Genomic Scale

To clarify the evolutionary relationships and classification of Bacillus species, comprehensive phylogenomic and comparative analyses were performed on >300 Bacillus/Bacillaceae genomes. Multiple genomic-scale phylogenetic trees were initially reconstructed to identify different monophyletic clades of Bacillus species. In parallel, detailed analyses were performed on protein sequences of genomes to identify conserved signature indels (CSIs) that are specific for each of the identified clades. We show that in different reconstructed trees, most of the Bacillus species, in addition to the Subtilis and Cereus clades, consistently formed 17 novel distinct clades. Additionally, some Bacillus species reliably grouped with the genera Alkalicoccus, Caldalkalibacillus, Caldibacillus, Salibacterium and Salisediminibacterium . The distinctness of identified Bacillus species clades is independently strongly supported by 128 identified CSIs which are unique characteristics of these clades, providing reliable means for their demarcation. Based on the strong phylogenetic and molecular evidence, we are proposing that these 17 Bacillus species clades should be recognized as novel genera, with the names Alteribacter gen. nov., Ectobacillus gen. nov., Evansella gen. nov., Ferdinandcohnia gen. nov., Gottfriedia gen. nov., Heyndrickxia gen. nov., Lederbergia gen. nov., Litchfieldia gen. nov., Margalitia gen. nov., Niallia gen. nov., Priestia gen. nov., Robertmurraya gen. nov., Rossellomorea gen. nov., Schinkia gen. nov., Siminovitchia gen. nov., Sutcliffiella gen. nov. and Weizmannia gen. nov. We also propose to transfer ‘ Bacillus kyonggiensi s’ to Robertmurraya kyonggiensis sp. nov. (type strain: NB22=JCM 17569T=DSM 26768). Additionally, we report 31 CSIs that are unique characteristics of either the members of the Subtilis clade (containing the type species B. subtilis ) or the Cereus clade (containing B. anthracis and B. cereus ). As most Bacillus species which are not part of these two clades can now be assigned to other genera, we are proposing an emended description of the genus Bacillus to restrict it to only the members of the Subtilis and Cereus clades.

An aerobic, Gram-stain-negative, rod-shaped bacterium with a single polar flagellum, designated CC-OPY-1T, was isolated from an oil-contaminated site in Taiwan. CC-OPY-1T produces siderophores, and can grow at temperatures of 25–37 °C and pH 5.0–9.0 and tolerate <5 % (w/v) NaCl. The 16S rRNA gene sequence analysis of CC-OPY-1T showed high pairwise sequence similarity to Pseudomonas alcaligenes BCRC 11893T (97.1 %), Pseudomonas. alcaliphila DSM 17744T (97.1 %), Pseudomonas tuomuerensis JCM 14085T (97.1 %), Pseudomonas toyotomiensis JCM 15604T (96.9 %) and lower sequence similarity to remaining species of the genus Pseudomonas . The phylogenetic trees reconstructed based on gyrB and rpoB gene sequences supported the classification of CC-OPY-1T as a novel member of the genus Pseudomonas . The predominant quinone system of strain CC-OPY-1T was ubiquinone (Q-9) and the DNA G+C content was 68.4±0.3 mol%. The major fatty acids were C12 : 0, C16 : 0, C17 : 0 cyclo and summed features 3 and 8 consisting of C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c, respectively. The major polar lipids were phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), phosphatidylcholine (PC) and two unknown phospholipids (PL1–2). Due to distinct phylogenetic, phenotypic and chemotaxonomic features, CC-OPY-1T is proposed to represent a novel species within the genus Pseudomonas for which the name Pseudomonas sagittaria sp. nov. is proposed. The type strain is CC-OPY-1T ( = BCRC 80399T = JCM 18195T).

The genus Izhakiella was established and designated as a member of the family Enterobacteriaceae in 2016. Although the taxonomical classification of most members in this family has been relatively resolved after two reclassifications in 2016 and 2017, the classification of the genus Izhakiella remains ambiguous. In this study, a polyphasic approach was used to provide evidence supporting the fact that the genus Izhakiella should no longer be considered a member of Enterobacteriaceae and proposes its reclassification into the family Erwiniaceae . The phylogenetic tree of type species in the families Enterobacteriaceae and Erwiniaceae based on the sequences of the 16S rRNA gene, rpoB housekeeping gene, and the whole-genome comprising the 92 core genes revealed that the genus Izhakiella forms a phylogenetic lineage within the family Erwiniaceae . The average nucleotide identity (ANI) value of the type species with genus Izhakiella was found to be higher for the family Erwiniaceae than that for the family Enterobacteriaceae . Notably, 12 conserved signature indels (CSIs) that are exclusively shared among the Erwiniaceae clade members were found in the type strains of the genus Izhakiella . Based on these analyses, this study suggests the reclassification of I. capsodis and I. australiensis into the family Erwiniaceae .

