A 16S rRNA gene sequence analysis indicated that the isolate was affiliated with the genus Thalassospira in the Alphaproteobacteria; the sequence was found to be most similar to those of Thalassospira profundimaris WP0211T (99.8 %), Thalassospira xiamenensis M-5T (98.2 %) and Thalassospira lucentensis DSM 14000T (98.1 %). However, the levels of DNA–DNA relatedness between strain 1-1BT and these type strains were 50.7±17.2, 35.7±17.8 and 32.0±21.1 %, respectively. In addition, strain 1-1BT was found to be distinct from the other described species of the genus Thalassospira in terms of some taxonomically important traits, including DNA G+C content, optimum growth temperature, salinity tolerance, utilization of carbon sources and fatty acid composition. Furthermore, strain 1-1BT and T. profundimaris were also different with regard to motility and denitrification capacities. On the basis of physiological and DNA–DNA hybridization data, strain 1-1BT represents a novel species within the genus Thalassospira, for which the name Thalassospira tepidiphila sp. nov. is proposed. The type strain is 1-1BT (=JCM 14578T =DSM 18888T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65476-0
