a large amount of optically active ?-lactone derivatives (for example, pantolactone), which are useful as intermediates in synthesizing useful substances such as pharmaceutical drugs. To achieve this object, it is advantageous to employ an enzymatic technique of asymmetric hydrolysis with a hydrolyzing enzyme lactonase. However, it remains troublesome to prepare the enzyme or utilize a microorganism capable of producing the enzyme. Also, it is difficult to obtain a sufficient and stable enzymatic activity in the case of using recombination techniques. In producing lactonase, which asymmetrically hydrolyzes a ?-lactone derivative such as racemic pantolactone selectively, by a recombination technique, both mature lactonase DNA and signal peptide region DNA are transferred into a host.

    Abstract: A method for obtaining improved yields of isoflavones from spent fermentation beer produced by Actinomycetes grown on leguminous plant materials is demonstrated. This method involves conversion of isoflavone biotransformation products to isoflavone aglycones followed by isolation of the isoflavone aglycones. Formation of the biotransformation products had previously limited the production of isoflavone aglycones in these Actinomycete fermentations.
