Hydroxyphenylacetic Acid

Strain SK9K4T, which is a strictly anaerobic, non-motile, non-sporulating, Gram-stain-positive, saccharolytic coccobacillus, was isolated from pig faeces. SK9K4T metabolized indol-3-acetic acid to 3-methylindole (skatole), which is the main contributor to boar taint; it also produced 4-methylphenol (p-cresol) from p-hydroxyphenylacetic acid. Phylogenetic analyses, based on 16S rRNA gene sequences, revealed that the isolate represented a new lineage within the genus Olsenella of the family Atopobiaceae . Strain SK9K4T was most closely related to the type strains of the three species of the genus Olsenella with validly published names; Olsenella profusa DSM 13989T (93.6 %), Olsenella uli DSM 7084T (93.5 %) and Olsenella umbonata DSM 22620T (92.7 %). DNA–DNA relatedness values of strain SK9K4T with O. profusa , O. uli and O. umbonata were 28.3 %, 69.1 % and 27.2 %, respectively. The genomic DNA G+C content was 62.1 mol% and the major cellular fatty acids (constituting >10 % of the total) were C14 : 0 and C18 : 1ω9c. The major end product of glucose fermentation was lactic acid, with minor amounts of acetic acid and formic acid; no H2 was produced. Discrepancies in the fatty acid profiles, the MALDI-TOF mass spectra of cell extracts and the physiological and biochemical characteristics differentiated strain SK9K4T from other species of the genus Olsenella and indicate that the isolate represents a novel species within this genus. The name Olsenella scatoligenes sp. nov., is proposed and the type strain is SK9K4T ( = JCM 19907T = DSM 28304T).

A strictly anaerobic, mesophilic, sulfate-reducing bacterial strain (DST), isolated from river sediment contaminated with volatile organic compounds, was characterized phenotypically and phylogenetically. Cells were Gram-reaction-negative, non-motile short rods. For growth, optimum NaCl concentration was 0.9 g l−1, optimum temperature was 30 °C and optimum pH was 7.2. Strain DST utilized phenol, benzoate, 4-hydroxybenzoate, 4-methylphenol, 4-chlorophenol, acetate, butyrate and pyruvate as electron donors for sulfate reduction. Electron donors were completely oxidized. Strain DST did not utilize sulfite, thiosulfate or nitrate as electron acceptors. The genomic DNA G+C content of strain DST was 58.9 mol%. Major cellular fatty acids were iso-C14 : 0, anteiso-C15 : 0 and C18 : 1ω7c. Phylogenetic analyses based on the 16S rRNA gene indicated its closest relatives were strains of Desulfobacterium anilini (about 98–99 % sequence similarity) but the DNA–DNA hybridization value with Desulfobacterium anilini Ani1T was around 40 %. Although strain DST and its relatives shared most phenotypic and chemotaxonomic characteristics, the utilization of 4-chlorophenol, the range of electron acceptors and the optimum growth conditions differed. Strain DST is closely related to strains of Desulfobacterium anilini , but constitutes a different species within the genus. Based on phylogeny, phenotypic characteristics and chemotaxonomic characteristics, strain DST and Desulfobacterium anilini were clearly different from strains of other species of the genus Desulfobacterium . We thus propose the reclassification of Desulfobacterium anilini within a new genus, Desulfatiglans gen. nov., as Desulfatiglans anilini comb. nov. We also propose Desulfatiglans parachlorophenolica sp. nov. to accommodate strain DST. The type strain is DST ( = JCM 19179T = DSM 27197T).

A novel Gram-positive, non-motile, non-flagellated, strictly anaerobic, non-spore-forming and dumbbell-shaped, coccoid- or chain-shaped bacterium, designated strain LZLJ-3T, was isolated from a mud fermentation cellar which has been used for the production of Chinese strong-flavour liquor for over 100 years. Strain LZLJ-3T grew at 20–40 °C (optimum, 37 °C), at pH 6.0–8.0 (optimum, pH 8.0) and with NaCl concentrations up to 1 % (w/v; optimum, 0 %). Phylogenetic trees established based on 16S rRNA gene sequences showed that strain LZLJ-3T belonged to the genus Blautia of the family Lachnospiraceae, with the highest sequence similarity to Blautia stercoris GAM6-1T (91.7 %) and Blautia faecicola KGMB01111T (91.7 %). Comparative genome analysis showed that the orthologous average nucleotide identity (OrthoANI) and genome-to-genome distance (GGD) values between strain LZLJ-3T and B. stercoris GAM6-1T were respectively 69.1 and 22.9 %; the OrthoANI and GGD values between strain LZLJ-3T and B. faecicola KGMB01111T were respectively 70.86 and 36 % . The DNA G+C content of strain LZLJ-3T genome was 42.1 mol%. The predominant celluar fatty acids (>10 %) of strain LZLJ-3T were C16 : 0 FAME (27.9 %), C14 : 0 FAME (17.6 %) and C16 : 0 DMA (13.0 %). Arabinose, glucose and maltose could be utilized by strain LZLJ-3T as sole carbon sources for growth, with weak utilization of raffinose and l-fucose. API ZYM analysis gave positive reactions with α-galactosidase, β-galactosidase, α-glucosidase and β-glucosidase. The major end product of glucose fermentation was acetic acid. Based on the results of phenotypic, genotypic and phylogenetic analyses, strain LZLJ-3T is considered to represent a novel species of Blautia , for which the name Blautia liquoris sp. nov. is proposed. The type strain is LZLJ-3T (=KCTC 25163T=CGMCC 1.5299T=JCM 34225T).

