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

“…Members of the genus Cohnella are Gram-positive, endospore-forming, aerobic, rod-shaped organisms. At the time of writing, the genus Cohnella contains eight species, Cohnella thermotolerans isolated from a sample of industrial starch production in Sweden, Cohnella hongkongensis from a Chinese patient with neutropenic fever, Cohnella laeviribosi from a volcanic area in Likupang, Indonesia, Cohnella phaseoli from root nodules of Phaseolus coccineus in Spain, Cohnella fontinalis from fresh water in Japan, Cohnella luojiensis from soil of a Euphrates poplar forest in Xinjiang, China, and Cohnella yongneupensis and Cohnella ginsengisoli from wetland and ginseng soils in Korea, respectively (Teng et al, 2003;Kämpfer et al, 2006;Cho et al, 2007;García-Fraile et al, 2008;Shiratori et al, 2010;Cai et al, 2010;Kim et al, 2010). In this paper, we describe the characterization of a novel xylanase-producing bacterium belonging to the genus Cohnella by means of a polyphasic taxonomic study.…”

A xylanolytic bacterium, strain S1-3 T , was isolated from soil collected in Nan province, Thailand. It was characterized taxonomically based on phenotypic characteristics and 16S rRNA gene sequence comparison. The strain was a Gram-stain-positive, facultatively anaerobic, sporeforming, rod-shaped bacterium. It contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-7. Iso-C 16 : 0 (39.5 %) and anteiso-C 15 : 0 (26.8 %) were predominant cellular fatty acids. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol were the major polar lipids. The DNA G+C content was 53.3 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain S1-3 T was affiliated to the genus Cohnella, and was closely related to Cohnella ginsengisoli GR21-5 T and Cohnella thermotolerans CCUG 47242 T with 95.7 and 95.3 % sequence similarity, respectively. Strain S1-3 T could be clearly distinguished from related species of the genus Cohnella by its physiological and biochemical characteristics as well as by its phylogenetic position. Therefore, the strain represents a novel species of the genus Cohnella, for which the name Cohnella thailandensis sp. nov. is proposed. The type strain is S1-3 T (5KCTC 22296 T 5TISTR 1890 T 5PCU 306 T ).

“…The predominant respiratory quinone is MK-7, major fatty acids are iso-C 16 : 0 , anteiso-C 15 : 0 and C 16 : 0 and predominant polar lipids are diphosphatidylglycerol, phsphatidylglycerol and phosphatidylethanolamine (Kämpfer et al, 2006). At the time of writing, it comprises 22 species with validly published names (http://www.bacterio.net/cohnella.html), including C. 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. terrae and C. xylanilytica (Khianngam et al, 2010a), C. thailandensis (Khianngam et al, 2010b), C. panacarvi (Yoon et al, 2007), C. cellulosilytica (Khianngam et al, 2012), C. soli and C. suwonensis (Kim et al, 2011), C. boryungensis (Yoon & Jung, 2012), C. arctica (Jiang et al, 2012), C. ferri (Mayilraj et al, 2013), C. formosensis (Hameed et al, 2013), C. lupini (Flores-Félix et al, 2014) and C. rhizosphaerae (Kämpfer et al, 2014) and the species 'Cohnella plantaginis' has been proposed but its name is not validly published. The aim of this study was to elucidate the taxonomic position of strain D45 T based on phenotypic, chemotaxonomic characterization and 16S rRNA gene sequence analysis.…”

A Gram-stain-positive, rod-shaped, endospore-forming bacterium, strain D45 T , was isolated from soil in Nanjing, China. The organism grew optimally at 30 6C, pH 7.0 and with 0 % NaCl (w/v). The 16S rRNA gene sequence of the isolate showed similarities lower than 97 % with respect to species of the genus Cohnella. The predominant respiratory quinone was MK-7, with MK-6 present as a minor component; anteiso-C 15 : 0 and iso-C 16 : 0 were the major fatty acids. The polar lipids of strain D45 T were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two aminophospholipids, four phospholipids, two glycolipids, one aminolipid and two lipids. The DNA G+C content was 59.5 mol%. DNA-DNA hybridization of the isolate with two reference strains showed relatedness values of 33.4 % with Cohnella ginsengisoli DSM 18997 T and 25.8 % with Cohnella thermotolerans DSM 17683 T . The phylogenetic, chemotaxonomic and phenotypic data supported the classification of strain D45 T as a representative of a novel species of the genus Cohnella, for which the name Cohnella nanjingensis sp. nov. is proposed. The type strain is D45 T (5CCTCC AB 2014067 T 5DSM 28246 T ).
