A red-pigmented, Gram-reaction-negative, aerobic bacterial strain, designated No.164T, was isolated from sediment sample from the alkaline Lake Elmenteita located in the Kenyan Rift Valley. Results of 16S rRNA gene sequence analysis indicated that the isolate represented a member of the genus Belliella , with the highest sequence similarity (97 %) to Belliella pelovolcani DSM 46698T. Optimal growth temperature was 30–35 °C, at pH 7.0–12.0 in the presence of 0–4 % (w/v) NaCl. Flexirubins were absent. The respiratory menaquinone (MK-7), predominant cellular fatty acids (iso-C15 : 0, anteiso-C15 : 0 and a mixture of C16 : 1ω7c and/or iso-C15 : 0 2-OH) and DNA G+C content (38.1 mol%) of strain No.164T were consistent with those of other members of the genus Belliella . The polar lipids consisted of phosphatidylethanolamine, eight unspecified lipids and one unspecified phospholipid. Several phenotypic characteristics can be used to differentiate this isolate from those of other species of the genus Belliella . The results of polyphasic analyses presented in this study indicated that this isolate should be classified as representing a novel species of the genus Belliella . The name Belliella kenyensis sp. nov. is therefore proposed; the type strain is strain No.164T ( = DSM 46651T = CECT 8551T).

A Gram-stain-negative, rod-shaped, orange-coloured, catalase- and oxidase-positive, non-motile bacterium, designated strain 92VT, was isolated from the marine sponge Amphilectus fucorum, collected from Lough Hyne, County Cork, Ireland. 16S rRNA gene sequence analysis revealed that strain 92VT clustered with members of the family Flavobacteriaceae , the closest member being Aquimarina latercula NCIMB 1399T, with a gene sequence similarity of 97.5 %. Strain 92VT required seawater for growth with optimal growth occurring at 25 °C, at pH 6–7 and with 3 % (w/v) NaCl. MK-6 was the sole respiratory quinone present and the major fatty acids were iso-C17 : 0 3-OH, iso-C15 : 0, iso-C17 : 1ω9c and iso-C15 : 0 3-OH. The DNA G+C content was 36.1 mol%. Combined phenotypic differences and phylogenetic analysis indicate that strain 92VT represents a novel species of the genus Aquimarina , for which the name Aquimarina amphilecti sp. nov. is proposed. The type strain is 92VT ( = NCIMB 14723T = DSM 25232T).

An aerobic, Gram-stain-negative, agarolytic rod-shaped bacterium, designated KMM 9504T, was isolated from a sediment sample collected from the seashore of the Sea of Japan. Comparative 16S rRNA gene sequence analysis showed that strain KMM 9504T belonged to the genus Simiduia as it was most closely related to Simiduia areninigrae KCTC 23293T (97.3 % sequence similarity). Strain KMM 9504T was characterized by the major ubiquinone Q-8, and by the predominance of C16 : 1ω7c, C17 : 1ω8c, followed by C16 : 0, C15 : 0, C17 : 0 and C12 : 1 in its fatty acid profile. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminophospholipid, an unknown aminolipid, unknown phospholipids, and unknown lipids. Based on the distinctive phenotypic characteristics, phylogenetic analysis and DNA–DNA hybridization results, it is concluded that strain KMM 9504T represents a novel species of the genus Simiduia , for which the name Simiduia litorea sp. nov. is proposed. The type strain of the species is strain KMM 9504T ( = NRIC 0917T = JCM 19759T).

An aerobic, Gram-stain-negative, yellow-pigmented, non-motile, rod-shaped bacterium designated strain KMM 9005T was isolated from a sediment sample collected from the Sea of Japan seashore. Comparative 16S rRNA gene sequence analysis showed that strain KMM 9005T belonged to the genus Luteimonas and was most closely related to Luteimonas cucumeris KCTC 23627T (96.5 % sequence similarity) and Luteimonas aquatica LMG 24212T (96.1 % sequence similarity). Strain KMM 9005T was characterized by the presence of thin fimbriae, the major ubiquinone Q-8, by the predominance of iso-C17 : 1 followed by iso-C16 : 0, iso-C15 : 0 and iso-C17 : 0 in its fatty acid profile, weak hydrolytic capacity and the inability to assimilate most organic substrates. Based on these distinctive phenotypic characteristics and phylogenetic analysis, strain KMM 9005T represents a novel species of the genus Luteimonas , for which the name Luteimonas vadosa sp. nov. is proposed. The type strain is KMM 9005T ( = NRIC 0881T = JCM 18392T).

A Gram-stain-positive thermophilic bacterium, designated strain Nis3T, was isolated from compost. The strain grew at 23–57 °C (optimum, 50 °C); no growth was observed below 15 or above 60 °C. The pH range for growth was 5.9–8.8 (optimum, 7.0); no growth was observed below pH 5.4 or above pH 9.3. The DNA G+C content of strain Nis3T was 63.4 mol%. The dominant quinone type was ubiquinone Q-10. The major fatty acids were C18 : 1ω7c, C19 : 0ω8c cyclo and C18 : 0. The polar lipids comprised phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylmonomethylethanolamine, an unknown glycolipid and a ninhydrin-positive phospholipid. 16S rRNA gene sequence analysis assigned this bacterium to the family Phyllobacteriaceae in the Alphaproteobacteria but it shared less than 95.2 % sequence similarity with other members of the family. The chemotaxonomic and phenotypic characteristics of strain Nis3T differed in some respects from those of members of the family Phyllobacteriaceae . Therefore, strain Nis3T is considered to represent a novel species of a new genus in the family Phyllobacteriaceae , for which the name Thermovum composti gen. nov., sp. nov. is proposed. The type strain is Nis3T ( = JCM 17863T = KCTC 23707T).

