Characterization of Martelella soudanensis sp. nov., Isolated from a Mine Sediment.

ABSTRACT: Gram-stain-negative, strictly aerobic, non-spore-forming, non-motile, and rod-shaped bacterial strains, designated NC18^T and NC20, were isolated from the sediment near-vertical borehole effluent originating 714 m below the subsurface located in the Soudan Iron Mine in Minnesota, USA. The 16S rRNA gene sequence showed that strains NC18^T and NC20 grouped with members of the genus Martelella, including M. mediterranea DSM 17316^T and M. limonii YC7034^T. The genome sizes and G + C content of both NC18^T and NC20 were 6.1 Mb and 61.8 mol%, respectively. Average nucleotide identity (ANI), the average amino acid identity (AAI), and digital DNA-DNA hybridization (dDDH) values were below the species delineation threshold. Pan
