RESUMEN
A Gram-staining-positive, motile, aerobic and rod-shaped bacterium, designated strain MA9T was isolated from wetland soil of ecology park, in Seoul, Republic of Korea. This bacterium was characterized to determine its taxonomic position by using the polyphasic approach. Strain MA9T grew at 10-37 °C and at pH 6.0-9.5 on TSB. Menaquinone MK-7 was the predominant respiratory quinone and iso-C15â:â0, iso-C16â:â0 and C16â:â1 ω7c alcohol were the major fatty acids. The main polar lipids were phosphatidylethanolamine (PE), phosphatidylserine (PS), diphosphatidylglycerol (DPG) and phosphatidylglycerol (PG). The peptidoglycan type of the cell wall was A4α l-Lys-d-Glu. Based on 16S rRNA gene sequencing, strain MA9T clustered with species of the genus Solibacillus and appeared closely related to S. silvestris DSM 12223T (97.8â% sequence similarity), S. cecembensis DSM 21993T (97.6â%), S. isronensis DSM 21046T (97.6â%) and S. kalamii DSM 101595T (96.6â%). The G+C content of the genomic DNA was 37.0 mol%. Digital DNA-DNA hybridization between strain MA9T and type strains of S. silvestris, S. isronensis, S. cecembensis and S. kalamii resulted in values below 70â%. Strain MA9T could be differentiated genotypically and phenotypically from the recognized species of the genus Solibacillus. The isolate therefore represents a novel species, for which the name Solibacillus palustris sp. nov. is proposed, with the type strain MA9T (=KACC 22212T = LMG 32188T).

An obligately anaerobic, Gram-positive, non-motile, coccus-shaped bacterial strain designated AGMB00490T was isolated from swine faeces. 16S rRNA gene sequence-based phylogenetic analysis indicated that the isolate belongs to the genus Peptoniphilus and that the most closely related species is Peptoniphilus gorbachii WAL 10418T (=KCTC 5947T, 97.22â% 16S rRNA gene sequence similarity). Whole genome sequence analysis determined that the DNA G+C content of strain AGMB00490T was 31.2 mol% and moreover that the genome size and numbers of tRNA and rRNA genes were 2â129â517 bp, 34 and 10, respectively. Strain AGMB00490T was negative for oxidase and urease; positive for catalase, indole production, arginine arylamidase, leucine arylamidase, tyrosine arylamidase and histidine arylamidase; and weakly positive for phenylalanine arylamidase and glycine arylamidase. The major cellular fatty acids (>10â%) of the isolate were determined to be C16â:â0 and C18â:â1 ω9c. Strain AGMB00490T produced acetic acid as a major end product of metabolism. Accordingly, phylogenetic, physiologic and chemotaxonomic analyses revealed that strain AGMB00490T represents a novel species for which the name Peptoniphilus faecalis sp. nov. is proposed. The type strain is AGMB00490T (=KCTC 15944T=NBRC 114159T).

The novel strain AM35T was isolated from the faeces of C57BL/6 mice. These cells are strictly anaerobic, gram negative, oxidase negative, catalase positive, rod-shaped and non-motile. The strain produced creamy yellowish colonies on brain heart infusion (BHI) agar with hemin. Growth was investigated at 30-41 °C in the presence of 0.5-1.5% (w/v) NaCl at pH 6.5-8.5. Taxonomic analysis based on 16S rRNA gene sequencing revealed that strain AM35T is affiliated with the family Muribaculaceae and closely related to the genus Muribaculum. The genomic DNA G + C content of strain AM35T was 47.8 mol%. We detected the whole-cell sugars ribose and galactose; meso-2,6-diaminopimelic acid was absent. The major fatty acids (> 10%) were anteiso-C15:0 and iso-C15:0; the major polar lipid was phosphatidylethanolamine. The major respiratory quinones were MK-10 and MK-11. Based on our phylogenetic, phenotypic and chemotaxonomic analyses, strain AM35T represents a novel genus within the family Muribaculaceae, for which we propose the name Heminiphilus faecis gen. nov., sp. nov. The type strain of Heminiphilus faecis gen. nov., sp. nov. is AM35T (= KCTC 15907 T = DSM 110151 T).

