A taxonomic study was carried out on strain C16B3T, which was isolated from deep seawater of the Pacific Ocean. The bacterium was Gram-stain-negative, oxidase- and catalase- positive and rod-shaped. Growth was observed at salinities of 0–8.0 % and at temperatures of 10–45 °C. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain C16B3T belonged to the genus Solimonas , with the highest sequence similarity to Solimonas terrae KIS83-12T (97.2 %), followed by Solimonas variicoloris MN28T (97.0 %) and the other four species of the genus Solimonas (94.5 –96.8 %). The average nucleotide identity and estimated DNA–DNA hybridization values between strain C16B3T and the type strains of the genus Solimonas were 74.05−79.48 % and 19.5–22.5 %, respectively. The principal fatty acids (>5 %) were summed feature 8 (C18 : 1  ω7c/C18 : 1  ω6c; 20.9 %), iso-C16 : 0 (14.6 %), C16 : 1  ω5c (9.4 %), iso-C12 : 0 (8.4 %), summed feature 2 (C14 : 0 3-OH/iso I-C16 : 1 and C12 : 0 aldehyde; 6.8 %) and C16 : 0 (5.5 %). The G+C content of the chromosomal DNA was 65.37 mol%. The respiratory quinone was determined to be Q-8 (100 %). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, four unidentified aminolipids, six unidentified phospholipids and one unidentified polar lipid. The combined genotypic and phenotypic data show that strain C16B3T represents a novel species within the genus Solimonas , for which the name Solimonas marina sp. nov. is proposed, with the type strain C16B3T (=MCCC 1A04678T=KCTC 52314T).

Two novel Gram-stain-negative, chemoheterotrophic and strictly aerobic bacteria, strains GY2T and SPO729T, were isolated from a tidal flat at Gwangyang Bay in Korea and a marine sponge sample from the Pacific Ocean, respectively. The two strains were halotolerant, catalase- and oxidase-positive, and non-motile rods. Optimum temperature and pH for growth of both strains were observed to be 35 °C and pH 7.0–7.5, but optimum salinity for strain SPO729T [2–3 % (w/v)] was slightly higher than that for strain GY2T (1–2 %). The major cellular fatty acids of both strains were C16 : 0, iso-C15 : 0, iso-C17 : 0, iso-C17 : 1ω9c, C18 : 1ω7c, iso-C11 : 0 and iso-C11 : 0 3-OH. The genomic DNA G+C contents of strains GY2T and SPO729T were 55.1 and 57.9 mol%, respectively, and ubiquinone 8 (Q-8) was detected as the sole respiratory quinone from the two strains. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains GY2T and SPO729T formed tight phyletic lineages with members of the genus Microbulbifer . Strain GY2T was closely related to Microbulbifer okinawensis ABABA23T (98.2 %), strain SPO729T (98.0 %) and Microbulbifer donghaiensis CN85T (97.0 %); strain SPO729T was closely related to M. okinawensis ABABA23T (98.3 %) and M. donghaiensis CN85T (98.2 %). The DNA–DNA relatedness values of strain GY2T with M. okinawensis ABABA23T, strain SPO729T and M. donghaiensis CN85T were 40.0±2.1 %, 13.1±3.9 % and 16.2±5.8 %, respectively, whereas those of strain SPO729T with M. okinawensis ABABA23T and M. donghaiensis CN85T were 48.0±4.0 % and 34.6±9.3 %, respectively. On the basis of phenotypic and molecular features, it is concluded that the two strains GY2T and SPO729T represent two novel species of the genus Microbulbifer , for which the names Microbulbifer gwangyangensis sp. nov. and Microbulbifer pacificus are proposed; the type strains are GY2T ( = KACC 16189T = JCM 17800T) and SPO729T ( = KCCM 42667T = JCM 14507T), respectively.

A Gram-stain-positive, aerobic actinomycete, designated strain YIM M13141T, was isolated from a marine sediment sample from the South China Sea, and its taxonomic position was determined using a polyphasic approach. The strain produced branched substrate mycelium and aerial hyphae, but no diffusible pigments were produced on the media tested. At maturity, substrate mycelium was fragmented and spore chains were formed on aerial hyphae and substrate mycelium. Optimum growth occurred at 28 °C, 1–3 % (w/v) NaCl and pH 7.0. Comparative analysis of the 16S rRNA gene sequence showed that the isolate belongs to the genus Pseudonocardia , showing highest levels of similarity with respect to Pseudonocardia sichuanensis KLBMP 1115T (97.1 %), Pseudonocardia tetrahydrofuranoxydans K1T (97.1 %) and Pseudonocardia kunmingensis YIM 63158T (97.0 %). Whole-organism hydrolysates of the strain contained meso-diaminopimelic acid and the sugars galactose, glucose, mannose and arabinose. The predominant menaquinone was MK-8(H4). The polar lipids detected were diphosphatidylglycerol, phosphatidylcholine, phosphatidylinositol, phosphatidylmethylethanolamine, phosphatidylethanolamine, two unknown phosphoglycolipids and two glycolipids. The major fatty acid was iso-C16 : 0. The G+C content of the genomic DNA was 73.1 mol%. DNA–DNA relatedness with P. tetrahydrofuranoxydans DSM 44239T was 42.8±3.5 % (mean±sd). Based on phylogenetic analysis, phenotypic and genotypic data, it is concluded that the isolate represents a novel species of the genus Pseudonocardia , for which the name Pseudonocardia sediminis sp. nov. is proposed. The type strain is YIM M13141T ( = DSM 45779T = JCM 18540T).

