Book excerpt: This book introduces Planctomycetes bacteria and deals in detail with their unusual structure, physiology, genomics and evolutionary significance. It is a definitive summary of recent knowledge of this important distinctive group of bacteria, microorganisms which challenge our very concept of the bacterium. Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria, including verrucomicrobia and chlamydia, challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full diversity of how living cells can be organized internally. Unique among bacteria, they include species possessing cells with intracellular membrane-bounded compartments and a peptidoglycan-less cell wall, and bacteria such as the anammox organisms performing unique anaerobic ammonium oxidation significant for global nitrogen cycle.

This book was released on 2019-10-02 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Planctomycetes, Verrucomicrobia, Chlamydiae (PVC) and related phyla have recently emerged as fascinating subjects for research in evolutionary cell biology, ecology, biotechnology, evolution and human health. This interest is prompted by particular characteristics observed in the PVC superphylum that are otherwise rarely observed in bacteria but are however still poorly described or understood, such as the presence of a complex endomembrane system, or compacted DNA throughout most of the cell cycle. Therefore, the members of the PVC superphylum represent an excellent example of the value of studying bacteria other than ‘classical’ models.

Download or read book Intra and inter species interactions in microbial communities written by Luis Raul Comolli and published by Frontiers Media SA. This book was released on 2015-03-03 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in various “OMICs” fields have revolutionized our understanding of the vast diversity and ubiquity of microbes in the biosphere. However, most of the current paradigms of microbial cell biology, and our view of how microbes live and what they are capable of, are derived from in vitro experiments on isolated strains. Even the co-culturing of mixed species to interrogate community behavior is relatively new. But the majority of microorganisms lives in complex communities in natural environments, under varying conditions, and often cannot be cultivated. Unless we obtain a detailed understanding of the near-native 3D ultrastructure of individual community members, the 3D spatial community organization, their metabolic interdependences, coordinated gene expression and the spatial organization of their macromolecular machines inventories as well as their communication strategies, we won’t be able to truly understand microbial community life. How spatial and also temporal organization in cell–cell interactions are achieved remains largely elusive. For example, a key question in microbial ecology is what mechanisms microbes employ to respond when faced with prey, competitors or predators, and changes in external factors. Specifically, to what degree do bacterial cells in biofilms act individually or with coordinated responses? What are the spatial extent and coherence of coordinated responses? In addition, networks linking organisms across a dynamic range of physical constraints and connections should provide the basis for linked evolutionary changes under pressure from a changing environment. Therefore, we need to investigate microbial responses to altered or adverse environmental conditions (including phages, predators, and competitors) and their macromolecular, metabolic responses according to their spatial organization. We envision a diverse set of tools, including optical, spectroscopical, chemical and ultrastructural imaging techniques that will be utilized to address questions regarding e.g. intra- and inter-organism interactions linked to ultrastructure, and correlated adaptive responses in gene expression, physiological and metabolic states as a consequence of the alterations of their environment. Clearly strategies for co-evolution and in general the display of adaptive strategies of a microbial network as a response to the altered environment are of high interest. While a special focus will be placed on terrestrial sole-species or mixed biofilms, we are also interested in aquatic systems, biofilms in general and microbes living in symbiosis. In this Research Topic, we wish to summarize and review results investigating interactions and possibly networks between microbes of the same or different species, their co-occurrence, as well as spatiotemporal patterns of distribution. Our goal is to include a broad spectrum of experimental and theoretical contributions, from research and review articles to hypothesis and theory, aiming at understanding microbial interactions at a systems level.
Download or read book Microbiology of wetlands written by Paul Bodelier and published by Frontiers E-books. This book was released on 2013-07-08 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Watersaturated soil and sediment ecosystems (i.e. wetlands) are ecologically as well as economically important systems due to their high productivity, their nutrient (re)cycling capacities and their prominent contribution to global greenhouse gas emissions. Being on the transition between terrestrial and – aquatic ecosystems, wetlands are buffers for terrestrial run off thereby preventing eutrophication of inland as well as coastal waters. The close proximity of oxic-anoxic conditions, often created by wetland plant roots, facilitates the simultaneous activity of aerobic as well as anaerobic microbial communities. Input of nutrients and fast recycling due to active aerobes and anaerobes makes these systems highly productive and therefore attractive for humans as well as many other organisms. Wetlands globally are under high pressure due to anthropogenic activities as well as climate change. Changes of land-use as well as altered hydrology due to climate change will lead to disturbance and loss of these habitats. However, the diversity and functioning of microbial communities in wetlands systems in highly underexplored in comparison to soils and aquatic ecosystems. Given the importance of wetlands and their immediate threats combined with the lack of knowledge on the microbiology of these systems is the basis for this special issue, focusing on the current microbiological knowledge and gaps therein to be assessed in future wetland research. Papers (research papers, reviews, perspectives, opinion papers) are welcomed that focus on all aspects that regulate the functioning and community composition of microbes (i.e. bacteria, archaea, protozoa, fungi) in wetland ecosystems (peat, coastal as well as freshwater marshes, flood plains, rice paddies, littoral zones of lakes etc) from all geographic regions. Welcomed topics are physiology, ecology, functioning, biodiversity, biogeography of microbes involved in nutrient cycling (C, N, P, Fe, Mn), green house gas emissions as well as plant-microbe interactions. These studies can be multidisciplinary and cover topics from the molecular to the community level.

