The 16S Rrna Gene

Analysis of the 16S rRNA gene sequences of species currently assigned to the genus Bacillus has shown an extensive intrageneric phylogenetic heterogeneity. The 16S rRNA gene sequence of Bacillus schlegelii ATCC 43741T shows only 82.2–85.9 % sequence similarity to type strains of other members of the genus Bacillus and <88.5 % sequence similarity to recognised species of the most closely related genera, Calditerricola (88.4–88.5 %), Planifilum (87.3–87.8 %) and Caldalkalibacillus (87.2−87.9 %). Furthermore, B. schlegelii ATCC 43741T could not be assigned to an existing family by phylogenetic analysis. The predominant menaquinone was MK-7. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, one unidentified phospholipid and two unidentified glycolipids. The major fatty acids were iso-C16 : 0, C16 : 0, iso-C17 : 0 and anteiso-C17 : 0. Both the polar lipid profile and the fatty acid composition clearly distinguished B. schlegelii DSM 2000T from the type species of the genus Bacillus , Bacillus subtilis . Hence, there is no evidence for a clear phenotypic grouping of this organism into the genus Bacillus nor to the genera Calditerricola , Caldalkalibacillus or Planifilum . A proposal is made to transfer Bacillus schlegelii to a novel genus and species, Hydrogenibacillus schlegelii gen. nov., comb. nov., and to emend the species description. The type strain of the type species is DSM 2000T ( = ATCC 43741T = CCUG 26017T = CIP 106933T).

The 16S Rrna Gene

Deinococcus species are widely studied due to their utility in bioremediation of sites contaminated with radioactive elements. In the present study, we re-evaluated the taxonomic placement of two species of the genus Deinococcus namely D. swuensis DY59T and D. radiopugnans ATCC 19172T based on whole genome analyses. The 16S rRNA gene analysis revealed a 99.58% sequence similarity between this species pair that is above the recommended threshold value for species delineation. These two species also clustered together in both the 16S rRNA gene and core genome based phylogenies depicting their close relatedness. Furthermore, more than 98% of genes were shared between D. swuensi s DY59T and D. radiopugnans ATCC 19172T. Interestingly, D. swuensis DY59T and D. radiopugnans ATCC 19172T shared high genome similarity in different genomic indices. They displayed an average nucleotide identity value of 97.63%, an average amino acid identity value of 97% and a digital DNA–DNA hybridization value equal to 79.50%, all of which are well above the cut-off for species delineation. Altogether, based on these evidences, D. swuensis DY59T and D. radiopugnans ATCC 19172T constitute a single species. Hence, as per the priority of publication, we propose that Deinococcus swuensis Lee et al. 2015 should be reclassified as a later heterotypic synonym of Deinococcus radiopugnans .

The 16S Rrna Gene

Two novel thermophilic bacteria, designated SgZ-9T and SgZ-10T, were isolated from compost. Cells of the two strains were catalase-positive, endospore-forming and Gram-staining-positive rods. Strain SgZ-9T was oxidase-positive and non-motile, and strain SgZ-10T was oxidase-negative and motile. The highest 16S rRNA gene sequence similarity for both strains SgZ-9T and SgZ-10T was observed with Bacillus fortis (97.5 % and 96.9 %, respectively). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SgZ-9T formed a cluster with B. fortis R-6514T and Bacillus fordii R-7190T, and SgZ-10T formed a cluster with Bacillus farraginis R-6540T. The DNA–DNA pairing studies showed that SgZ-9T displayed 41.6 % and 30.7 % relatedness to the type strains of B. fortis and B. fordii , respectively. The 16S rRNA gene sequence similarity between strains SgZ-9T and SgZ-10T was 97.2 %, and the level of DNA–DNA relatedness between them was 39.2 %. The DNA G+C content of SgZ-9T and SgZ-10T was 45.3 and 47.9 mol%, respectively. Chemotaxonomic analysis revealed that both strains contained the menaquinone 7 (MK-7) as the predominant respiratory quinone. The major cellular fatty acids (>5 %) were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C17 : 0 in SgZ-9T and iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0, anteiso-C17 : 0 and iso-C16 : 0 in SgZ-10T. Based on the phenotypic characteristics, chemotaxonomic features, DNA–DNA hybridization with the nearest phylogenetic neighbours and phylogenetic analysis based on the 16S rRNA gene sequences, the two strains were determined to be two distinct novel species in the genus Bacillus , and the names proposed are Bacillus composti sp. nov. SgZ-9T ( = CCTCC AB2012109T = KACC 16872T) and Bacillus thermophilus sp. nov. SgZ-10T (CCTCC AB2012110T = KACC 16873T).

