Book Description
This book is devoted to nanomicrobiology and the nanosystems of bacteria. The initial chapter discusses some of the controversies in the geochemical and biomedical fields associated with the reports of nanobacteria in the environment. Current knowledge of several internal and surface structures of bacteria is addressed in this book. Included are chapters discussing carboxysomes, S-layers, gliding motility of bacteria, and aggregation of iron to produce nano-magnetite. Information about the activities of outer membrane vesicles produced by Gram-negative bacteria is discussed as a benefit to bacteria that produce it and some potential industrial applications are presented. A broad review of bacterial-mineral interactions is addressed in a chapter of metallic nanoparticles and colloids production by bacterial reduction of soluble redox active elements. The structures of bacterial nanowires are discussed and their application in extra-cellular electron transport is reviewed. Nanomotor activities of bacteria are discussed as pertains to the mechanics of flagellar rotation, production of energy by ATP synthase, DNA packing, and translocation of proteins across membranes by secretion systems. The rapidly evolving field of nanosystem technology is embracing many areas, and it is the hope that this book will stimulate the use of bacterial nanostructures for future developments in nanotechnology.

Book Description
Materials with features on the nanoscale date back hundreds of years, yet humans' ability to manipulate and control chemical systems on the atomistic level has grown immensely, particularly over the last 50 years. With expanded research capabilities, the use of nanotechnology in commercial products is also increasing, from quantum dots in television screens to novel battery materials for electric vehicles. However, along with commercialization, the risk of inadvertent release of these materials into the environment arises as well. Ecologically vital biological systems in the environment are subsequently suspectable to interaction with nanomaterials which could potentially result in harm. There are a number of complex factors associated with studying the interface between nanoparticles and cells, including nanoparticle core material, size, shape, functionalization, and transformation of the material during environmental exposure, as well as biological cell type, size, shape, and cell surface composition. As the cell membrane is likely to be the first point of contact between a cell and nanomaterial, the bacterial cell surface was modeled using phospholipids and other surface components from Gram-positive and Gram-negative bacteria. We investigated (1) cationic polymer interaction with supported lipid bilayers, as nanoparticles are often functionalized with analogous positively charged chemical groups, (2) branched polyethylenimine functionalized nanoparticle interaction with peptidoglycan and wall teichoic acids of strains of Gram-positive bacteria that differ in their wall teichoic acid composition, and (3) positively charged nanoparticle interaction with lipopolysaccharide (LPS)-containing supported lipid bilayers containing either smooth or rough LPS molecules from Escherichia coli. Using techniques sensitive to membrane surface adsorption, including quartz crystal microbalance with dissipation monitoring (QCM-D) and solid-state nuclear magnetic resonance (NMR) spectroscopy, our results demonstrate interactions between nanoparticles and cell surface structures depend on factors including electrostatic interactions, cell surface rigidity, as well as specific chemical groups present on the polycations, nanoparticles, and cell surface components. In studying the nano-bio interface on the molecular-level, the underlying goal of this research is to maintain benefit from the unique properties of nanomaterials, while reducing inadvertent negative consequences to biological systems.

Book Description
Tuberculosis continues to kills more people than any other single infective agent. The resurgence of the disease in many countries has produced a heightened awareness of the threat posed by mycobacterial infections. At the same time, there has been an explosion of knowledge of the fundamental properties of mycobacteria, most notably the determination of the complete genome sequence of Mycobacterium tuberculosis. This book provides an up-to-date account of these developments in the molecular biology and immunology of mycobacteria, coupled with allied advances of a more applied nature, such as the use of molecular techniques for diagnosis and epidemiological investigations. With chapters contributed from an international team of experts, it will not only be an essential reference text for the expanding mycobacterial research community, but also will find a prominent place on the shelves of clinicians, infectious disease and public health specialists, diagnostic laboratories, postgraduate students and indeed anyone concerned with the management and investigation of outbreaks of tuberculosis. Comprehensively covers recent advances in the molecular biology of the mycobacteria. First book to be published on this subject since the publishing of the complete genome for the tubercle bacillus (M. tuberculosis). Coincides with a worldwide resurgence of tuberculosis.

Book Description
Nanostructures for Antimicrobial Therapy discusses the pros and cons of the use of nanostructured materials in the prevention and eradication of infections, highlighting the efficient microbicidal effect of nanoparticles against antibiotic-resistant pathogens and biofilms. Conventional antibiotics are becoming ineffective towards microorganisms due to their widespread and often inappropriate use. As a result, the development of antibiotic resistance in microorganisms is increasingly being reported. New approaches are needed to confront the rising issues related to infectious diseases. The merging of biomaterials, such as chitosan, carrageenan, gelatin, poly (lactic-co-glycolic acid) with nanotechnology provides a promising platform for antimicrobial therapy as it provides a controlled way to target cells and induce the desired response without the adverse effects common to many traditional treatments. Nanoparticles represent one of the most promising therapeutic treatments to the problem caused by infectious micro-organisms resistant to traditional therapies. This volume discusses this promise in detail, and also discusses what challenges the greater use of nanoparticles might pose to medical professionals. The unique physiochemical properties of nanoparticles, combined with their growth inhibitory capacity against microbes has led to the upsurge in the research on nanoparticles as antimicrobials. The importance of bactericidal nanobiomaterials study will likely increase as development of resistant strains of bacteria against most potent antibiotics continues. - Shows how nanoantibiotics can be used to more effectively treat disease - Discusses the advantages and issues of a variety of different nanoantibiotics, enabling medics to select which best meets their needs - Provides a cogent summary of recent developments in this field, allowing readers to quickly familiarize themselves with this topic area

Book Description
This book provides an in-depth overview on the manifold functions of fungal extracellular vesicles (EV) which span from cell-to-cell communication, pathogenicity and stimulation of host’s immunity to export of hundreds of biomolecules. The book summarizes the present knowledge on the impact of extracellular vesicles on fungal biology. Extracellular vesicles participate in fundamental biological processes in all living cells but only during the last 15 years the production and functions of EVs were identified and studied in fungal species too. Up to date more than 50 independent studies have shown that extracellular vesicles are produced by at least 20 fungal species. The book addresses researchers and advanced students in Microbiology, Mycology and Biotechnology.