A novel Gram-negative, rod-shaped, non-motile bacterium, designated strain N1T, was isolated from a marine water sample collected from the sea shore, Bay of Bengal, Visakhapatnam, India. The strain was positive for starch hydrolysis, nitrate reduction and ornithine decarboxylase activities and negative for citrate utilization, urease, oxidase, catalase and DNase activities. The predominant fatty acids were C16 : 0 3-OH, iso-C15 : 0, iso-C15 : 0 3-OH, iso-C17 : 0 3-OH, anteiso-C15 : 0, C16 : 0, C15 : 0 3-OH, and C16 : 1ω7c and/or iso-C15 : 0 2-OH (summed feature 3). Strain N1T contained menaquinone 6 (MK-6) as the sole respiratory quinone. The only polyamine was homospermidine and the major polar lipids were phosphatidylethanolamine (PE), three unidentified aminolipids (AL1–AL3) and two unidentified lipids (L1, L2). The DNA G+C content of the strain was 36.3 mol%. 16S rRNA gene sequence analysis indicated that strain N1T was a member of the genus Flavobacterium and closely related to Flavobacterium resistens with pairwise sequence similarity of 96.5 %. Phylogenetic analysis showed that strain N1T clustered with Flavobacterium glycines and Flavobacterium daejeonense with a distance of 4.8 and 6.0 % (95.2 and 94.0 % similarity), respectively. Based on the phenotypic characteristics and on phylogenetic inference, strain N1T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium nitratireducens sp. nov. is proposed.

A Gram-negative, orange-pigmented, rod-shaped, motile and aerobic bacterial strain designated DM9T was isolated from hexachlorocyclohexane (HCH)-contaminated soil (Lucknow, India) and its taxonomic position was determined using a polyphasic approach. 16S rRNA gene sequence analysis showed that the isolate belonged to the phylum Bacteroidetes and confirmed its placement in the genus Pontibacter , with sequence similarity ranging from 93.92 to 96.21 % with other members of the genus Pontibacter . The major cellular fatty acids of the novel strain were iso-C17 : 0 3-OH (6.00 %), iso-C15 : 0 (21.54 %) and summed feature 4 (comprising C17 : 1 iso I/anteiso B; 32.3 %). The polar lipid profile of strain DM9T showed the presence of phosphatidylethanolamine, an unidentified aminophospholipid, two unknown aminolipids and four unknown polar lipids. Strain DM9T contained MK-7 as the predominant menaquinone and its DNA G+C content was 49.2 mol%. sym-Homospermidine was the major polyamine observed in the cell. The results obtained on the basis of phenotypic characteristics, phylogenetic analysis, biochemical and physiological tests clearly distinguished DM9T from closely related members of the genus Pontibacter . It is proposed that DM9T represents a novel species, Pontibacter lucknowensis sp. nov.; the type strain is DM9T ( = CCM 7955T = MTCC 11079T).

Strain HNM0947T, representing a novel actinobacterium, was isolated from the coral Galaxea astreata collected from the coast of Wenchang, Hainan, China. The strain was found to have morphological and chemotaxonomic characteristics consistent with the genus Nocardiopsis . The organism formed abundant fragmented substrate mycelia and aerial mycelia which differentiated into non-motile, rod-shaped spores. Whole-cell hydrolysates contained meso-diaminopimelic acid and no diagnostic sugars. The major menaquinones were MK-10(H8), MK-10(H6) and MK-10(H4). The major phospholipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major fatty acids were iso-C16:0, anteiso-C17:0, C18:0, C18:0 10-methyl (TBSA) and anteiso-C15:0. The G+C content was 71.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain HNM0947T belonged to the genus Nocardiopsis and shared highest sequence similarity to Nocardiopsis salina YIM 90010T (98.8%), Nocardiopsis xinjiangensis YIM 90004T(98.5%) and Nocardiopsis kunsanensis DSM 44524T (98.3%). The strain HNM0947T was distinguished from its closest type strain by low average nucleotide identity (90.8%) and dDDH values (60.4%) respectively. Based on genotypic, chemotaxonomic and phenotypic characteristics, it was concluded that strain HNM0947T represents a novel species of the genus Nocardiopsis whose name was proposed as Nocardiopsis coralli sp. nov. The type strain was HNM0947T (=CCTCC AA 2020015 T=KCTC 49525 T).

A novel mesophilic, aerotolerant anaerobic bacterium, designated JN-18T, was isolated from the pit mud of a strong aromatic Chinese liquor. According to a 16S rRNA gene sequence analysis, it had the highest sequence similarity to Aminipila butyrica DSM 103574T (95.69%). The G+C content of its genomic DNA was 43.39 mol%. The cells were Gram-stain-negative, slightly curved rods with flagella. Optimum growth was observed at 37 °C, pH 6.5 and without extra addition of NaCl. Strain JN-18Tutilized amino acids (l-alanine, l-arginine, l-asparagine, l-lysine, l-methionine, l-serine and l-threonine), malate and pyruvate, and used l-arginine and l-lysine to produce acetate, butyrate, H2, and CO2. The major cellular fatty acids of strain JN-18T were C14:0, C16:0 DMA and C18:1 cis-9 DMA. The carbohydrate composition of the cell wall predominantly included galactose, glucose and rhamnose. Based on its phylogenetic, phenotypic, physiological and biochemical characteristics, strain JN-18T was classified as a representative of a novel species within the genus Aminipila , for which the name Aminipila luticellarii sp. nov. is proposed. The type strain is JN-18T (=CCAM 412T=JCM 39126T).

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).

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).
