مستخلص:	Two novel Gram-strain-negative and rod-shaped bacteria, designated strain G1 ^T and G2 ^T , were isolated from sediment samples collected from the coast of Xiamen, PR China. The cells were motile by a single polar flagellum. Growth of strain G1 ^T occurred at 10-40 °C (optimum, 30 °C), at pH 6.0-9.0 (optimum, pH 7.5) and with 5-1530 mM NaCl (optimum, 510 mM), while the temperature, pH and NaCl concentration ranges for G2 ^T were 4-45 °C (optimum, 28 °C), pH 5.5-8.0 (optimum, pH 6.5) and 85-1530 mM NaCl (optimum, 340 mM). The two isolates were obligate chemolithoautotrophs capable of using thiosulfate, sulfide, elemental sulphur or tetrathionate as an energy source. Strain G1 ^T used molecular oxygen or nitrite as an electron acceptor, while strain G2 ^T used molecular oxygen as the sole electron acceptor. The dominant fatty acids of G1 ^T and G2 ^T were summed feature 3 (C 16:1 ω7 c and/or C 16:1 ω6 c ), C 16 : 0 and summed feature 8 (C 18:1 ω7 c and/or C 18:1 ω6 c ). The DNA G+C content of G1 ^T and G2 ^T were 45.1 and 48.3 mol%, respectively. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain G1 ^T and G2 ^T were members of the genus Thiomicrorhabdus , and most closely related to Thiomicrorhabdus hydrogeniphila MAS2 ^T (96.0 %) and Thiomicrorhabdus indica 13-15A ^T (95.4 %), respectively. The 16S rRNA gene sequence similarity between strains G1 ^T and G2 ^T was 95.8 %. Based on the phylogenetic, genomic and phenotypic data presented here, the isolate strains represent novel species of the genus Thiomicrorhabdus , for which the names Thiomicrorhabdus sediminis sp. nov. (type strain G1 ^T =MCCC 1A14511 ^T =KCTC 15841 ^T ) and Thiomicrorhabdus xiamenensis sp. nov. (type strain G2 ^T =MCCC 1A14512 ^T =KCTC 15842 ^T ) are proposed.
