Iodide Oxidation by <i>Pseudomonas iodooxidans</i>

Abstract

S ummary . Iodide oxidation was catalysed by a haemoprotein peroxidase system produced by the marine bacterium Pseudomonas iodooxidans . The presence of starch was essential for iodide oxidation, and its influence was not attributable to its indicator properties. The polysaccharides glycogen and cellulose, but not pectin, could substitute for starch in the reaction. Dextrin, maltose and glucose were not effective. No explanation can be given at this stage for the requirement of a high polysaccharide for bacterial iodide oxidation.
