title: Photobacterium galatheae sp. nov., a bioactive bacterium isolated from a mussel in the Solomon Sea.
abstract: A novel, Gram-negative marine bacterium, S2753T, was isolated from a mussel of the Solomon Sea, Solomon Islands. Analysis of the 16S rRNA gene sequence and whole genome sequence data placed strain S2753T in the genus Photobacterium with the closest relative being Photobacterium halotolerans DSM 18316T (97.7 % 16S rRNA gene similarity). Strain S2753T was able to grow from 15 to 40 °C and in NaCl concentrations of 0.5 to 9 % (w/v). The predominant fatty acids were 16 : 1ω7c/16 : 1ω6c (27.9 %), 16 : 0 (22.1 %) and 18 : 1ω7c/8 : 1ω6c (21.4 %). The genomic DNA G+C mol content was 49.5 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic differences, strain S2753T is considered to represent a novel species of the genus Photobacterium. Furthermore, whole genome sequence analysis comparing S2753T and type-strains of closely related species of the genus Photobacterium also demonstrated that the strain is genomically distinct enough to be considered a novel species. The name Photobacterium galatheae is proposed and the type-strain is S2753T( = LMG 28894T = DSM 100496T).
