Two independent strains of a Leptotrichia species (ES3154-GLUT and ES2714_GLU) were isolated from the oral cavity of northern elephant seals (Mirounga angustirostris) that were admitted to The Marine Mammal Centre facilities in California, USA. The strains were isolated from oral swabs by cultivation in PPLO broth supplemented with serum, penicillin and colistin in anaerobic conditions. The strains were Gram-negative, pleomorphic, indole-, oxidase- and catalase-negative, non-spore-forming, non-motile rods/coccobacilli in short chains. The 16S rRNA gene sequence of these strains shared 94.42 % nucleotide similarity with Oceanivirga salmonicida AVG 2115T but demonstrated ≤86.00–92.50 % nucleotide similarity to the 16S rRNA genes of other species of the family Leptotrichiaceae . The genome was sequenced for strain ES3154-GLUT. Average nucleotide identity values between strain ES3154-GLUT and 15 type strain genomes from the family Leptotrichiaceae ranged from 66.74 % vs. Sebaldella termitidis to 73.35 % vs. O. salmonicida . The whole genome phylogeny revealed that the novel species was most closely related to O. salmonicida AVG 2115T. This relationship was also confirmed by nucleotide similarity and multilocus phylogenetic analyses employing various housekeeping genes (partial 23S rRNA, rpoB, rpoC, rpoD, polC, adh, gyrA and gyrB genes). Chemotaxonomic and phenotypical features of strain ES3154-GLUT were in congruence with closely related members of the family Leptotrichiaceae , represented by similar enzyme profiles and fatty acid patterns. MALDI-TOF MS analysis was capable to clearly discriminate strain ES3154-GLUT from all currently described taxa of the family Leptotrichiaceae . Based on these data, we propose a novel species of the genus Oceanivirga , for which the name Oceanivirga miroungae sp. nov. is proposed with the type strain ES3154-GLUT (=DSM 109740T=CCUG 73653T=ATCC TSD-189T=NCTC 14411T) and one representative strain ES2714_GLU. The G+C content is 26.82 %, genome size is 1 356 983 bp.

In 1983, Mycoplasma sp. strain 1220 was isolated in Hungary from the phallus lymph of a gander with phallus inflammation. Between 1983 and 2017, Mycoplasma sp. 1220 was also identified and isolated from the respiratory tract, liver, ovary, testis, peritoneum and cloaca of diseased geese in several countries. Seventeen studied strains produced acid from glucose and fructose but did not hydrolyse arginine or urea, and all grew under aerobic, microaerophilic and anaerobic conditions at 35 to 37 ˚C in either SP4 or pleuropneumonia-like organism medium supplemented with glucose and serum. Colonies on agar showed a typical fried-egg appearance and transmission electron microscopy revealed a typical mycoplasma cellular morphology. Molecular characterization included analysis of the following genetic loci: 16S rRNA, 23S rRNA, 16S–23S rRNA ITS, rpoB, rpoC, rpoD, uvrA, parC, topA, dnaE, fusA and pyk. The genome was sequenced for type strain 1220T. The 16S rRNA gene sequences of studied strains of Mycoplasma sp. 1220 shared 99.02–99.19 % nucleotide similarity with M. anatis strains but demonstrated ≤95.00–96.70 % nucleotide similarity to the 16S rRNA genes of other species of the genus Mycoplasma . Phylogenetic, average nucleotide and amino acid identity analyses revealed that the novel species was most closely related to Mycoplasma anatis . Based on the genetic data, we propose a novel species of the genus Mycoplasma , for which the name Mycoplasma anserisalpingitidis sp. nov. is proposed with the type strain 1220T (=ATCC BAA-2147T=NCTC 13513T=DSM 23982T). The G+C content is 26.70 mol%, genome size is 959110 bp.

