Reference Strains

In order to clarify the taxonomic position of serotypes 20, 22 and 26 of Streptococcus suis , biochemical and molecular genetic studies were performed on isolates (SUT-7, SUT-286T, SUT-319, SUT-328 and SUT-380) reacted with specific antisera of serotypes 20, 22 or 26 from the saliva of healthy pigs as well as reference strains of serotypes 20, 22 and 26. Comparative recN gene sequencing showed high genetic relatedness among our isolates, but marked differences from the type strain S. suis NCTC 10234T, i.e. 74.8–75.7 % sequence similarity. The genomic relatedness between the isolates and other strains of species of the genus Streptococcus , including S. suis, was calculated using the average nucleotide identity values of whole genome sequences, which indicated that serotypes 20, 22 and 26 should be removed taxonomically from S. suis and treated as a novel genomic species. Comparative sequence analysis revealed 99.0–100 % sequence similarities for the 16S rRNA genes between the reference strains of serotypes 20, 22 and 26, and our isolates. Isolate STU-286T had relatively high 16S rRNA gene sequence similarity with S. suis NCTC 10234T (98.8 %). SUT-286T could be distinguished from S. suis and other closely related species of the genus Streptococcus using biochemical tests. Due to its phylogenetic and phenotypic similarities to S. suis we propose naming the novel species Streptococcus parasuis sp. nov., with SUT-286T ( = JCM 30273T = DSM 29126T) as the type strain.

A Gram-staining-negative, strictly aerobic, rod-shaped, pale-pink pigmented bacterial strain, designated TF8T, was isolated from leaf mould in Cheonan, Republic of Korea. Its taxonomic position was determined through a polyphasic approach. Optimal growth occurred on R2A agar without NaCl supplementation, at 25–28 °C and at pH 6.0–7.0. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain TF8T belongs to the genus Mucilaginibacter in the family Sphingobacteriaceae . The sequence similarity between 16S rRNA genes of strain TF8T and the type strains of other species of the genus Mucilaginibacter ranged from 92.1 to 94.7 %. The closest relatives of strain TF8T were Mucilaginibacter lutimaris BR-3T (94.7 %), M. soli R9-65T (94.5 %), M. litoreus BR-18T (94.5 %), M. rigui WPCB133T (94.0 %) and M. daejeonensis Jip 10T (93.8 %). The major isoprenoid quinone was MK-7 and the major cellular fatty acids were iso-C15 : 0 (33.0 %), summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c; 24.8 %) and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 13.0 %). The major polar lipids of TF8T were phosphatidylethanolamine and three unidentified aminophospholipids. The G+C content of the genomic DNA was 46.2 mol%. On the basis of the data presented here, strain TF8T is considered to represent a novel species of the genus Mucilaginibacter , for which the name Mucilaginibacter koreensis sp. nov. is proposed. The type strain is TF8T ( = KACC 17468T = JCM 19323T).

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.

Maize Field

A polyphasic taxonomic approach was used to characterize a Gram-stain-positive bacterium, designated strain CC-CFT480T, isolated from soil sampled in a maize field in Taiwan, ROC. Cells of strain CC-CFT480T were rod-shaped, motile with polar flagella, catalase-positive and oxidase-positive. Optimal growth occurred at 30 °С, pH 8 and 3 % NaCl. Phylogenetic analyses based on 16S rRNA genes revealed a distinct taxonomic position attained by strain CC-CFT480T associated with Cerasibacillus quisquiliarum (97.2 % sequence identity), Virgibacillus soli (95.7 %), Virgibacillus carmonensis (95.4 %) and Virgibacillus byunsanensis (95.2 %), and lower sequence similarity values to other species. Average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between strain CC-CFT480T and C. quisquiliarum were 74.2 and 20.1 %, respectively. Strain CC-CFT480T contained iso-C15:0, C16:1 ω7c alcohol and iso-C17:1 ω10c as the predominant fatty acids. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unknown aminophospholipids, one uncharacterized aminophospholipid and two unknown phospholipids. The major polyamine was spermidine. The DNA G+C content was 34.8 mol% and the predominant quinone was menaquinone 7 (MK-7). Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, ANI and dDDH analyses, strain CC-CFT480T is proposed to represent a novel Cerasibacillus species, for which the name Cerasibacillus terrae sp. nov. (type strain CC-CFT480T=BCRC 81216T=JCM 33498T).

