A taxonomic study was carried out on a novel bacterium, designated strain ck-I2-15T, which was isolated from deep-sea sediment collected from the South-west Indian Ocean Ridge. Cells of strain ck-I2-15T were Gram-reaction-negative, rod-shaped, non-motile, moderately halophilic and capable of denitrification. Growth was observed with 0–9 % (w/v) NaCl and at temperatures of 10–37 °C. The novel strain was unable to degrade gelatin. The dominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0). The major respiratory quinone was MK6 and the polar lipid profile comprised phosphatidylethanolamine, one unidentified phospholipid, two unidentified aminolipids, one unidentified glycolipid and four other unidentified lipids. The G+C content of the genomic DNA was 38 mol%. 16S rRNA gene sequence comparison indicated that strain ck-I2-15T was most closely related to Galbibacter mesophilus Mok-17T (92.9 % sequence similarity), followed by ‘Joostella atrarenae’ M1-2 (92.8 %), Joostella marina En5T (92.7 %) and Zhouia amylolytica HN-171T (91.6 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain ck-I2-15T formed a clade with the genus Galbibacter , within the family Flavobacteriaceae . Several phenotypic properties allowed strain ck-I2-15T to be distinguished from its closest phylogenetic relatives. On the basis of the phenotypic and phylogenetic data, strain ck-I2-15T represents a novel species of the genus Galbibacter , for which the name Galbibacter marinus is proposed. The type strain is ck-I2-15T ( = CCTCC AB 209062T = LMG 25228T = MCCC 1A03044T).

A novel marine actinomycete, designated strain KJ-029T, was isolated from a marine sediment sample (water depth of 226 m) in Kagoshima, Japan. 16S rRNA gene sequence analysis revealed that the new isolate was most closely related to Micromonospora craniellae LHW 63014T (99.3 % similarity). Phylogenetic analyses of the genus Micromonospora based on 16S rRNA gene sequences showed that strain KJ-029T was clustered with Micromonospora craniellae LHW 63014T and Micromonospora endophytica 202201T. However, digital DNA–DNA hybridization analyses presented low levels of relatedness in the range of 24.8–32.9 % between strain KJ-029T and the above closely related strains. The novel strain contained meso-diaminopimelic acid and 3-OH-diaminopimelic acid, d-glutamic acid, glycine and d-alanine in the cell-wall peptidoglycan. The acyl type of the peptidoglycan was glycolyl and mycolic acids were absent. The major menaquinone was MK-9(H4). The whole-cell sugars consisted of glucose, mannose, xylose and ribose. Phosphatidylethanolamine was detected as the major phospholipid and corresponded to phospholipid type II. The predominant cellular fatty acid was iso-C16 : 0. The DNA G+C content of the genomic DNA was 71.5 mol%. Based on the present polyphasic study, strain KJ-029T represents a novel species of the genus Micromonospora , for which the name Micromonospora pelagivivens sp. nov. is proposed. The type strain is KJ-029T (=NBRC 113519T=TBRC 9233T).

A Gram-stain-negative, rod-shaped and non-motile strain, designated PAMC 27266T, was isolated from deep-sea sediment of the Arctic Ocean. Analysis of the 16S rRNA gene sequence of strain PAMC 27266T showed closest affiliation with the genus Sediminicola . Phylogenetic analyses revealed that strain PAMC 27266T formed a robust clade with Sediminicola luteus CNI-3T, with which it shared 98.9 % 16S rRNA gene sequence similarity. Genomic relatedness analyses based on the average nucleotide identity and genome-to-genome distance showed that strain PAMC 27266T is clearly distinguished from S. luteus . Cells of strain PAMC 27266T grew optimally at 15 °C and pH 6.5–7.5 in the presence of 3.5 % (w/v) sea salts. The major polar lipids were phosphatidylethanolamine, two unidentified aminophospholipids and two unidentified lipids. The only respiratory quinone was menaquinone-6. The major cellular fatty acids (>10 %) were C16 : 1ω6c and/or C16 : 1ω7c and C15 : 0. The genomic DNA G+C content was 37.9 mol%. Based on the phylogenetic, genomic, chemotaxonomic and phenotypic data presented, we propose strain PAMC 27266T ( = KCCM 43038T = JCM 19894T) as the type strain of a novel species, with the name Sediminicola arcticus sp. nov.

Chakrabartia godavariana PRB40T was compared with Aestuariisphingobium litorale SYSU M10002T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of C. godavariana PRB40T had high similarity (99.8 %) to that of A. litorale SYSU M10002T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Chakrabartia . A draft genomic comparison between the two strains revealed an average nucleotide identity of 97.3 % and a digital DNA–DNA hybridization estimate of 79.5±2.9 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking differences in metabolic, physiological or chemotaxonomic features. Therefore, we propose that Aestuariisphingobium litorale is a later heterotypic synonym of Chakrabartia godavariana .
