Three Gram-stain-positive, catalase-negative, α-haemolytic, chain-forming and coccus-shaped microorganisms (strains Z15T, Z1 and Z2) were isolated from feces of Tibetan antelopes collected from the Qinghai–Tibet plateau, PR China. The results of 16S rRNA gene sequence studies indicated that Z15T shared 94.5, 93.1 and 92.2 % similarity with Streptococcus pantholopis DSM 102135T, Streptococcus ursoris NUM 1615T and Streptococcus dentapri NUM 1529T, respectively. rpoB and groEL-based sequence analysis of our three novel isolates revealed interspecies divergence of 16.7 and 14.3 % from Streptococcus pantholopis DSM 102135T. The genomic DNA G+C content of Z15T is 42.48 mol%. Z15T has an average nucleotide identity (ANI) value of 81.19 % with S. pantholopis DSM 102135T and a DNA–DNA relatedness value of less than 70 % in the in-silico DNA–DNA hybridization (isDDH) with other species of genus Streptococcus deposited in the GenBank database. A whole-genome phylogenetic tree based on 246 core genes of 78 genomes of members of the genus Streptococcus indicated that Z15T represents a member of genus Streptococcus but one well separated from the currently recognized species. Z15T contains C18 : 1ω7c (25.5 %), C18 : 1ω9c (19.6 %), C16 : 0 (17.5 %) and C16 : 1ω9c (13.3 %) as its major cellular fatty acids. According to the morphological, biochemical and molecular phylogenetic features of the three novel isolates, they represent a novel species of the genus Streptococcus , and Streptococcus chenjunshii sp. nov. is thus proposed. The type strain is Z15T (=CGMCC 1.16529=DSM 106182).

Four Gram-stain-positive, catalase-negative, non-spore-forming, rod-shaped bacterial strains (zg-325T, zg329, dk561T and dk752) were isolated from the respiratory tract of marmot (Marmota himalayana) and the faeces of Tibetan gazelle (Procapra picticaudata) from the Qinghai-Tibet Plateau of PR China. The results of 16S rRNA gene sequence-based phylogenetic analyses indicated that strains zg-325T and dk561T represent members of the genus Actinomyces , most similar to Actinomyces denticolens DSM 20671T and Actinomyces ruminicola B71T, respectively. The DNA G+C contents of strains zg-325T and dk561T were 71.6 and 69.3 mol%, respectively. The digital DNA–DNA hybridization values of strains zg-325T and dk561T with their most closely related species were below the 70 % threshold for species demarcation. The four strains grew best at 35 °C in air containing 5 % CO2 on brain heart infusion (BHI) agar with 5 % sheep blood. All four strains had C18:1ω9c and C16:0 as the major cellular fatty acids. MK-8 and MK-9 were the major menaquinones in zg-325T while MK-10 was predominant in dk561T. The major polar lipids included diphosphatidylglycerol and phosphatidylinositol. On the basis of several lines of evidence from phenotypic and phylogenetic analyses, zg-325T and dk561T represent novel species of the genus Actinomyces , for which the name Actinomyces marmotae sp. nov. and Actinomyces procaprae sp. nov. are proposed. The type strains are zg-325T (=GDMCC 1.1724T=JCM 34091T) and dk561T (=CGMCC 4.7566T=JCM 33484T). We also propose, on the basis of the phylogenetic results herein, the reclassification of Actinomyces liubingyangii and Actinomyces tangfeifanii as Boudabousia liubingyangii comb. nov. and Boudabousia tangfeifanii comb. nov., respectively.

A novel filamentous Actinobacterium, designated strain FXJ1.1311T, was isolated from soil collected in Ngari (Ali) Prefecture, Qinghai-Tibet Plateau, western PR China. The strain showed antimicrobial activity against Gram-positive bacteria and Fusarium oxysporum. Results of phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FXJ1.1311T belonged to the genus Lentzea and showed the highest sequence similarity to Lentzea guizhouensis DHS C013T (98.04%). Morphological and chemotaxonomic characteristics supported its assignment to the genus Lentzea . The genome-wide average nucleotide identity between strain FXJ1.1311T and L. guizhouensis DHS C013T as well as other Lentzea type strains was <82.2 %. Strain FXJ1.1311T also formed a monophyletic line distinct from the known Lentzea species in the phylogenomic tree. In addition, physiological and chemotaxonomic characteristics allowed phenotypic differentiation of the novel strain from L. guizhouensis . Based on the evidence presented here, strain FXJ1.1311T represents a novel species of the genus Lentzea , for which the name Lentzea tibetensis sp. nov. is proposed. The type strain is FXJ1.1311T (=CGMCC 4.7383T=DSM 104975T).

