A Study on the Phototrophic Microbial Mat Communities of Sulphur Mountain Thermal Springs and Their Association with the Endangered, Endemic Snail Physella Johnsoni
A Study on the Phototrophic Microbial Mat Communities of Sulphur Mountain Thermal Springs and their Association with the Endangered, Endemic Snail Physella johnsoni By Michael Bilyj A thesis submitted to the Faculty of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science Department of Microbiology Faculty of Science University of Manitoba Winnipeg, Manitoba October 2011 © Copyright 2011, Michael A. Bilyj 1 Abstract The seasonal population fluctuation of anoxygenic phototrophs and the diversity of cyanobacteria at the Sulphur Mountain thermal springs of Banff, Canada were investigated and compared to the drastic population changes of the endangered snail Physella johnsoni. A new species and two strains of Rhodomicrobium were taxonomically characterized in addition to new species of Rhodobacter and Erythromicrobium. Major mat-forming organisms included Thiothrix-like species, oxygenic phototrophs of genera Spirulina, Oscillatoria, and Phormidium and purple nonsulfur bacteria Rhodobacter, Rhodopseudomonas and Rhodomicrobium. Aerobic anoxygenic phototrophs comprised upwards of 9.6 x 104 CFU/cm2 of mat or 18.9% of total aerobic heterotrophic bacterial isolates at certain sites, while maximal purple nonsulfur and purple sulfur bacteria were quantified at 3.2 x 105 and 2.0 x 106 CFU/cm2 of mat, respectively. Photosynthetic activity measurements revealed incredibly productive carbon fixation rates averaging 40.5 mg C/cm2/24 h. A temporal mismatch was observed for mat area and prokaryote-based organics to P. johnsoni population flux in a ―tracking inertia‖ manner. 2 Acknowledgements It is difficult to express sufficient gratitude to my supervisor Dr. Vladimir Yurkov for his unfaltering patience, generosity and motivation throughout this entire degree. -

HEINZ SCHLESNER," CHRISTINA BARTELS, MANUEL SITTIG, MATTHIAS DORSCH, AND ERKO STACKEBRANDTT Institut fur Allgemeine Mikrobiologie, Christian-Albrecht-Universitat, 2300 Kiel, Federal Republic of Germany Four strains of budding, hyphal bacteria, which had very similar chemotaxonomic properties, were isolated from the Baltic Sea. The results of DNA-DNA hybridization experiments, indicated that three of the new isolates were closely related, while the fourth was only moderately related to the other three. Sequence signature and higher-order structural detail analyses of the 16s rRNA of strain IFAM 141gT (T = type strain) indicated that this isolate is related to the alpha subclass of the class Proteobacteriu. Although our isolates resemble members of the genera Hyphomicrobium and Hyphomonas in morphology, assignment to either of these genera was excluded on the basis of their markedly lower DNA guanine-plus-cytosine contents. We propose that these organisms should be placed in a new genus, Hirschiu baltica is the type species of this genus, and the type strain of H. bdtica is strain IFAM 1418 (= DSM 5838). Since the first description of a hyphal, budding bacterium, no1 and formamide were tested at concentrations of 0.02 and Hyphomicrobium vulgare (53), only the following additional 0.1% (vol/vol).

Here we have performed detailed characterization of the strain, and have found that it represents a novel genus. The 16S rRNA sequence of strain HD-1 displayed highest similarity to various uncultured species (86.7V99.7%), along with 86.2V88.2% similarity to sequences from Azospirillum, Methylobacterium, Rhizobium, and Hyphomicrobium, all members of the K-Proteobacteria. Phylogeneticanalysis revealed that HD-1 represented a deep-branched lineage among the K-Proteobacteria. DNA^DNA hybridization analysis with Azospirillum lipoferum and Hyphomicrobium vulgare revealed low levels of similarity among the strains. We further examined the biochemical properties of the strain under aerobic conditions. -

Etruscan tombs, many of which are subterranean, are one of the best representations of this culture. The principal importance of these tombs, however, lies in the wall paintings and in the tradition of rich burial, which was unique in the Mediterranean Basin, with the exception of Correspondence and Egypt. Relatively little information is available concerning the biodeterioration of Etruscan tombs, which is caused by a colonisation that covers the paintings with white, circular to irregular aggregates of bacteria or requests for materials biofilms that tend to connect each other. Thus, these colonisations sometimes cover extensive surfaces. Here should be addressed to we show that the colonisation of paintings in Tomba del Colle is primarily due to bacteria of the order C.S.-J. -

Lists of Names of Prokaryotic Candidatus Taxa

Garrity2,3, Charles T. Parker3, Maria Chuvochina4 and Martha E. Trujillo5 Abstract We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks between subspecies and class, pro- posed between the mid- 1990s, when the provisional status of Candidatus taxa was first established, and the end of 2018. Where necessary, corrected names are proposed that comply with the current provisions of the International Code of Nomenclature of Prokaryotes and its Orthography appendix. These lists, as well as updated lists of newly published names of Candidatus taxa with additions and corrections to the current lists to be published periodically in the International Journal of Systematic and Evo- lutionary Microbiology, may serve as the basis for the valid publication of the Candidatus names if and when the current propos- als to expand the type material for naming of prokaryotes to also include gene sequences of yet-uncultivated taxa is accepted by the International Committee on Systematics of Prokaryotes.

Mitigating Biofouling on Reverse Osmosis Membranes Via Greener Preservatives

Supervisory Committee Mitigating biofouling on reverse osmosis membranes via greener preservatives by Anna Curtin Biology (BSc), Le Moyne College, 2017 Supervisory Committee Heather Buckley, Department of Civil Engineering Supervisor Caetano Dorea, Department of Civil Engineering, Civil Engineering Departmental Member ii Abstract Water scarcity is an issue faced across the globe that is only expected to worsen in the coming years. We are therefore in need of methods for treating non-traditional sources of water. One promising method is desalination of brackish and seawater via reverse osmosis (RO). RO, however, is limited by biofouling, which is the buildup of organisms at the water-membrane interface. Biofouling causes the RO membrane to clog over time, which increases the energy requirement of the system. Eventually, the RO membrane must be treated, which tends to damage the membrane, reducing its lifespan. Additionally, antifoulant chemicals have the potential to create antimicrobial resistance, especially if they remain undegraded in the concentrate water. Finally, the hazard of chemicals used to treat biofouling must be acknowledged because although unlikely, smaller molecules run the risk of passing through the membrane and negatively impacting humans and the environment.
