A novel bacterial strain designated P-1T was isolated from the trunk surface of a Japanese oak (Quercus crispula) growing in the Shirakami Mountains in Japan. Cells of strain P-1T were Gram-stain-negative, ellipsoidal endospore-forming, aerobic, slightly acidophilic rods, 0.8×2–5 µm, and motile by means of peritrichous flagella. Various carbohydrates could be used as growth substrates, but none of the organic acids tested were used. The major cellular fatty acid was anteiso-C15 : 0, which accounted for 64.2 % of the total fatty acids. The major respiratory quinone was menaquinone 7 (MK-7). Strain P-1T contained phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine, four unidentified aminolipids, an unidentified phospholipid and two unidentified polar lipids. Strain P-1T shared the highest 16S rRNA gene sequence similarity with Paenibacillus pini S22T (96.6 %), followed by Paenibacillus chibensis JCM 9905T (96.1 %) and Paenibacillus anaericanus MH21T (95.9 %). The DNA G+C content was 43.9 mol%. These data indicate that strain P-1T represents a novel species within the genus Paenibacillus , for which we propose the name Paenibacillus shirakamiensis sp. nov. The type strain is P-1T (NBRC 109471T = DSM 26806T = KCTC 33126T = CIP 110571T).

A Gram-stain-negative, rod-shaped and aerobic bacterial strain, named Ery12T, was isolated from the overlying water of the Lau Basin in the Southwest Pacific Ocean. Strain Ery12T showed high 16S rRNA gene sequences similarity to Tsuneonella flava MS1-4T (99.9 %), T. mangrovi MCCC 1K03311T (98.1 %), Altererythrobacter ishigakiensis NBRC 107699T (97.3 %) and exhibited ≤97.0 % sequence similarity with other type strains of species with validly published names. Growth was observed in media with 0–10.0 % NaCl (optimum 0–1.0 %, w/v), pH 5.0–9.5 (optimum 6.0–7.0) and 10–42 °C (optimum 30–37 °C). The predominant respiratory quinone was ubiquinone 10 (Q-10). The major cellular fatty acid was summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c). The major polar lipids were sphingoglycolipid, phosphatidyglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, three unidentified glycolipids, one unidentified aminoglycolipid and one unidentified lipid. The DNA G+C content was 60.8 %. The ANI and in silico DDH values between strain Ery12T and the type strains of its closely related species were 71.0- 91.8 % and 19.5- 44.6 %, respectively. According to the phenotypic, chemotaxonomic, phylogenetic and genomic data, strain Ery12T represents a novel species of the genus Tsuneonella , for which the name Tsuneonella suprasediminis is proposed. The type strain is Ery12T (=CGMCC 1.16500 T=MCCC 1A04421T=KCTC 62388T). We further propose to reclassify Altererythrobacter rhizovicinus and Altererythrobacter spongiae as Pelagerythrobacter rhizovicinus comb. nov. and Altericroceibacterium spongiae comb. nov., respectively.

Five phytopathogenic bacterial strains, MAFF 301449T, MAFF 301450, MAFF 301451, MAFF 301452, and MAFF 301453, which were isolated from bud blight lesions of cyclamen (Cyclamen persicum Mill.) in Miyagi, Japan, were subjected to polyphasic taxonomic characterisation. The cells were Gram-reaction-negative, aerobic, non-spore-forming, motile with one to five polar flagella, and rod-shaped. Analysis of 16S rRNA gene sequences showed that they belong to the genus Pseudomonas , with Pseudomonas extremaustralis 14-3T (99.79 % sequence similarity), Pseudomonas trivialis DSM 14937T (99.79 %), Pseudomonas poae DSM 14936T (99.72 %), and Pseudomonas antarctica CMS 35T (99.72 %) as their relatives. The genomic DNA G+C content was 60.3 mol% and the major fatty acids (>5 % of the total fatty acids) were C16 : 0, summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c), summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c), and C17 : 0 cyclo. Phylogenetic analysis using the rpoD gene sequences and phylogenomic analyses based on the whole genome sequences demonstrated that the strains are members of the Pseudomonas fluorescens subgroup, but form a monophyletic and robust clade separated from their relatives. Average nucleotide identity and digital DNA–DNA hybridisation analyses with the closely related Pseudomonas species corroborated their novel species status. The strains were differentiated from their relatives by phenotypic characteristics, pathogenicity towards cyclamen, cellular fatty acid composition, and whole-cell MALDI-TOF mass spectrometry profiles. Based on the phenotypic, chemotaxonomic, and genotypic data obtained, we conclude that the strains represent a novel Pseudomonas species, for which we propose the name Pseudomonas cyclaminis sp. nov.; the type strain is MAFF 301449T (=ICMP 23720T).
