Abstract
A bacterial strain, Gram staining positive, strictly aerobic, rod-shaped, motile bacterium with flagellum and endospore-forming, designated strain YIM B05605T, was isolated from soil sampled in Hamazui hot springs, Tengchong City, Yunnan province, China. Optimum growth for the strain occurred at pH 7.0 and 45 °C. MK-7 was the main menaquinone in the strain YIM B05605T. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. Diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), phosphatidylmonomethylethanolamine (PME), unidentified glycolipid (GL), three unknown aminophospholipids (APLs) and unidentified polarlipid (PL) were part of the polar lipid profile. The major fatty acids were anteiso-C15:0 and iso-C16:0. The DNA G + C content of the type strain was 58.76%. Genome-based phylogenetic analysis confirmed that strain YIM B05605T formed a distinct phylogenetic cluster within the genus Cohnella. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values of strain YIM B05605T with the most related species C. fontinalis YT-1101T were 73.42% and 15.7%. Functional analysis by NR, Swiss-prot, Pfam, eggNOG, GO, KEGG databases revealed that strain YIM B05605T has 13 genes related to the sulfur cycle, 2 genes related to the nitrogen cycle. Based on phylogenomic and phylogenetic analyses coupled with phenotypic and chemotaxonomic characterizations, strain YIM B05605T could be classified as a novel species of the genus Cohnella, for which the name Cohnella caldifontis sp. nov., is proposed. The type strain is YIM B05605T (= CGMCC 1.60052T = KCTC 43462T = NBRC 115921T).

Abstract
Two strains, designated NL03-T5T and NL03-T5-1, were isolated from a soil sample collected from the Nanling National Forests, Guangdong Province, PR China. The two strains were Gram-stain-positive, aerobic, rod-shaped and had lophotrichous flagellation. Strain NL03-T5T could secrete extracellular mucus whereas NL03-T5-1 could not. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the two strains belong to the genus Cohnella, were most closely related to Cohnella lupini LMG 27416T (95.9% and 96.1% similarities), and both showed 94.0% similarity with Cohnella arctica NRRL B-59459T, respectively. The two strains showed 99.8% 16S rRNA gene sequence similarity between them. The draft genome size of strain NL03-T5T was 7.44 Mbp with a DNA G+C content of 49.2 mol%. The average nucleotide identities (ANI) and the digital DNA-DNA hybridization (dDDH) values between NL03-T5T and NL03-T5-1 were 99.98% and 100%, indicating the two strains were of the same species. Additionally, the ANI and dDDH values between NL03-T5T and C. lupini LMG 27416T were 76.1% and 20.4%, respectively. The major cellular fatty acids of strain NL03-T5T included anteiso-C15:0 and iso-C16:0. The major polar lipids and predominant respiratory quinone were diphosphatidylglycerol (DPG) and menaquinone-7 (MK-7). Based on phylogenetic analysis, phenotypic and chemotaxonomic characterization, genomic DNA G+C content, and ANI and dDDH values, strains NL03-T5T and NL03-T5-1 represent novel species in the genus Cohnella, for which the name Cohnella silvisoli is proposed. The type strain is NL03-T5T (=GDMCC 1.2294T = JCM 34999T). Furthermore, comparative genomics revealed that the genus Cohnella had an open pan-genome. The pan-genome of 29 Cohnella strains contained 41,356 gene families, and the number of strain-specific genes ranged from 6 to 1649. The results may explain the good adaptability of the Cohnella strains to different habitats at the genetic level.

Abstract
This study was designed to explore the magnetite in maturation and humification during pig manure (PM) and wolfberry branch fillings (BF) composting. Different proportions of magnetite (T1, 0%; T2, 2.5%; T3, 5%; T4, 7.5%;) were blended with PM for 50 days of composting. The findings indicated magnetite amendment has no influence on the maturity, and the 5% ratio significantly promoted humic acid (HA) formation and fulvic acid (FA) decomposition compared to other treatments. Compared to T1, magnetite addition significantly increased CO2 and CH4 emissions by 106.39%-191.69% and 6.88-13.72 times. The further analysis suggested that magnetite improved Ruminofilibacter activity were significantly positively associated with HA, and C emissions. The further PICRUSt 2 analysis showed membrane transport may enhance environmental information processing by magnetite. Overall, these results demonstrated higher organic matter (OM) degradation and HA formation with an additional increase in microbial activity highlighted advantages of using magnetite during PM composting.

