Taxonomic Characterization

Two Gram-staining-negative, aerobic, rod-shaped bacteria designated strains SR9T and UL070T, were isolated from soil and subjected to taxonomic characterization. Strain SR9T grew at 10–37 °C (optimum 30 °C), at pH 4.0–10.0 (optimum pH 8.0) and in the presence of 0–1 % NaCl (optimum 0 %), and UL070T at 4–33 °C (optimum 30 °C), at pH 4.0–10.0 (optimum pH 7.0) and in the presence of 0–2 % NaCl (optimum 0 %), respectively. Strain UL070T was motile with flagella. Analysis of 16S rRNA gene sequences indicated that the two strains fell into phylogenetic clusters belonging to the genus Pseudomonas . Both strains SR9T and UL070T were mostly related to Pseudomonas campi S1-A32-2T with 99.70 and 99.01% sequence similarities, and the similarity between the two isolates was 98.90 %. The genome-based in silico analyses indicated that each of the strains SR9T and UL070T was clearly separated from other species of Pseudomonas , as the orthologous average nucleotide identity (OrthoANI) and the digital DNA–DNA hybridization (dDDH) values were no higher than 93.09 and 50.03% respectively with any related species, which were clearly below the cutoff for species distinction. The fatty acid profiles of the two strains mainly consisting of unsaturated components, the presence of ubiquinone 9 (Q-9) as the major respiratory quinone, and phosphatidylethanolamine (PE) and diphosphatidylglycerol (DPG) as the diagnostic polar lipids were consistent with their classification into Pseudomonas . The DNA G+C contents of strains SR9T and UL070T were 63.2 mol% and 63.6 mol% respectively. On the basis of both phenotypic and phylogenetic evidences, each of the isolated strains should be classified as a novel species, for which the names Pseudomonas guryensis sp. nov. (type strain=SR9T=KCTC 82228T=JCM 34509T) and Pseudomonas ullengensis sp. nov. (type strain=UL070T=KCTC 82229T=JCM 34510T) are proposed.

Xixi Wetland

A Gram-staining-negative, non-motile, yellow-coloured, rod-shaped bacterium, designated S44T, was isolated from bankside soil of Xixi wetland, located in Zhejiang province, China. Growth of strain S44T was observed at 6–37 °C (optimum, 28 °C) and at pH 6.0–9.0 (optimum, 7.0). No growth occurred in the presence of >2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain S44T represented a member of the genus Flavobacterium , showing the highest sequence similarities to the sequences from Flavobacterium succinicans DSM 4002T (96.9 %), Flavobacterium reichenbachii WB 3.2-61T (96.6 %) and Flavobacterium glycines NCBI 105008T (96.5 %). The G+C content of the genomic DNA was 33.6 mol%. The predominant cellular fatty acids were C15 : 0, iso-C15 : 0, anteiso-C15 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), and the major respiratory quinone was menaquinone 6 (MK-6). The major polar lipids were phosphatidylethanolamine, two unknown aminolipids, two unknown aminophospholipids and four unknown polar lipids. On the basis of the phenotypic and genotypic data, it is proposed that the isolate S44T be classified as representing a novel species of the genus Flavobacterium , for which the name Flavobacterium palustre sp. nov. is proposed. The type strain is S44T ( = CGMCC 1.12811T = NBRC 110389T).

The isolate grew optimally at 20 °C, at pH 7 and with 2 % (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain WP25T belonged to the genus Polaribacter in the family Flavobacteriaceae and the highest sequence similarity was shared with the type strain of Polaribacter sejongensis (98.5 %). The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, C15 : 1ω6c and iso-C15 : 0 3-OH. The main respiratory quinone was menaquinone MK-6. The polar lipids of strain WP25T were phosphatidylethanolamine, two unidentified aminolipids, an unidentified phospholipid and four unidentified lipids. The genomic DNA G+C content was 31.2 mol%. DNA–DNA hybridization experiments indicated <12.6 % genomic relatedness with closely related strains. Based on phylogenetic, phenotypic and genotypic analyses, strain WP25T represents a novel species in the genus Polaribacter , for which the name Polaribacter atrinae sp. nov. is proposed, with the type strain WP25T ( = KACC 17473T = JCM 19202T).

A novel Gram-negative, rod-shaped, motile bacterium, designated strain AK13T, was isolated from a sediment sample collected from mangrove of Namkhana, Sunderbans, West Bengal, India. Strain AK13T was positive for oxidase, DNase and lipase activities and negative for catalase, gelatinase, ornithine decarboxylase, lysine decarboxylase, nitrate reductase, aesculinase and urease activities. The fatty acids were dominated by iso-C11 : 0, iso-C11 : 0 3-OH, iso-C15 : 0, iso-C16 : 0, iso-C17 : 1ω9c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). Strain AK13T contained Q-8 as the major respiratory quinone and diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, two unidentified aminolipids, one unidentified glycolipid and one unidentified lipid as the polar lipids. The DNA G+C content of strain AK13T was 55.2 mol%.

Other members of the family showed sequence similarities <94.4 %. Based on the phenotypic characteristics and phylogenetic inference, strain AK13T is proposed as a member of a novel species of the genus Silanimonas , Silanimonas mangrovi sp. nov.; the type strain is AK13T ( = MTCC 11082T  = DSM 24914T).

Phosphatidylethanolamine, phosphatidylglycerol, an unidentified lipid, two unidentified aminophospholipids and one unidentified aminolipid were detected as major polar lipids. On the basis of this polyphasic taxonomic data, it is concluded that strain MEBiC09566T should be classified as representing a novel species in the genus Kiloniella and the name proposed is Kiloniella spongiae sp. nov. The type strain is MEBiC09566T ( = KCCM 43040T = JCM 19930T). Emended descriptions of the genus Kiloniella Wiese et al. 2009 and Kiloniella laminariae are also given.

The bacterial strain C3T was isolated from permafrost soil in Beijicun, Mohe County, Heilongjiang province, China. Cells of strain C3T were Gram-stain-negative rods, 0.3–0.4 µm in diameter and 1.0–2.6 µm in length. Strain C3T was strictly aerobic. Growth occurred at 15–37 °C but not at 4 or 42 °C, at pH 5.0–9.0 (optimum pH 6.0–7.0) and in the presence of 0–8 g NaCl l−1 (optimum 0–1 g l−1). The analysis of 16S rRNA gene sequences indicated that strain C3T was phylogenetically related to members of the genus Undibacterium , with similarities ranging from 94.7 to 96.5 %. Strain C3T contained ubiquinone 8 as the major respiratory quinone. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), C17 : 0 cyclo, straight-chain C16 : 0, C12 : 0 and C10 : 0, unsaturated C18 : 1ω7c and hydroxylated fatty acids C10 : 0 3-OH and C12 : 0 2-OH. The polar lipids were mainly phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The polyamines were putrescine and 2-hydroxyputrescine. The DNA G+C content was 57.4 mol% (determined from Tm ). Based on these results, it is concluded that strain C3T represents a novel species of the genus Undibacterium , for which the name Undibacterium terreum sp. nov. is proposed, with C3T ( = CGMCC 1.10998T = NBRC 108789T) representing the type strain.