Two strains of lactic acid bacteria, designated Hs20B0-1T and Hs30E4-3T, were isolated from the gut of the damp-wood termite Hodotermopsis sjostedti. These strains were characterized genetically and phenotypically. Strain Hs20B0-1T was related to Lactococcus piscium DSM 6634T showing 96.3 and 84.2 % sequence similarity in 16S rRNA gene and rpoB gene sequences, respectively. Strain Hs30E4-3T was related to Lactococcus plantarum DSM 20686T showing 94.8 and 82.2 % sequence similarity in 16S rRNA gene and rpoB gene sequences, respectively. The 16S rRNA gene sequence similarity between strains Hs20B0-1T and Hs30E4-3T was 95.7 %. Furthermore, genomic comparisons using pairwise average nucleotide identity (ANI) and digital DNA–DNA hybridization (DDH) analyses between strain Hs20B0-1T and L. piscium DSM 6634T resulted in values of 73.5 and 20.1 %, respectively. Strain Hs30E4-3T had 72.8 % ANI similarity and 21.3 % DDH similarity to L. plantarum DSM 20686T. Strains Hs20B0-1T and Hs30E4-3T had 75.4 % ANI similarity and 21.1 % DDH similarity to each other. The cell-wall peptidoglycan types of strains Hs20B0-1T and Hs30E4-3T were A4α, Lys-Asp and A3α, Lys–Thr–Ala, respectively. The two strains, Hs20B0-1T and Hs30E4-3T, are distinguishable from each other and other established Lactococcus species phylogenetically and phenotypically. In conclusion, two novel species of the genus Lactococcus are proposed, namely Lactococcus insecticola Hs20B0-1T (=JCM 33485T=DSM 110147T) and Lactococcus hodotermopsidis Hs30E4-3T (=JCM 33486T=DSM 110148T), respectively.

A novel bacterium, strain MUSC 273T, was isolated from mangrove sediments of the Tanjung Lumpur river in the state of Pahang in peninsular Malaysia. The bacterium was yellow-pigmented, Gram-negative, rod-shaped and non-spore-forming. The taxonomy of strain MUSC 273T was studied by a polyphasic approach and the organism showed a range of phenotypic and chemotaxonomic properties consistent with those of the genus Novosphingobium . The 16S rRNA gene sequence of strain MUSC 273T showed the highest sequence similarity to those of Novosphingobium indicum H25T (96.8 %), N. naphthalenivorans TUT562T (96.4 %) and N. soli CC-TPE-1T (95.9 %) and lower sequence similarity to members of all other species of the genus Novosphingobium . Furthermore, in phylogenetic analyses based on the 16S rRNA gene sequence, strain MUSC 273T formed a distinct cluster with members of the genus Novosphingobium . DNA–DNA relatedness of strain MUSC 273T to the type strains of the most closely related species, N. indicum MCCC 1A01080T and N. naphthalenivorans DSM 18518T, was 29.2 % (reciprocal 31.0 %) and 17 % (reciprocal 18 %), respectively. The major respiratory quinone was ubiquinone Q-10, the major polyamine was spermidine and the DNA G+C content was 63.3±0.1 mol%. The polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidyldimethylethanolamine, phosphatidylcholine and sphingoglycolipid. The major fatty acids were C18 : 1ω7c, C17 : 1ω6c, C16 : 0, C15 : 0 2-OH and C16 : 1ω7c. Comparison of BOX-PCR fingerprints indicated that strain MUSC 273T represented a unique DNA profile. The combined genotypic and phenotypic data showed that strain MUSC 273T represents a novel species of the genus Novosphingobium , for which the name Novosphingobium malaysiense sp. nov. is proposed. The type strain is MUSC 273T ( = DSM 27798T = MCCC 1A00645T = NBRC 109947T).

A bacterial strain, BIT-B35T, was isolated from the gut of plastic-eating larvae of the Coleoptera insect Zophobas atratus. Its taxonomic position was determined by using a polyphasic approach. Cells were white-pigmented, Gram-stain-negative, motile short rods with terminal flagella. The 16S rRNA gene sequence (1411 bp) of strain BIT-B35T showed highest similarity (98.1%) to Escherichia fergusonii ATCC 35469T and Citrobacter koseri LMG 5519T. The results of phylogenetic analyses, based on the 16S rRNA gene, concatenated sequences of seven housekeeping genes (atpD, gyrB, infB, rpoB, pyrG, fusA and leuS) and genome sequences, placed strain BIT-B35T in a separate lineage among the family of Enterobacteriaceae . The major fatty acids were C16 : 0, C17 : 0 cyclo and C19 : 0 cyclo ω8c. The genomic DNA G+C content of strain BIT-B35T was 57.1 mol%. The chemotaxonomic data plus results of physiological and biochemical tests also distinguished strain BIT-B35T from members of other genera within the family Enterobacteriaceae . Therefore, strain BIT-B35T is considered to represent a novel species of a novel genus within the family Enterobacteriaceae , for which the name Intestinirhabdus alba gen. nov., sp. nov. is proposed. The type strain is BIT-B35T (=CGMCC 1.17042T=KCTC 72448T).

