    摘要： The present invention relates to a method for oxidation of iodide which comprises contacting, in an aqueous solution, a copper-containing oxidaze enzyme and a source of ionic iodide(I.sup.-), for a time and under conditions sufficient to permit the conversion of ionic iodide to iodine by the enzyme. The copper-containing enzymes may be, for example, a laccase or a bilirubin oxidaze.