A novel obligately anaerobic spirochete strain K2T was isolated from bottom marine sediments at Crater Bay of Yankicha Island (Kuril Islands, Russia). Strain K2T had helical shape and Gram-negatively stained. The optimal growth conditions were as follows: the optimum temperature was 28–30 °C with range 5–34 °C; optimal pH at 7.0–7.5 with range of 6.8–8.5; NaCl optimum at 3–3.5 % (w/v) and range of 1–7 % (w/v). Strain K2T was catalase- and oxidase-negative. Glucose fermentation products were acetate, lactate, ethanol, CO2, H2. The major fatty acids were C14 : 0, iso-C13 : 0, iso-C15:0, C14 : 0 DMA, iso-C15 : 0 DMA. The G+C content of genomic DNA was 43.2 mol%. Phylogenetic analyses of 16S rRNA genes showed that strain K2T belonged to the genus Oceanispirochaeta of the family Spirochaetaceae . The 16S rRNA gene sequence similarity of strain K2T and O. litoralis DSM 2029T and O. sediminicola DSM 104770T was 96 and 94 %, respectively. Based on the results of our study, we propose the name Oceanispirochaeta crateris sp. nov.; type strain K2T (=DSM 16308T=VKM B-3266T). Also, the taxonomic status of Spirochaeta perfilevii was revised: 16S rRNA genes sequence showed less than 89 % similarity to nearest phylogenetic neighbours. Therefore, we proposed to separate this species into a novel genus Thiospirochaeta - T. perfilievii gen. nov., comb. nov.

Endophytic Actinobacterium

A Gram-stain-positive, aerobic, non-motile, non-endospore-forming and rod-shaped actinobacterium, designated strain CMS6Z-2T, was isolated from a surface-sterilized branch of Kandelia candel collected from the Maowei Sea, Guangxi Zhuang Autonomous Region, PR China. Strain CMS6Z-2T grew at 10–37 °C (optimum, 37 °C), pH 6.0–9.0 (optimum, pH 7.0–8.0) and in the presence of 0–10.0 % (w/v) NaCl (optimum, 0–1.0 %). Strain CMS6Z-2T possessed meso-diaminopimelic acid as the diamino acid of the peptidoglycan and MK-8 (H4) as the predominant menaquinone. The major fatty acids were iso-C15 : 0, C16 : 0 and C18 : 1  ω9c. The polar lipids comprised diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and two unknown phospholipids. The G+C content of the genomic DNA was 74.1 mol%. Comparative analysis of 16S rRNA genes showed that strain CMS6Z-2T should be assigned to the genus Phycicoccus and its closest relative was Phycicoccus endophyticus IP6SC6T with 98.3 % similarity. Phylogenetic analyses based on 16S rRNA gene sequence and phylogenomic analysis based on core proteomes alignment revealed that strain CMS6Z-2T belonged to the genus Phycicoccus and formed a robust cluster with Phycicoccus endophyticus IP6SC6T within the genus Phycicoccus . The average nucleotide identity value and estimated digital DNA–DNA hybridization value between strain CMS6Z-2T and the type strain of Phycicoccus endophyticus were 81.5 and 23.9 %, respectively. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain CMS6Z-2T represents a novel species of the genus Phycicoccus , for which the name Phycicoccus flavus sp. nov. is proposed. The type strain is CMS6Z-2T (=KCTC 49240T=CGMCC4.7549T).

