N2 - A halophilic, aerobic Gram-negative bacterium, designated strain CVS-6T, was isolated from a sea salt evaporation
pond on the Island of Sal in the Cape Verde Archipelago. Phylogenetic analysis of the 16S rRNA gene sequence
revealed a clear affiliation of the organism with members of the family Idiomarinaceae. Sequence similarities between
CVS-6T and the type strains of the species of the genera Pseudidiomarina and Idiomarina ranged from 93.7% to 96.9%.
The major isoprenoid quinone was ubiquinone 8 (Q-8). The major cellular fatty acids were 15:0 iso (21.8%), 17:0 iso
(12.5%), 17:1 iso o9c (10.7%), and 16:1 o7c (10.6%). The DNA G+C content was 51.6 mol%. The species
represented by strain CVS-6T could be distinguished from the species of the genera Pseudidiomarina and Idiomarina;
however, it was not possible to distinguish both genera from each other using the phenotypic or chemotaxonomic
characteristics examined. Consequently, we propose that the species classified in the genus Pseudidiomarina should be
transferred to the genus Idiomarina. We also propose that, on the basis of physiological and biochemical
characteristics, strain CVS-6T ( ¼ LMG 23123 ¼ CIP 108836) represents a new species which we name Idiomarina
insulisalsae.