The vaginal microbiota may be important for pregnancy prognosis because vaginal dysbiosis during pregnancy appears to be related to preterm birth (PTB) or pregnancy loss. Previous reports have indicated that a Lactobacillus-poor microbial flora in the vagina and intrauterine infection by diverse anaerobes ascending from the vagina are associated with undesirable delivery outcomes. However, no research has involved the use of pyrosequencing analysis to examine vaginal microbiota profiles or their potential associations with high-risk pregnancy in Korean women. Vaginal swabs were collected from 500 Korean women for the identification of community state types (CSTs). Of these, 137 samples were further analyzed using a Roche/454 GS Junior pyrosequencer. Three distinct CSTs were identified based on the dominant vaginal microbes: CST I (Lactobacillus crispatus dominated), CST III (Lactobacillus iners dominated), and CST IV (with diverse species of anaerobes). Twelve of the 67 pregnant women had undesirable pregnancy outcomes (four miscarriages and eight PTBs). The dominant microbe in the vaginal microbiota of women who gave birth at full-term was L. crispatus. In contrast, L. iners was the dominant vaginal microbe in women who miscarried. Most (n = 6/8) vaginal microbiota profiles of women who experienced PTB could be classified as CST IV, with diverse bacteria, including anaerobic vaginal species. The present study provides valuable information regarding the characteristics of the vaginal microbiota of Korean women related to high-risk pregnancy. Investigation of the vaginal microbiotic structure in pregnant Korean women is necessary to enable better prediction of adverse pregnancy outcomes.

A novel Gram-reaction-negative, facultative-aerobic, motile, non-spore-forming, oval-shaped and denitrifying bacterium, designated BO-81T, was isolated from sludge sampled in the Republic of Korea. This bacterium was investigated via a polyphasic approach to reveal its taxonomic position. The results of phylogenetic analysis based on 16S rRNA gene sequencing indicated that strain BO-81T belonged to the family Rhodobacteraceae and was related to the closest species Sinirhodobacter ferrireducens (98.8â% sequence similarity), 'Sinorhodobacter hungdaonensis' (98.4 %), Rhodobacter lacus (97.8â%), Sinorhodobacter populi (96.8â%) and Rhodobacter maris (96.2â%). The average nucleotide identity and DNA-DNA hybridization values between strain BO-81T and its closely related strains were 77.7-94.2â% and 20.1-55.9â%, respectively, indicating that BO-81T represents a novel species of the genus Sinirhodobacter. Growth occurred at 18-40 °C on Reasoner's 2A medium in the presence of 0-7â% NaCl (w/v) and at pH 6.0-9.0. Strain BO-81T was characterized chemotaxonomically as having ubiquinone 10 as its predominant respiratory quinone, summed feature 8 (C18â:â1 ω6c and/or C18â:â1 ω7c) as its major fatty acid and phosphatidylglycerol and phosphatidylethanolamine as its predominant polar lipids. The G+C content of the genomic DNA was 68.3 mol%. The results of physiological and biochemical tests allowed phenotypic differentiation of strain BO-81T from other Sinirhodobacter species with validly published names. Therefore, the isolate represented a novel species, for which the name Sinirhodobacter hankyongi sp. nov. (type strain BO-81T=KACC 19677T=LMG 30808T) is proposed.

Akkermansia muciniphila is widely considered a next-generation beneficial microbe. This bacterium resides in the mucus layer of its host and regulates intestinal homeostasis and intestinal barrier integrity by affecting host signaling pathways. However, it remains unknown how the expression of genes encoding extracellular proteins is regulated in response to dynamic mucosal environments. In this study, we elucidated the effect of mucin on the gene expression and probiotic traits of A. muciniphila. Transcriptome analysis showed that the genes encoding most mucin-degrading enzymes were significantly upregulated in the presence of mucin. By contrast, most genes involved in glycolysis and energy metabolic pathways were upregulated under mucin-depleted conditions. Interestingly, the absence of mucin resulted in the upregulation of 79 genes encoding secreted protein candidates, including Amuc-1100 as well as members of major protein secretion systems. These transcript level changes were consistent with the fact that administration of A. muciniphila grown under mucin-depleted conditions to high-fat diet-induced diabetic mice reduced obesity and improved intestinal barrier integrity more efficiently than administration of A. muciniphila grown under mucin-containing conditions. In conclusion, mucin content in the growth medium plays a critical role in the improvement by A. muciniphila of high-fat diet-induced obesity, intestinal inflammation, and compromised intestinal barrier integrity related to a decrease in goblet cell density. Our findings suggest the depletion of animal-derived mucin in growth medium as a novel principle for the development of A. muciniphila for human therapeutics.