A Genome

A Gram-stain-negative, strictly anaerobic, non-motile, rod-shaped bacterium, designated SFB93T, was isolated from the intertidal sediments of South San Francisco Bay, located near Palo Alto, CA, USA. SFB93T was capable of acetylenotrophic and diazotrophic growth, grew at 22–37 °C, pH 6.3–8.5 and in the presence of 10–45 g l−1 NaCl. Phylogenetic analyses based on 16S rRNA gene sequencing showed that SFB93T represented a member of the genus Syntrophotalea with highest 16S rRNA gene sequence similarities to Syntrophotalea acetylenica DSM 3246T (96.6 %), Syntrophotalea carbinolica DSM 2380T (96.5 %), and Syntrophotalea venetiana DSM 2394T (96.7 %). Genome sequencing revealed a genome size of 3.22 Mbp and a DNA G+C content of 53.4 %. SFB93T had low genome-wide average nucleotide identity (81–87.5 %) and <70 % digital DNA–DNA hybridization value with other members of the genus Syntrophotalea . The phylogenetic position of SFB93T within the family Syntrophotaleaceae and as a novel member of the genus Syntrophotalea was confirmed via phylogenetic reconstruction based on concatenated alignments of 92 bacterial core genes. On the basis of the results of phenotypic, genotypic and phylogenetic analyses, a novel species, Syntrophotalea acetylenivorans sp. nov., is proposed, with SFB93T (=DSM 106009T=JCM 33327T=ATCC TSD-118T) as the type strain.

Mid Atlantic Ridge

A coccoid-shaped, strictly anaerobic, hyperthermophilic and piezophilic organoheterotrophic archaeon, strain Iri35cT, was isolated from a hydrothermal chimney rock sample collected at a depth of 2300 m at the Mid-Atlantic Ridge (Rainbow vent field). Cells of strain Iri35cT grew at NaCl concentrations ranging from 1–5 % (w/v) (optimum 2.0 %), from pH 5.0 to 9.0 (optimum 7.0–7.5), at temperatures between 50 and 90 °C (optimum 75–80 °C) and at pressures from 0.1 to at least 50 MPa (optimum: 10–30 MPa). The novel isolate grew on complex organic substrates, such as yeast extract, tryptone, peptone or beef extract, preferentially in the presence of elemental sulphur or l-cystine; however, these molecules were not necessary for growth. Its genomic DNA G+C content was 54.63 mol%. The genome has been annotated and the metabolic predictions are in accordance with the metabolic characteristics of the strain and of Thermococcales in general. Phylogenetic analyses based on 16S rRNA gene sequences and concatenated ribosomal protein sequences showed that strain Iri35cT belongs to the genus Thermococcus, and is closer to the species T. celericrescens and T. siculi . Average nucleotide identity scores and in silico DNA–DNA hybridization values between the genome of strain Iri35cT and the genomes of the type species of the genus Thermococcus were below the species delineation threshold. Therefore, and considering the phenotypic data presented, strain Iri35cT is suggested to represent a novel species, for which the name Thermococcus camini sp. nov. is proposed, with the type strain Iri35cT (=UBOCC M-2026T=DSM 111003T).