Strain S658T was isolated from a Lotus corniculatus nodule in a soil sample obtained in Uruguay. Phylogenetic analysis of the 16S rRNA gene and atpD gene showed that this strain clustered within the genus Phyllobacterium . The closest related species was, in both cases, Phyllobacterium trifolii PETP02T with 99.8 % sequence similarity in the 16S rRNA gene and 96.1 % in the atpD gene. The 16S rRNA gene contains an insert at the beginning of the sequence that has no similarities with other inserts present in the same gene in described rhizobial species. Ubiquinone Q-10 was the only quinone detected. Strain S658T differed from its closest relatives through its growth in diverse culture conditions and in the assimilation of several carbon sources. It was not able to reproduce nodules in Lotus corniculatus. The results of DNA–DNA hybridization, phenotypic tests and fatty acid analyses confirmed that this strain should be classified as a representative of a novel species of the genus Phyllobacterium , for which the name Phyllobacterium loti sp. nov. is proposed. The type strain is S658T( = LMG 27289T = CECT 8230T).

Strains LMG 27428T and LMG 27427 were isolated from the caecal content of a chicken and produced butyric, lactic and formic acids as major metabolic end products. The genomic DNA G+C contents of strains LMG 27428T and LMG 27427 were 40.4 and 38.8 mol%. On the basis of 16S rRNA gene sequence similarity, both strains were most closely related to the generically misclassified Streptococcus pleomorphus ATCC 29734T. Strain LMG 27428T could be distinguished from S. pleomorphus ATCC 29734T based on production of more lactic acid and less formic acid in M2GSC medium, a higher DNA G+C content and the absence of activities of acid phosphatase and leucine, arginine, leucyl glycine, pyroglutamic acid, glycine and histidine arylamidases, while strain LMG 27428 was biochemically indistinguishable from S. pleomorphus ATCC 29734T. The novel genus Faecalicoccus gen. nov. within the family Erysipelotrichaceae is proposed to accommodate strains LMG 27428T and LMG 27427. Strain LMG 27428T ( = DSM 26963T) is the type strain of Faecalicoccus acidiformans sp. nov., and strain LMG 27427 ( = DSM 26962) is a strain of Faecalicoccus pleomorphus comb. nov. (type strain LMG 17756T = ATCC 29734T = DSM 20574T). Furthermore, the nearest phylogenetic neighbours of the genus Faecalicoccus are the generically misclassified Eubacterium cylindroides DSM 3983T (94.4 % 16S rRNA gene sequence similarity to strain LMG 27428T) and Eubacterium biforme DSM 3989T (92.7 % 16S rRNA gene sequence similarity to strain LMG 27428T). We present genotypic and phenotypic data that allow the differentiation of each of these taxa and propose to reclassify these generically misnamed species of the genus Eubacterium formally as Faecalitalea cylindroides gen. nov., comb. nov. and Holdemanella biformis gen. nov., comb. nov., respectively. The type strain of Faecalitalea cylindroides is DSM 3983T = ATCC 27803T = JCM 10261T and that of Holdemanella biformis is DSM 3989T = ATCC 27806T = CCUG 28091T.

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, strain SC13E-S71T, was isolated from tuff, volcanic rock, where the Roman catacombs of Saint Callixtus in Rome, Italy, was excavated. Analysis of 16S rRNA gene sequences revealed that strain SC13E-S71T belongs to the genus Sphingopyxis , and that it shows the greatest sequence similarity with Sphingopyxis chilensis DSM 14889T (98.72 %), Sphingopyxis taejonensis DSM 15583T (98.65 %), Sphingopyxis ginsengisoli LMG 23390T (98.16 %), Sphingopyxis panaciterrae KCTC 12580T (98.09 %), Sphingopyxis alaskensis DSM 13593T (98.09 %), Sphingopyxis witflariensis DSM 14551T (98.09 %), Sphingopyxis bauzanensis DSM 22271T (98.02 %), Sphingopyxis granuli KCTC 12209T (97.73 %), Sphingopyxis macrogoltabida KACC 10927T (97.49 %), Sphingopyxis ummariensis DSM 24316T (97.37 %) and Sphingopyxis panaciterrulae KCTC 22112T (97.09 %). The predominant fatty acids were C18 : 1ω7c, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), C14 : 0 2-OH and C16 : 0. The predominant menaquinone was MK-10. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. These chemotaxonomic data are common to members of the genus Sphingopyxis . However, a polyphasic approach using physiological tests, DNA base ratios, DNA–DNA hybridization and 16S rRNA gene sequence comparisons showed that the isolate SC13E-S71T belongs to a novel species within the genus Sphingopyxis , for which the name Sphingopyxis italica sp. nov. is proposed. The type strain is SC13E-S71T ( = DSM 25229T = CECT 8016T).

A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529T, was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22–50 °C (optimum 28–45 °C), the pH range for growth was 6.0–8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0–7 % (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 1ω6c, iso-C16 : 1 H and C16 : 1ω7c/iso-C15 : 0 2-OH. The DNA G+C content of strain SCSIO 11529T was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529T belongs to the genus Prauserella , with the closest neighbours being Prauserella marina MS498T (97.0 % 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194T (96.4 %) and Prauserella flava YIM 90630T (95.9 %). Based on the evidence of the present study, strain SCSIO 11529T is considered to represent a novel species of the genus Prauserella , for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529T ( = DSM 45821T = NBRC 109418T).
