A Report of Nine Unrecorded Bacterial Species in the Phylum Bacteroidetes Collected from Freshwater Environments in Korea
Journal of Species Research 7(3):187-192, 2018 A report of nine unrecorded bacterial species in the phylum Bacteroidetes collected from freshwater environments in Korea Sanghwa Park, Kiwoon Beak, Ji-Hye Han, Yoon-Jong Nam and Mi-Hwa Lee* Bacterial Resources Research Division, Freshwater Bioresources Research Bureau, Nakdonggang National Institute of Biological Resources (NNIBR), Sangju, Gyengsangbuk-do 37242, Republic of Korea *Correspondent: [email protected] During a comprehensive study of indigenous prokaryotic species in South Korea, nine bacterial species in the phylum Bacteroidetes were isolated from freshwater environmental samples that were collected from three major rivers in the Republic of Korea. High 16S rRNA gene sequence similarity (≥98.7%) and robust phylogenetic clades with the closely related species suggest that each strain was correctly assigned to an independent and predefined bacterial species. There were no previous reports of these nine species in Korea. Within the phylum Bacteroidetes, four species were assigned to the genus Flavobacterium, order Flavobac- teriales, and five species to three genera of two families in the order Cytophagales. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section. Keywords: 16S rRNA gene, Bacteroidetes, Flavobacteriales, Cytophagales, unrecorded species Ⓒ 2018 National Institute of Biological Resources DOI:10.12651/JSR.2018.7.3.187 INTRODUCTION MATERIALS AND METHODS The phylum Bacteroidetes (Ludwig and Klenk, 2001), Samples of freshwater, brackish water, and sediment also known as the Bacteroides-Cytophaga-Flexibacter were collected from the Han River, Nakdong River, and group, are widely distributed over a diverse range of eco- Seomjin River. -

Life in the cold biosphere: The ecology of psychrophile communities, genomes, and genes Jeff Shovlowsky Bowman A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2014 Reading Committee: Jody W. Deming, Chair John A. Baross Virginia E. Armbrust Program Authorized to Offer Degree: School of Oceanography i © Copyright 2014 Jeff Shovlowsky Bowman ii Statement of Work This thesis includes previously published and submitted work (Chapters 2−4, Appendix 1). The concept for Chapter 3 and Appendix 1 came from a proposal by JWD to NSF PLR (0908724). The remaining chapters and appendices were conceived and designed by JSB. JSB performed the analysis and writing for all chapters with guidance and editing from JWD and co- authors as listed in the citation for each chapter (see individual chapters). iii Acknowledgements First and foremost I would like to thank Jody Deming for her patience and guidance through the many ups and downs of this dissertation, and all the opportunities for fieldwork and collaboration. The members of my committee, Drs. John Baross, Ginger Armbrust, Bob Morris, Seelye Martin, Julian Sachs, and Dale Winebrenner provided valuable additional guidance. The fieldwork described in Chapters 2, 3, and 4, and Appendices 1 and 2 would not have been possible without the help of dedicated guides and support staff. In particular I would like to thank Nok Asker and Lewis Brower for giving me a sample of their vast knowledge of sea ice and the polar environment, and the crew of the icebreaker Oden for a safe and fascinating voyage to the North Pole. -

