从海水样品中分离到两株产碘细菌。16 S rRNA基因序列分析表明，该菌株与耐玫瑰卵巢菌（Roseovarius tolerans）亲缘关系最近，系统发育分析表明二者属于同一属。5 mM碘几乎完全抑制菌株2S 5 -2的生长，而对菌株S6 V的生长则有轻微抑制。两株菌均能从碘化物中产生游离碘和有机碘。菌株2S 5 -2产生的有机碘主要为CH_2 I_2、CH_3和CH_2Cl_1，菌株S6 V产生的有机碘主要为CH_3和CH_2 I_2。使用细胞和废培养基的实验表明，有机碘是由培养基中释放或含有的化合物产生的，细胞是大量产生CH 2 I 2和CH 2 Cl I所必需的，尽管CH 3是由含有H2 O2或游离碘的废培养基产生的。(C)2003年，欧洲微生物学会联合会。Elsevier B.

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 CH2ClI 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 CH2ClI, though CHI3 was produced by spent media with H2O2 or free iodine.
