Comamonas thiooxidans (strain S23(T)) capable of oxidizing thiosulfate under a mixotrophic growth condition was isolated from a sulfur spring. DNA-DNA homology study showed 55% similarity with Comamonas testosteroni KCTC2990(T) and 52% with Comamonas composti LMG24008(T), the nearest phylogenetic relative (16S rRNA sequence similarity <97%). Comparative genomic fingerprinting by using ERIC and Rep-PCR further delineated species identity of the strain S23(T) for which Comamonas thiooxidans sp. nov. is proposed. In addition, thiosulfate oxidation potential of the strain S23(T) was compared with Comamonas testosteroni and Comamonas composti.
从硫磺泉中分离到一株能够在混合营养生长条件下氧化硫代硫酸盐的产碱菌（Comamonas thiooxidans）（S23(T) 株）。DNA-DNA 同源性研究表明，它与 Comamonas testosteroni KCTC2990(T) 的相似度为 55%，与 Comamonas composti LMG24008(T) 的相似度为 52%，是最近的亲缘关系（16S rRNA 序列相似度<97%）。用 ERIC 和 Rep-PCR 进行比较基因组指纹图谱分析进一步确定了 S23(T) 株的种属身份，建议将其命名为 Comamonas thiooxidans sp. nov.。此外，还比较了 S23(T) 株、Comamonas testosteroni 和 Comamonas composti 的硫代硫酸盐氧化潜力。
