Ferrimonas sediminum sp. nov., isolated from coastal sediment of an amphioxus breeding zone

Abstract

A Gram-stain-negative, facultatively anaerobic rod with a polar flagellum, designated strain JYr13T, was isolated from coastal sediment of an amphioxus breeding zone located in Qingdao, China. The isolate utilized Fe(III) oxyhydroxide, Fe(III) citrate, SeO3 2– and SeO4 2– as electron acceptors. Strain JYr13T grew optimally at 25–28 °C, pH 7.0–8.0 and in presence of 3 % (w/v) NaCl. Strain JYr13T contained menaquinone-7 and ubiquinones Q-7 and Q-8 as the predominant isoprenoid quinones, and C18 : 1ω9c, iso-C15 : 0, C17 : 1ω8c and C16 : 0 as the major fatty acids. The DNA G+C content of strain JYr13T was 59 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the closest phylogenetic neighbour of strain JYr13T was Ferrimonas kyonanensis DSM 18153T (96.0 % 16S rRNA gene sequence similarity). Based on the phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain JYr13T is considered to represent a novel species of the genus Ferrimonas , for which the name Ferrimonas sediminum sp. nov. is proposed. The type strain is JYr13T ( = DSM 23317T = LMG 25564T).
