Sphingobacterium phlebotomi sp. nov., a new member of family Sphingobacteriaceae isolated from sand fly rearing substrate. Int J Syst Evol Microbiol 2021; 71:004809. [PMID: 33956595 PMCID: PMC8289205 DOI: 10.1099/ijsem.0.004809] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Accepted: 04/14/2021] [Indexed: 11/18/2022] Open
Abstract
A Gram-stain-negative, rod-shaped, non-motile, non-spore-forming, aerobic bacterium, designated type strain SSI9T, was isolated from sand fly (Phlebotomus papatasi Scopoli; Diptera: Psychodidae) rearing substrate and subjected to polyphasic taxonomic analysis. Strain SSI9T contained phosphatidylethanolamine as a major polar lipid, MK-7 as the predominant quinone, and C16 : 1ω6c/C16 : 1ω7c, iso-C15 : 0, iso-C17 : 0 3-OH and C16 : 0 as the major cellular fatty acids. Phylogenetic analysis based on 16S rRNA gene sequences revealed that SSI9T represents a member of the genus Sphingobacterium, of the family Sphingobacteriaceae sharing 96.5-88.0 % sequence similarity with other species of the genus Sphingobacterium. The results of multilocus sequence analysis using the concatenated sequences of the housekeeping genes recA, rplC and groL indicated that SSI9T formed a separate branch in the genus Sphingobacterium. The genome of SSI9T is 5 197 142 bp with a DNA G+C content of 41.8 mol% and encodes 4395 predicted coding sequences, 49 tRNAs, and three complete rRNAs and two partial rRNAs. SSI9T could be distinguished from other species of the genus Sphingobacterium with validly published names by several phenotypic, chemotaxonomic and genomic characteristics. On the basis of the results of this polyphasic taxonomic analysis, the bacterial isolate represents a novel species within the genus Sphingobacterium, for which the name Sphingobacterium phlebotomi sp. nov. is proposed. The type strain is SSI9T (=ATCC TSD-210T=LMG 31664T=NRRL B-65603T).

Abstract
A Gram-stain-negative, rod-shaped, aerobic, non-flagellated, chemoheterotrophic bacterium, designated strain IMCC25678T, was isolated from an artificial freshwater reservoir, Chungju Lake, in the Republic of Korea. The 16S rRNA gene sequence analysis indicated that strain IMCC25678T belongs to the genus Sphingobacterium with ≤98.7 % sequence similarities to Sphingobacterium species. Whole genome sequencing of strain IMCC25678T revealed a 3.9 Mbp genome size with a DNA G+C content of 42.2 mol%. The IMCC25678T genome shared ≤89.7 % average nucleotide identity and ≤21.4 % digital DNA-DNA hybridization values with closely related species of the genus Sphingobacterium, indicating that the strain represents a novel species. Summed feature 3 (C16 : 1 ω6c and/or C16 : 1 ω7c), iso-C15 : 0 and iso-C17 : 0 3-OH were found to be the predominant cellular fatty acid constituents in the strain. The major respiratory quinone was MK-7. The major polar lipids were phosphatidylethanolamine, one unidentified phosphoglycolipid, one unidentified sphingolipid and three unidentified polar lipids. Based on the phylogenetic and phenotypic characteristics, strain IMCC25678T was considered to represent a novel species within the genus Sphingobacterium, for which the name Sphingobacterium chungjuense sp. nov. is proposed. The type strain is IMCC25678T (=KACC 19485T=NBRC 113130T).

