  • Eelgrass Sediment Microbiome As a Nitrous Oxide Sink in Brackish Lake Akkeshi, Japan

Vol. 34, No. 1, 13-22, 2019 https://www.jstage.jst.go.jp/browse/jsme2 doi:10.1264/jsme2.ME18103 Eelgrass Sediment Microbiome as a Nitrous Oxide Sink in Brackish Lake Akkeshi, Japan TATSUNORI NAKAGAWA1*, YUKI TSUCHIYA1, SHINGO UEDA1, MANABU FUKUI2, and REIJI TAKAHASHI1 1College of Bioresource Sciences, Nihon University, 1866 Kameino, Fujisawa, 252–0880, Japan; and 2Institute of Low Temperature Science, Hokkaido University, Kita-19, Nishi-8, Kita-ku, Sapporo, 060–0819, Japan (Received July 16, 2018—Accepted October 22, 2018—Published online December 1, 2018) Nitrous oxide (N2O) is a powerful greenhouse gas; however, limited information is currently available on the microbiomes involved in its sink and source in seagrass meadow sediments. Using laboratory incubations, a quantitative PCR (qPCR) analysis of N2O reductase (nosZ) and ammonia monooxygenase subunit A (amoA) genes, and a metagenome analysis based on the nosZ gene, we investigated the abundance of N2O-reducing microorganisms and ammonia-oxidizing prokaryotes as well as the community compositions of N2O-reducing microorganisms in in situ and cultivated sediments in the non-eelgrass and eelgrass zones of Lake Akkeshi, Japan. Laboratory incubations showed that N2O was reduced by eelgrass sediments and emitted by non-eelgrass sediments. qPCR analyses revealed that the abundance of nosZ gene clade II in both sediments before and after the incubation as higher in the eelgrass zone than in the non-eelgrass zone. In contrast, the abundance of ammonia-oxidizing archaeal amoA genes increased after incubations in the non-eelgrass zone only. Metagenome analyses of nosZ genes revealed that the lineages Dechloromonas-Magnetospirillum-Thiocapsa and Bacteroidetes (Flavobacteriia) within nosZ gene clade II were the main populations in the N2O-reducing microbiome in the in situ sediments of eelgrass zones.

  • Cryptic Inoviruses Revealed As Pervasive in Bacteria and Archaea Across Earth’S Biomes
    ARTICLES https://doi.org/10.1038/s41564-019-0510-x Corrected: Author Correction Cryptic inoviruses revealed as pervasive in bacteria and archaea across Earth’s biomes Simon Roux 1*, Mart Krupovic 2, Rebecca A. Daly3, Adair L. Borges4, Stephen Nayfach1, Frederik Schulz 1, Allison Sharrar5, Paula B. Matheus Carnevali 5, Jan-Fang Cheng1, Natalia N. Ivanova 1, Joseph Bondy-Denomy4,6, Kelly C. Wrighton3, Tanja Woyke 1, Axel Visel 1, Nikos C. Kyrpides1 and Emiley A. Eloe-Fadrosh 1* Bacteriophages from the Inoviridae family (inoviruses) are characterized by their unique morphology, genome content and infection cycle. One of the most striking features of inoviruses is their ability to establish a chronic infection whereby the viral genome resides within the cell in either an exclusively episomal state or integrated into the host chromosome and virions are continuously released without killing the host. To date, a relatively small number of inovirus isolates have been extensively studied, either for biotechnological applications, such as phage display, or because of their effect on the toxicity of known bacterial pathogens including Vibrio cholerae and Neisseria meningitidis. Here, we show that the current 56 members of the Inoviridae family represent a minute fraction of a highly diverse group of inoviruses. Using a machine learning approach lever- aging a combination of marker gene and genome features, we identified 10,295 inovirus-like sequences from microbial genomes and metagenomes. Collectively, our results call for reclassification of the current Inoviridae family into a viral order including six distinct proposed families associated with nearly all bacterial phyla across virtually every ecosystem.

Kyrpides3 and Malka Halpern1,5* Abstract Chryseobacterium bovis DSM 19482T (Hantsis-Zacharov et al., Int J Syst Evol Microbiol 58:1024-1028, 2008) is a Gram-negative, rod shaped, non-motile, facultative anaerobe, chemoorganotroph bacterium. C. bovis is a member of the Flavobacteriaceae, a family within the phylum Bacteroidetes. It was isolated when psychrotolerant bacterial communities in raw milk and their proteolytic and lipolytic traits were studied. Here we describe the features of this organism, together with the draft genome sequence and annotation. The DNA G + C content is 38.19%. The chromosome length is 3,346,045 bp. It encodes 3236 proteins and 105 RNA genes. The C. bovis genome is part of the Genomic Encyclopedia of Type Strains, Phase I: the one thousand microbial genomes study.

