A Gram-negative, motile, rod-shaped bacterial strain, designated Ad2T, was isolated from a marine sponge, Axinella dissimilis, which was collected from a semi-enclosed marine lake in Ireland. Strain Ad2T grew optimally at 24 °C, at pH 7.0 and in the presence of 3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Ad2T clustered with members of the genus Pseudovibrio , and showed 97.3–98.2 % sequence similarity to the type strains of recognized Pseudovibrio species. DNA–DNA relatedness values between strain Ad2T and the type strains of other Pseudovibrio species were <27 %. The DNA G+C content of strain Ad2T was 50.5 mol%. The major fatty acid was 18 : 1ω7c. Differences in phenotypic properties, together with phylogenetic and DNA–DNA hybridization analyses, indicated that strain Ad2T represented a novel species of the genus Pseudovibrio . The name Pseudovibrio axinellae sp. nov. is proposed, with Ad2T ( = DSM 24994T = NCIMB 14761T) as the type strain.

Strain W-BA2T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of approximately 2.0–3.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain W-BA2T fell within the clade comprising the type strains of species of the genus Sulfitobacter , clustering coherently with the type strains of Sulfitobacter donghicola and Sulfitobacter guttiformis showing sequence similarity values of 98.0–98.1 %. Sequence similarities to the type strains of the other species of the genus Sulfitobacter were 96.0–97.4 %. Strain W-BA2T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The major polar lipids of strain W-BA2T were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The DNA G+C content of strain W-BA2T was 55.0 mol% and its DNA–DNA relatedness values with the type strains of Sulfitobacter donghicola , Sulfitobacter guttiformis and Sulfitobacter mediterraneus were 16–23 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain W-BA2T is separated from other species of the genus Sulfitobacter . On the basis of the data presented, strain W-BA2T is considered to represent a novel species of the genus Sulfitobacter , for which the name Sulfitobacter undariae sp. nov. is proposed. The type strain is W-BA2T ( = KCTC 42200T = NBRC 110523T).

A Gram-negative, non-motile, rod-shaped bacterial strain, designated MA1-6T, was isolated from a sea squirt (Halocynthia roretzi) collected from the South Sea, Korea, and was characterized to determine its taxonomic position. Strain MA1-6T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MA1-6T fell within the clade comprising Ruegeria species and exhibited 95.3–96.5 % similarity to the type strains of recognized Ruegeria species. Strain MA1-6T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid, which is consistent with data for Ruegeria species. The major polar lipids detected in strain MA1-6T and Ruegeria atlantica KCTC 12424T were phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid. The DNA G+C content of strain MA1-6T was 58.6 mol%. Differential phenotypic properties, together with phylogenetic distinctiveness, demonstrated that strain MA1-6T can be distinguished from recognized Ruegeria species. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain MA1-6T is considered to represent a novel species of the genus Ruegeria , for which the name Ruegeria halocynthiae sp. nov. is proposed; the type strain is MA1-6T ( = KCTC 23463T = CCUG 60744T).

The polar lipid profile contained phosphatidylethanolamine, unknown aminolipids, unknown phospholipids and unknown lipids. The total DNA G+C content of strain Z29T was 51.3 mol%. Phenotypic properties and chemotaxonomic data supported the affiliation of strain Z29T with the genus Chitinophaga . The low level of DNA–DNA relatedness (ranging from 14.6 to 29.8 %) to the type strains of other species of the genus Chitinophaga and differential phenotypic properties demonstrated that strain Z29T represents a novel species of the genus Chitinophaga , for which the name Chitinophaga longshanensis sp. nov. is proposed. The type strain is Z29T ( = CCTCC AB 2014066T = LMG 28237T).

Pectinolytic Gram-negative bacteria were isolated from different waterways in the UK and Finland. Three strains (174/2T, 181/2 and Dw054) had the same 16S rRNA gene sequences which shared 99 % sequence similarity to species of the genus Dickeya , and a phylogeny of related genera confirmed attribution to this genus. Fatty acid profile analysis of all three strains found a high proportion of C16 : 1ω7c/C16 : 1ω7c and C16 : 0 fatty acids, and library profile searches found closest matches to Dickeya chrysanthemi . Production of a concatenated phylogeny using six loci, recA, gapA, atpD, gyrB, infB and rpoB, provided a high-resolution phylogeny which placed strains 174/2T and 181/2 as a distinct clade, separated from the other species of the genus Dickeya by a relatively long branch-length. DNA–DNA hybridization analysis with a limited number of reference species also supported the distinctiveness of strains 174/2T and 181/2 within the genus Dickeya . All three strains could be phenotypically distinguished from other species of the genus by fermentation of melibiose and raffinose but not d-arabinose or mannitol. The name Dickeya aquatica sp. nov. is proposed for the new taxon; the type strain is 174/2T ( = NCPPB 4580T = LMG 27354T).
