    Abstract: Six novel facultatively anaerobic, Gram-stain-positive, rod-shaped, non-haemolytic bacteria (zg-320 T /zg-336, zg-917 T /zg-910 and zg-913 T /zg-915) isolated from animal tissues and human faeces were found to belong to the genus Corynebacterium based on the phylogenetic analyses of 16S rRNA gene and 262 core genes set. Based on the greatest degree of 16S rRNA similarity, zg-320 T /zg-336 had the highest 16S rRNA gene similarity to Corynebacterium falsenii DSM 44353 T (97.51 %), zg-917 T /zg-910 to Corynebacterium coyleae DSM 44184 T (98.68 %), and zg-913 T /zg-915 to Corynebacterium afermentans subsp. lipophilum CIP 103500 T (98.79 %). The three novel type strains had a relatively high DNA G+C content (61.2–64.4 mol%), low DNA relatedness and ANI values with their respective neighbours: 23.5/72.7 %, 25.0/72.3%and 22.6/73.1 % (zg-320 T vs. Corynebacterium auriscanis CIP 106629 T , Corynebacterium resistens DSM 45100 T and Corynebacterium suicordis DSM 45110 T ); 24.4/82.3% and 23.7/81.3 % (zg-917 T vs. C. coyleae DSM 44184 T and Corynebacterium jeddahense JCB T ); 26.8/83.7% and 27.7/84.4 % (zg-913 T vs. Corynebacterium mucifaciens ATCC 700355 T and C. afermentans subsp. lipophilum CCUG 32105 T ). The three novel species had C 16 : 0 , C 18 : 0 , C 18 : 1  ω 9 c and C 18 : 0 ante/C 18 : 2  ω 6,9 c as the major cellular fatty acids; MK-8(H 2 ) in strain zg-917 T and MK-9(H 2 ) in strains zg-320 T and zg-913 T were found to be the major respiratory quinones. For the three novel species, the detected major polar lipids included diphosphatidylglycerol, phosphatidyl inositol mannoside, phosphatidylglycerol and phosphatidylinositol, the cell-wall peptidoglycan was based on meso -DAP, and the whole-cell sugars mainly included ribose, arabinose and galactose. The three novel species grew optimally at 35–37 °C, 0.5 % (w/v) NaCl and pH 7.0–8.0; notably, they were tolerant of 10.5 % (w/v) NaCl. Based on the results of these comprehensive analyses, three novel species in the genus Corynebacterium are proposed, aptly named Corynebacterium zhongnanshanii sp. nov. (zg-320 T = GDMCC 1.1719 T = JCM 34106 T ), Corynebacterium lujinxingii sp. nov. (zg-917 T = GDMCC 1.1707 T = JCM 34094 T ) and Corynebacterium wankanglinii sp. nov. (zg-913 T = GDMCC 1.1706 T = JCM 34398 T ).

    Abstract: Four strictly anaerobic, Gram-stain-positive, urease-, oxidase- and catalase-negative, rod-shaped strains (zg-886 T /zg-887 and zg-1050 T /zg-1084) were isolated from Marmota himalayana . Comparison analysis of 16S rRNA genes showed that the two strain pairs belong to the family Eggerthellaceae : zg-1050 T and zg-1084 were most closely related to Berryella intestinalis 68-1-3 T (97.2 %), while zg-886 T /zg-887 had the highest similarity to Slackia piriformis YIT 12062 T (91.6 %), followed by Paraeggerthella hongkongensis DSM 16106 T (91.4 %) and Gordonibacter urolithinfaciens DSM 27213 T (91.4 %). Phylogenetic analyses based on 16S rRNA genes and genomes showed that the two strain pairs represent two different lineages within the family Eggerthellaceae . The genomic G+C contents of strains zg-886 T and zg-1050 T were 63.0 and 66.3 mol%, respectively. The values of digital DNA–DNA hybridization, average nucleotide identity, average amino acid identity and the percentage of conserved proteins between the two new type strains and members of the family Eggerthellaceae were lower than the respective thresholds for delineation of a species or genus. In contrast to the absence of any known quinones in strain zg-1050 T , strain zg-886 T contained MK-6 (42.5 %), MMK-6 (25.0 %) and DMMK-6 (32.5 %). The four strains grew optimally at pH 7.0, 37 ºC and 0.5 % NaCl (w/v). According to these polyphasic analyses, two new members within the family Eggerthellaceae are proposed, Xiamenia xianingshaonis gen. nov., sp. nov. (zg-886 T =JCM 34097 T =GDMCC 1.1710 T ) and Berryella wangjianweii sp. nov. (zg-1050 T =GDMCC 1.2426 T =JCM 34748 T ).

