Abstract

Two strains of iodine-producing bacteria were isolated from marine samples. 16S rRNA gene sequences indicated the strains were most closely related to Roseovarius tolerans, and phylogenetic analysis indicated both belong to the same genus. 5 mM iodide inhibited the growth of strain 2S5-2 almost completely, and of strain S6V slightly. Both strains produced free iodine and organic iodine from iodide. CH₂I₂, CHI₃ and CH ₂ClI were the main organic iodines produced by strain 2S5-2, and CHI₃ and CH₂I₂ by strain S6V. Experiments using cells and spent media suggested that the organic iodines were produced from the compounds released or contained in the media and cells were necessary for the considerable production of CH₂I₂ and CH ₂ClI, though CHI₃ was produced by spent media with H ₂O₂ or free iodine.
