Terrestrial Hot Spring

An aerobic, motile, moderately thermophilic rod, designated strain CLWT, was isolated from a terrestrial hot spring in an exposition garden in Xiamen City, Fujian Province, the People’s Republic of China. Strain CLWT formed beige, dry colonies on solid 2216E medium and flocks in liquid medium. Cells were Gram-stain-negative, short rods (1.0–3.0 µm long and 0.4–0.6 µm wide) with six or more polar flagella. The temperature and pH for growth of strain CLWT were 28–65 °C (optimum, 50–58 °C) and pH 5.5–9.5 (optimum, pH 6.0–8.0). Growth occurred in the presence of 0.3–6.0 % NaCl (optimum 2.5–4.5 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that the closest relative of the isolate was Amaricoccus kaplicensis Ben 101T (94.3 % sequence similarity). The DNA G+C content of strain CLWT was 72.2 mol%. The respiratory quinone was ubiquinone 10. The predominant polar lipids consisted of phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids (>10 %) were summed feature 8 (consisting of C18 : 1ω7c and/or C18 : 1ω6c), C18 : 1ω7c 11-methyl and C18 : 0. Based on phylogenetic, physiological and biochemical data and DNA G+C content, strain CLWT is considered to represent a novel species of a new genus in the family Rhodobacteraceae , for which the name Pleomorphobacterium xiamenense gen. nov., sp. nov. is proposed. The type strain of the type species is CLWT ( = LMG 26245T = CGMCC 1.10808T = MCCC 1A06272T).

Terrestrial Hot Spring

An anaerobic, moderately thermophilic, terminal-spore-forming bacterium, designated strain USBA AT, was isolated from a terrestrial hot spring located at an altitude of 2683 m in the Andean region of Colombia (04° 50′ 14.0″ N 75° 32′ 53.4″ W). Cells of strain USBA AT were Gram-stain-positive, straight to slightly curved rods (0.9×2.5 µm), that were arranged singly or in pairs, and were motile by means of flagella. Growth occurred at 37–55 °C and pH 6.0–8.0, with a doubling time of 2 h under the optimal conditions (50 °C and pH 7.0). Glucose fermentation in strain USBA AT required yeast extract or peptone (each at 0.2 %, w/v). The novel strain fermented sugars, amino acids, Casamino acids, propanol, propionate, starch and dextrin, but no growth was observed on galactose, lactose, xylose, histidine, serine, threonine, benzoate, butyrate, lactate, pyruvate, succinate, methanol, ethanol, glycerol, casein, gelatin or xylan. The end products of glucose fermentation were formate, acetate, ethanol and lactate. Strain USBA AT did not grow autotrophically (with CO2 as carbon source and H2 as electron donor) and did not reduce thiosulfate, sulfate, elemental sulfur, sulfite, vanadium (V) or Fe (III) citrate. Growth of strain USBA AT was inhibited by ampicillin, chloramphenicol, kanamycin, penicillin and streptomycin (each at 10 µg ml−1). The predominant fatty acids were iso-C15 : 0, C16 : 0 and iso-C17 : 0 and the genomic DNA G+C content was 32.6 mol%. 16S rRNA gene sequence analysis indicated that strain USBA AT belonged in the phylum Firmicutes and that its closest relative was Caloramator viterbiensis JW/MS-VS5T (95.0 % sequence similarity). A DNA–DNA relatedness value of only 30 % was recorded in hybridization experiments between strain USBA AT and Caloramator viterbiensis DSM 13723T. Based on the phenotypic, chemotaxonomic and phylogenetic evidence and the results of the DNA–DNA hybridization experiments, strain USBA AT represents a novel species of the genus Caloramator , for which the name Caloramator quimbayensis sp. nov. is proposed. The type strain is USBA AT ( = CMPUJ U833T  = DSM 22093T).