RESUMEN
A facultatively anaerobic, Gram-stain-positive, catalase-negative, rod-shaped lactic acid bacterium, designated SG816T, was isolated from small intestine of a swine. Optimal growth occurred at 37 °C and pH 7.0. Furthermore, growth occurred in NaCl up to 0.5â% (w/v) but not at levels of salinity higher than 1â%. Comparative 16S rRNA gene sequencing and the matrix-associated laser desorption/ionization-time-of-flight mass spectometry profiling showed that strain SG816T was closely related to Lactobacillus delbrueckiisubsp. bulgaricus KCTC 3635T (95.9â%) and Lactobacillus delbrueckiisubsp. indicus JCM 15610T (95.9â%), followed by other Lactobacillus delbrueckii subspecies (95.9-95.7â%) and Lactobacillus equicursoris DSM 19284T (95.6â%). A comparison of two housekeeping genes, RNA polymerase alpha subunit (rpoA) and phenylalanyl-tRNA synthase alpha subunit (pheS), revealed that strain SG816T formed a separate branch within the clade of the genus Lactobacillus. The DNA G+C content level of the strain SG816T was 51.5 mol%. The strain was homofermentative and produced d-lactic acid from glucose fermentation. The major cellular fatty acids (>10â%) of the isolate were C18â:â1ω9c and C16â:â0. The peptidoglycan type was A4α l-Lys-d-Asp. On the basis of distinct phenotypic and phylogenetic properties, strain SG816T represents a novel species of the genus Lactobacillus, for which the name Lactobacillus porci sp. nov. is proposed. The type strain is SG816T (=KCTC 21090T=NBRC 112917T).

Three bacterial isolates from human faeces, YS-aM39T, R2F3-3-3T and R2F3-5-1, were characterized as Gram-negative, strictly anaerobic, non-spore-forming, non-motile, and rod-shaped. Isolate YS-aM39T formed a distinct line of descent, showing greatest 16S rRNA gene sequence relatedness with R2F3-3-3T (97.5â%), R2F3-5-1 (97.5â%), Bacteroides ovatus (98.8â%) and Bacteroides xylanisolvens (97.2â%). Isolates R2F3-3-3T and R2F3-5-1 also formed a distinct line of descent, sharing greatest 16S rRNA gene sequence relatedness with B. ovatus (98.2â%) and B. xylanisolvens (97.2â%). The DNA G+C content of YS-aM39T was 44.8 mol%, that of R2F3-3-3T was 42.4 mol% and that of R2F3-5-1 was 42.6 mol%. The respiratory quinone of all three isolates was menaquinone MK-10. Polar lipid analysis identified phosphatidylethanolamine as the major lipid. The predominant fatty acids in all three isolates were anteiso-C15â:â0, iso-C15â:â0, C16â:â0 3-OH and iso-C17â:â0 3-OH. The major end products of glucose fermentation were acetic acid, lactic acid and formic acid. DNA-DNA hybridization data indicated that two isolates, YS-aM39T and R2F3-3-3T, represent a species distinct from B. ovatus and B. xylanisolvens. Finally, in this study, the two isolates represented two new species in the genus Bacteroides, for which we propose the names Bacteroides koreensis sp. nov. (type strain, YS-aM39T=KCTC 15520T=JCM 31393T) and Bacteroides kribbi sp. nov. (type strain, R2F3-3-3T=KCTC 15460T=JCM 31391T).

Two bacterial strains, 46-1 and 46-2T, were isolated from garden soil. These strains were observed to be aerobic, Gram-stain negative, rod-shaped, non-spore-forming, motile and catalase and oxidase positive. Phylogenetic analysis based on 16S rRNA gene sequences showed that the two strains shared 100 % sequence similarity with each other and belong to the genus Pseudomonas in the class Gammaproteobacteria. The concatenated 16S rRNA, gyrB, rpoB and rpoD gene sequences further confirmed that the isolates belong to the Pseudomonas koreensis subgroup (SG), with P. koreensis Ps 9-14T, Pseudomonas moraviensis 1B4T and Pseudomonas granadensis F-278,770T as their close relatives (>96 % pairwise similarity). DNA-DNA hybridization with the closely related type strain P. koreensis SG revealed a low level of relatedness (<50 %). A cladogram constructed using whole-cell matrix-assisted laser desorption/ionization time-of-flight (WC-MALDI-TOF) MS analysis showed the isolates formed a completely separate monophyletic group. The isolates were negative for utilization of glycogen, D-psicose, α-keto butyric acid, α-keto valeric acid, succinamic acid and D, L-α-glycerol phosphate. In contrast, all these reactions were positive in P. koreensis JCM 14769T and P. moraviensis DSM 16007T. The fatty acid C17:0 cyclo was detected as one of the major cellular fatty acids (>15 %) in the isolates but it was a minor component (<4 %) in both reference type strains. In contrast, the fatty acid, C12:0 was not observed in the isolates but was present in both reference strains. Based on differences such as phylogenetic position, low-level DNA-DNA hybridization, WC-MALDI-TOF MS analysis, fluorescence pigmentation, fatty acid profiles, and substrate utilization, we propose that the isolates 46-1 and 46-2T represent a novel species of the genus Pseudomonas, for which the name Pseudomonas kribbensis sp. nov. is proposed; the type strain is 46-2T (=KCTC 32541T = DSM 100278T).

