Download or read book Microbial Symbiosis of Marine Sessile Hosts Diversity Function and Applications written by Suhelen Egan and published by Frontiers Media SA. This book was released on 2015-12-21 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern molecular -omics tools (metagenomics, metaproteomics etc.) have greatly contributed to the rapid advancement of our understanding of microbial diversity and function in the world’s oceans. These tools are now increasingly applied to host-associated environments to describe the symbiotic microbiome and obtain a holistic view of marine host-microbial interactions. Whilst all eukaryotic hosts are likely to benefit from their microbial associates, marine sessile eukaryotes, including macroalgae, seagrasses and various invertebrates (sponges, acidians, corals, hydroids etc), rely in particular on the function of their microbiome. For example, marine sessile eukaryotes are under constant grazing, colonization and fouling pressure from the millions of micro- and macroorganisms in the surrounding seawater. Host-associated microorganisms have been shown to produce secondary metabolites as defense molecules against unwanted colonization or pathogens, thus having an important function in host health and survival. Similarly microbial symbionts of sessile eukaryotes are often essential players in local nutrient cycling thus benefiting both the host and the surrounding ecosystem. Various research fields have contributed to generating knowledge of host-associated systems, including microbiology, biotechnology, molecular biology, ecology, evolution and biotechnology. Through a focus on model marine sessile host systems we believe that new insight into the interactions between host and microbial symbionts will be obtained and important areas of future research will be identified. This research topic includes original research, review and opinion articles that bring together the knowledge from different aspects of biology and highlight advances in our understanding of the diversity and function of the microbiomes on marine sessile hosts.

Book excerpt: Marine microbes are uniquely important to life as we know it. Since life most likely began in the oceans, marine microorganisms are the closest living descendants of the original forms of life. They are also major pillars of the biosphere. Their unique metabolisms allow marine microbes to carry out many steps of the biogeochemical cycles that other organisms are unable to complete. The smooth functioning of these cycles is necessary for life to continue on earth. Early marine microorganisms also helped create the conditions under which subsequent life developed. More than two billion years ago, the generation of oxygen by photosynthetic marine microorganisms helped shape the chemical environment in which plants, animals, and all other life forms have evolved. A great deal of research on the biogeography of marine microorganisms has been carried out, but many unknowns persist, and more work is needed to elucidate and understand their complexity. It is now known that microorganisms live in every corner of the oceans. Their habitats are diverse and include open water, sediment, bodies of marine macro- and microorganisms, estuaries, and hydrothermal vents. By studying these habitats, scientists have developed a limited ability to predict the composition of marine microbial communities. It has also been found that some marine microbes have more cosmopolitan distributions than others. Recent work has found that most of the ecological principles that apply to larger organisms can also be applied to microorganisms, including marine microbes, but there are exceptions. Almost every ecophysiological parameter in the oceans is thought to have an impact on the diversity of microbial communities. Most of the direct interactions marine microorganisms have with larger organisms fall into one of two broad categories: symbiosis or pathogenesis. Beneficial microbial symbioses have enabled many invertebrate species to take advantage of habitats that would otherwise be unavailable to them. Invertebrates in these relationships may also enjoy the benefits of bioactive compounds microbes may produce to prevent bio-fouling or to ward off predators. Marine viruses are found in surprisingly high numbers in seawater, but it is likely that these populations are in equilibrium with their host populations. The metabolic diversity of marine microorganisms allows them to assume many roles in the biogeochemical cycles that other organisms cannot complete. Marine microbes are also able to adapt to the many extreme environments in the oceans. As humans continue to alter the environment, climate change will inevitably impact marine microbial communities and the biogeochemical cycles in which they participate, but the exact nature of these impacts cannot yet be predicted. Human health relies on a number of critical equilibria that marine microorganisms broker, including the balance between viruses and their hosts in the oceans, the balances that keep harmful algal blooms in check, the processes that control nutrient concentrations in marine waters, and others. The metabolic capabilities of marine microbes can be put to work in any number of biotechnology applications, including the manufacture of industrial products and energy production. Marine microbes are sources of novel bioactive compounds that may have application as pharmaceuticals. Potential applications for marine microorganisms in ameliorating environmental degradation also exist. Innovative approaches in research, education, and training are critical for moving the field of marine microbiology forward. Modern research in this field should embrace the new tools of genomics and metagenomics, but not to the exclusion of other methods of discovery. Education and training in marine microbiology needs to be multidisciplinary. Arrangements that expose graduate students and postdoctoral scientists to laboratories that do work outside the students' immediate fields of focus should be encouraged.