A Gram-stain-positive, coccus-shaped, non-motile bacterium, designated CF-49T, was isolated from the cloacal content of a snow finch, which was incidentally captured in a plateau pika burrow on the Qinghai–Tibet Plateau, PR China. Analysis of the 16S rRNA gene sequence showed that strain CF-49T was closely related to Vagococcus elongatus CCUG 51432T (96.5 % similarity), Vagococcus fluvialis NCFB 2497T (96.0 %) and Vagococcus lutrae CCUG 39187T (95.9 %), whereas the similarity to another isolate (CF-210) was 99.9 %. Strains CF-49T and CF-210 grew optimally at 37 °C and pH 7.0 and in the presence of 0.5 % (w/v) NaCl. Acid was produced from N-acetylglucosamine, cellobiose, d-fructose, d-glucose, d-mannose, d-mannitol, maltose, d-ribose and salicin. The cell-wall peptidoglycan type was A4α (l-Lys–d-Asp). The major cellular fatty acids (>10 %) were C16 : 0 (35.6 %), C14 : 0 (17.3 %), C18 : 1 ω9c (16.2 %) and C16 : 1 ω9c (10.6 %). The predominant respiratory quinone was menaquinone MK-7 (68.8 %). The G+C content of the genomic DNA was 35.9 mol%. Digital DNA–DNA hybridization of strain CF-49T with V. fluvialis DSM 5731T, V. elongatus CCUG 51432Tand V. lutrae CCUG 39187T resulted in relatedness values of 21.4, 23.3 and 24.6 %, respectively. Based on results from polyphasic analyses, our two isolates are proposed to represent a novel species in the genus Vagococcus , with the name Vagococcus xieshaowenii. The type strain is CF-49T (=CGMCC 1.6436T=GDMCC 1.1588T=JCM 33477T).

Two Gram-stain-positive, catalase-positive and oxidase-negative, aerobic, non-motile, cellobiose-utilizing, short-rod-shaped strains (Z28T and Z29) were isolated from faeces of Tibetan antelope (Pantholops hodgsonii) collected on the Qinghai–Tibet Plateau. Strain Z28T shared 98.1, 98.0, 97.8 and 97.4 % 16S rRNA gene similarity, 24.1, 22.8, 23.2 and 26.3 % digital DNA–DNA hybridization relatedness and 80.8, 80.0, 80.7 and 80.9 % average nucleotide identity values with Cellulomonas oligotrophica DSM 24482T, Cellulomonas flavigena DSM 20109T, Cellulomonas iranensis DSM 14785T and Cellulomonas terrae JCM 14899T, respectively. Results from further phylogenetic analyses based on the 16S rRNA gene and 148 core genes indicated that strains Z28T and Z29 were closest to C. oligotrophica DSM 24482T and C. flavigena DSM 20109T, but clearly separated from the currently recognized species of the genus Cellulomonas . The genomic DNA G+C content of strain Z28T was 75.3 mol%. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C15 : 1 A, C16 : 0 and anteiso-C17 : 0. Ribose and mannose were detected as the whole-cell sugars. The major respiratory quinone was MK-9(H4) and ornithine was the diamino acid of the cell wall. The polar lipids present in strain Z28T were phosphatidylethanolamine, five phospholipids, two aminophospholipids, aminolipid and three unidentified lipids. Comparison of phenotypic and phylogenetic features between the two strains and the related organisms revealed that Z28T and Z29 represent a novel species of the genus Cellulomonas , for which the name Cellulomonas shaoxiangyii sp. nov. is proposed. The type strain is Z28T (=CGMCC 1.16477T=DSM 106200T).

Six aerobic, non-motile, non-haemolytic, Gram-stain-negative, oxidase-negative strains (185T, 187, 323-1T, 194, dk386T and dk771) were recovered from different faecal samples of Equus kiang on the Qinghai–Tibet Plateau. In the 16S rRNA gene sequences, one strain pair, 185T/187, shared highest similarity to Acinetobacter equi 114T (97.9 %), and the other two (323-1T/194 and dk771T/dk386) to Acinetobacter harbinensis CGMCC 1.12528T (98.6 and 97.0 %, respectively). Phylogenomic tree analysis showed that these six strains formed three separate clades in the genus Acinetobacter . Digital DNA–DNA hybridization values of each pair of the isolates with all members of the genus Acinetobacter were far below 70 %. The main cellular fatty acids of all six strains were C18 : 1  ω9c, C16 : 0 and summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c). Q-9 was the predominant respiratory quinone for strains 185T, 323-1T and dk386T. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Based on the genotypic, phenotypic and biochemical analyses, these six strains represent three novel species of the genus Acinetobacter , for which the names Acinetobacter lanii sp. nov., Acinetobacter shaoyimingii sp. nov. and Acinetobacter wanghuae sp. nov. are proposed. The type strains are 185T (=CGMCC 1.13636T=JCM 33607T), 323-1T (=CGMCC 1.13940T=JCM 33608T) and dk386T (=CGMCC 1.16589T=JCM 33592T), respectively.

