The 16S Rrna Gene

A novel Gram-stain-positive, white-pigmented, non-motile, non-sporulating, catalase- and oxidase-positive, strictly aerobic coccus, designated strain ZXM223T, was isolated from a seawater sample collected from the coast of Qingdao, PR China, during a green algal bloom. It grew at pH 6.0–10.5 and 0–25.0 % (w/v) NaCl, with optimum growth at pH 8.5 and 3.0 % (w/v) NaCl. Growth occurred at 16–42 °C (optimum at 28 °C). The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. Menaquinone 6 (MK-6) was the major respiratory quinone. The polar lipids were phosphatidylglycerol, three unidentified phospholipids and two unknown glycolipids. The peptidoglycan type was l-Lys–Gly5–6. The genomic DNA G+C content was 43.5 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain ZXM223T within the genus Salinicoccus, with sequence similarity of 92.2–97.1 % between ZXM223T and the type strains of this genus. The closest relatives were Salinicoccus kunmingensis YIM Y15T, ‘S. salitudinis’ YIM-C678 and S. alkaliphilus T8T. The DNA–DNA relatedness between strain ZXM223T and S. kunmingensis CGMCC 1.6302T and ‘S. salitudinis’ CGMCC 1.6299 ( = YIM-C678) was 37±3 and 30±2 %, respectively. The phenotypic, chemotaxonomic and phylogenetic characteristics and low DNA–DNA relatedness support the proposal of a novel species of the genus Salinicoccus, Salinicoccus qingdaonensis sp. nov., with the type strain ZXM223T ( = LMG 24855T  = CGMCC 1.8895T).

Major Respiratory Quinone

A thermotolerant, Gram-strain-negative, non-spore-forming and strictly aerobic bacterium, designated GU51T, was isolated from Guhai hot spring in Jimsar county, Xinjiang province, north-west China. Each cell of strain GU51T consisted of an oval body and two symmetrical long (3–6 µm) prosthecae. The strain moved by polar flagellum. Oxidase and catalase were produced. Strain GU51T grew within the ranges of 37–65 °C (optimum 48–50 °C), 0.5–7.5 % (w/v) NaCl (optimum 2–3 %) and pH 6.0–9.0 (optimum pH 7.5). The major respiratory quinone detected was ubiquinone 10 (U-10) and the genomic DNA G+C content was 66.7±0.4 mol%. Major fatty acids (>5 %) were C16 : 0, C18 : 1ω7c and 11-methyl C18 : 1ω7c. The polar lipids consisted of diphosphatidylglycerol, five glycolipids, phosphatidylglycerol and an unknown phospholipid. Phylogenetic analysis showed the closest relatives of strain GU51T were members of the genus Parvularcula with 92.3 % 16S rRNA gene sequence similarity. On the basis of this polyphasic taxonomic characterization, it is suggested that strain GU51T represents a novel species of a new genus in the family ‘ Parvularculaceae ’, for which the name Amphiplicatus metriothermophilus gen. nov., sp. nov. is proposed. The type strain of the type species is GU51T ( = CGMCC 1.12710T = JCM 19779T).

Phototrophic Growth

A bacterial strain, designated AST4T, was isolated from activated sludge. The bacterium did not show significant growth on nutrient broth, but growth was clearly stimulated by addition of supernatant from other bacterial cultures. Culture filtrate of a strain related to the genus Sphingomonas in particular increased the cell yield and growth rate of strain AST4T. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain AST4T is located within the ‘Rhodobacter group’ in the α-3 subclass of Proteobacteria, but is clearly distant from related genera in this group such as Paracoccus, Rhodobacter and Rhodovulum. Strain AST4T is a Gram-negative, non-motile, rod-shaped (0·6–0·8×1·3–2·0 μm) and aerobic bacterium. It was not able to reduce nitrate to nitrite or N2. No phototrophic growth was observed. Optimal growth occurred at 30 °C and pH 6·5–7·5. The dominant cellular fatty acid in the isolate was C18 : 1 cis11. Ubiquinone-10 was the major respiratory quinone. The G+C content was 64·5 mol% (by HPLC). Based on the phylogenetic and phenotypic traits, the name Catellibacterium nectariphilum gen. nov., sp. nov. is proposed for this isolate; the type strain is AST4T (=NBRC 100046T=JCM 11959T=DSM 15620T).