Abstract
Two Gram-stain-negative, aerobic, non-motile bacterial strains, 36D10-4-7T and 30C10-4-7T, were isolated from bark canker tissue of Populus × euramericana, respectively. 16S rRNA gene sequence analysis revealed that strain 36D10-4-7T shows 98.0 % sequence similarity to Sphingomonas adhaesiva DSM 7418T, and strain 30C10-4-7T shows highest sequence similarity to Sphingobacterium arenae H-12T (95.6 %). Average nucleotide identity analysis indicates that strain 36D10-4-7T is a novel member different from recognized species in the genus Sphingomonas. The main fatty acids and respiratory quinone detected in strain 36D10-4-7T are C18 : 1 ω7c and/or C18 : 1 ω6c and Q-10, respectively. The polar lipids are diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, aminolipid, phosphatidylethanolamine, sphingoglycolipid, two uncharacterized phospholipids and two uncharacterized lipids. For strain 30C10-4-7T, the major fatty acids and menaquinone are iso-C15 : 0, C16 : 1 ω7c and/or C16 : 1 ω6c and iso-C17 : 0 3-OH and MK-7, respectively. The polar lipid profile includes phosphatidylethanolamine, phospholipids, two aminophospholipids and six unidentified lipids. Based on phenotypic and genotypic characteristics, these two strains represent two novel species within the genera Sphingomonas and Sphingobacterium. The name Sphingomonas corticis sp. nov. (type strain 36D10-4-7T=CFCC 13112T=KCTC 52799T) and Sphingobacterium corticibacterium sp. nov. (type strain 30C10-4-7T=CFCC 13069T=KCTC 52797T) are proposed.

Abstract
BACKGROUND Microbial interactions shape the structure and function of microbial communities; microbial co-occurrence networks in specific environments have been widely developed to explore these complex systems, but their interconnection pattern across microbiomes in various environments at the global scale remains unexplored. Here, we have inferred an Earth microbial co-occurrence network from a communal catalog with 23,595 samples and 12,646 exact sequence variants from 14 environments in the Earth Microbiome Project dataset. RESULTS This non-random scale-free Earth microbial co-occurrence network consisted of 8 taxonomy distinct modules linked with different environments, which featured environment specific microbial co-occurrence relationships. Different topological features of subnetworks inferred from datasets trimmed into uniform size indicate distinct co-occurrence patterns in the microbiomes of various environments. The high number of specialist edges highlights that environmental specific co-occurrence relationships are essential features across microbiomes. The microbiomes of various environments were clustered into two groups, which were mainly bridged by the microbiomes of plant and animal surface. Acidobacteria Gp2 and Nisaea were identified as hubs in most of subnetworks. Negative edges proportions ranged from 1.9% in the soil subnetwork to 48.9% the non-saline surface subnetwork, suggesting various environments experience distinct intensities of competition or niche differentiation. Video abstract CONCLUSION: This investigation highlights the interconnection patterns across microbiomes in various environments and emphasizes the importance of understanding co-occurrence feature of microbiomes from a network perspective.

Front Microbiol 2019; 10:2083. [PMID: 31608019 PMCID: PMC6767994 DOI: 10.3389/fmicb.2019.02083] [Citation(s) in RCA: 228] [Impact Index Per Article: 38.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2018] [Accepted: 08/23/2019] [Indexed: 11/25/2022] Open
Abstract
Although considerable progress has been made in recent years regarding the classification of bacteria assigned to the phylum Bacteroidetes, there remains a need to further clarify taxonomic relationships within a diverse assemblage that includes organisms of clinical, piscicultural, and ecological importance. Bacteroidetes classification has proved to be difficult, not least when taxonomic decisions rested heavily on interpretation of poorly resolved 16S rRNA gene trees and a limited number of phenotypic features. Here, draft genome sequences of a greatly enlarged collection of genomes of more than 1,000 Bacteroidetes and outgroup type strains were used to infer phylogenetic trees from genome-scale data using the principles drawn from phylogenetic systematics. The majority of taxa were found to be monophyletic but several orders, families and genera, including taxa proposed long ago such as Bacteroides, Cytophaga, and Flavobacterium but also quite recent taxa, as well as a few species were shown to be in need of revision. According proposals are made for the recognition of new orders, families and genera, as well as the transfer of a variety of species to other genera. In addition, emended descriptions are given for many species mainly involving information on DNA G+C content and (approximate) genome size, both of which can be considered valuable taxonomic markers. We detected many incongruities when comparing the results of the present study with existing classifications, which appear to be caused by insufficiently resolved 16S rRNA gene trees or incomplete taxon sampling. The few significant incongruities found between 16S rRNA gene and whole genome trees underline the pitfalls inherent in phylogenies based upon single gene sequences and the impediment in using ordinary bootstrapping in phylogenomic studies, particularly when combined with too narrow gene selections. While a significant degree of phylogenetic conservation was detected in all phenotypic characters investigated, the overall fit to the tree varied considerably, which is one of the probable causes of misclassifications in the past, much like the use of plesiomorphic character states as diagnostic features.

