Analysis of the 16S rRNA gene sequence of strain DPN7T revealed 98.5 % similarity to that of Tetrathiobacter kashmirensis LMG 22695T. Values for sequence similarity to members of the genera Alcaligenes, Castellaniella and Taylorella, the nearest neighbours of the genus Tetrathiobacter, were about 95 % or less. The DNA G+C content of strain DPN7T was 55.1 mol%. The level of DNA–DNA hybridization between strain DPN7T and T. kashmirensis LMG 22695T was 41 %, whereas it was much lower between strain DPN7T and Alcaligenes faecalis LMG 1229T (7 %) or Castellaniella defragrans LMG 18538T (5 %). This genotypic divergence was supported by differences in biochemical and chemotaxonomic characteristics. For this reason, and because of the differences in the protein and fatty acid profiles, strain DPN7T should be classified within a novel species of Tetrathiobacter, for which the name Tetrathiobacter mimigardefordensis sp. nov. is proposed. The type strain is strain DPN7T (=DSM 17166T=LMG 22922T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.64126-0
