Strain P-4T was Gram-negative-staining with curved to spiral rod-shaped cells and grew optimally with 3–6 % (w/v) NaCl and at 30 °C. The predominant fatty acids were C18 : 1 ω7c (35.0 %), C16 : 0 (25.0 %), C16 : 1 ω7c (17.9 %), C14 : 0 (6.2 %) and C17 : 0 cyclo (5.2 %). The major respiratory quinone was Q-9 and the genomic DNA G+C content was 61.2±1.0 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain P-4T belonged to the genus Thalassospira of the class Alphaproteobacteria. DNA–DNA hybridization with Thalassospira xiamenensis DSM 17429T showed relatedness of 36.0 %, and lower values were obtained with respect to other Thalassospira species. Based on physiological and biochemical tests and 16S rRNA gene sequence analysis as well as DNA–DNA relatedness, strain P-4T should be placed in the genus Thalassospira within a novel species. The name Thalassospira xianhensis sp. nov. is proposed, with P-4T (=CGMCC 1.6849T =JCM 14850T) as the type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.013201-0