A novel bacterial strain, SR79T, was isolated from a Korean faecal sample and characterized using a polyphasic approach. SR79T was found to be a strictly anaerobic, Gram-stain-positive, non-spore-forming, non-motile, catalase- and oxidase-negative short rod with no flagella. SR79T grew optimally at 37 °C in the presence of 0.5 % (w/v) NaCl at pH 7. The NaCl range for growth was 0-1 % (w/v). The isolate produced butyric acid (>18 mM) as a major end product. A phylogenetic analysis based on 16S rRNA gene sequences revealed that the most closely related type strains were Eubacteriumdesmolans ATCC 43058T and Butyricicoccus pullicaecorum 25-3T (96.4 and 96.0 % similarity, respectively). The DNA G+C content was determined to be 52.9 mol%. The major cellular fatty acids (>10 %) were C16 : 0, C18 : 1cis-9, C19 : 1 cyc 9,10 and C14 : 0. Meso-diaminopimelic acid was present in the cell wall peptidoglycan and the cell wall hydrolysates contained ribose, glucose and galactose. The 16S rRNA gene sequence similarity, phylogenetic analysis, chemotaxonomic and phenotypic characteristics allowed differentiation of SR79T, which represents a novel species of a new genus within the family Ruminococcaceae, for which the name Agathobaculum butyriciproducens gen. nov. sp. nov. is proposed. The type strain is SR79T (=KCTC 15532T=DSM 100391T). Based on the results of this study, it is also proposed to transfer Eubacteriumdesmolans to this new genus, as Agathobaculum desmolans comb. nov. The type strain of Agathobaculum desmolans is ATCC 43058T (=CCUG 27818T).

A novel actinobacterial strain, AD1-86T, was isolated from the vaginal fluid of a Korean female and was characterized by a polyphasic approach. The strain was a facultatively anaerobic, Gram-stain-positive, non-spore-forming, non-motile, catalase-positive and oxidase-negative short rod. Colonies were creamy white, of low convexity and 1-2âmm in diameter after growth on DSM 92 agar plates at 37 °C for 2âdays. The most closely related strains were Dermabacter hominis DSM 7083T and Helcobacillus massiliensis 6401990T (98.3 and 96.3 % 16S rRNA gene sequence similarity, respectively). The isolate grew optimally at 37 °C and pH 7 in the presence of 0.5% (w/v) NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid and the cell-wall hydrolysates contained ribose, galactose and glucose. The DNA G+C content was 62.6âmol% and the mean DNA-DNA relatedness value of the isolate to D. hominis DSM 7083T was 31.1±3.0% (reciprocal: 48.2±5.3%). The major cellular fatty acids (>10%) were anteiso-C17:0, anteiso-C15:0 and iso-C16:0, and the menaquinones were MK-9, MK-8 and MK-7. The polar lipid profile of strain AD1-86T consisted of diphosphatidylglycerol, phosphatidylglycerol, two aminolipids and a glycolipid. Data from this polyphasic study indicate that strain AD1-86T represents a novel species of the genus Dermabacter, for which the name Dermabacter vaginalis sp. nov. is proposed; the type strain is AD1-86T (=KCTC 39585T=DSM 100050T).

A novel strictly anaerobic strain, ALO17(T), was isolated from mouse faeces and found to produce lactic acid as a major metabolic end product. The isolate was observed to be Gram-stain positive, non-motile, non-spore forming small rods, oxidase and catalase negative, and to form cream-coloured colonies on DSM 104 agar plates. The NaCl range for growth was determined to be 0-2 % (w/v). The isolate was found to grow optimally at 37 °C, with 0.5 % (w/v) NaCl and at pH 7. The cell wall hydrolysates were found to contain ribose as a major sugar. The genomic DNA G+C content was determined to be 52.3 mol%. A phylogenetic analysis of the 16S rRNA gene sequence revealed that Holdemanella biformis DSM 3989(T), Faecalicoccus pleomorphus ATCC 29734(T), Faecalitalea cylindroides ATCC 27803(T), and Allobaculum stercoricanis DSM 13633(T) are closely related to the isolate (87.4, 87.3, 86.9 and 86.9 % sequence similarity), respectively. The major cellular fatty acids (>10 %) of the isolate were identified as C18:1 cis 9 FAME (36.9 %), C16:0 FAME (33.7 %) and C18:0 FAME (13.2 %). In contrast to the tested reference strains, C20:0 FAME (4.0 %) was detected only in strain ALO17(T) whilst C16:0 DMA was absent. The isolate also differed in its substrate oxidation profiles from the reference strains by being positive for D-melibiose and stachyose but negative for N-acetyl-D-galactosamine and 3-methyl-D-glucose. On the basis of polyphasic taxonomic evidence from this study, the isolate is concluded to belong to a novel genus within the family Erysipelothricaceae. We propose the name Faecalibaculum rodentium gen. nov., sp. nov. to accommodate strain ALO17(T) (=KCTC 15484(T) = JCM 30274(T)) as the type strain.
