ABSTRACT
An aerobic, motile, Gram-negative, ice-active substance-producing, rod-shaped psychrophile, designated strain ArB 0140T, was isolated from seawater collected from near a glacier in Kongsfjorden, Svalbard Archipelago, Norway. Phylogenetic analysis using 16S rRNA gene sequences indicated that strain ArB 0140T showed a distinct phyletic line within the genus Moritella. Characteristic chemotaxonomic data [predominant isoprenoid quinone, Q8; major fatty acids, C14 0, C14 1, C16 0, C16 1 and C22 6 (docosahexaenoic acid; DHA)] also corroborated the affiliation of strain ArB 0140T to the genus Moritella. The maximal growth rate of the novel strain was observed at 9 degrees C, with a maximum temperature for growth of 18 degrees C. The genomic DNA G+C content was 46.9 mol%. Based on the data obtained from this polyphasic study, including DNA-DNA relatedness, physiological and biochemical tests and ice-controlling activity, strain ArB 0140T was found to be genetically and phenotypically different from other recognized species of the genus Moritella. Therefore strain ArB 0140T represents a novel species, for which the name Moritella dasanensis sp. nov. is proposed. The type strain is ArB 0140T (=KCTC 10814T=KCCM 42845T=JCM 14759T).
