Available in PDF, EPUB and Kindle. Book excerpt: Bacterial surface or secreted polysaccharides are molecules that can function as barriers to protect bacterial cells against environmental stresses, as well as act as adhesins or recognition molecules. In some cases, these molecules are immunodominant antigens eliciting a vigorous immune response, while in other cases the expression of polysaccharides camouflages the bacteria from the immune system. Until recently, most studies on the enzymatic steps and regulation of these molecules were performed on the enteric gram negative bacteria Escherichia coli and Salmonella typhimurium. With the advent of modern bacterial genetics, techniques such as construction and characterization of polysaccharide mutants, cloning of genes and complementation of these mutations, and expression of polysaccharides in heterologous bacterial hosts has prompted investigations into the roles and functions of these molecules for many different bacteria. Here, we present the genetic analysis of polysaccharides from a number of bacteria pathogenic to humans and one symbiotic with plants in hopes that similarities in the experimental approaches as well as finding s from such investigations may lead to a general understanding of polysaccharide synthesis and regulation in various bacteria.

Available in PDF, EPUB and Kindle. Book excerpt: Many bacteria, such as certain Neisseria and Haemophilus or Escherichia coli, are able to withstand the bactericidal activity of complement and phagocytes. This bacterial self protection is brought about by encapsulation. Bacterial capsules thus enable the pathogenic bacteria to survive in the host by counter action or evasion of the nonspecific host defense in the early pre immune phase of an infection. It is only in the late immune phase of the infection, when specific anticapsular antibodies are formed and enforce the host's defense system, that this protective action is overcome. Encapsulated bacteria are then killed and eliminated. Interestingly, some capsules can not or only inefficiently be handled by the immune system. The ensuing lack of antibody formation results in a prolonged susceptibility of the host to the pathogenic bacteria exhibiting such capsules. It was found that bacterial capsules consist of acidic poly saccharides. From this it followed that the role of the capsules in the interaction of encapsulated bacteria with the host may be due to the chemistry of the capsular polysaccharides. This led to intensive studies of capsular polysaccharides in many laboratories. Our increasing knowledge of the structural features of capsular polysaccharides prompted not only immuno chemical studies analyzing the interactions of these poly saccharide antigens and characterizing the epitopes, but also investigations into their biosynthesis. These studies were complemented and supported by genetic analyses. Today many interdisciplinary investigations of capsular polysaccharides are in progress.

Download or read book Polysaccharides written by Gerald O. Aspinall and published by Elsevier. This book was released on 2016-07-29 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polysaccharides provides information pertinent to the fundamental aspects of the chemistry of polysaccharides. This book discusses the methods used for the isolation, purification, and structural determination of the various types of polysaccharide. Organized into 14 chapters, this book begins with an overview of the almost universal occurrence of natural macromolecules in living organisms where they form a variety of functions. This text then examines the isolation of polysaccharides, which involves solubilization in aqueous solvents or in dipolar aprotic solvents. Other chapters consider the industrial applications of polysaccharides and of their derivatives. This book discusses as well the procedure for the isolation of wood polysaccharides, which involves the preparation of a holocellulose by the selective solubilization of the lignin. The final chapter deals with the classes of complex natural polymers in which the nature of the linkage of sugar units to other structural units have been established. This book is a valuable resource for biologists.

Book excerpt: Microbial polysaccharides represent an attractive alternative to those from plants or macro algae. They can be produced from renewable sources including lignocellulosic waste streams. Their production does not depend on geographical constraints and/or seasonal limitations. Additionally the manipulation of biosynthetic pathways to enhance productivity or to influence the chemical polysaccharide composition is comparatively easy in bacteria. Microbial exopolysaccharides represents a valuable resource of biogenic and biodegradable polymers, suitable to replace petro based polymers in various technical applications. Furthermore, biocompatible exopolysaccharides are very attractive in medical applications, such as drug delivery systems, use as vaccines or nanoparticles. This research topic will depict the status quo, as well as the future needs in the field of EPS and biofilm research. Starting from the unexplored diversity of microbial polysaccharide producers to production processes and possibilities for modifications, to enhance the already high number of functionalities based on the chemical structures. An overview of the recent and future applications will be given, and the necessity in unravelling the biosynthesis of microbial exopolysaccharide producers is depicted, highlighting the future trend of tailor made polymers. Constraints in structure analysis of these highly complex biogenic polymers are described and different approaches to solve the restrictions in imaging and NMR analysis will be given. Therefore; this research topic comprises the whole process from genes to applications.

Available in PDF, EPUB and Kindle. Book excerpt: The complex world of polysaccharides is a compilation of the characteristics of a variety of polysaccharides from plants, animals and microorganisms. The diversity of these polysaccharides arises from the structural variations and the monosaccharide content which is under genetic control. The chemical and physical properties have made them useful in many pharmaceutical, food and industrial applications. These properties of the polysaccharides determine their biological activity and their function in various applications. The role played by polysaccharides in preservation and protection of food, as carriers of nutrients and drugs, their ability to interact with molecules both for efficient delivery as well as improving textures of food colloids and their use as therapeutics are some of the functions discussed.