Two Gram-stain-negative, aerobic, non-motile bacteria, designated KMS-5T and CYK-10T, were isolated from freshwater environments. 16S rRNA gene sequence similarity results indicated that these two novel strains belong to the family Rhodobacteraceae . Strain KMS-5T is closely related to species within the genus Tabrizicola (96.1–96.8 % sequence similarity) and Cypionkella (96.5–97.0 %). Strain CYK-10T is closest to Rhodobacter thermarum YIM 73036T with 96.6 % sequence similarity. Phylogenetic analyses based on 16S rRNA gene sequences and an up-to-date bacterial core gene set showed that strain KMS-5T is affiliated with species in the genus Tabrizicola and strain CYK-10T is placed in a distinct clade with Rhodobacter blasticus ATCC 33485T, Rhodobacter thermarum YIM 73036T and Rhodobacter flagellatus SYSU G03088T. These two strains shared common chemotaxonomic features comprising Q-10 as the major quinone, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine as the principal polar lipids, and C18 : 1  ω7c as the main fatty acid. The average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization values between these two novel isolates and their closest relatives were below the cut-off values of 95–96, 90 and 70 %, respectively, used for species demarcation. The obtained polyphasic taxonomic data suggested that strain KMS-5T represents a novel species within the genus Tabrizicola , for which the name Tabrizicola oligotrophica sp. nov. is proposed with KMS-5T (=BCRC 81196T=LMG 31337T) as the type strain, and strain CYK-10T should represent a novel species of the genus Rhodobacter , for which the name Rhodobacter tardus sp. nov. is proposed with CYK-10T (=BCRC 81191T=LMG 31336T) as the type strain.

Four unknown strains belonging to the genus Arthrobacter were isolated from plateau wildlife on the Qinghai–Tibet Plateau of PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the four isolates were separated into two clusters. Cluster I (strains 785T and 208) had the greatest 16S rRNA gene sequence similarity to Arthrobacter citreus (98.6 and 98.7 %, respectively), Arthrobacter luteolus (98.0 and 98.1%, respectively), Arthrobacter gandavensis (97.9 and 98.0 %, respectively) and Arthrobacter koreensis (97.6 and 97.7 %, respectively). Likewise, cluster II (strains J391T and J915) had the highest sequence similarity to Arthrobacter ruber (98.6 and 98.3 %, respectively) and Arthrobacter agilis (98.1 and 97.9  %, respectively). Average nucleotide identity and the digital DNA–DNA hybridization values illustrated that the two type strains, 785T and J391T, represented two separate novel species that are distinct from all currently recognized species in the genus Arthrobacter . These strains had DNA G+C contents of 66.0–66.1 mol% (cluster I) and 68.0 mol% (cluster II). The chemotaxonomic properties of strains 785T and J391T were in line with those of the genus Arthrobacter : anteiso-C15:0 (79.3 and 40.8 %, respectively) as the major cellular fatty acid, MK-8(H2) (65.8 %) or MK-9(H2) (75.6 %) as the predominant respiratory quinone, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, glycolipids and phospholipid, and A3α or A4α as the cell wall peptidoglycan type. On the basis of our results, two novel species in the genus Arthrobacter are proposed, namely Arthrobacter yangruifuii sp. nov. (type strain, 785T=CGMCC 1.16725T=GDMCC 1.1592T=JCM 33491T) and Arthrobacter zhaoguopingii sp. nov. (type strain, J391T=CGMCC 1.17382T=GDMCC 1.1667T=JCM 33841T).

A non-motile, yellow–orange-pigmented bacterial strain, designated HME6664T, was isolated from Lake Soyang, Republic of Korea. The major fatty acids of strain HME6664T were summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 44.7 %) and iso-C15 : 0 (20.2 %). The DNA G+C content was 40.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME6664T formed a lineage within the genus Mucilaginibacter . Strain HME6664T was closely related to Mucilaginibacter ximonensis (96.7 %), Mucilaginibacter dorajii (96.5 %) and Mucilaginibacter lappiensis (96.3 %). On the basis of the evidence presented in this study, strain HME6664T represents a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter soyangensis sp. nov., is proposed. The type strain is HME6664T ( = KCTC 23261T = CECT 7824T).

