Emended Description

Three strains (14A-2-7T, 14A-3-1 and 14A-3) of Gram-stain-negative, prosthecate, motile bacteria were isolated from an algal medium supplemented with 10 mg ampicillin l−1 (w/v), in which the red alga Porphyra yezoensis had been cultured. Based on the 16S rRNA gene sequence analysis, the three isolates formed a cluster with the genus Algimonas of the family Hyphomonadaceae . The sequences of the three isolates had high similarity with those of Algimonas porphyrae 0C-2-2T (97.6 % similarity) and Litorimonas taeanensis G5T (95.6 % similarity). The DNA G+C contents of the three isolates ranged from 54.3 to 55.0 mol%, which were more similar to that of A. porphyrae 0C-2-2T (58.5 mol%) than to that of L. taeanensis G5T (47.1 mol%). The DNA–DNA relatedness showed that the three isolates were representatives of the same species (88.1–94.0 % relatedness) and that strain 14A-2-7T was a representative of a different species from A. porphyrae 0C-2-2T and L. taeanensis G5T (1.2–8.6 % relatedness). The phenotypic characteristics of strain 14A-2-7T differed by 20 results and 30 results from A. porphyrae 0C-2-2T and L. taeanensis G5T, respectively. The three isolates contained ubiquinone-10 as the predominant quinone and C18 : 1ω7c as the major fatty acid. Based on the polyphasic taxonomic analysis, the three isolates represent a novel species of the genus Algimonas , for which the name Algimonas ampicilliniresistens sp. nov. is proposed. The type strain is 14A-2-7T ( = LMG 26421T = NBRC 108219T). An emended description of the genus Algimonas is also proposed.

Three Gram-negative, stalked, motile bacteria, designated 0C-2-2T, 0C-17 and LNM-3, were isolated from the red alga Porphyra yezoensis. 16S rRNA gene sequence analysis revealed that the three novel strains belonged to the family Hyphomonadaceae , and were closely related to Litorimonas taeanensis G5T (96.5 % 16S rRNA gene sequence similarity) and Hellea balneolensis 26III/A02/215T (94.3 %). The DNA G+C contents of the novel isolates (58.5–60.2 mol%) were clearly distinguished from those of L. taeanensis G5T (47.1 mol%) and H. balneolensis DSM 19091T (47.9 mol%). The G+C content of L. taeanensis G5T obtained in this study was quite different from a previous report (63.6 mol%). DNA–DNA hybridization experiments showed that the novel strains constituted a single species. Eleven phenotypic features of the three isolates differed from those of both related genera. The predominant respiratory quinone was ubiquinone-10 and the major fatty acid was C18 : 1ω7c. On the basis of this polyphasic taxonomic analysis, the novel strains represent a novel genus and species, for which the name Algimonas porphyrae gen. nov., sp. nov. is proposed. The type strain of Algimonas porphyrae is 0C-2-2T ( = LMG 26424T  = NBRC 108216T).

Four novel strains isolated from the cloacal contents of snow finches (Montifringilla taczanowskii) were characterized as aerobic, Gram-stain-negative, slightly motile, and rod-shaped. Analysis of the 16S rRNA gene sequence revealed that strain CF-458T had the highest similarities of 96.9 and 96.4 % with Limnobaculum parvum HYN0051T and Pragia fontium DSM 5563T, while strain CF-1111T shared the highest similarities of 96.4 and 96.1 % with Pantoea rodasii LMG 26273T and Pectobacterium punjabense SS95T. Phylogenomic analysis showed the four isolates were separated into group Ⅰ (CF-458T and CF-917) and group Ⅱ (CF-1111T and CF-509), and clustered independently in the vicinity of the genera Limnobaculum and Pragia . Summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c, 23.9 and 17.2 %, respectively), C16 : 0 (21.8 and 22.1 %, respectively) and C14 : 0 (10.6 and 17.7 %, respectively) were the common major fatty acids, and summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c, 12.3 %) was also a major fatty acid for strain CF-458T while cyclo-C17 : 0 (13.1%) was for strain CF-1111T. Both had Q-8 as the sole quinone and contained phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol as the major polar lipids. The DNA G+C content of strains CF-458T and CF-1111T was 45.7 and 45.4 mol%, respectively. Based on taxonomic position in the phylogenomic tree and phenotypic properties, two novel species of a new genus within the family Budviciaceae are thus proposed, with the name Jinshanibacter gen. nov., zhutongyuii sp. nov. (type strain CF-458T=CGMCC 1.16483T=GDMCC 1.1586T=JCM 33489T) and Jinshanibacter xujianqingii sp. nov. (type strain CF-1111T=CGMCC 1.16786T=GDMCC 1.1587T=JCM 33490T), respectively.

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 strictly anaerobic, mesophilic, carbohydrate-fermenting, hydrogen-producing bacterium, designated strain RL-CT, was isolated from a reed swamp in China. Cells were Gram-stain-negative, catalase-negative, non-spore-forming, non-motile rods measuring 0.7–1.0 µm in width and 3.0–8.0 µm in length. The optimum temperature for growth of strain RL-CT was 37 °C (range 25–40 °C) and pH 7.0–7.5 (range pH 5.7–8.0). The strain could grow fermentatively on yeast extract, tryptone, arabinose, glucose, galactose, mannose, maltose, lactose, glycogen, pectin and starch. The main end products of glucose fermentation were acetate, H2 and CO2. Organic acids, alcohols and amino acids were not utilized for growth. Yeast extract was not required for growth; however, it stimulated growth slightly. Nitrate, sulfate, sulfite, thiosulfate, elemental sulfur and Fe(III) nitrilotriacetate were not reduced as terminal electron acceptors. Aesculin was hydrolysed but not gelatin. Indole and H2S were produced from yeast extract. The G+C content of the genomic DNA was 51.2 mol%. The major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and C16 : 0. The most abundant polar lipid of strain RL-CT was phosphatidylethanolamine. 16S rRNA gene sequence analysis revealed that the isolate belongs to the uncultured Blvii28 wastewater-sludge group (http://www.arb-silva.de/) in the family Rikenellaceae of the phylum Bacteroidetes, and shared low sequence similarities with the related species Alistipes shahii WAL 8301T (81.8 %), Rikenella microfusus ATCC 29728T (81.7 %) and Anaerocella delicata WN081T (80.9 %). On the basis of these data, a novel species in a new genus of the family Rikenellaceae is proposed, Acetobacteroides hydrogenigenes gen. nov., sp. nov. The type strain of the type species is RL-CT ( = JCM 17603T = DSM 24657T = CGMCC 1.5173T).

Strains of the recently proposed species Bacteroides chinchillae share more than 99.4 % 16S rRNA gene sequence similarity with the type strain of Bacteroides sartorii although these two species do not appear to be similar from their published descriptions. The aim of this study was to perform phenotypic and genetic analyses of both species to clarify their taxonomic position. B. chinchillae JCM 16497T exhibited high hsp60 gene sequence similarity with B. sartorii JCM 17136T (100 %) as well as B. chinchillae JCM 16498 (100 %). The hsp60 gene sequence analysis and levels of DNA–DNA relatedness observed demonstrated B. sartorii JCM 17136T, B. chinchillae JCM 16497T, and B. chinchillae JCM 16498 are members of a single species. Based on these data, we propose Bacteroides chinchillae as a later heterotypic synonym of Bacteroides sartorii . An emended description of B. sartorii is provided.