Abstract
A bacterial strain M05W1-28T was isolated from a well that collected water for irrigation from a deep aquifer at a depth of 400 m. Cells were observed to be rod-shaped, non-motile, aerobic, stained Gram-negative. Optimal growth was obtained at pH 7.0 (range: 6.0-9.0), 28 °C (range: 15-37 °C) and 0 % NaCl (range: 0-1.5 %, w/v) in modified tryptic soy broth (mTSB) without added NaCl and R2A. The cells were found to be positive for catalase and oxidase activities. The major fatty acids (>10 %) were identified as summed feature 3 (C16 : 1 ω7c / C16 : 1 ω6c) and iso-C15 : 0. The major polar lipids were phosphatidylethanolamine, glycolipid, phosphoglycolipids, phospholipids, and unidentified lipids. The major respiratory quinone was menaquinone-7 (MK-7). The genomic G+C content of strain M05W1-28T was 40.7 %. Based on similarities of 16S rRNA gene sequences, strain M05W1-28T was affiliated with the genus Sphingobacterium, exhibiting the highest sequence similarities with S. multivorum LMG 8342T (97.5 %), S. ginsenosidimutans THG07T (97.1 %) and less than 97.0 % to other members of the genus. The average nucleotide identity (ANI) and digital DNA-DNA hybridisation values (dDDH) between M05W1-28T and S. multivorum LMG 8342T were 78.1 and 22.5 %, respectively. Phenotypic characteristics including enzyme activities and carbon source utilisation differentiated the strain from other Sphingobacterium species. The phenotypic, chemotaxonomic and phylogenetic properties suggested that strain M05W1-28T represented a novel species within the genus Sphingobacterium, for which the name Sphingobacterium puteale sp. nov. is proposed. The type strain is M05W1-28T (=CGMCC 1.13711T=KCTC 72027T).

Abstract
The dynamic of a community of 20 bacterial strains isolated from river water was followed in R2 broth and in autoclaved river water medium for 27 days in batch experiments. At an early stage of incubation, a fast-growing specialist strain, Acinetobater sp., dominated the community in both media. Later on, the community composition in both media diverged but was highly reproducible across replicates. In R2, several strains previously reported to degrade multiple simple carbon sources prevailed. In autoclaved river water, the community was more even and became dominated by several strains growing faster or exclusively in that medium. Those strains have been reported in the literature to degrade complex compounds. Their growth rate in the community was 1.5- to 7-fold greater than that observed in monoculture. Furthermore, those strains developed simultaneously in the community. Together, our results suggest the existence of cooperative interactions within the community incubated in autoclaved river water.

Abstract
Three strains of a Gram-stain negative bacterium were isolated from Lake Michigan water. 16S rRNA gene sequence analysis revealed that strain 1131 had sequence similarities to Bosea vaviloviae LMG 28367T, Bosea lathyri LMG 26379T, Bosea lupini LMG 26383T, Bosea eneae CCUG 43111T, Bosea vestrisii CCUG 43114T and Boseamassiliensis CCUG 43117T of 99.8, 99.1, 98.4, 98.4, 98.4 and 98.2 %, respectively. The average nucleotide identity value between strain 1131T and Bosea vaviloviae Vaf-18T was 93.4 % and the DNA relatedness was 38 %. The primary cellular fatty acids of strain 1131T were C16 : 1ω7c and C18 : 1ω7c. The primary polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The major compound in the quinone system was ubiquinone Q-10 and in the polyamine pattern sym-homospermidine was predominant. Additional phenotypic characteristics included growth at 5-35 °C, pH values of pH 5.5-8.0, a salt tolerance range of 0.0-1.2 % (w/v), and production of an unknown water soluble brown pigment. After phenotypic, chemotaxonomic and genomic analyses, this isolate was identified as a novel species for which the name Bosea psychrotolerans is proposed. The type strain is 1131T (NRRL B-65405=LMG 30034).