An aerobic, Gram-stain-negative, bacterium, designated CLL3-39T was isolated from seashore sediment collected at a Tamarix chinensis forest in the Marine Ecology Special Reserve of Changyi, Shandong Province, PR China. Cells of strain CLL3-39T were olive-shaped and no flagellum was observed. Strain CLL3-39T grew optimally at 33 °C, pH 7.5 and salinity (sea salts) of 40 g l−1. The main fatty acids in the cell membrane of strain CLL3-39T comprised anteiso-C15 : 0 (22.3 %), iso-C15 : 0 (14.0 %), C16 : 0 (9.2 %) and summed feature 8 (contains C18 : 1  ω7c/C18 : 1  ω6c. 26. 7 %). The main polar lipids of CLL3-39T were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylcholine. The respiratory quinone was Q10. The G+C content of the genomic DNA of strain CLL3-39T was 69.6 mol%. The average nucleotide identity between CLL3-39T and Pseudoroseicyclus aestuarii DB-4T was 74.7 % and the in silico DNA–DNA hybridization value was 20.1 %. Phylogenetically, strain CLL3-39T belonged to the genus Pseudoroseicyclus , branching with only one type strain P. aestuarii DB-4T with 96.3 % 16S rRNA gene similarity, followed by Limimaricola cinnabarinus LL-001T (95.2 %). Based on its phenotypic, phylogenetic and chemotaxonomic characteristics, we propose strain CLL3-39T (=MCCC 1A14815T =KCTC 72665T) as a representative of a novel species in the genus Pseudoroseicyclus , for which the name Pseudoroseicyclus tamaricis sp. nov. is proposed.

An aerobic, Gram-stain negative, pale, rod-shaped, nitrogen-fixing bacterial strain, DDT-3T, was isolated from dichlorodiphenyltrichloroethane-contaminated soil in Liyang, PR China. Strain DDT-3T grew at temperatures ranging from 20 to 40 °C (optimum 30–37 °C) and a pH of between 5.0 and 10.0 (optimum pH 7.0–8.0). The G+C content of the total DNA was 70.1 mol%. The 16S rRNA gene sequence of strain DDT-3T showed the highest similarity to that of Pseudoxanthobacter soli CC4T (99.6 %), followed by Kaistia dalseonensis B6-8T (93.3 %), Kaistia soli 5YN9-8T (93.0 %) and Amorphus orientalis YIM D10T (93.0 %). Strain DDT-3T showed less than 92.6 % similarity with other species of the family Xanthobacteraceae . The major cellular fatty acids of strain DDT-3T were C19 : 0 cyclo ω8c (42.6 %), C16 : 0 (33.2 %) and C18 : 1ω7c (10.0 %). The only respiratory quinone was ubiquinone Q-10. The characteristic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The major polar lipids were glycolipid, lipid, phosphatidylcholine, aminolipid, phosphatidylmethylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The polyamine profile consisted of major amounts of putrescine (92.9 %) and minor amounts of spermidine (5.0 %) and spermine (2.1 %). These chemotaxonomic data support the affiliation of strain DDT-3T with the genus Pseudoxanthobacter . The DNA–DNA hybridization value between strain DDT-3T and strain CC4T was 47.8 % (reciprocal 44.3 %). DNA–DNA hybridization data as well as the biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strain DDT-3T and strain CC4T. Strain DDT-3T, therefore, represents a novel species of the genus Pseudoxanthobacter , for which the name Pseudoxanthobacter liyangensis sp. nov. is proposed. The type strain is DDT-3T ( = KACC 16601T = CCTCC AB 2013167T).

In the present study, four bacterial strains, two (S-713 T and 406) isolated from faecal samples of Tibetan antelopes and the other two (S-531 T and 1598) from leaves of dandelion collected on the Qinghai–Tibet Plateau of PR China, were analysed using a polyphasic approach. All four isolates were aerobic, rod-shaped, non-motile, oxidase-negative, Gram-stain-positive and catalase-positive. According to four phylogenetic trees, strain pairs S-713 T /406 and S-531 T /1598 form two independent branches belonging to the genus Nocardioides , and are closest to Nocardioides lianchengensis , Nocardioides dokdonensis , Nocardioides salarius , Nocardioides marinisabuli , Nocardioides psychrotolerans and Nocardioides szechwanensis . Although sharing MK8-(H 4 ) as their major isoprenoid quinone, strains S-713 T and S-531 T contained C 18 : 1  ω 9 c (24.64 and 16.34 %) and iso-C 16 : 0 (9.74 and 29.38 %), respectively, as their main fatty acids, with remarkable differences in their biochemical profiles but only slight ones in their optimal growth conditions. The chromosomes of strains S-713 T and S-531 T were 4 207 844 bp (G+C content, 73.0 mol%) and 4 809 817 bp (G+C content, 72.5 mol%), respectively. Collectively, the two strain pairs represent two separate novel species of the genus Nocardioides , for which the names Nocardioides dongkuii sp. nov. and Nocardioides lijunqiniae sp. nov. are proposed, with S-713 T (=JCM 33698 T =CGMCC 4.7660 T ) and S-531 T (=JCM 33468 T =CGMCC 4.7659 T ) as the respective type strains.
