  • Publication number: 20140242646
    Abstract: The present invention relates to a method comprising the steps a) providing a primary alcohol of the formula HO—(CH2)x—R1, wherein R1 is selected from the group consisting of —OH, —SH, —NH2 and —COOR2, x is at least 3 and R2 is selected from the group consisting of H, alkyl and aryl, b) oxidizing the primary alcohol by contacting it with an NAD(P)+-dependent alcohol dehydrogenase, and c) contacting the oxidation product of step a) with a transaminase, wherein the NAD(P)+-alcohol dehydrogenase and/or the transaminase is a recombinant or isolated enzyme, to a whole cell catalyst for carrying out the method, and to the use of such a whole cell catalyst for oxidizing a primary alcohol.