Strain 5JN-11T grew at salinities of 0-6 % (w/v; optimum 0-2 %), a pH of 7.0-9.0 (pH 7.0-8.0) and temperatures of 20-42 °C (28-30 °C). Based on 16S rRNA gene sequences, the strain was designated a member of the genus Sphingobacterium and the phylogenetic analysis showed that strain 5JN-11T shared the highest similarity to Sphingobacterium gobiense H7T, followed by Sphingobacterium chuzhouense DH-5T and Sphingobacterium arenae H-12T. The unfinished draft genome of strain 5JN-11T was 4.69 Mb. The G+C content of strain 5JN-11T was 42.8 mol%. The average nucleotide identity to S. gobiense H7T was 90.5 %. The respiratory quinone was MK-7, and the major polar lipids were phosphatidylethanolamine and phosphoglycolipid. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0 and iso-C17 : 0 3-OH. On the basis of phenotypic, genotypic and phylogenetic evidence, strain 5JN-11T represents a novel species in the genus Sphingobacterium, for which the name Sphingobacteriumhaloxyli sp. nov. is proposed. The type strain is 5JN-11T (=ACCC 60072T=KCTC 62457T).

Abstract
A Gram-stain-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated YIM X0211T, was isolated from a soil sample of Shiling County, Yunnan Province, south-west China. The new isolate was characterized taxonomically by using a polyphasic approach. The strain grew optimally at 30 °C, at pH 7.0 and with 0-3 % (w/v) NaCl. It was positive for catalase and oxidase but negative for H2S production. Comparative 16S rRNA gene sequence analysis showed that strain YIM X0211T fell within the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii DSM 11724T (97.93 % similarity). The G+C content of the genomic DNA was 41.2 mol%. The predominant respiratory quinone was menaquinone MK-7. The major fatty acids were iso-C15 : 0 2-OH, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c/C16 : 1ω6c). The polar lipids consisted of phosphatidylethanolamine, sphingolipid, and several unknown phospholipids or lipids. The DNA-DNA hybridization value between strain YIM X0211T and S. mizutaii DSM 11724T was 42.3±0.4 %, which is below the 70 % limit for species delineation. These chemotaxonomic data supported the affiliation of strain YIM X0211T to the genus Sphingobacterium. Based on the recorded phenotypic and genotypic characteristics, it is determined that the isolate represents a novel species of the genus Sphingobacterium, for which the name Sphingobacterium soli sp. nov. is proposed. The type strain is YIM X0211T (=KCTC 42696T=CGMCC 1.15966T).

Abstract
A Gram-staining-negative, non-motile, non-spore-forming bacterium designated Y3L14T was isolated from the saline-alkaline soil of a farmland, Inner Mongolia, northern China. Strain Y3L14T could grow at 10-40 °C (optimally at 30 °C), pH 6.0-10.0 (optimally at pH 8.0), and in the presence of 0-6.0 % (w/v) NaCl (optimally with 0-2.0 %). Phylogenetic analysis based on the 16S rRNA gene and DNA gyrase subunit B (gyrB) gene sequences revealed that strain Y3L14T clustered with strains belonging to the genus Sphingobacterium, sharing the highest 16S rRNA gene sequence similarity with Sphingobacterium lactis WCC 4512T (94.99 %). Its major cellular fatty acids contained iso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH and summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c). Menaquinone-7 (MK-7) was the only isoprenoid quinone. Strain Y3L14T contained phosphatidylethanolamine, sphingophospholipid, two unknown phospholipids and three unknown lipids as the major polar lipids. The genomic DNA G+C content of strain Y3L14T was 36.0 mol%. Based on the phenotypic, phylogenetic and genotypic characteristics, strain Y3L14T represents a novel species within the genus Sphingobacterium, for which Sphingobacterium alkalisoli sp. nov. is proposed; the type strain is Y3L14T (=CGMCC 1.15782T=KCTC 52379T).

