The obligately halophilic strain was motile by bipolar tufts of flagella and grew optimally at pH 7, and microaerobically or aerobically. Closest neighbours based on 16S rRNA gene nucleotide sequence identity are Marinospirillum celere v1c_Sn-redT (93.31 %) and M. alkaliphilum Z4T (92.10 %) in the family Oceanospirillaceae, class Gammaproteobacteria. PH27AT is distinguished phenotypically from members of the genus Marinospirillum by its hydrolysis of gelatin, the absence of growth in media containing ≤ 1 % (w/v) NaCl and the ranges of temperature (12–40 °C) and pH (5–8) for growth. The major compound ubiquinone Q-9 distinguishes the quinone system of strain PH27AT from those in members of the genus Marinospirillum and other members of the Oceanospirillaceae, in which the major quinone is Q-8. Major polar lipids in PH27AT were phosphatidylethanolamine and phosphatidylglycerol, with moderate amounts of diphosphatidylglycerol and phosphatidylserine. Spermidine and cadaverine dominated the polyamine pattern; large proportions of cadaverine have not been reported in members of the genus Marinospirillum. Genotypic and chemotaxonomic data show that PH27AT does not belong in the genus Marinospirillum or other genera of the family Oceanospirillaceae or the Halomonadaceae. We propose a new genus, Terasakiispira gen. nov., be created to accommodate Terasakiispira papahanaumokuakeensis gen. nov., sp. nov. as the type species, with PH27AT ( = ATCC BAA-995T = DSM 16455T = DSM 23961T) as the type strain., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000438
