Strains TU-16T and TU-18, two non-pigmented bacterial isolates with an optimum growth temperature of about 45 °C and an optimum pH of about 8·5–9·0, were recovered from the Furnas geothermal area on the Island of São Miguel in the Azores. Phylogenetic analysis of the 16S rRNA gene sequence of these strains indicated that they represent a novel species in a new genus of the phylum Betaproteobacteria. The major fatty acids of strains TU-16T and TU-18 were 16 : 0 and 18 : 1ω7c. Ubiquinone 8 was the major respiratory quinone and the major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The novel isolates were aerobic; thiosulfate was oxidized to sulfate in the presence of a metabolizable carbon source. The organism assimilated organic acids and amino acids, but did not assimilate carbohydrates or polyols. Based on phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strain TU-16T (=LMG 23030T=CIP 108724T) represents the type strain of a novel species in a new genus, Tepidicella xavieri gen. nov., sp. nov.

The 16S Rrna Gene

Two moderately halophilic Gram-negative bacteria were isolated from a sample taken from the brine–seawater interface of the Shaban Deep in the Red Sea. Phylogenetic analysis of the 16S rRNA gene sequence showed that these organisms represent a novel species of the genus Marinobacter. Cells of the new isolates formed non-pigmented colonies and were motile by means of a single polar flagellum. Strains SD-14BT and SD-14C grew optimally at 35–37 °C, in 5 % NaCl and at pH 7.5–8.0. The organisms were aerobic, but reduced nitrate to nitrogen under anaerobic conditions. Acid was produced from only a few carbohydrates. Ubiquinone 9 was the major respiratory quinone. The major fatty acids of strains SD-14BT and SD-14C were C16 : 0, C18 : 1 ω9c, summed feature 3 (C16 : 1 ω6c/C16 : 1 ω7c) and C12 : 0 3-OH. The DNA G+C contents were 55.9 and 55.7 mol%, respectively. On the basis of the phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strains SD-14BT and SD-14C represent a novel species of the genus Marinobacter, with the name Marinobacter salsuginis sp. nov. The type strain is strain SD-14BT (=DSM 18347T=LMG 23697T).

A bacterial isolate, with an optimum growth temperature of about 50 °C and an optimum pH for growth between 7.5 and 8.5, was recovered from a hot spring in the Furnas area of the Island of São Miguel in the Azores. The novel isolate is orange-pigmented, forms non-motile, rod-shaped cells that stain Gram-negative, is strictly aerobic, oxidase-positive and catalase-negative. The major fatty acids of strain TU-20T are 16 : 1ω6c, 17 : 0 iso 3-OH and 15 : 0 iso. Menaquinone 6 is the major respiratory quinone. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics, we describe a novel species of a novel genus represented by strain TU-20T ( = DSM 21410T  = LMG 24594T) for which we propose the name Schleiferia thermophila gen nov., sp. nov. We also propose the family Schleiferiaceae fam. nov. to accommodate this new genus.

Physiological And Biochemical Characteristics

Two bacterial isolates, designated AF-51T and AF-50, with an optimum growth temperature of about 45 °C and an optimum pH for growth between 6.0 and 6.5, were recovered from a hot spring in the Furnas, Área da Fonte 1825, on the Island of São Miguel in the Azores. Based on 16S rRNA gene sequence analysis, these strains were related most closely to the type strain of Hydrotalea flava at a pairwise similarity of 95.7 %. The two strains were orange-pigmented and formed non-motile, rod-shaped cells that stained Gram-negative and were aerobic and oxidase- and catalase-positive. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and iso-C16 : 0. The major respiratory quinone was menaquinone 7. Based on phylogenetic, physiological and biochemical characteristics, these strains from the Azores are considered to represent a single novel species of the genus Hydrotalea , for which the name Hydrotalea sandarakina sp. nov. is proposed. The type strain is AF-51T ( = DSM 23241T = LMG 25526T). We provide emended descriptions of the genus Hydrotalea and of H. flava to reflect new results obtained in this study.