A strictly anaerobic, moderately thermophilic, halotolerant rod, designated BELH25T, was isolated from a water sample of a Tunisian hot spring. Cells were non-motile, 2–6 µm long and 0.4–0.6 µm wide, appearing singly or in pairs. The isolate grew at 45–70 °C (optimum 55 °C), at pH 6.2–8.0 (optimum pH 7.0) and with 0–4 % NaCl (optimum 0–2.0 %). Sulfate, thiosulfate, elemental sulfur, sulfite, nitrate and nitrite were not used as terminal electron acceptors. Strain BELH25T used cellobiose, fructose, galactose, glucose, maltose, mannose, sucrose, starch and yeast extract as electron donors. The main fermentation products from glucose metabolism were formate, acetate, ethanol and CO2. The predominant cellular fatty acids were iso-C15 : 0, iso-C17 : 0 and anteiso-C15 : 0. The DNA G+C content was 37.2 mol%. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain BELH25T was most closely related to Caloramator viterbiensis JW/MS-VS5T and Fervidicella metallireducens AeBT (92.2 and 92.1 % sequence similarity, respectively), and the isolate was positioned approximately equidistantly between these genera. Based on phenotypic, phylogenetic and chemotaxonomic characteristics, strain BELH25T is proposed to be a member of a novel species of a novel genus within the order Clostridiales , family Clostridiaceae , for which the name Fonticella tunisiensis gen. nov., sp. nov. is proposed. The type strain of the type species is BELH25T ( = DSM 24455T = JCM 17559T).

An aerobic, motile, moderately thermophilic, rod-shaped bacterium, strain YBY-7T, was isolated from a terrestrial hot spring of a garden exhibition located in Xiamen City, Fujian Province, People’s Republic of China. Cells of strain YBY-7T were Gram-negative, irregular rods, 2–6 µm long and 0.4–0.6 µm wide, with polar flagella, and the organism formed beige colonies. The temperature and pH ranges for growth of strain YBY-7T were 28–65 °C (optimum 50–58 °C) and pH 6.5–9.5 (optimum pH 7.5–8.5). Growth occurred in the presence of 5.5 % NaCl (optimum 3.0 %). Phylogenetic analysis based on the 16S rRNA gene sequence revealed that Albidovulum inexpectatum FRR-10T was its closest neighbour (95.9 % similarity). Ubiquinone (Q-10) was the sole respiratory quinone and the DNA G+C content of strain YBY-7T was 70.6 mol%. The predominant polar lipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids were C18 : 1ω7c (29.3 %), C19 : 0 cyclo ω8c (25.6 %), C18 : 0 (23.6 %) and C16 : 0 (9.6 %). Based on its physiological characteristics and our phylogenetic analysis, we propose that strain YBY-7T represents a novel species of the genus Albidovulum , for which the name Albidovulum xiamenense sp. nov. is proposed, with the type strain YBY-7T ( = MCCC 1A06317T  = CGMCC 1.10789T  = LMG 26247T).

A thermophilic, aerobic, Gram-stain-negative, filamentous bacterium, strain PRI-4131T, was isolated from an intertidal hot spring in Isafjardardjup, NW Iceland. The strain grew chemo-organotrophically on various carbohydrates. The temperature range for growth was 40–65 °C (optimum 55 °C), the pH range was pH 6.5–9.0 (optimum pH 7.0) and the NaCl range was 0–3 % (w/v) (optimum 0.5 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain PRI-4131T represented a distinct lineage within the class Caldilineae of the phylum Chloroflexi. The highest levels of sequence similarity, about 91 %, were with Caldilinea aerophila STL-6-O1T and Caldilinea tarbellica D1-25-10-4T. Fermentative growth was not observed for strain PRI-4131T, which, in addition to other characteristics, distinguished it from the two Caldilinea species. Owing to both phylogenetic and phenotypic differences from the described members of the class Caldilineae , we propose to accommodate strain PRI-4131T in a novel species in a new genus, Litorilinea aerophila gen. nov., sp. nov. The type strain of Litorilinea aerophila is PRI-4131T ( = DSM 25763T  = ATCC BAA-2444T).