Abstract
A novel strictly aerobic, Gram-stain-positive, rod-shaped, motile, endospore-forming, white-coloured bacterium, designated strain MFER-1T, was isolated from a fermented liquor of wild grasses sampled in the Republic of Korea. The respiratory quinone of strain MFER-1T was menaquinone-7 and its major cellular fatty acids were anteiso-C15 : 0 (55.3 %), iso-C16 : 0 (17.5 %) and C16 : 0 (12.1 %). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four unidentified aminophospholipids and an unidentified phospholipid. The 16S rRNA gene sequence of strain MFER-1T showed similarity of 98.1 % to ‘Cohnella cholangitidis’ 1 605-214T and below 98.0 % sequence similarity to the other
Cohnella
species. The phylogenomic tree indicated that strain MFER-1T formed a reliable cluster with several
Cohnella
species. The estimated genome size of strain MFER-1T was 8.52 Mb. Genomic DNA G+C content was 50.7mol%. The orthologous average nucleotide identity, digital DNA–DNA hybridization and amino acid identity values of strain MFER-1T with the most closely related species ‘Cohnella cholangitidis’ 1 605-214T were 78.7, 23.0 and 79.6 %, respectively. Based on the phenotypic, chemotaxonomic and phylogenetic results, strain MFER-1T should represent a novel species of the genus
Cohnella
, for which the name Cohnella herbarum sp. nov. is proposed, with strain MFER-1T (=KACC 21 257T=NBRC 114 628T) as the type strain.

Abstract
A Gram-positive, aerobic, flagellated, endospore-forming, rod-shaped strain, designated as G13T, was isolated from soil. The results of 16S rRNA gene sequence analysis led to the conclusion that strain G13T was phylogenetically related to Cohnella boryungensis BR29T (97.5 %) and Cohnella phaseoli CECT 7287T (96.9 %) with digital DNA-DNA hybridization values of 21.0 and 21.4 %, and distantly related to Cohnella thermotolerans CCUG 47242T (94.8 %), type species of the genus Cohnella, at 19.0 %. The genome size of strain G13T was 5 387 258 bp, with 51.3 mol% G+C content. The predominant fatty acids were summed feature 9 (iso-C17 : 1 ω9c and/or C16 : 0 10-methyl), anteiso-C17 : 0, iso-C17 : 0 and iso-C15 : 0. The predominant quinone was menaquinone-7 and the major polar lipids were diphosphatidyglycerol, phosphatidylethanolamine, phosphatidylglycerol, lysylphosphatidylglycerol, three aminophospholipids, two phosphoglycolipids, three aminolipids and two unidentified lipids. Based on the data from phenotypic tests and the genotypic differences between strain G13T and its close phylogenetic relatives, strain G13T represents a new species belonging to the genus Cohnella, for which the name Cohnella terricola sp. nov.

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
Cohnella is a highly cellulolytic bacterial genus, which can be found in a variety of habitats. The aim of this study was to assess its presence in the digestive tract of termite species collected in North-eastern Argentina: Nasutitermes aquilinus, N. corniger and Cortaritermes fulviceps. Gut homogenates were incubated with cellulosic substrate for bacterial growth. Bacterial 16S rDNA was partially amplified using new primers for Cohnella spp. and cloned. Sequences obtained showed highest similarity (97.2-99.9%) with those of Cohnella spp. previously reported from diverse environments. Phylogenetic analysis tended to group the clones according to their host species and sampling sites. These results indicate the association of Cohnella-related intestinal symbionts with three common Neotropical termites. Their potential industrial application encourages further research.

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).

