Cohnella pontilimi sp. nov., isolated from tidal-flat mud. Arch Microbiol 2021; 203:2445-2451. [PMID: 33666688 DOI: 10.1007/s00203-021-02266-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 02/14/2021] [Accepted: 02/25/2021] [Indexed: 10/22/2022]
Abstract
A Gram-positive, aerobic, endospore-forming, rod-shaped bacterial strain, CAU 1483 T, was isolated from tidal-flat mud in the Republic of Korea. It grew optimally at 30 °C, in a pH 7.0 medium with 2% (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain CAU 1483 T formed a separate clade within Paenibacillaceae together with members of the genus Cohnella. Strain CAU 1483 T exhibited the highest 16S rRNA gene sequence similarity (97.1%) to C. candidum 18JY8-7 T. Whole genome of strain CAU 1483 T was 4.29 Mb in size with a 53.7 mol% G + C content, and included 4046 coding sequences and included 4046 coding sequences, some of which associated with stress response. The average nucleotide identity and digital DNA-DNA hybridization similarity between strain CAU 1483 T and related members of the genus Cohnella were 71.8-74.9% and 22.6-33.9%, respectively. The major respiratory quinone present in this strain was menaquinone-7. Strain CAU 1483 T contained anteiso-C15:0 and iso-C16:0 as the major fatty acids, while its polar lipids consisted of phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, lysyl-phosphatidylglycerol, phosphatidylcholine, three unidentified aminophospholipids, two unidentified lipids and an unidentified phospholipid. Peptidoglycan type was A1γ meso-Dpm. On the basis of taxonomic characterization, strain CAU 1483 T constitutes a novel species, for which the name Cohnella pontilimi sp. nov. is proposed. The type strain of this novel species is CAU 1483 T (= KCTC 43047 T = NBRC 113953 T).

Abstract
A novel Gram-stain-positive, aerobic, motile with peritrichous flagella, rod-shaped bacterium, designated CC-MHH1044T, was isolated from a preserved vegetable sample. A polyphasic taxonomic approach was applied to the isolates in order to clarify its taxonomic position. Growth of the strain CC-MHH1044T occurred at 15-50 °C (optimum, 30 °C), pH 6.0-8.0 (optimum, pH 7.0) and with 0-2.0 % (w/v) NaCl (optimum, 1 %, w/v). The genome of strain CC-MHH1044T consisted of 8.5 Mb and the genomic DNA G+C content was 58.5 mol%. Comparison of the 16S rRNA gene sequences showed that CC-MHH1044T belonged to the genus Cohnella and showed a close relationship with the type strains of Cohnella damuensis (96.2 %) and Cohnella panacarvi (95.9 %), and lower sequence similarity to other species. Average nucleotide identity values calculated from whole-genome sequencing data proved that CC-MHH1044T represents a distinct Cohnella species. The dominant cellular fatty acids (>5 %) included iso-C14 : 0(7.4 %), iso-C15 : 0 (6.4 %), anteiso-C15 : 0(40.3 %), C16 : 0 (6.6 %) and iso-C16 : 0 (27.0 %). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four unidentified aminophospholipids, one unidentified phospholipid and glycolipid. The major polyamine was spermidine. The predominant isoprenoid quinone was menaqinone 7 (MK-7). Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits, together with results of comparative 16S rRNA gene sequence, average nucleotide identity and digital DNA-DNA hybridization analyses, we conclude that strain CC-MHH1044T represents a novel member of the genus Cohnella, for which the name Cohnella fermenti sp. nov. is proposed. The type strain is CC-MHH1044T (=BCRC 81147T=JCM 32834T).

Abstract
A Gram-stain-positive, aerobic, rod-shaped, endospore-forming bacterium, designated strain M2MS4P-1T, was isolated from surface-sterilized bark of Sonneratiaapetala sampled in Guangxi, China. The bacterium was characterized by a polyphasic approach to determine its taxonomic position. 16S rRNA gene sequence comparisons revealed that strain M2MS4P-1T belonged to the genus Cohnella and was most closely to Cohnella luojiensis HY-22RT (98.4 % similarity). The average nucleotide identity value and estimated DDH value between strain M2MS4P-1T and the type strain of C. luojiensis HY-22RT were 79.2 and 20.1 %, respectively. Neither substrate nor aerial mycelia were formed, and no diffusible pigments were observed on the media tested. Strain M2MS4P-1T grew in the pH range 6.0-9.0 (optimum, pH 7.0-8.0), at temperatures between 10-37 °C (30 °C) and in 0-1 % (w/v) NaCl (0 %). The predominant isoprenoid quinone in strain M2MS4P-1T was menaquinone-7. The major fatty acids were anteiso-C15 : 0 and iso-C16 : 0. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, lysyl-phosphatidylglycerol, four unidentified aminophospholipids and two unidentified phospholipids. The DNA G+C content was 51.5 mol%. According to the phylogenetic, phenotypic and chemotaxonomic evidence, strain M2MS4P-1T was clearly distinguishable from other species with validly published names in the genus Cohnella and should therefore be classified as a novel species, for which we suggest the name Cohnellaendophytica sp. nov. The type strain is M2MS4P-1T (=KCTC 43011T=CGMCC 1.13745T).