Abstract
A novel Gram-staining-negative bacterium, designated DH-5T, was isolated from a farmland soil in Chuzhou, Anhui province, China. Cells of strain DH-5T were aerobic, non-motile, non-spore-forming and rod-shaped. The organism grew at 20-37 °C, pH 6.0-9.0 and with 0-5 % NaCl (w/v). The DNA G+C content was 42.8 mol%. The major fatty acids (>5 %) were iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C17 : 0 3-OH and C16 : 0. The respiratory quinone was MK-7, and the major polar lipids were phosphatidylethanolamine and phosphoglycolipid. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DH-5T was a member of the genus Sphingobacterium and shared the highest similarity with Sphingobacterium gobiense H7T (96.0 %), followed by Sphingobacterium arenae H-12T (94.5 %). Strain DH-5T exhibited low DNA-DNA relatedness with S. gobiense H7T (35.1±1.4 %) and S. arenae H-12T (21.4±1.0 %). On the basis of phenotypic, genotypic and phylogenetic evidence, DH-5T is considered to represent a novel species of the genus Sphingobacterium, for which the name Sphingobacterium chuzhouense sp. nov. is proposed. The type strain is DH-5T (=ACCC 19856T=KCTC 42746T).

Abstract
A Gram-stain-negative, strictly aerobic, non-motile, light yellow, short-rod bacterium (designated GJ30-7T) isolated from compost, was characterized using a polyphasic approach, in order to clarify its taxonomic position. Strain GJ30-7T was observed to grow optimally at 30 °C and at pH 7.0 on R2A agar medium. Strain Gsoil GJ30-7T possessed β-glucosidase activity, which was responsible for its ability to transform ginsenosides Rb1 and Rc (the two main active components of ginseng) to ginsenoside F2. Phylogenetic analysis, based on 16S rRNA gene sequence similarities, indicated that GJ30-7T belongs to the genus Sphingobacterium of the family Sphingobacteriaceae and was most closely related to Sphingobacterium yanglingense JCM 30166T (92.6 %), Sphingobacterium psychroaquaticum KACC 18188T (92.6 %), and Sphingobacterium thermophilum KCTC 23708T (92.0 %). The DNA G+C content was 43 mol% and MK-7 was the major isoprenoid quinone. The main polar lipids were phosphatidylethanolamine, one unidentified phospolipid and one unknown polar lipid. In contrast to standard and reference strains, unidentified sphingolipid was also present. The predominant fatty acids of strain GJ30-7T were iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 1ω7c and/or C16 : 1ω6c (summed feature 3) and iso-C17 : 1ω9c and/or C16 : 0 10-methyl (summed feature 9), supporting the affiliation of strain GJ30-7T to the genus Sphingobacterium. However, strain GJ30-7T could be distinguished genotypically and phenotypically from species of the genus Sphingobacterium with validly published names. The novel isolate therefore represents a novel species, for which the name Sphingobacterium jejuense sp. nov. is proposed, with the type strain GJ30-7T (=KACC 18625T=JCM 30948T).

Abstract
A yellow-pigmented strain (JM-1081T) isolated from healthy stem tissue of Zea mays was taxonomically characterized. Cells of the strain were rod-shaped and Gram-stain-negative. Comparative 16S rRNA gene sequence analysis revealed closest relationship to the type strains of Sphingobacterium multivorum (98.1 % similarity), Sphingobacterium mucilaginosum (97.9 %) and Sphingobacterium siyangense (97.8 %). 16S rRNA gene sequence similarities to the type strains of all other Sphingobacterium species were below 97.8 %. Fatty acid analysis of whole-cell hydrolysates of the strain resulted in a pattern typical of the genus Sphingobacterium with iso-C15 : 0 2-OH and/or C16 : 1ω7c, iso-C15 : 0, iso-C17 : 0 3-OH and C16 : 0 and as major compounds. The polyamine pattern contained predominantly sym-homospermidine. The major quinone was menaquinone MK-7 and the only identified lipids in the polar lipid profile were phosphatidylethanolamine and phosphatidylserine. In addition, 15 unidentified lipids were detected in moderate to major amounts. Sphingolipid was detected. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. DNA-DNA hybridizations with two of the closely related type strains, those of S. multivorum and S. siyangense, as well as Sphingobacterium canadense resulted in values below 70 %. In addition to the genotypic differences, differential biochemical and chemotaxonomic properties confirmed that the isolate JM-1081T represents a novel species, for which the name Sphingobacterium zeae sp. nov. is proposed. The type strain is JM-1081T (=LMG 29191T=CCM 8652T).