Three strains of an anaerobic, Gram-stain-positive coccobacillus were isolated from the intestines of mice. These strains shared 100 % similarity in their 16S rRNA gene sequences, but were distantly related to any described members of the family Lachnospiraceae (<94 %). The most closely related species with names that have standing in nomenclature were Robinsoniella peoriensis , Ruminococcus gnavus , Blautia producta and Clostridium xylanolyticum . Phylogenetic relationships based on 16S rRNA gene sequence analysis were confirmed by partial sequencing of hsp60 genes. The use of an in-house database search pipeline revealed that the new isolates are most prevalent in bovine gut samples when compared with human and mouse samples for Ruminococcus gnavus and B. producta . All three isolated strains shared similar cellular fatty acid patterns dominated by C16 : 0 methyl ester. Differences in the proportions of C12 : 0 methyl ester, C14 : 0 methyl ester and C18 : 1 cis-11 dimethyl acetal were observed when compared with phylogenetically neighbouring species. The major short-chain fatty acid produced by strain SRB-530-5-HT was acetic acid. This strain tested positive for utilization of d-fructose, d-galacturonic acid, d-malic acid, l-alanyl l-threonine and l-glutamic acid but was negative for utilization of amygdalin, arbutin, α-d-glucose, 3-methyl d-glucose and salicin, in contrast to the type strain of the closest related species Robinsoniella peoriensis . The isolates were not able to use mannitol for growth. Based on genotypic, phenotypic and chemotaxonomic characteristics, we propose to create the new genus and species Murimonas intestini gen. nov., sp. nov. to accommodate the three strains SRB-530-5-HT ( = DSM 26524T = CCUG 63391T) (the type strain of Murimonas intestini), SRB-509-4-S-H ( = DSM 27577 = CCUG 64595) and SRB-524-4-S-H ( = DSM 27578 = CCUG 64594).

A Gram-stain-positive, non-motile rod, designated strain SGM3-12T, was isolated from paddy soil in Suwon, Republic of Korea. 16S rRNA gene sequence analysis revealed that the strain represented a novel member of the family Microbacteriaceae . The nearest phylogenetic neighbour was Leifsonia kribbensis MSL-13T (97.4 % 16S rRNA gene sequence similarity). Strain SGM3-12T and Leifsonia kribbensis MSL-13T formed a distinct cluster within the family Microbacteriaceae . Strain SGM3-12T contained MK-12(H2) and MK-11(H2) as the predominant menaquinones with moderate amounts of MK-12 and MK-11; anteiso-C15 : 0 and iso-C16 : 0 as the major cellular fatty acids (>10 % of total); and diphosphatidylglycerol, phosphatidylglycerol and unidentified glycolipids as the polar lipids. The peptidoglycan type of the isolate was B1δ with l-Lys as the diagnostic cell-wall diamino acid. On the basis of these results, strain SGM3-12T represents a novel species within a new genus, for which the name Lysinimonas soli gen. nov., sp. nov. is proposed (the type strain of the type species is SGM3-12T = KACC 13362T = NBRC 107106T). It is also proposed that Leifsonia kribbensis be transferred to this genus as Lysinimonas kribbensis comb. nov. (the type strain is MSL-13T = DSM 19272T = JCM 16015T = KACC 21108T = KCTC 19267T).

A Gram-type positive, Gram-reaction variable, non-motile, psychrophilic actinobacterium, designated Cr8-25T, was isolated from alpine glacier cryoconite and was able to grow well over a temperature range of 1–15 °C. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Cr8-25T belonged to the family Microbacteriaceae and showed highest 16S rRNA gene sequence similarity with Klugiella xanthotipulae 44C3T (97.0 %). However, strain Cr8-25T could be differentiated from the type strain of K. xanthotipulae on the level of genomospecies by a DNA–DNA relatedness value of only 37.2 %. Strain Cr8-25T contained a cell-wall peptidoglycan that was cross-linked according to the B-type, which is based on 2,4-diaminobutyric acid. The cell wall contained the sugars galactose, fucose and rhamnose. The predominant cellular fatty acids of strain Cr8-25T were C15 : 0 anteiso (64.6 %) and iso-C16 : 0 (22.5 %) and the major menaquinones were MK-11 and MK-10. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and unknown glycolipids. The G+C content of the genomic DNA was 58.8 mol%. On the basis of the phenotypic characteristics, phylogenetic and chemotaxonomic analyses and DNA–DNA relatedness data, strain Cr8-25T represents a novel species of a new genus in the family Microbacteriaceae , for which the name Alpinimonas psychrophila gen. nov., sp. nov. is proposed. The type strain is Cr8-25T ( = DSM 23737T = LMG 26215T).