Download or read book Size Limits of Very Small Microorganisms written by National Research Council and published by National Academies Press. This book was released on 1999-10-13 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.
Download or read book Principles of Microbial Diversity written by James W. Brown and published by John Wiley & Sons. This book was released on 2014-12-01 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every speck of dust, drop of water, and grain of soil and each part of every plant and animal contain their own worlds of microbes. Designed as a key text for upper-level undergraduates majoring in microbiology, genetics, or biology, Principles of Microbial Diversity provides a solid curriculum for students to explore the enormous range of biological diversity in the microbial world. Within these richly illustrated pages, author and professor James W. Brown provides a practical guide to microbial diversity from a phylogenetic perspective in which students learn to construct and interpret evolutionary trees from DNA sequences. He then offers a survey of the "tree of life" that establishes the necessary basic knowledge about the microbial world. Finally, the author draws the student's attention to the universe of microbial diversity with focused studies of the contributions that specific organisms make to the ecosystem. Principles of Microbial Diversity fills an empty niche in microbiology textbooks by providing an engaging, cutting-edge view of the "microbial zoo" that exists around us, covering bacteria, archaea, eukaryotes, and viruses.

Download or read book Developmental Biology in Prokaryotes and Lower Eukaryotes written by Tomás González Villa and published by Springer Nature. This book was released on 2021-07-31 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘Developmental biology’ is widely understood as processes, which mainly concern embryonic animal development and differentiation of cells and tissue. It is also often defined as the timeline for the evolutionary developmental biology of eukaryotic multicellular higher organisms, i.e., plants and animals. The development of prokaryotes and lower eukaryotes in contrary has been neglected for a long time, which was the motivation for publishing this book. This book highlights one of Darwin's most important findings: Evolution is a creative, but not a conscious process. It also illustrates that this concept does not only apply to multicellular higher organisms, but affects every form of life. The reader shall find complex biochemical and genetic pathways of bacteria, yeasts or protozoa, comparable to those exhibited by plants or animals. The molecular mechanisms of dramatic genome rearrangements, recombination and horizontal gene transfer that are responsible for evolutionary adaptations are discussed. Additionally, the book covers bacteria of the genera Myxobacteriales and Caulobacterales, which are able to develop tissue-like cellular organization. The morphogenesis of entomopathogenic fungi and the endosymbiont theory are also addressed. The book is a useful introduction to the field for junior scientists, interested in bacteriology, protistology and fungal development. It is also an interesting read for advanced scientists, giving them a broader view of the field beyond their area of specialization.