The Family

The evolutionary relationships among species of the family Pseudomonadaceae were examined based on 255 available genomes representing >85 % of the species from this family. In a phylogenetic tree based on concatenated sequences of 118 core proteins, most species of the genus Pseudomonas grouped within one large cluster which also included members of the genera Azotobacter and Azomonas . Within this large cluster 18–30 clades/subclades of species of the genus Pseudomonas consisting of between 1 and 36 species, were observed. However, a number of species of the genus Pseudomonas branched outside of this main cluster and were interspersed among other genera of the family Pseudomonadaceae . This included a strongly supported clade (Pertucinogena clade) consisting of 19 mainly halotolerant species. The distinctness of this clade from all other members of the family Pseudomonadaceae is strongly supported by 24 conserved signature indels (CSIs) in diverse proteins that are exclusively found in all members of this clade. Nine uncharacterized members of the genus Pseudomonas also shared these CSIs and they branched within the Pertucinogena clade, indicating their affiliation to this clade. On the basis of the strong evidence supporting the distinctness of the Pertucinogena clade, we are proposing transfer of species from this clade into a novel genus Halopseudomonas gen. nov. Pseudomonas caeni also branches outside of the main cluster and groups reliably with Oblitimonas alkaliphila and Thiopseudomonas denitrificans . Six identified CSIs are uniquely shared by these three species and we are proposing their integration into the emended genus Thiopseudomonas , which has priority over the name Oblitimonas . We are also proposing transfer of the deep-branching Pseudomonas hussainii , for which 22 exclusive CSIs have been identified, into the genus Atopomonas gen. nov. Lastly, we present strong evidence that the species Pseudomonas cissicola and Pseudomonas geniculata are misclassified into the genus Pseudomonas and that they are specifically related to the genera Xanthomonas and Stenotrophomonas , respectively. In addition, we are also reclassifying ‘Pseudomonas acidophila’ as Paraburkholderia acidicola sp. nov. (Type strain: G-6302=ATCC 31363=BCRC 13035).

Food Waste Compost

A taxonomic study was carried out on a novel aerobic bacterial strain, designated CC-CY503T, isolated from food-waste compost in Taiwan. Cells were Gram-stain-negative short rods, motile by means of a monopolar flagellum. Strain CC-CY503T was able to grow at 20–50 °C and pH 6.0–10.0 and to tolerate <6 % NaCl (w/v). Phylogenetic analysis of 16S rRNA gene sequences showed that this bacterium belonged to the genus Pseudomonas , with Pseudomonas pertucinogena ATCC 190T as the closest neighbour, sharing a sequence similarity of 97.9 %. The DNA–DNA relatedness value of strain CC-CY503T with P. pertucinogena ATCC 190T was 37.8±2.3 %. The phylogenetic trees reconstructed based on gyrB and rpoB gene sequences supported the classification of strain CC-CY503T as a novel member of the genus Pseudomonas . The predominant quinone system was ubiquinone (Q-9) and the DNA G+C content was 63.1±0.4 mol%. The major fatty acids were C12 : 0, C16 : 0, C17 : 0 cyclo, C19 : 0 cyclo ω8c and summed features 3 and 8 consisting of C16 : 1ω7c/C16 : 1ω6c and C18 : 1ω7c/C18 : 1ω6c, respectively. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylcholine. On the basis of its distinct phylogenetic, phenotypic and chemotaxonomic features, strain CC-CY503T ( = BCRC 80437T = JCM 18415T) is proposed to represent a novel species within the genus Pseudomonas , for which the name Pseudomonas formosensis sp. nov. is proposed.

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).

A Gram-staining-negative bacterium, strain TS-T86T, was isolated from Lake Tuosu, a saline lake (salinity 5.4 %, w/w) in Qaidam basin, China. Its taxonomic position was determined by using a polyphasic approach. Strain TS-T86T was strictly heterotrophic, aerobic and catalase- and oxidase-positive. Cells were non-spore-forming, non-motile rods, 0.4–0.6 µm wide and 1.2–2.3 µm long. Growth was observed in the presence of 0–9.0 % (w/v) NaCl (optimum, 2.0 %), at 4–35 °C (optimum, 25 °C) and at pH 7.0–10.5 (optimum, pH 8.5–9.0). Strain TS-T86T contained MK-7 as the predominant respiratory quinone. The major fatty acids (>10 %) were iso-C15 : 1 G, iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipids consisted of phosphatidylethanolamine, an unknown phospholipid, six unidentified aminolipids and two uncharacterized lipids. The DNA G+C content was 35 mol% (T m). Phylogenetic trees based on 16S rRNA gene sequences showed that strain TS-T86T was associated with the genus Belliella , and showed the highest sequence similarity to Belliella baltica BA134T (98.5 %) and then to Belliella kenyensis No.164T (95.7 %) and Belliella pelovolcani CC-SAL-25T (95.3 %). DNA–DNA relatedness of strain TS-T86T to Belliella baltica DSM 15883T was 32±3 %. It is concluded that strain TS-T86T represents a novel species of the genus Belliella , for which the name Belliella aquatica sp. nov. is proposed. The type strain is TS-T86T ( = CGMCC 1.12479T = JCM 19468T).

