Novosphingobium

Abstract

No.vo.sphin.go'bi.um. L. masc. adj. novus new; N.L. neut. n. Sphingobium a bacterial genus; N.L. neut. n. Novosphingobium a new Sphingobium . Proteobacteria / Alphaproteobacteria / Sphingomonadales / Sphingomonadaceae / Novosphingobium The genus Novosphingobium accommodates Gram‐negative, aerobic, nonsporulating, chemoorganotrophic, and rod‐shaped bacteria which are metabolically versatile. The members of this genus have been isolated from a wide range of ecological habitats including soil, coastal and freshwater sediments, deep‐sea environments, groundwater, wastewater treatment plants, activated sludge, contaminated groundwater, bioremediation reactor, hexachlorocyclohexane‐contaminated soil, oil‐contaminated sites, polychlorinated‐dioxin‐contaminated environments, rice seeds, rhizosphere, and plants. Morphologically, the colonies are mostly yellow in color, convex, circular, and smooth. Most of these isolates can be subcultured on R2A agar and may or may not be catalase‐ and oxidase‐positive. Similarly, they may or may not reduce nitrate into nitrite. C 18:1 ω7 c is the major fatty acid present in the membranes of the genus Novosphingobium . The major quinone is ubiquinone‐10, while the major polyamine is spermidine. The major polar lipids observed in Novosphingobium are diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmethylethanolamine, sphingoglycolipid, and phosphatidylcholine. The DNA G + C content ( mol% ): varies between 57.7 and 69.1, lowest in the case of Novosphingobium marinum and highest in the case of Novosphingobium bradum . DNA G + C content (mol%): 57.7–69.1. Type species: Novosphingobium capsulatum (Leifson 1962) Takeuchi et al. 2001.

Novosphingobium aureum sp. nov., a marine bacterium isolated from salt flat sediment

“…Detailed fatty acid compositions of strain YJ-S2-02 T and the related strains are shown in Table S2. According to Table S2, the fatty acid profile of strain YJ-S2-02 T was similar to those of the eight reference strains and also other Novosphingobium species [4, 28, 31, 32], indicating that strain YJ-S2-02 T belongs to the genus Novosphingobium . Although some fatty acid constituents of strain YJ-S2-02 T differed in certain proportions from some references, the largest proportion was same in all reference strains as summed feature 8 (C 18 : 1 ω 6 c /ω7 c ).…”

“…The major respiratory quinone of strain YJ-S2-02 T was Q-10, which is common among the members of the genus Novosphingobium [4]. Strain YJ-S2-02 T exhibited diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipids and two unidentified lipids (Fig.…”

“…[2] as the genus Novosphingobium into the family Sphingomonadaceae , and now the genus was reclassified into the family Erythrobacteraceae [3] on the basis of phylogenetic, phylogenomic and chemotaxonomic analyses. Members of the genus Novosphingobium [4] are characterized as Gram-stain-negative, aerobic, rod-shaped and contain ubiquinone Q-10 as the major respiratory quinone and C 18 : 1 ω 6 c /ω7 c as the major fatty acid. The genomic G+C content of members of the genus Novosphingobium is 60–67 mol%.…”

“…S3). The possession of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid as the major polar lipids are common characteristics of the genus Novosphingobium [4] and also closely related type strains of YJ-S2-02 T [5, 15, 28–30]. The major components of the cellular fatty acids (>10%) of strain YJ-S2-02 T were summed feature 8 (C 18 : 1 ω 6 c /ω7 c ; 20.7%), C 18 : 3 ω 6 c (16.3%) and C 17 : 1 ω 6 c (11.8%).…”

Effects of in situ Remediation With Nanoscale Zero Valence Iron on the Physicochemical Conditions and Bacterial Communities of Groundwater Contaminated With Arsenic

“…Also isolated in culture, Hydrogenophaga (beta-Proteobacteria) is a versatile heterotrophic and chemolithoautotrophic bacterium (with H 2 , CO, and S species, such as thiosulfate, as electron donors) (see above) that was present before and during the entire nZVI treatment. Novosphingobium is broadly distributed in water and soil and can degrade a wide variety of organic pollutants and, in some cases, can also reduce nitrates (Kumar et al, 2020). Flavobacterium includes species isolated from sediments with a high arsenic concentration (Ao et al, 2014), and Leadbetterella is a strictly aerobic bacterial genus (Weon et al, 2005).…”