A bacterial strain, designated V2M29T, was isolated from forest soil collected in the Changbai Mountains, Heilongjiang Province, China. Cells of strain V2M29T were Gram-positive, rod-shaped (0.5–0.8 μm in diameter and 1.5–2.0 μm in length), strictly aerobic and non-motile. Colonies produced on R2A agar plates were creamy, smooth, circular and 0.3–0.8 mm in diameter. Strain V2M29T grew at 14–35 °C (optimum, 29 °C), at pH 4.1–10.0 (optimum, pH 7.0–8.0) and in the presence of 0–7.0 % (w/v) NaCl (optimum, 0–2.0 %). Strain V2M29T contained MK-8(H4) as the major respiratory quinone and iso-C15 : 0 (20.9 %), iso-C16 : 0 (18.5 %), C17 : 1 ω8c (16.7 %) and 10-methyl-C17 : 0 (9.2 %) as the major cellular fatty acids. The cell-wall peptidoglycan type was based on meso-2,6-diaminopimelic acid and the acyl type of the muramic acid was acetyl. Diphosphatidylglycerol, phosphatidylinositol and six unknown glycolipids were the major polar lipids. The G+C content of the DNA was 72.0 mol% (T m). 16S rRNA gene sequence analysis indicated that strain V2M29T was phylogenetically related to members of the genus Phycicoccus, with sequence similarities ranging from 96.6–97.8 %. The DNA–DNA relatedness values of strain V2M29T to Phycicoccus dokdonensis DS-8T and Phycicoccus bigeumensis DSM 19264T were 32.5±3.3 % and 29.2±2.3 %, respectively. Based on these results, it is concluded that strain V2M29T represents a novel species of the genus Phycicoccus, for which the name Phycicoccus cremeus sp. nov. is proposed, with V2M29T (=CGMCC 1.6963T =NBRC 104261T) as the type strain.

The 16S Rrna Gene

A rod-shaped, Gram-positive bacterium, strain TNJL143-2T, having N-acyl-d-amino acid amidohydrolase (d-aminoacylase) activity, was isolated from a soil sample from Natori, Japan. It was a non-spore-forming, strictly aerobic bacterium without motility, showing a temperature optimum for growth of 30 °C and a pH optimum for growth of 5–7. The 16S rRNA gene sequence of the strain showed the highest similarities to members of the genus Microbacterium, in particular, Microbacterium aerolatum, Microbacterium foliorum and Microbacterium phyllosphaerae. The chemotaxonomic characteristics, including the compositions of cellular menaquinones, cellular fatty acids and cell-wall amino acids, were consistent with those described for the genus Microbacterium. The G+C content of the genomic DNA was determined as 69·1 mol%. DNA–DNA hybridization studies using type strains of M. aerolatum, M. foliorum and M. phyllosphaerae showed only low levels of relatedness (11–12 %). On the basis of these phenotypic and genotypic results, a novel species, Microbacterium natoriense sp. nov., is proposed, with TNJL143-2T (=JCM 12611T=ATCC BAA-1032T) as the type strain.

A Gram-stain-negative, orange-pigmented and strictly aerobic bacterium, designated strain MJ115T, was isolated from seawater in Pohang, South Korea. Cells were non-motile rods and showed positive reactions for catalase and oxidase tests. Growth of strain MJ115T was observed at 4–35 °C (optimum, 30 °C), pH 6.0–7.0 (optimum, pH 6.5) and in the presence of 0–8.0 % (w/v) NaCl (optimum, 2.0%). Strain MJ115T contained iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 1  ω9c, C17 : 0 2-OH, iso-C16 : 0 3-OH, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) as major cellular fatty acids and menaquinone-6 as the major respiratory quinone. Phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids were detected as major polar lipids. The G+C content of the genomic DNA was 40.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ115T formed a phyletic lineage with Nonlabens marinus S1-08T, Nonlabens agnitus JC2678T and Nonlabens antarcticus AKS 622T within the genus Nonlabens . Strain MJ115T was also most closely related to N. marinus S1-08T, N. agnitus JC2678T and N. antarcticus AKS 622T with 96.5, 96.4 and 96.0 % 16S rRNA sequence similarities, respectively. Here it is proposed that strain MJ115T represents a new species of the genus Nonlabens , for which the name Nonlabens ponticola sp. nov. is proposed. The type strain is MJ115T (=KCTC 72237T=NBRC 113963T). In addition, the comparison of the whole genome sequences and phenotypic features suggested that Nonlabens tegetincola and Nonlabens sediminis belong to the same species. Therefore, it is proposed that N. sediminis is reclassified as a later heterotypic synonym of N. tegetincola .