Abstract
A novel bacterial strain, CJ22T, was isolated from soil of a ginseng field located in Anseong, Korea. Cells of strain CJ22T were aerobic, Gram-stain-positive, endospore-forming, motile, oxidase- and catalase-positive and rod-shaped. The isolate grew optimally at pH 7 and 30 °C. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain CJ22T belonged to the genus Cohnella, displaying highest sequence similarity of 97.3% with Cohnella panacarvi Gsoil 349T. DNA-DNA relatedness between strain CJ22T and its closest relative was 35.5 % (reciprocal value, 23.8%). The phenotypic features of strain CJ22T also distinguished it from related species of the genus Cohnella. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major isoprenoid quinone was menaquinone MK-7 and the major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, lysyl-phosphatidylglycerol, two unidentified phospholipids and two unidentified aminophospholipids. The predominant cellular fatty acids of strain CJ22T were anteiso-C15 : 0, iso-C16:0 and C16:0. The DNA G+C content was 63.1 mol%. Based on data from this polyphasic taxonomic study, strain CJ22T is considered to represent a novel species of the genus Cohnella, for which the name Cohnella saccharovorans sp. nov. is proposed. The type strain is CJ22T (=KACC 17501T=JCM 19227T).

Abstract
A novel bacterial strain, NKM-5T, was isolated from soil of a lava forest in Nokkome Oreum, Jeju, Republic of Korea. Cells of strain NKM-5T were Gram-stain-positive, motile, endospore-forming, rod-shaped and oxidase- and catalase-positive. Strain NKM-5T contained anteiso-C15 : 0 and iso-C16 : 0 as the major fatty acids; menaquinone-7 (MK-7) as the predominant isoprenoid quinone; diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, lysyl-phosphatidylglycerol, an unidentified phospholipid and three unidentified aminophospholipids as the polar lipids; and meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The DNA G+C content was 48.3 mol%. Phylogenetic analysis, based on 16S rRNA gene sequencing, showed that strain NKM-5T was most closely related to Cohnella lupini RLAHU4BT (96.9 % sequence similarity) and fell into a clade in the genus Cohnella. On the basis of phylogenetic, chemotaxonomic and phenotypic data, strain NKM-5T represents a novel species of the genus Cohnella, for which the name Cohnella collisoli sp. nov. is proposed. The type strain is NKM-5T ( = KCTC 33634T = CECT 8805T).

Abstract
A thermophilic, agar-degrading bacterium, strain FAB2(T), was isolated from sewage sludge compost. According to phylogenetic analysis based on 16S rRNA gene sequences, strain FAB2(T) belonged to the family Paenibacillaceae within the phylum Firmicutes. However, FAB2(T) was different enough at the genus level from closely related species. The percentages of 16S rRNA gene sequence similarity with related organisms were 90.4 % for Thermobacillus xylanilyticus, 91.8 % for Paenibacillus barengoltzii, 89.4 % for Cohnella lupini, 90.1 % for Fontibacillus aquaticus, and 89.0 % for Saccharibacillus sacchari. Morphological and physiological analyses revealed that the strain was motile, rod-shaped, Gram-stain-positive, aerobic and able to form oval endospores in swollen sporangia. Ammonium was required as a nitrogen source while nitrate, nitrite, urea and glutamate were not utilized. Catalase and oxidase activities were weakly positive and positive, respectively. The bacterium grew in the temperature range of 50-65 °C and in media with pH 7.5 to 9.0. Optimal growth occurred at 60 °C and pH 8.0-8.6. Growth was inhibited at pH≤7.0 and NaCl concentrations ≥2.5 % (w/v). In chemotaxonomic characterization, MK-7 was identified as the dominant menaquinone. Major fatty acids were iso-C16 : 0 and C16 : 0. Dominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Phosphatidylcholine was present in a moderate amount. The diamino acid in the cell wall was meso-diaminopimelic acid. The G+C content of the genomic DNA was 49.5 mol% in a nucleic acid study. On the basis of genetic and phenotypic characteristics, strain FAB2(T) ( = NBRC 109510(T) = KCTC 33130(T)) showed characteristics suitable for classification as the type strain of a novel species of a new genus in the family Paenibacillaceae, for which the name Ammoniibacillus agariperforans gen. nov., sp. nov. is proposed.