Two bacterial strains designated as W3-2-3T and HKS04T were isolated from mineral water and a soil sample, respectively, in the Republic of Korea. The 16S rRNA genes of the two strains shared a sequence similarity of 93.5 %. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains W3-2-3T and HKS04T formed a distinct lineage within the genus Nocardioides of the family Nocardioidaceae (order Propionibacteriales ). The closely related species of strain W3-2-3T were Nocardioides albidus (98.9 %), Nocardioides caeni (98.8 %), Nocardioides kongjuensis (98.6 %), Nocardioides aromaticivorans (98.5 %), Nocardioides nitrophenolicus (98.4 %), Nocardioides flava (98.2 %) and Nocardioides ginsengisoli (98.1 %). The closest species of strain HKS04T was Nocardioides halotolerans (98.7 %). The genome sizes of strains W3-2-3T and HKS04T were 4741198 and 5 120341 bp, respectively. The genomic DNA G+C contents of strains W3-2-3T and HKS04T were 73.3 and 72.1 mol%, respectively. The main fatty acids of strain W3-2-3T were C17:1 ω6c and iso-C16:0 and those of strain HKS04T were iso-C16:0 and iso-C16:0 H. The main polar lipids of both strains were diphosphatidylglycerol and phosphatidylglycerol and the predominant respiratory quinone was MK-8(H4), supporting the affiliation of these strains with the genus Nocardioides . Based on the results of biochemical, chemotaxonomic and phylogenetic analyses, two novel species, Nocardioides convexus W3-2-3T (KACC 21211T=LMG 31251T) and Nocardioides anomalus HKS04T (KACC 18879T=LMG 31249T), are proposed.

Bacteria of the genus Paenibacillus are relevant to humans, animals and plants. The species Paenibacillus massiliensis and Paenibacillus panacisoli are Gram-stain-positive and endospore-forming bacilli isolated from a blood culture of a leukemia patient and from soil of a ginseng field, respectively. Comparative analyses of their 16S rRNA genes revealed that the two Paenibacillus species could be synonyms (99.3% sequence identity). In the present study we performed different genomic analyses in order to evaluate the phylogenetic relationship of these micro-organisms. Paenibacillus massiliensis DSM 16942T and P. panacisoli DSM 21345T presented a difference in their G+C content lower than 1 mol%, overall genome relatedness index values higher than the species circumscription thresholds (average nucleotide identity, 95.57 %; genome-wide ANI, =96.51 %; and orthologous ANI, 96.25 %), and a monophyletic grouping pattern in the phylogenies of the 16S rRNA gene and the proteome core. Considering that these strains present differential biochemical capabilities and that their computed digital DNA–DNA hybridization value is lower than the cut-off for bacterial subspecies circumscription, we suggest that each of them form different subspecies of P. massiliensis , Paenibacillus massiliensis subsp. panacisoli subsp. nov. (type strain DSM 21345T) and Paenibacillus massiliensis subsp. massiliensis subsp. nov. (type strain DSM 16942T).

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).

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).

Two strains of a Gram-staining-positive species were isolated from German bulk tank milk. On the basis of their 16S rRNA sequences they were affiliated to the genus Facklamia but could not be assigned to any species with a validly published name. Facklamia miroungae ATCC BAA-466T (97.3 % 16S rRNA sequence similarity), Facklamia languida CCUG 37842T (96.9 %), and Facklamia hominis CCUG 36813T (96.6 %) are the closest relatives. In the 16S rRNA phylogeny and in the core-genome phylogeny strains WS 5301T and WS 5302 form a well-supported, separate lineage. Pairwise average nucleotide identity calculated using MUMmer (ANIm) between WS 5301T and type strains of other Facklamia species is well below the species cut-off (95 %) and ranges from 83.4 to 87.7 %. The DNA G+C content of the type strain is 36.4 mol% and the assembly size of the genome is 2.2 Mb. Cells of WS 5301T are non-motile, non-endospore-forming, oxidase-negative, catalase-negative and facultatively anaerobic cocci. The fastidious species grows at 10–40 °C and with up to 7.0 % (w/v) NaCl in BHI supplemented with 5 g l−1 yeast extract. Major polar lipids are phosphatidylglycerol, diphosphatidylglycerol and two glycolipids. Predominant fatty acids are C16 : 1ω9c and C18 : 1ω9c. On the basis of their genomic, physiological and chemotaxonomic characteristics the strains examined in this study represent the same, hitherto unknown species. We propose the name Facklamia lactis sp. nov. for which WS 5301T (=DSM 111018T=LMG 31861T) is the type strain and WS 5302 (=DSM 111019=LMG 31862) is an additional strain of this novel species.
