Abstract

A novel sulfur-oxidizing bacterium designated strain mst6 was isolated from spring water of Masutomi hot spring in Japan. The cells were rod-shaped (1.2–4.0 × 0.5–0.7 μm) and Gram-stain-negative. The G+C content of genomic DNA was around 52.6 mol%. The isolate possessed summed feature 3 (Cω7 and/or Cω6), C and C as major cellular fatty acids. Strain mst6 grew by inorganic carbon fixation and oxidation of inorganic sulfur compounds with oxygen as an electron acceptor. The isolate grew over a temperature range of 5–34 °C, a NaCl concentration range of 0–110 mM and a pH range of 4.6–8.1. Optimum growth occurred at 32 °C, in the absence of NaCl and at pH 5.9–6.2. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain mst6 belongs to the family in the class . The closest cultured relative was TTN with a 16S rRNA gene sequence similarity of 97.0 %. On the basis of the data obtained in this study, strain mst6 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is mst6 ( = NBRC 111150 = DSM 101871). In addition, we propose correcting the name Watanabe, Kojima and Fukui 2015 to corrig. based on Rule 12c, Rule 61 and Appendix 9 of the International Code of Nomenclature of Prokaryotes.