A Gram-staining-positive, motile, rod-shaped, spore-forming bacterium, designated P9T, was isolated from soil in Portugal. This organism was aerobic and catalase- and oxidase-positive. It had an optimum growth temperature of about 35 °C and an optimum growth pH of about 8.0–8.5, and grew in medium with 0–9 % (w/v) NaCl. The cell-wall peptidoglycan was of the A1α type, with l-lysine as the diagnostic diamino acid. The major respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were anteiso-C15 : 0 (45.4 %), iso-C15 : 0 (22.0 %) and anteiso-C17 : 0 (11.2 %). The genomic DNA G+C content was about 39.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain P9T was most closely related to Jeotgalibacillus campisalis DSM 18983T (96.8 %) and Jeotgalibacillus marinus DSM 1297T (96.5 %). These two recognized species formed a coherent cluster with strain P9T that was supported by a bootstrap value of 99 %. On the basis of the phylogenetic analysis and physiological and biochemical characteristics, strain P9T ( = DSM 23228T = LMG 25523T) represents a novel species of the genus Jeotgalibacillus, for which the name Jeotgalibacillus soli sp. nov. is proposed.

Two red-pigmented isolates, designated RQ-33T and TU-13, were recovered from hot spring runoffs on the Island of São Miguel in the Azores, Portugal. These organisms have an optimum growth temperature of approximately 45 °C and an optimum pH for growth between 7.5 and 8.5. Based on 16S rRNA gene sequence analysis, the novel isolates were most closely related to the type strain of Cecembia lonarensis at 96.4 % pairwise similarity. Cells of the two isolates were non-motile, rod-shaped, Gram-stain-negative, strictly aerobic, and oxidase- and catalase-positive. The major fatty acids were iso-C15 : 0 and C15 : 0, phosphatidylethanolamine was the major polar lipid, and menaquinone 7 was the major respiratory quinone. Based on phylogenetic analyses, and physiological and biochemical characteristics, these isolates from the Azores represent a novel species of the genus Cecembia for which the name Cecembia calidifontis is proposed with strain RQ-33T ( = DSM 21411T = LMG 24596T) as the type strain. The description of the genus Cecembia is also emended.

A Gram-stain-negative, facultatively anaerobic, non-motile and pink-pigmented bacterium, designated strain HF08T, was isolated from marine sediment of the coast of Weihai, China. Cells were rod-shaped, and oxidase- and catalase-positive. The isolate grew optimally at 33 °C, at pH 7.5–8.0 and with 2–3 % (w/v) NaCl. The dominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C14 : 0. Menaquinone 7 (MK-7) was the major respiratory quinone and the DNA G+C content was 44.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate was a member of the class Bacteroidia, and shared 88–90 % sequence similarity with the closest genera Sunxiuqinia, Prolixibacter, Draconibacterium, Mariniphaga and Meniscus. Based on the phylogenetic and phenotypic evidence presented, a novel species in a new genus of the family Prolixibacteraceae is proposed, with the name Roseimarinus sediminis gen. nov., sp. nov.

Five cold-adapted bacteria belonging to the genus Mucilaginibacter were isolated from lichen and soil samples collected from Finnish Lapland and investigated in detail by phenotypic and phylogenetic analyses. Based on 16S rRNA gene phylogeny, the novel strains represent three new branches within the genus Mucilaginibacter. The strains were aerobic, chemo-organotrophic, non-motile rods and formed pigmented, smooth, mucoid colonies on solid media. The strains grew between 0 and 33 °C (optimum growth at 25 °C) and at pH 4.5–8.0 (optimum growth at pH 6.0). The main cellular fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1 ω7c/iso-C15 : 0 2-OH) and iso-C17 : 0 3-OH and the major respiratory quinone was MK-7. The DNA G+C contents were 44.0–46.5 mol%. Based on phylogenetic, phenotypic and chemotaxonomic data, the strains represent three novel species of the genus Mucilaginibacter for which the names Mucilaginibacter frigoritolerans sp. nov. (type strain FT22T =ATCC BAA-1854T =LMG 25359T), Mucilaginibacter lappiensis sp. nov. (type strain ANJLI2T =ATCC BAA-1855T =LMG 25358T) and Mucilaginibacter mallensis sp. nov. (type strain MP1X4T =ATCC BAA-1856T =LMG 25360T) are proposed.