Five strains of anaerobic, Gram-negative bacilli isolated from the human oral cavity were subjected to a comprehensive range of phenotypic and genotypic tests and were found to comprise a homogeneous group. Phylogenetic analysis of full-length 16S rRNA gene sequences showed that these strains represented a novel group within the family Prevotellaceae , and the most closely related species was Prevotella tannerae . P. tannerae and the novel taxon are deeply branched from the genus Prevotella , with sequence identities to the type strain of the type species of Prevotella , Prevotella melaninogenica , of 82.2 and 85.6 %, respectively. The novel genus Alloprevotella gen. nov. is proposed to accommodate the novel species Alloprevotella rava gen. nov., sp. nov. and the previously named Prevotella tannerae Moore et al. 1994 as Alloprevotella tannerae gen. nov., comb. nov. The type species is Alloprevotella tannerae. The type strain of Alloprevotella rava is 81/4-12T ( = DSM 22548T  = CCUG 58091T) and the type strain of Alloprevotella tannerae is ATCC 51259T  = CCUG 34292T  = CIP 104476T  = NCTC 13073T. Alloprevotella rava is weakly to moderately saccharolytic and produces moderate amounts of acetic acid and major amounts of succinic acid as end products of fermentation. Strains are sensitive to 20 % bile and hydrolyse gelatin. The principal cellular long-chain fatty acids are anteiso-C15 : 0, iso-C15 : 0, C16 : 0, iso-C17 : 0 and iso-C17 : 0 3-OH. The G+C content of the DNA of the type strain is 47 mol%.

Strains RU-16T, RU-28, RU-04T and PU-02T were isolated from the gut of the African mole cricket, Gryllotalpa africana. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the strains belonged to the family Microbacteriaceae . All four strains were most closely related to Curtobacterium ginsengisoli DCY26T (below 97 % 16S rRNA gene sequence similarity). These isolates were Gram-stain-positive, motile (by gliding), rod-shaped and exhibited ivory-coloured colonies. Their chemotaxonomic properties included MK-11 as the major respiratory quinone, ornithine as the cell-wall diamino acid, acetyl as the acyl type of the peptidoglycan, cyclohexyl-C17 : 0 as the major fatty acid and phosphatidylglycerol and diphosphatidylglycerol as the major polar lipids. On the basis of phenotypic, chemotaxonomic and phylogenetic analyses, we propose a new genus in the family Microbacteriaceae , Gryllotalpicola gen. nov., with three novel species, Gryllotalpicola daejeonensis sp. nov. (type strain RU-04T  = KCTC 13809T  = JCM 17590T), Gryllotalpicola koreensis sp. nov. (type strain RU-16T  = KCTC 13810T  = JCM 17591T) and Gryllotalpicola kribbensis sp. nov. (type strain PU-02T  = KCTC 13808T  = JCM 17593T). Gryllotalpicola koreensis is the type species of the genus. Additionally, we propose that Curtobacterium ginsengisoli should be reclassified in the genus as Gryllotalpicola ginsengisoli comb. nov. (type strain DCY26T  = KCTC 13163T  = JCM 14773T).

The saline-alkaline lakes (soda lakes) are the habitat of the haloalkaliphilic cyanobacterium Anabaenopsis elenkinii, the type species of this genus. To obtain robust phylogeny of this type species, we have generated whole-genome sequencing of the bloom-forming Anabaenopsis elenkinii strain CCIBt3563 isolated from a Brazilian soda lake. This strain presents the typical morphology of A. elenkinii with short and curved trichomes with apical heterocytes established after separation of paired intercalary heterocytes and also regarding to cell dimensions. Its genome size is 4 495 068 bp, with a G+C content of 41.98 %, a total of 3932 potential protein coding genes and four 16S rRNA genes. Phylogenomic tree inferred by RAxML based on the alignment of 120 conserved proteins using GTDB-Tk grouped A. elenkinii CCIBt3563 together with other genera of the family Aphanizomenonaceae. However, the only previous available genome of Anabaenopsis circularis NIES-21 was distantly positioned within a clade of Desikacharya strains, a genus from the family Nostocaceae. Furthermore, average nucleotide identity values from 86–98 % were obtained among NIES-21 and Desikacharya genomes, while this value was 76.04 % between NIES-21 and the CCIBt3563 genome. These findings were also corroborated by the phylogenetic tree of 16S rRNA gene sequences, which also showed a strongly supported subcluster of A. elenkinii strains from Brazilian, Mexican and Kenyan soda lakes. This study presents the phylogenomics and genome-scale analyses of an Anabaenopsis elenkinii strain, improving molecular basis for demarcation of this species and framework for the classification of cyanobacteria based on the polyphasic approach.
