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).

A novel Gram-negative, rod-shaped, non-motile, non-sporulating bacterium, designated strain K1T, was isolated from an estuarine water sample collected from Kochi, Kerala, India. Colonies on marine agar were circular, 2.0–2.5 mm in diameter, shiny, yellow, translucent and convex with entire margins. Strain K1T was negative for ornithine decarboxylase, lysine decarboxylase, nitrate reduction and H2S production. The fatty acids were dominated by iso-branched components with a high abundance of iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH; MK-6 (64 %) and MK-7 (34 %) were found as major respiratory quinones; and phosphatidylethanolamine, two unidentified aminolipids, four unidentified phospholipids and two unidentified lipids were major polar lipids. The DNA G+C content of strain K1T was 46.1 mol%. 16S rRNA gene sequence analysis indicated that strain K1T was related most closely to the type strain of Zhouia amylolytica (pairwise sequence similarity of 93.0 %). Phylogenetic analysis showed that strain K1T formed a distinct branch within the family Flavobacteriaceae and clustered with the clade comprising species of the genera Zhouia , Coenonia and Capnocytophaga , being phylogenetically most closely related to the type strain of Zhouia amylolytica at a distance of 9.2 % (90.8 % similarity). Other species of the genera within the same clade were related to strain K1T at distances of 15.0–23.1 %. Based on phenotypic and chemotaxonomic characteristics and on phylogenetic inference, strain K1T is considered to represent a novel species of a new genus in the family Flavobacteriaceae , for which the name Imtechella halotolerans gen. nov., sp. nov. is proposed. The type strain of Imtechella halotolerans is K1T ( = MTCC 11055T = JCM 17677T).

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.

Faecal Samples

Four strains (9CBEGH2T, 9BBH35, 6BBH38 and 6EGH11) of Gram-stain-positive, obligately anaerobic, rod-shaped bacteria were isolated from faecal samples from healthy Japanese humans. The results of 16S rRNA gene sequence analysis indicated that the four strains represented members of the family Erysipelotrichaceae and formed a monophyletic cluster with ‘ Absiella argi ’ strain N6H1-5 (99.4% sequence similarity) and Eubacterium sp. Marseille-P5640 (99.3 %). Eubacterium dolichum JCM 10413T (94.2 %) and Eubacterium tortuosum ATCC 25548T (93.7 %) were located near this monophyletic cluster. The isolates, 9CBEGH2T, ‘ A. argi ’ JCM 30884 and Eubacterium sp. Marseille-P5640 shared 98.7–99.1% average nucleotide identity (ANI) with each other. Moreover, the in silico DNA–DNA hybridization (DDH) values among three strains were 88.4–90.6%, indicating that these strains represent the same species. Strain 9CBEGH2T showed 21.5–24.1 % in silico DDH values with other related taxa. In addition, the ANI values between strain 9CBEGH2T and other related taxa ranged from 71.2 % to 73.5 %, indicating that this strain should be considered as representing a novel species on the basis of whole-genome relatedness. Therefore, we formally propose a novel name for ‘ A. argi ’ strains identified because the name ‘ A. argi ’ has been effectively, but not validly, published since 2017. On the basis of the collected data, strain 9CBEGH2T represents a novel species of a novel genus, for which the name Amedibacterium intestinale gen. nov., sp. nov. is proposed. The type strain of A. intestinale is 9CBEGH2T (=JCM 33778T=DSM 110575T).

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).