Abstract
A Gram-stain-negative, non-motile, non-spore-forming bacterium, designated T47T, was isolated from saline soil of the Suaeda corniculata rhizosphere, located on the bank of Wuliangsuhai Lake, Inner Mongolia, northern China. Strain T47T could grow at 10–40 °C (with 30 °C the optimal temperature), pH 6.0–8.0 (optimal pH 6.0) and in the presence of 0–6.0 % (w/v) NaCl [optimal 0–1.0 % (w/v)]. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain T47T formed a stable clade with Sphingobacterium composti 4M24T, Sphingobacterium bambusae IBFC2009T, Sphingobacterium paludis S37T and Sphingobacterium wenxiniae LQY-18T, with the 16S rRNA gene sequence similarities ranging from 91.9–95.4 %. Its major cellular fatty acids contained iso-C15 : 0 (39.9 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c, 23.0 %), C16 : 0 (12.8 %) and iso-C17 : 0 3-OH (9.9 %). MK7 was the major menaquinone. The G+C content of the genomic DNA was 45.5 mol%. Based on the phenotypic, phylogenetic and genotypic characteristics, strain T47T represents a novel species within the genus Sphingobacterium, for which the name Sphingobacterium suaedae sp. nov. is proposed. The type strain is T47T ( = CGMCC 1.15277T = KCTC 42662T).

A Gram-stain-negative, strictly aerobic, motile, short-rod-shaped bacterium, designated strain THG-SQA8T, was isolated from rhizosphere soil of rose in PR China. Strain THG-SQA8T was closely related to members of the genus Sphingobacterium, showed the highest sequence similarities with Sphingobacterium multivorum KACC 14105T (98.0 %) and Sphingobacterium ginsenosidimutans KACC 14526T (97.4 %). DNA–DNA hybridization showed values of 35.2 ± 0.9 % and 8.8 ± 0.3 % DNA reassociation with S. multivorum KACC 14105T and S. ginsenosidimutans KACC 14526T, respectively. Chemotaxonomic data revealed that strain THG-SQA8T possesses menaquinone-7 as the only respiratory quinone, and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0 and C16 : 0 as the major fatty acids. The major polar lipid was phosphatidylethanolamine. The DNA G+C content was 40.7 mol%. These data corroborated the affiliation of strain THG-SQA8T to the genus Sphingobacterium. Thus, the isolate represents a novel species, for which the name Sphingobacterium mucilaginosum sp. nov. is proposed, with THG-SQA8T as the type strain ( = CCTCC AB 2014317T = KCTC 42503T).

Abstract
A Gram-staining-negative, non-motile, catalase- and oxidase-positive strain, designated CCNWSP36-1(T), was isolated from the nodule surface of soybean [Glycine max (L.) Merrill] cultivar Zhonghuang 13. The 16S rRNA gene sequence analysis clearly showed that the isolate represented a member of the genus Sphingobacterium. On the basis of pairwise comparisons of 16S rRNA gene sequences, strain CCNWSP36-1(T) showed 96.8% similarity to Sphingobacterium nematocida CCTCC AB 2010390(T) and less than 95.2% similarity to other members of the genus Sphingobacterium. Growth of strain CCNWSP36-1(T) occurred at 10-40 °C and at pH 5.0-9.0. The NaCl range (w/v) for growth was 0-4%. The predominant isoprenoid quinone was MK-7. The polar lipids were phosphatidylethanolamine and several unidentified polar lipids. Sphingolipid was present. The major fatty acids were iso-C(15:0) and summed feature 3 (comprising C(16:1)ω6c and/or C(16:1)ω7c). The G+C content of the genomic DNA was 41.1 mol%. As the physiological and biochemical characteristics of strain CCNWSP36-1(T) and the type strains of its closest phylogenetic neighbours showed clear differences, a novel species, Sphingobacterium yanglingense, is proposed. The type strain is CCNWSP36-1(T) ( =ACCC 19328(T) =JCM 30166(T)).