Chlorinated Alkanes

Two strictly anaerobic bacterial strains, designated IP3-3T and SBP-1, were isolated from groundwater contaminated by chlorinated alkanes and alkenes at a Superfund Site located near Baton Rouge, Louisiana (USA). Both strains reductively dehalogenate a variety of polychlorinated aliphatic alkanes, including 1,2-dichloroethane, 1,2-dichloropropane, 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane and 1,2,3-trichloropropane, when provided with hydrogen as the electron donor. To clarify their taxonomic position, strains IP3-3T and SBP-1 were characterized using a polyphasic approach. Both IP3-3T and SBP-1 are mesophilic, non-spore-forming, non-motile and Gram-stain-negative. Cells of both strains are irregular cocci with diameters of 0.4–1.1 µm. Both are resistant to ampicillin and vancomycin. The genomic DNA G+C contents of strains IP3-3T and SBP-1 are 55.5±0.4 and 56.2±0.2 mol% (HPLC), respectively. Major cellular fatty acids include C18 : 1ω9c, C16 : 0, C14 : 0 and C16 : 1ω9c. 16S rRNA gene sequence based phylogenetic analyses indicated that the strains cluster within the phylum Chloroflexi most closely related to but distinct from the species Dehalogenimonas lykanthroporepellens (96.2 % pairwise similarity) and Dehalococcoides mccartyi (90.6 % pairwise similarity). Physiological and chemotaxonomic traits as well as phylogenetic analysis support the conclusion that these strains represent a novel species within the genus Dehalogenimonas for which the name Dehalogenimonas alkenigignens sp. nov. is proposed. The type strain is IP3-3T ( = JCM 17062T = NRRL B-59545T).

Native Cattle

Three strictly anaerobic, methanogenic strains JH1T, JH4 and JH8 were isolated from rumen of the Korean native cattle (HanWoo; Bos taurus coreanae) in South Korea. The colonies were circular, opaque, and slightly yellowish. Phylogenetic analyses of 16S rRNA gene and mcrA (encoding α subunit of methyl-coenzyme M reductase) sequences confirmed the affiliation of the novel strains with the Methanobacteriales , and Methanobrevibacter wolinii SHT was the most closely related species. The 16S rRNA gene and mcrA sequence similarities between strains JH1T, JH4 and JH8 and M. wolinii SHT were 96.2 and 89.0 % respectively, and DNA–DNA hybridization of the isolates and M. wolinii DSM 11976T showed a 20 % reassociation. Strain JH1T exhibited 92 % DNA–DNA relatedness with strains JH4 and JH8, and their 16S rRNA gene and mcrA sequences were identical. Cells stained Gram-positive and were non-motile rods, 1.5–1.8 µm long and 0.6 µm wide. The strains were able to use H2/CO2 and formate. The optimum temperature and pH ranges for growth were 37–40 °C and pH 6.5–7.0. The DNA G+C content of strain JH1T was 28 mol%. Based on data from this study using a polyphasic approach, the three strains represent a novel species of genus Methanobrevibacter , for which the name Methanobrevibacter boviskoreani sp. nov. is proposed. The type strain is JH1T ( = KCTC 4102T = JCM 18376T).

A Gram-stain-negative, rod-shaped and facultatively aerobic bacterial strain, designated F7430T, was isolated from coastal sediment collected at Jingzi Wharf in Weihai, PR China. Cells of strain F7430T were 0.3–0.4 µm wide, 2.0–2.6 µm long, non-flagellated, non-motile and formed pale-beige colonies. Growth was observed at 4–40 °C (optimum, 30 °C), pH 6.0–9.0 (optimum, pH 7.5–8.0) and at NaCl concentrations of 1.0–10.0 % (w/v; optimum, 1.0 %). The sole respiratory quinone of strain F7430T was ubiquinone 8 and the predominant cellular fatty acids were summed feature 8 (C18 : 1  ω7c / C18 : 1  ω6c; 60.7 %), summed feature 3 (C16 : 1  ω7c/C16 : 1  ω6c; 30.2 %) and C15 : 0 iso (13.9 %). The polar lipids of strain F7430T consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, one unidentified phospholipid and three unidentified lipids. Results of 16S rRNA gene sequences analyses indicated that this strain belonged to the family Halieaceae and had high sequence similarities to Parahaliea aestuarii JCM 51547T (95.3 %) and Halioglobus pacificus DSM 27932T (95.2 %) followed by 92.9–95.0 % sequence similarities to other type species within the aforementioned family. The rpoB gene sequences analyses indicated that the novel strain had the highest sequence similarities to Parahaliea aestuarii JCM 51547T (82.2 %) and Parahaliea mediterranea DSM 21924T (82.2 %) followed by 75.2–80.5 % sequence similarities to other type species within this family. Phylogenetic analyses showed that strain F7430T constituted a monophyletic branch clearly separated from the other genera of family Halieaceae . Whole-genome sequencing of strain F7430T revealed a 3.3 Mbp genome size with a DNA G+C content of 52.6 mol%. The genome encoded diverse metabolic pathways including the Entner–Doudoroff pathway, assimilatory sulphate reduction and biosynthesis of dTDP-l-rhamnose. Based on results from the current polyphasic study, strain F7430T is proposed to represent a novel species of a new genus within the family Halieaceae , for which the name Sediminihaliea albiluteola gen. nov., sp. nov. is proposed. The type strain of the type species is F7430T (=KCTC 72873T=MCCC 1H00420T).