Abstract
A Gram-stain-positive, rod-shaped, endospore-forming, motile and aerobic bacterial isolate, designated strain K2E09-144T, was obtained from animal faeces that were collected from a karst cave in Guizhou province, China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain K2E09-144T represents a novel member of the genus Cohnella within the family Paenibacillaceae of the phylum Firmicutes. Strain K2E09-144T was phylogenetically closely related to Cohnella nanjingensis D45T (16S rRNA gene sequence similarity 97.0 %). The major cellular fatty acids were anteiso-C15:0, iso-C16:0 and C16 : 0. The major isoprenoid quinone was menaqinone 7 (MK-7). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one unidentified phospholipid, four unidentified aminophospholipids, one glycolipid and one unidentified lipid. The isomer type of diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The genome of strain K2E09-144T comprised 6.43 Mb, and encoded 6029 genes in total. The DNA G+C content of the genomic DNA was 53.3 mol%. Based on its phylogenetic, phenotypic and chemotaxonomic characteristics, strain K2E09-144T is considered to represent a novel species of the genus Cohnella, for which the name Cohnella faecalis sp. nov. is proposed. The type strain is K2E09-144T (=CGMCC 1.13587T=NBRC 113454T).

Abstract
A facultative anaerobic, rod-shaped, endospore-forming and non-motile bacterium was isolated from permafrost sediment cores in the Kolyma lowland, Siberia, Russia. The permafrost isolate clustered with members of the genus Cohnella on the basis of 16S rRNA gene sequence analysis and showed the highest sequence similarity to Cohnella saccharovorans CJ22T (96.3 %), followed by Cohnella cellulosilytica FCN3-3T (96.0 %) and Cohnella panacarvi KCTC 13060T (96.0 %). The chemotaxonomic characteristics (quinone system, cellular fatty acids and polar lipid profile) of strain 20.16T were consistent with members of the genus Cohnella. The peptidoglycan diaminoacids included meso-diaminopimelic acid and a small amount of ll-diaminopimelic acid. The molar ratio and composition of major amino acids (meso-diaminopimelic acid, alanine, and glutamic acid) correspond to the peptydoglycan type A1γ. The estimated genome size of strain 20.16T is 4.34 Mb (lower than those in other Cohnella species). The genome has a G+C content of 50.5 mol% and encodes 4843 predicted genes, of these 4740 are protein-coding ones. The results of chemotaxonomic, physiological and biochemical characterization allowed clear differentiation of strain 20.16T from the closest Cohnella species. Based on data provided, a new species Cohnella kolymensis sp. nov. is proposed, with 20.16T (=VKM B-2846T=DSM 104983T) as the type strain.

Abstract
A Gram-stain-positive, facultatively aerobic and endospore-forming bacterium, designated strain Pch-40T, was isolated from a freshwater green alga, Paulinella chromatophora. Cells were motile rods with a monotrichous polar flagellum showing catalase- and oxidase-positive reactions. Strain Pch-40T grew at 20-50 °C (optimum, 37-40 °C), at pH 5.0-11.0 (optimum, pH 7.0) and in the presence of 0-4.0 % (w/v) NaCl (optimum, 0 %). Menaquinone-7 was detected as the sole isoprenoid quinone. The genomic DNA G+C content of strain Pch-40T was 55.6 mol%. The major cellular fatty acids of strain Pch-40T were C16 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Pch-40T clearly belonged to the genus Cohnella of the family Paenibacillaceae. Strain Pch-40T was most closely related to Cohnella rhizosphaerae CSE-5610T with a 96.1 % 16S rRNA gene sequence similarity. The phenotypic and chemotaxonomic features and the phylogenetic inference clearly suggested that strain Pch-40T represents a novel species of the genus Cohnella, for which the name Cohnellaalgarum sp. nov. is proposed. The type strain is strain Pch-40T (=KACC 19279T=JCM 32033T).

Abstract
A Gram-stain-positive, aerobic, non-endospore-forming organism, isolated from a coolant lubricant solution was studied for its taxonomic position. On the basis of 16S rRNA gene sequence similarity comparisons, strain KSS-154-50T was grouped into the genus Cohnella, most closely related to Cohnella formosensisCC-ALFALFA-35T (97.3 % 16S rRNA gene sequence similarity), Cohnella rhizosphaerae CSE-5610T (97.1 %) and Cohnella nanjingensis D45T (97.0 %); the 16S rRNA gene sequence similarity to other species of the genus Cohnella was <97.0 %. The fatty acid profile from whole cell hydrolysates was very similar to those reported for other species of the genus Cohnella and supported the allocation to the genus Cohnella. In the fatty acid profiles, iso- and anteiso-branched fatty acids were found as major compounds. The quinone system consisted predominantly of menaquinone MK-7. The polar lipid profile contained the major lipids diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The major polyamine is spermidine. The results of physiological and biochemical characterization allowed in addition a phenotypic differentiation of strain KSS-154-50T from the three most closely related species. Hence, strain KSS-154-50T represents a novel species of the genus Cohnella, for which the name Cohnella lubricantis sp. nov. is proposed. The type strain is KSS-154-50T (=LMG 29763T=CCM 8707T).
