This book was released on 2012-12-06 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystalline surface layers (S-layers) represent an almost universal feature of archaebacterial cell envelopes and can be found in gram-positive and gram-negative eubacterial species from nearly all phylogenetic branches. S-layers consist of a single protein- or glycoprotein species and thus can be considered as one of the most primitive membrane structures developed during evolution. Prokaryotes carrying S-layers are ubiquitously found in every part of the biosphere. This supports the concept of a general supramolecular "porous crystalline surface layer" fulfilling a broad spectrum of functions which are strongly dependent on the particular environmental and ecological conditions. Their structural simplicity makes S-layers a suitable model for analyzing structure-function relationships as well as dynamic aspects of membrane morphogenesis.

Download or read book The Biology of Acinetobacter written by K.J. Towner and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1st International Workshop on Acinetobacter was held on 6th September, 1986, in Manchester, England, in association with the 14th International Congress of Microbiology. That occasion was so well attended and productive that there were soon discussions about how, when and where the next meeting should be held. This time, however, there was sufficient confidence to think of a more substantial meeting and to plan for the proceedings to be published. It emerged that there was wide agreement that the time was ripe to take stock of the entire biology of Acinetobacter: its occurrence and taxonomy; its molecular biology, biochemistry and physiology; its clinical importance and its industrial and commercial applications. The 2nd International Workshop on Acinetobacter took place from 6th to 7th September, 1990, at the Institut Pasteur, Paris, and was sponsored by the Federation of European Microbiological Societies. There were about 100 participants from 19 countries. The backbone of the meeting consisted of 23 plenary lectures. There were 28 posters and the meeting closed with a general discussion which went on long after the official finishing time despite all the counter-attractions of a sunny Parisian Friday afternoon. Indeed discussions continued while cruising along the Seine and while dining at the top of the Tour Montparnasse. However, the vitality and usefulness of even the most successful meeting is difficult to transmit by the printed word.

Download or read book General Microbiology written by Linda Bruslind and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welcome to the wonderful world of microbiology! Yay! So. What is microbiology? If we break the word down it translates to "the study of small life," where the small life refers to microorganisms or microbes. But who are the microbes? And how small are they? Generally microbes can be divided in to two categories: the cellular microbes (or organisms) and the acellular microbes (or agents). In the cellular camp we have the bacteria, the archaea, the fungi, and the protists (a bit of a grab bag composed of algae, protozoa, slime molds, and water molds). Cellular microbes can be either unicellular, where one cell is the entire organism, or multicellular, where hundreds, thousands or even billions of cells can make up the entire organism. In the acellular camp we have the viruses and other infectious agents, such as prions and viroids. In this textbook the focus will be on the bacteria and archaea (traditionally known as the "prokaryotes,") and the viruses and other acellular agents.

Download or read book Curiosity And Passion For Science And Art written by Uwe B Sleytr and published by World Scientific. This book was released on 2016-07-04 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the accomplishments of a curious and imaginative scientist, and his endeavours to translate or even to extrapolate scientific insights into the world of art.The science section in this volume concerns studies on S-layers, a very important class of proteins found on the surface of numerous Bacteria and nearly all Archaea. S-layer proteins are one of the most abundant biopolymers on our planet, and assemble into the simplest type of biological membrane. Moreover, they are unique building blocks and patterning elements for the production of complex supramolecular structures and nanoscale devices in nanobiotechnology, molecular nanotechnology, synthetic biology, biomimetics and nanomedicine.In the second part of this book the author goes on to passionately describe how his scientific activities stimulated his art work, which in particular concerns the visualization of results and the potential of synthetic biology and evolutionary events induced by genetic manipulations. Most importantly, the engagement in art allowed him to leave the rather curtailed canon of science and reach a mental state of unlimited freedom of thoughts. Mask-like sculptures are used as examples to visualize the intersection between science and art, and in particular the unpredictability and mystery of scientific visions.
Download or read book Prokaryotic Cell Wall Compounds written by Helmut König and published by Springer Science & Business Media. This book was released on 2010-03-18 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial cell wall structures play a significant role in maintaining cells’ shape, as protecting layers against harmful agents, in cell adhesion and in positive and negative biological activities with host cells. All prokaryotes, whether they are bacteria or archaea, rely on their surface polymers for these multiple functions. Their surfaces serve as the indispensable primary interfaces between the cell and its surroundings, often mediating or catalyzing important interactions. Prokaryotic Cell Wall Compounds summarizes the current state of knowledge on the prokaryotic cell wall. Topics concerning bacterial and archaeal polymeric cell wall structures, biological activities, growth and inhibition, cell wall interactions and the applications of cell wall components, especially in the field of nanobiotechnology, are presented.