Taxonomic Description

Genome sequence analysis of two strains collected in Canada at the end of the 1970s and deposited in 1998 at the Collection de l’Institut Pasteur has led to the taxonomic description of a novel fish-associated species in the genus Flavobacterium . Both strains, CIP 105534T and CIP 105535, were yellow-pigmented, Gram-stain-negative, non-spore-forming rod-shaped bacteria that exhibited gliding motility. They grew aerobically in a temperature range from 5 to 30 °C with optimal growth at 25 °C on trypticase soy or Reasoner's 2A agar but they did not grow on marine agar. Their major fatty acid profiles were similar, consisting of iso-C15 : 0, C16 : 1 ω7c and/or iso-C15 : 0 2-OH (shown as summed feature 3), C16 : 0 3-OH, iso-C17 : 0 3-OH and C16 : 0. The major polyamine was sym-homospermidine. Phosphatidylethanolamine and, most notably, ornithine-containing lipid OL2 and unidentified aminophospholipid APL1 were major polar lipids. A yellow pigment spot was visible after chromatographic analysis. The predominant respiratory quinone was MK-6. The G+C content of the two genomes was 34 mol% and their size was around 5.8 Mb. Comparison of the 16S rRNA gene sequences with those of the closely related type strains showed high levels of relatedness with Flavobacterium collinsii and Flavobacterium pectinovorum . All average nucleotide identity (ANI) and digital DNA–DNA hybridization values estimated against publicly available Flavobacterium genome assemblies were lower than 90 and 30 %, respectively. Phylogenetic, phenotypic and chemotaxonomic data indicated that the two strains represent a novel species of the genus Flavobacterium , for which the name Flavobacterium bizetiae sp. nov. is proposed. The type strain is CIP 105534T (=LMG 1342T). The unique ability of F. bizetiae to use melibiose as a sole source of carbon could provide a simple phenotypic test to discriminate F. bizetiae from its closest relatives.

The cells were catalase- and oxidase-positive, and motile by means of peritrichous flagella. Growth occurred at NaCl concentrations ranging from 0 to 19 % (optimum, 2–8 %, w/v), from pH 6 to 11 (optimum, 7–8) and at temperatures between 4 and 45 °C (optimum, 33 °C). Phylogenetic analysis based on 16S rRNA, gyrB and rpoD gene sequences and its genome sequence revealed that strain D167-6-1T formed a monophyletic branch within the genus Halomonas and was most closely related to Halomonas saliphila , Halomonas pellis , Halomonas kenyensis , Halomonas daqingensis , Halomonas desiderata and Halomonas lactosivorans (with 98.5, 98.5, 98.4, 98.1, 97.5 and 97.8 % 16S rRNA sequence similarity, respectively). The complete genome size of strain D167-6-1T was 4.49 Mb, with a DNA G+C content of 62.8 mol%. The estimated averagenucleotide identity and DNA–DNA hybridization values between strain D167-6-1T and other closely related species were 77.59–85.35 % and 22.0–30.6 %, respectively. The principal cellular fatty acids (>5 %) were C18 : 1  ω7c, C16 : 0, C19 : 0 cyclo ω8c, summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c) and C17 : 0 cyclo. The polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid, aminophospholipid and two unidentified phospholipids. The predominant respiratory quinones were Q-9 and Q-8. The combined genotypic and phenotypic data show that strain D167-6-1T represents a novel species of the genus Halomonas , for which the name Halomonas diversa sp. nov. is proposed, with the type strain D167-6-1T (=MCCC 1A13316T=KCTC 72441T).

A novel actinobacterium, designated strain BR-34T, was isolated from rhizosphere soil of bamboo (Phyllostachys nigro var. henonis) sampled in Damyang, Korea. The strain was found to have morphological and chemotaxonomic characteristics typical of the genus Catenulispora . The strain contained iso-C16 : 0 as the major fatty acid and MK-9(H4), MK-9(H6) and MK-9(H8) as major isoprenoid quinones. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BR-34T formed a cluster separate from members of the genus Catenulispora and was related most closely to Catenulispora acidiphila ID139908T (97.4 % similarity), Catenulispora rubra Aac-30T (97.3 %), Catenulispora yoronensis TT N02-20T (97.3 %) and Catenulispora subtropica TT 99-48T (97 %). However, the level of DNA–DNA relatedness between strain BR-34T and C. acidiphila ID139908T was only 45.32 %. Based on DNA–DNA relatedness, morphological and phenotypic data, strain BR-34T could be distinguished from the type strains of phylogenetically related species. It is therefore considered to represent a novel species of the genus Catenulispora , for which the name Catenulispora graminis sp. nov. is proposed. The type strain is BR-34T ( = KACC 15070T = NBRC 107755T).
