Phylogenetic analyses indicated conclusively that the strain in question belonged to the genus Alteromonas. Phenotypic tests showed that it could be assigned to the genus Alteromonas although it had a number of distinctive characteristics: it is moderately halophilic, growing best with 7·5–10 % w/v NaCl; it grows at 4 °C and produces H2S; it does not grow with d-cellobiose, d-fructose, d-galactose, d-glucose or lactose as sole sources of carbon and energy; and its fatty-acid profile is typical of Alteromonas but it also contains a large amount of an unusual acid with three double bonds [18 : 3ω6c (6, 9, 12); 5·01 %, w/v]. The major isoprenoid quinone is Q8. The DNA G+C content is 46·3 mol%. The phylogenetic, phenotypic and genetic properties of strain F-32T place it within a novel species, for which the name Alteromonas hispanica sp. nov. is proposed. The type strain is F-32T (=CECT 7067T=LMG 22958T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63809-0