A novel actinobacterium, designated strain NEAU-351T, was isolated from cow dung collected from Shangzhi, Heilongjiang Province, northeast PR China and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NEAU-351T belonged to the genus Nocardia , with the highest similarity (98.96 %) to Nocardia takedensis DSM 44801T and less than 98.0 % identity with other type strains of the genus Nocardia . The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The major menaquinone was observed to contain MK-8(H4, ω-cycl) (78.2 %). The fatty acid profile mainly consisted of C16 : 0, C18 : 1  ω9c and 10-methyl C18 : 0. Mycolic acids were present. The genomic DNA G+C content of strain NEAU-351T was 68.1 mol%. In addition, the average nucleotide identity values between strain NEAU-351T and its reference strains, Nocardia takedensis DSM 44801T and Nocardia arizonensis NBRC 108935T, were found to be 81.4 and 82.9 %, respectively, and the level of digital DNA–DNA hybridization between them were 24.8 % (22.5–27.3 %) and 26.3 % (24–28.8 %), respectively. Here we report on the taxonomic characterization and classification of the isolate and propose that strain NEAU-351T represents a new species of the genus Nocardia , for which the name Nocardia bovistercoris is proposed. The type strain is NEAU-351T (=CCTCC AA 2019090T=DSM 110681T).

Parvularcula flava was proposed as a novel member of genus Parvularcula in 2016. Some time earlier, Aquisalinus flavus has been proposed as a novel species of a novel genus named Aquisalinus . When comparing the 16S rRNA gene sequences of type strains P. flava NH6-79T and A. flavus D11M-2T, they showed 97.9 % sequence identity, much higher than the sequence identities 92.7–94.3 % between P. flava NH6-79T and type strains in the genus Parvularcula , indicating that the later proposed novel taxon Parvularcula flava need reclassification. The phylogenetic trees based on 16S rRNA gene sequences and genome sequences both showed that P. flava NH6-79T and A. flavus D11M-2T formed a separated branch away from strains in the genera Parvularcula , Marinicaulis and Amphiplicatus . The average amino acid identity and average nucleotide identity values of P. flava NH6-79T and A. flavus D11M-2T were 87.9 and 85.0 %, respectively, much higher than the values between P. flava NH6-79T and other closely related type strains (54.3 %–58.1 % and 68.6–70.4 %, respectively). P. flava NH6-79T and A. flavus D11M-2T also contained summed feature 8 (C18 : 1  ω6c and/or C18 : 1  ω7c) and C16 : 0 as major fatty acids, distinguishing them from other closely related taxa. Based on the results of the phylogenetic, comparative genomic and phenotypic analyses, Parvularcula flava should be reclassified as Aquisalinus luteolus nom. nov. and the description of genus Aquisalinus is emended.

The phylogenetic analysis based on 16S rRNA gene sequences along with the whole genome (92 core gene sets) revealed that AGMB 02131T formed a group within the genus Peribacillus , and showed the highest sequence similarity with Peribacillus endoradicis DSM 28131T (96.9 %), following by Peribacillus butanolivorans DSM 18926T (96.6 %). The genome of AGMB 02131T comprised 70 contigs, the chromosome length was 4 038 965 bp and it had a 38.5 % DNA G+C content. Digital DNA–DNA hybridization revealed that AGMB 02131T displayed 21.4 % genomic DNA relatedness with the most closely related strain, P. butanolivorans DSM 18926T. AGMB 02131T contains all of the conserved signature indels that are specific for members of the genus Peribacillus . The major cellular fatty acids (>10 %) of AGMB 02131T were C18 : 1ω9c, C18:0 and C16 : 0. The major polar lipids present were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. On the basis of the phenotypic, phylogenetic, genomic and chemotaxonomic features, AGMB 02131T represents a novel species of the genus Peribacillus , for which the name Peribacillus faecalis sp. nov. is proposed. The type strain is AGMB 02131T (=KCTC 43221T=CCTCC AB 2020077T).

Tidal Flat Sediment

A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped bacterial strain, BB-Mw22T, was isolated from a tidal flat sediment of the South Sea in South Korea. It grew optimally at 30–37 °C, at pH 7.0–7.5 and in the presence of 2–3 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain BB-Mw22T belonged to the genus Kangiella and the cluster comprising Kangiella species and strain BB-Mw22T was clearly separated from other taxa. Strain BB-Mw22T exhibited 95.3–98.7 % 16S rRNA gene sequence similarity to the type strains of recognized Kangiella species. Strain BB-Mw22T contained Q-8 as the predominant ubiquionone and iso-C15 : 0 and iso-C11 : 0 3-OH as the major fatty acids. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and one unidentified aminolipid. The DNA G+C content of strain BB-Mw22T was 48.9 mol%, and its mean DNA–DNA hybridization values with Kangiella geojedonensis YCS-5T, Kangiella japonica JCM 16211T and Kangiella taiwanensis JCM 17727T were 14–28 %. Phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain BB-Mw22T is distinguishable from all recognized Kangiella species. On the basis of the data presented, strain BB-Mw22T is considered to represent a novel species of the genus Kangiella , for which the name Kangiella sediminilitoris sp. nov. is proposed. The type strain is BB-Mw22T ( = KCTC 23892T  = CCUG 62217T).