    Abstract: Four novel bacterial strains (zg-ZUI122 T /zg-ZUI10 and zg-ZUI227 T /zg-ZUI100) were isolated from the intestinal contents of Marmota himalayana and characterized using a polyphasic approach. Cells were Gram-stain- and catalase-positive, urease- and oxidase-negative. Strains grew optimally at 28–30 °C, pH 7.0, with 0.5 % NaCl (w/v). A comparative analysis of 16S rRNA gene sequences revealed that strain pairs zg-ZUI122 T /zg-ZUI10 and zg-ZUI227 T /zg-ZUI100 belonged to the genus Arthrobacter and were most closely related to Arthrobacter citreus DSM 20133 T , with similarities of 99.6 and 99.5 %, respectively. This was further confirmed by phylogenetic analyses based on the 16S rRNA gene and genome sequences. The digital DNA–DNA hybridization and average nucleotide identity values between the two new type strains (zg-ZUI122 T and zg-ZUI227 T ) and other species in the genus Arthrobacter were 20.0–24.4/77.2–83.4% and 19.9–25.1/77.1–83.4%, all below the thresholds. The major cellular fatty acids detected in the two novel species included iso -C 15 : 0 and anteiso -C 15 : 0 ; the predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. MK-8(H 2 ) (77.3%) was the predominant respiratory quinone detected in strain zg-ZUI122 T , while MK-8(H 2 ) (53.7%) and MK-9(H 2 ) (46.3%) were detected in strain zg-ZUI227 T . The shared cell-wall amino acids detected in the two novel species were alanine, glutamic acid and lysine; the shared whole cell wall sugars consisted of galactose, mannose and ribose. All these analyses concluded that these four strains represent two different novel species in the genus Arthrobacter , for which the names Arthrobacter sunyaminii sp. nov. (zg-ZUI122 T = GDMCC 1.2502 T = KCTC 49677 T ) and Arthrobacter jiangjiafuii sp. nov. (zg-ZUI227 T = GDMCC 1.2500 T = KCTC 49676 T ) are proposed.

    Abstract: Four Gram-stain-positive, facultatively anaerobic, non-motile, non-spore-forming and rod-shaped bacteria (lx-72 T , lx-45, ZJ784 T and ZJ955) were isolated from the respiratory tract or faeces of marmot ( Marmota himalayana ) from the Qinghai–Tibet Plateau in China. Analysis of the 16S rRNA gene sequences showed that all strains belong to the genus Canibacter and are more related to Canibacter oris CCUG 64069 T (95.1–97.4 % similarity) than to the genus Leucobacter . Both strain pairs grew well at pH 6–9 and 15–42°C, and ZJ784 T /ZJ955 could tolerate slightly higher NaCl (0.5–4.5 %, w/v) than lx-72 T /lx-45(0.5–3.5 %). Based on whole-genome sequences, the average nucleotide identity and digital DNA–DNA hybridization values between our four isolates and their closest relative were below the species delineation thresholds of 70 % and 95–96 %. The common major fatty acids ( 〉 10 %) of our four strains were anteiso-C 15 : 0 and anteiso-C 17 : 0 . For both new type strains, MK-8(H 4 ) and MK-9(H 4 ) were the major isoprenoid quinones, and diphosphatidylglycerol and phosphatidylglycerol were the main polar lipids. The genomic DNA G+C content of all strains was 53.9 mol%. Based on results from the genomic comparison, phylogenetic analysis, and physiological and biochemical characteristics, the four isolates represent two novel species in the genus Canibacter , for which the names Canibacter zhuwentaonis sp. nov. (type strain lx-72 T =KCTC 49658 T =GDMCC 1.2569 T ) and Canibacter zhoujuaniae sp. nov. (type strain ZJ784 T =KCTC 49507 T =GDMCC 1.1997 T ) are proposed.