Unveiling new molecular Opisthokonta diversity: A perspective from evolutionary genomics David López Escardó TESI DOCTORAL UPF / ANY 2017 DIRECTOR DE LA TESI Dr. Iñaki Ruiz Trillo DEPARTAMENT DE CIÈNCIES EXPERIMENTALS I DE LA SALUT ii Acknowledgements: Aquesta tesi va començar el dia que, mirant grups on poguer fer el projecte de màster, vaig trobar la web d'un grup de recerca que treballaven amb uns microorganismes, desconeguts per mi en aquell moment, per entendre l'origen dels animals. Tres o quatre assignatures de micro a la carrera, i cap d'elles tractava a fons amb protistes i menys els parents unicel·lulars dels animals. En fi, "Bitxos" raros, origen dels animals... em va semblar interessant. Així que em vaig presentar al despatx del Iñaki vestit amb el tratge de comercial de Tecnocasa, per veure si podia fer les pràctiques del Màster amb ells. El primer que vaig volguer remarcar durant l'entrevista és que no pretenia anar amb tratge a la feina, que no es pensés que jo de normal vaig tan seriós... Sigui com sigui, després de rumiar-s'ho, em va dir que endavant i em va emplaçar a fer una posterior entrevista amb els diferents membres del lab perquè tries un projecte de màster. Per tant, aquí el meu primer agraïment i molt gran, al Iñaki, per permetre'm, no només fer el màster, sinó també permetre'm fer aquesta tesis al seu laboratori. També per la llibertat alhora de triar projectes i per donar-li al MCG un ambient cordial on hi dóna gust treballar. Gràcies, doncs, per deixar-me entrar al món científic per la porta de la protistologia, la genòmica i l'evolució, que de ben segur m'acompanyaran sempre. -

Strikingly, these tiny protists can alternate between unicellular and multicellular states, making choanoflagellates powerful models to investigate the origin of animal multicellularity, the mechanisms underlying cell differentiation and the ancestry of synaptic protein machinery. We used electron microscopy to reconstruct in three dimensions the total subcellular composition of unicellular and multicellular choanoflagellates as well as the collar cells from a marine sponge. We found differences between single and multicellular choanoflagellates in structures associated with cellular energetics, membrane trafficking and cell morphology and identified a putative novel cell type within rosette colonies. These findings are an important step forward in reconstructing the biology of last common ancestor of the animals and suggests that both, temporal and spatial cell type differentiation was present in the stem lineage leading to animals. In the second part of my talk, I will present our recent discoveries on synaptic protein homologs found in choanoflagellates. -

Abstract: Deep-sea sediments are considered an extreme environment due to high atmospheric pressure and low temperatures, harboring novel microorganisms. To explore marine bacterial diversity in the southern Colombian Caribbean Sea, this study used 16S ribosomal RNA (rRNA) gene sequencing to estimate bacterial composition and diversity of six samples collected at different depths (1681 to 2409 m) in two localities (CCS_A and CCS_B). We found 1842 operational taxonomic units (OTUs) assigned to bacteria. -

Introduction Loss of marine biodiversity seems inevitable in the 21st century. In benthic marine systems, survivors will have to acclimatize to seawater constantly increasing in temperature and evolving chemically, while also needing to out-compete new opportunistic neighbors and possibly facing increased predation pressure. Last but not the least, with a metabolism already pushed to its limits, survivors will have to fight against emerging diseases. Recent studies have shown that thermal stresses on coral reef scleractinians (Vega Thurber et al., 2009), sponges (Webster et al., 2008) and coralline algae (Webster et al., 2010a) induce changes from a balanced, functional associated microflora to a pathogen-dominated one, causing disease before the physiological tolerance limits of the hosts are reached. -

Accordingly, taxonomic classification of the phylum, based on a limited number of features, proved difficult and controversial in the past, for example, when decisions were based on unresolved phylogenetic trees of the 16S rRNA gene sequence. Here we use a large collection of type-strain genomes from Bacteroidetes and closely related phyla for Edited by: assessing their taxonomy based on the principles of phylogenetic classification and Martin G.

It comprises two major clades: 1) the Metazoa and their unicellular relatives and 2) the Fungi and their unicellular relatives. There is, however, little knowledge of the role of opisthokont microbes in many natural environments, especially among non-metazoan and non-fungal opisthokonts. Here we begin to address this gap by analyzing high throughput 18S rDNA and 18S rRNA sequencing data from different European coastal sites, sampled at different size fractions and depths. In particular, we analyze the diversity and abundance of choanoflagellates, filastereans, ichthyosporeans, nucleariids, corallochytreans and their related lineages. -