Abstract
A Gram-staining-positive, aerobic, non-endospore forming organism, isolated as a seed endophyte (colonizing the internal healthy tissue of plant seed) of sweet corn (Zea mays), strain CSE-5610T, was studied for its taxonomic allocation. On the basis of 16S rRNA gene sequence comparisons, strain CSE-5610T was grouped into the genus Cohnella, most closely related to Cohnella ginsengisoli GR21-5T (98.1%) and 'Cohnella plantaginis' YN-83 (97.5%). The 16S rRNA gene sequence similarity to other members of the genus Cohnella was <96.6%. DNA-DNA hybridization of strain CSE-5610T with C. ginsengisoli DSM 18997T and 'C. plantaginis' DSM 25424 was 58% (reciprocal 24%) and 30% (reciprocal 27%), respectively. The fatty acid profile from whole cell hydrolysates supported the allocation of the strain to the genus Cohnella; iso- and anteiso-branched fatty acids were found as major compounds. meso-Diaminopimelic acid was identified as the cell-wall diamino acid. The quinone system consisted predominantly of menaquinone MK-7. The polar lipid profile was composed of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two aminophospholipids, a phospholipid and minor amounts of two polar lipids. In the polyamine pattern, spermidine was the major polyamine. The G+C content of the genomic DNA was 60 mol%. In addition, the results of physiological and biochemical tests also allowed phenotypic differentiation of strain CSE-5610T from the two closely related strains. Hence, CSE-5610T represents a novel species of the genus Cohnella, for which we propose the name Cohnella rhizosphaerae sp. nov., with CSE-5610T (=LMG 28080T=CIP 110695T) as the type strain.

Abstract
A rod-shaped, endospore-forming, Gram-reaction-positive bacterium, designated strain TC22-2bT, was isolated from compost in Tochigi, Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain belonged to a cluster comprising species of the genus
Paenibacillus
and was most closely related to the type strain of
Paenibacillus elgii
(93.4 % similarity). The major cellular fatty acids were C16:0 (25.5 %), iso-C16:0 (23.6 %) and anteiso-C15:0 (21.5 %). The predominant menaquinone was MK-7. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The diamino acid found in the cell wall peptidoglycan was meso-diaminopimelic acid, and the DNA G+C content was 59.1 mol%. The results of physiological and biochemical tests enabled the phenotypic differentiation of strain TC22-2bT from the most closely related species with validly published names. Phylogenetic and phenotypic evidence reveals that strain TC22-2bT represents a novel species of the genus
Paenibacillus
, for which the name
Paenibacillus
thermoaerophilus sp. nov. is proposed. The type strain of the novel species is TC22-2bT ( = DSM 26310T = JCM 18657T).

Abstract
A Gram-positive, spore-forming, aerobic, rod-shaped, xylanolytic bacterium designated strain CC-Alfalfa-35(T) was isolated from the rhizosphere of Medicago sativa L. in Taiwan. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain CC-Alfalfa-35(T) was affiliated to the genus Cohnella. Strain CC-Alfalfa-35(T) shared 95.3 % pairwise 16S rRNA gene sequence similarity to the type strain of the type species of the genus Cohnella (Cohnella thermotolerans DSM 17683(T)) besides showing a similarity of 97.4-93.6 % with other recognized species of the genus Cohnella. The DNA-DNA hybridization value between CC-Alfalfa-35(T) and Cohnella thailandensis KCTC 22296(T) was 37.7 % ± 1.7 % (reciprocal value, 55.7 % ± 3.0 %).

The polar lipid profile constituted diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, lysyl-phosphatidylglycerol, three unidentified phospholipids and three unidentified aminophospholipids. The major respiratory quinone was MK-7 and the DNA G+C content was 58.3 mol%. Strain CC-Alfalfa-35(T) contained meso-diaminopimelic acid as the major diamino acid in the cell-wall peptidoglycan. Based on the polar lipid and fatty acid profiles, which were in line with those of C. thermotolerans DSM 17683(T), coupled with additional distinguishing genotypic, phenotypic and chemotaxonomic features, strain CC-Alfalfa-35(T) is proposed to represent a novel species within the genus Cohnella, for which the name Cohnella formosensis sp. nov. is proposed. The type strain is CC-Alfalfa-35(T) ( = JCM 18405(T) = BCRC 80428(T)).