  • Nomenclature of Bacteria with Special Reference to the Order Actinomycetales'
    INTERNATIONAL JOURNAL OF SYSTEMATIC BACTERIOLOGY VOL. 21, No. 2 April 1971, pp. 197-206 Printed in U.S.A. Copyright 0 1971 International Association of Microbiological Societies Nomenclature of Bacteria with Special Reference to the Order Actinomycetales' THOMAS G. PRIDHAM Northern Regional Research Laboratory,z Peoria, Illinois 61604 The number of names for streptomycetes that is in the scientific literature now is exceeded only by those for organisms placed in the genus Bacillus Cohn 1872. The genus Streptomyces Waksman and Henrici 1943 may well rank in first place if names in the patent and quasiscientific literature are included. The overwhelming number of names and the lack of a precise definition of a particular species or subspecies, of type or neotype strains, and of certain essential details have brought about problems in assessing the status of many names. The major problems encountered in a 2-year study are discussed, and a simple format is suggested, use of which may help to clarify future nomenclature.

  • Glycomyces, a New Genus of the Actinomycetales D

Members of this genus are aerobic, produce nonfragmenting vegetative hyphae, and form chains of conidia on aerial sporophores. The cell walls are type I1 (rneso-diaminopimelic acid and glycine are present), and the whole-cell sugar patterns are type D (xylose and arabinose are present). The phospholipid pattern of both species is type P-I (no nitrogenous phospholipids). The guanine-plus-cytosine content of the deoxyribonucleic acid ranges from 71 to 73 mol%. The type strain of type species G. harbinensis is strain NRRL 15337 (= LL-D05139), and the type strain of G. rutgersensis is strain NRRL B-16106 (= LL-1-20). During the course of isolation of actinomycete strains Gordon et al. (8). Esculin hydrolysis was evaluated by the from soil for an antibiotic screening program, a novel isolate method of Williams et al.

  • Supplemental Material S1.Pdf
    Phylogeny of Selenophosphate synthetases (SPS) Supplementary Material S1 ! SelD in prokaryotes! ! ! SelD gene finding in sequenced prokaryotes! We downloaded a total of 8263 prokaryotic genomes from NCBI (see Supplementary Material S7). We scanned them with the program selenoprofiles (Mariotti 2010, http:// big.crg.cat/services/selenoprofiles) using two SPS-family profiles, one prokaryotic (seld) and one mixed eukaryotic-prokaryotic (SPS). Selenoprofiles removes overlapping predictions from different profiles, keeping only the prediction from the profile that seems closer to the candidate sequence. As expected, the great majority of output predictions in prokaryotic genomes were from the seld profile. We will refer to the prokaryotic SPS/SelD !genes as SelD, following the most common nomenclature in literature.! To be able to inspect results by hand, and also to focus on good-quality genomes, we considered a reduced set of species. We took the prok_reference_genomes.txt list from ftp://ftp.ncbi.nlm.nih.gov/genomes/GENOME_REPORTS/, which NCBI claims to be a "small curated subset of really good and scientifically important prokaryotic genomes". We named this the prokaryotic reference set (223 species - see Supplementary Material S8). We manually curated most of the analysis in this set, while we kept automatized the !analysis on the full set.! We detected SelD proteins in 58 genomes (26.0%) in the prokaryotic reference set (figure 1 in main paper), which become 2805 (33.9%) when considering the prokaryotic full set (figure SM1.1). The difference in proportion between the two sets is due largely to the presence of genomes of very close strains in the full set, which we consider redundant.

Wastewater treatment plants (WWTPs) are thought to be “hotspots” for antibiotic resistance dissemination. The conditions of WWTPs, in conjunction with the persistence of commonly used antibiotics, may favor the selection and transfer of resistance genes among bacterial populations. WWTPs provide an important ecological niche to examine the spread of antibiotic resistance. We used heterotrophic plate count methods to identify Citation: Sorgen, A.; Johnson, J.; phenotypically resistant cultivable portions of these bacterial communities and characterized the Lambirth, K.; Clinton,