Download or read book A Multi scale Examination of Protein Surface Layer Assembly and Function in Bacteria and Archaea written by Jonathan Robert Herrmann and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface layers (S-layers) are nanoporous shells of crystalline protein surrounding a great diversity of bacteria and nearly all known archaea. As the outermost component of the cell envelope, S-layers are one of the most abundant biopolymers on earth and are implicated in functions ranging from providing the structural integrity of the cell to mediating host-pathogen interactions. In this thesis, I report a multi-scale analysis of S-layers from the model bacterium Caulobacter crescentus and a more recently cultivated thaumarchaeote, Nitrosoarchaeum limnia. By first biophysically characterizing the S-layer protein (SLP) from C. crescentus, RsaA, I discovered that environmental calcium mediates multiple physical states of the S-layer. I leveraged this knowledge to reconstitute and specifically image S-layer assembly in living cells. Super-resolution fluorescence microscopy and single-molecule tracking demonstrated that remarkably fast and efficient continuous 2D protein crystallization governs S-layer self-assembly. I further examined the rapid 2D crystallization of RsaA using a combination of time-resolved small angle x-ray scattering (SAXS) and electron cryo-microscopy (Cryo-EM). These observations revealed that a multi-step crystallization pathway involving a short-lived crystalline intermediate is responsible for rapid self-assembly of RsaA. Robust S-layer lattice formation has implications for essential cell functions such as energy production, which in the ammonia-oxidizing archaeaon N. limnia likely occurs within the pseudo-periplasmic space between the cell's only lipid membrane and the extracellular S-layer. Electrodiffusion simulations of the N. limnia cell envelope suggest that the S-layer facilitates diffusion of its main energy source, ammonium ions, through the nanopores of the S-layer by creating a charged protein surface. As such, we propose ion transport as an evolutionary basis for conservation of charged amino acids among archaeal SLPs. Taken together, these findings inform the development of antibiotics mediating S-layer biology and provide insight into possible avenues to design biologically inspired self-assembling macromolecular nanomaterials.

Book excerpt: As a group of organisms that are too small to see and best known for being agents of disease and death, microbes are not always appreciated for the numerous supportive and positive contributions they make to the living world. Designed to support a course in microbiology, Microbiology: A Laboratory Experience permits a glimpse into both the good and the bad in the microscopic world. The laboratory experiences are designed to engage and support student interest in microbiology as a topic, field of study, and career. This text provides a series of laboratory exercises compatible with a one-semester undergraduate microbiology or bacteriology course with a three- or four-hour lab period that meets once or twice a week. The design of the lab manual conforms to the American Society for Microbiology curriculum guidelines and takes a ground-up approach -- beginning with an introduction to biosafety and containment practices and how to work with biological hazards. From there the course moves to basic but essential microscopy skills, aseptic technique and culture methods, and builds to include more advanced lab techniques. The exercises incorporate a semester-long investigative laboratory project designed to promote the sense of discovery and encourage student engagement. The curriculum is rigorous but manageable for a single semester and incorporates best practices in biology education.