Abstract
A cellulose-degrading bacterium, strain FCN3-3T, was isolated from buffalo faeces collected in Nakhonnayok province, Thailand. The strain was characterized based on its phenotypic and genotypic characteristics. Strain FCN3-3T was a Gram-positive, aerobic, spore-forming, rod-shaped bacterium. It contained meso-diaminopimelic acid in cell-wall peptidoglycan. The major menaquinone was MK-7. Anteiso-C15 : 0 (52.5 %), iso-C16 : 0 (18.9 %) and C16 : 0 (9.1 %) were the predominant cellular fatty acids, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol were the major phospholipids. The DNA G+C content was 58.0 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain FCN3-3T was affiliated to the genus
Cohnella
and was closely related to
Cohnella phaseoli
GSPC1T,
Cohnella luojiensis
HY-22RT and
Cohnella hongkongensis
HKU3T, with 97.2, 96.8 and 96.3 % sequence similarity, respectively. Strain FCN3-3T could be clearly distinguished from all known species of the genus
Cohnella
by its physiological and biochemical characteristics as well as its phylogenetic position and level of DNA–DNA relatedness. Therefore, the strain represents a novel species of the genus
Cohnella
, for which the name Cohnella cellulosilytica sp. nov. is proposed; the type strain is FCN3-3T ( = KCTC 13645T = TISTR 1996T = PCU 323T).

Abstract
A psychrotolerant Gram-reaction-negative, rod-shaped and orange-pigmented bacterium, designated strain M9-62T, which was motile by means of peritrichous flagella, was isolated from tundra soil sampled near Ny-Ålesund, Svalbard Islands, Norway (78° N). Growth occurred at 4–30 °C (optimum, 25 °C) and pH 5.0–8.0 (optimum, pH 6.0–7.0). Analysis of the 16S rRNA gene sequence of strain M9-62T 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 M9-62T contained anteiso-C15 : 0 (51.1 %), iso-C16 : 0 (7.5 %) and C16 : 0 (6.1 %) as the major cellular fatty acids and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol 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 M9-62T 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 M9-62T ( = CCTCC AB 2010228T = NRRL B-59459T).

Abstract
Two xylan-degrading bacteria, strains MX15-2T and MX21-2T, were isolated from soils collected in Nan province, Thailand. Cells were Gram-reaction-positive, facultatively anaerobic, spore-forming and rod-shaped. They contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-7. iso-C16 : 0 and anteiso-C15 : 0 were the predominant cellular fatty acids. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol were the major polar lipids. The genomic DNA G+C contents of strains MX15-2T and MX21-2T were 63.0 and 65.1 mol%, respectively. Phylogenetic analysis using 16S rRNA gene sequences showed that strains MX15-2T and MX21-2T were affiliated with the genus Cohnella and were closely related to Cohnella thermotolerans CCUG 47242T, with 96.5 and 95.6 % sequence similarity, respectively. The strains could be clearly distinguished from each other and from all known species of the genus Cohnella based on their physiological and biochemical characteristics as well as their phylogenetic positions and levels of DNA–DNA hybridization. Therefore, these two strains represent novel species of the genus Cohnella, for which the names Cohnella xylanilytica sp. nov. (type strain MX15-2T =KCTC 22294T =PCU 309T =TISTR 1891T) and Cohnella terrae sp. nov. (type strain MX21-2T =KCTC 22295T =PCU 310T =TISTR 1892T) are proposed.

Abstract
A xylanolytic bacterium, strain S1-3T, 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, spore-forming, rod-shaped bacterium. It contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-7. Iso-C16 : 0 (39.5 %) and anteiso-C15 : 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 S1-3T was affiliated to the genus Cohnella, and was closely related to Cohnella ginsengisoli GR21-5T and Cohnella thermotolerans CCUG 47242T with 95.7 and 95.3 % sequence similarity, respectively. Strain S1-3T 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 S1-3T (=KCTC 22296T =TISTR 1890T =PCU 306T).
