Cohnella arctica sp. nov., isolated from Arctic tundra soil

Abstract

A psychrotolerant Gram-reaction-negative, rod-shaped and orange-pigmented bacterium, designated strain M9-62 T , which was motile by means of peritrichous flagella, was isolated from tundra soil sampled near Ny-Å lesund, Svalbard Islands, Norway (786 N). Growth occurred at 4-30 6C (optimum, 25 6C) and pH 5.0-8.0 (optimum, pH 6.0-7.0). Analysis of the 16S rRNA gene sequence of strain M9-62 T placed it in the genus Cohnella; sequence similarities of the isolate with type strains of members of related genera ranged from 92.0 to 96.3 %. Strain M9-62 T contained anteiso-C 15 : 0 (51.1 %), iso-C 16 : 0 (7.5 %) and C 16 : 0 (6.1 %) as the major cellular fatty acids and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysylphosphatidylglycerol as the main polar lipids. The major respiratory quinone was MK-7 and the DNA G+C content was 50.3 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain M9-62 T is considered to represent a novel species of the genus Cohnella, for which the name Cohnella arctica sp. nov. is proposed; the type strain is M9-62 T (5CCTCC AB 2010228 T

Cohnella rhizosphaerae sp. nov., isolated from the rhizosphere environment of Zea mays

“…Major fatty acids are iso-C 16 : 0 , anteiso-C 15 : 0 and C 16 : 0 and the predominant polar lipids are diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine (Kämpfer et al, 2006). At present, the genus contains 21 species with validly published names, Cohnella hongkongensis and C. thermotolerans (Kämpfer et al, 2006), C. laeviribosi (Cho et al, 2007), C. phaseoli (García-Fraile et al, 2008), C. damuensis (Luo et al, 2010), C. fontinalis (Shiratori et al, 2010), C. ginsengisoli and C. yongneupensis (Kim et al, 2010), C. luojiensis (Cai et al, 2010), C. thailandensis (Khianngam et al, 2010a), C. terrae and C. xylanilytica (Khianngam et al, 2010b), C. panacarvi (Yoon et al, 2007), C. cellulosilytica (Khianngam et al, 2012), C. soli and C. suwonensis (Kim et al, 2012), C. boryungensis (Yoon & Jung, 2012), C. arctica (Jiang et al, 2012), C. formosensis (Hameed et al, 2013), C. lupini (Flores-Félix et al, 2014) and C. ferri (Mayilraj et al, 2011), as well as 'Cohnella plantaginis' , the name of which has not yet been validly published. Most of the type strains were isolated from different soils (Yoon et al, 2007;Cai et al, 2010;Kim et al, 2010;Kim et al, 2012;Jiang et al, 2012;Yoon & Jung 2012;Khianngam et al, 2010a, b); some were isolated from the rhizosphere (Hameed et al, 2013) or endophytic compartments, root nodules, of plants (FloresFélix et al, 2014;García-Fraile et al, 2008).…”

“…At the time of writing, the genus Cohnella contained 23 species with validly published names (http://www.bacterio.net/cohnella.html; Euzéby, 1997) and two species, ‘ Cohenella plantaginis ’ (Wang et al , 2012) and ‘ Cohenella humi ’ (Nguyen & Lee, 2014) that have been proposed but have not yet been validly published.