Download or read book The Marine Microbiome written by Lucas J. Stal and published by Springer. This book was released on 2016-06-03 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the state-of-the-art concerning the ‘marine microbiome’ and its uses in biotechnology. The first part discusses the diversity and ecology of marine microorganisms and viruses, including all three domains of life: Bacteria, Archaea, and Eukarya. It discusses whether marine microorganisms exist and, if so, why they might be unique. The second part presents selected marine habitats, their inhabitants and how they influence biogeochemical cycles, while the third discusses the utilization of marine microbial resources, including legal aspects, dissemination, and public awareness. The marine microbiome is the total of microorganisms and viruses in the ocean and seas and in any connected environment, including the seafloor and marine animals and plants. The diversity of microbial life remains unquantified and largely unknown, and could represent a hidden treasure for human society. Accordingly, this book is also intended to connect academics and industry, providing essential information for microbiologists from both fields.

Download or read book The Social Biology of Microbial Communities written by Institute of Medicine and published by National Academies Press. This book was released on 2013-01-10 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.

Download or read book Marine Microbial Diversity as a Source of Bioactive Natural Products written by Didier Stien and published by MDPI. This book was released on 2020-06-17 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: A trillion different microbial species have been evolving for some 3.5 billion years, producing ever more complex active secondary metabolites. The sea is a cauldron of a great diversity of useful and valuable compounds. This Special Issue focused on studies of marine microbe natural products for discovering compounds useful to humankind. Papers were collected that provide up-to-date information regarding the characterization of marine microbes’ metabolic diversity and the evaluation of the therapeutic potential of marine microbes’ metabolites. Most of the articles in this book deal with marine fungi, biological and chemical diversity, and their active metabolites. This may be a sign that marine fungi have been under studied to date and are perceived by many researchers as an important source of discovery in this field. A best practices guide for the isolation of marine fungi from different matrixes and their conservation is also presented. The comparison of the phylogenetic and metabolomic profiles of microalgae from different lineages provides novel insights into the potential of chemotaxonomy in marine phytoplankton, showing a good overlap of phylogenetic and chemotaxonomic signals.
Download or read book Diversity Form and Function Within the Marine Mammal Microbiota written by Natasha K. Dudek and published by . This book was released on 2018 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animals can be viewed as complex, co-evolving networks of microbes and host cells. Understanding the diversity, form, and function of microbes associated with different animals is therefore essential to understanding the patterns and processes underlying evolution across all domains of life. Extant marine mammals present an interesting opportunity to study the microbiota of animals with an unusual lifestyle that has arisen independently six times since the time of their last common ancestor. The manner in which the marine mammal-associated microbiota has evolved in response to the host's marine lifestyle remains unclear. In this thesis, I describe three studies of the microbiota of marine mammals. In the first, I characterize bacterial community composition associated with sea otters, which are a keystone species that is listed as endangered by the IUCN. They are also the sole representatives of an entire lineage of marine mammal. The findings suggest that environment plays a major role in structuring sea otter-associated bacterial community composition and raises the question of whether sea otters may have a reduced bacterial biomass in their guts compared to other mammals. As seen in other marine mammal species, results show that sea otters host a diversity of 'microbial dark matter'. In chapter two of this thesis, I study such 'microbial dark matter' present in the dolphin mouth and propose two new bacterial phyla (Candidatus Delphibacteria and Candidatus Fertabacteria), the former of which our metabolic reconstruction suggests may have a direct effect on dolphin physiology and health. In the third chapter of my thesis, I operate under the assumption that novel phylogenetic diversity is correlated with novel functional diversity, and thereby discover a previously uncharacterized rectangular microbe in dolphin oral samples with several unusual morphological features, such as pili-like appendages whose architecture differs substantially from known surface structures seen in bacteria and archaea. A single-cell genomics experiment suggested that this microbe was a type of bacteria from one of the following three groups: Bacteroidetes, TM7, or Epsilonproteobacteria. Collectively, these studies provide insight into diversity, form, and function within the marine mammal microbiota, and contribute towards our understanding of the microbial diversity, both phylogenetic and functional, which has evolved on Earth.

Download or read book Molecular Microbial Ecology written by Mark Osborn and published by Taylor & Francis. This book was released on 2004-06-02 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microoganisms are distributed across every ecosystem, and microbial transformations are fundamental to the operation of the biosphere. Microbial ecology is the study of this interaction between microorganisms and their environment, and arguably represents one of the most important areas of biological research. Yet for many years our study of microbial flora was severely limited: the primary method of culturing microorganisms on media allowed us to study only between 0.1 and 10% of the total microbial flora in any given environment. Molecular Microbial Ecology gives a comprehensive guide to the recent revolution in the study of microorganisms in the environment. Details are given on molecular methods for isolating some of the previously uncultured and numerically dominant microbial groups. PCR-based approaches to studying prokaryotic systematics are described, including ribosomal RNA analysis and stable isotope probing. Later chapters cover DNA hybridisation techniques (including fluorescent in situ hybridisation), as well as genomic and metagenomic approaches to microbial ecology. Gathering together some of the world’s leading experts, this book provides an invaluable introduction to the modern theory and molecular methods used in studying microbial ecology.