Abstract
A mesophilic bacterium appearing as curved rod-shaped cells was isolated from Lake Michigan water. It exhibited highest similarities with
Sediminibacterium ginsengisoli
DCY13T (94.4 %);
Sediminibacterium salmoneum
NJ-44T (93.6 %) and
Hydrotalea flava
CCUG 51397 T (93.1 %) while similarities with other recognized species were <92.0 %. The primary polar lipid was phosphatidylethanolamine, with moderate amounts of two unidentified glycolipids, three unknown polar lipids, one unknown aminophospholipid and one aminolipid. The primary respiratory quinone was MK-7 and sym-homospermidine was the primary polyamine. The major cellular fatty acids were iso-C15 : 1G, iso-C15 : 0, iso-C16 : 0 3-OH and iso-C17 : 0 3-OH, with moderate amounts of iso-C16 : 0. The presence of glycolipids differentiated the novel strains from related genera. The DNA mol% G+C content of the type strain MU-2T was 45.2. Results for other phenotypic and molecular analyses indicated that strain MU-2T is a representative of a novel genus and species for which the name Vibrionimonas magnilacihabitans is proposed. The type strain is MU-2T ( = NRRL B-59231 = DSM 22423).

Abstract
The taxonomic status of a bacterium, strain NCCP-246(T), isolated from rhizosphere of Vigna mungo, was determined using a polyphasic taxonomic approach. The strain NCCP-246(T) can grow at 16-37 °C (optimum 32 °C), at pH ranges of 6-8 (optimum growth occurs at pH 7) and in 0-4 % (w/v) NaCl. Phylogenetic analysis based upon on 16S rRNA gene sequence comparison revealed that strain NCCP-246(T) belonged to genus Sphingobacterium. Strain NCCP-246(T) showed highest similarity to the type strain of Sphingobacterium canadense CR11(T) (97.67 %) and less than 97 % with other species of the genus. The DNA-DNA relatedness value of strain NCCP-246(T) with S. canadense CR11(T) and Sphingobacterium thalpophilum JCM 21153(T) was 55 and 44.4 %, respectively. The chemotaxonomic data revealed the major menaquinone as MK-7 and dominant cellular fatty acids were summed feature 3 [C16:1 ω7c/C16:1 ω6c] (37.07 %), iso-C15:0 (28.03 %), C16:0 (11.85 %), C17:0 cyclo (8.84 %) and C14:0 (2.42 %). The G+C content of the strain was 39.2 mol%. On the basis of DNA-DNA hybridization, phylogenetic analyses, physiological and, biochemical data, strain NCCP-246(T) can be differentiated from the validly named members of genus Sphingobacterium and thus represents as a new species, for which the name, Sphingobacterium pakistanensis sp. nov. is proposed with the type strain NCCP-246(T) (= JCM18974 (T) = KCTC 23914(T)).

Abstract
A novel, Gram-stain-negative, non-motile, non-spore-forming, short rod-shaped, aerobic bacterium designated H-12(T) was isolated from a mixed sandy soil sample collected from Xinjiang, China. Strain H-12(T) grew at 20-37 °C (optimum, 30 °C), pH 7.0-11.0 (optimum, pH 8.5) on TGY medium with 0-5 % NaCl (w/v). 16S rRNA gene sequence analysis indicated that strain H-12(T) shared sequence similarities with Sphingobacterium composti DSM 18850(T) (90.0 %). Strain H-12(T) showed a low level of DNA-DNA relatedness to Sphingobacterium composti DSM 18850(T) (45.5 %). The predominant isoprenoid quinone of strain H-12(T) was MK-7 and the major polar lipid was phosphatidylethanolamine. The predominant cellular fatty acids were C16:1ω7c and/or C16 : 1ω6c, iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 0, C16 : 0 3-OH and iso-C15 : 0 3-OH. DNA G+C content of strain H-12(T) was 44.15 mol%. On the basis of phenotypic, genetic and phylogenetic data, strain H-12(T) is proposed to be a representative of a novel species of the genus Sphingobacterium, for which the name Sphingobacterium arenae sp. nov. is suggested and the type strain is H-12(T) ( = ACCC 05758(T) = KCTC 32294(T)).
