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
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
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.

Book Description
Following an introduction to biogenic metal nanoparticles, this book presents how they can be biosynthesized using bacteria, fungi and yeast, as well as their potential applications in biomedicine. It is shown that the synthesis of nanoparticles using microbes is eco-friendly and results in reproducible metal nanoparticles of well-defined sizes, shapes and structures. This biotechnological approach based on the process of biomineralization exploits the effectiveness and flexibility of biological systems. Chapters include practical protocols for microbial synthesis of nanoparticles and microbial screening methods for isolating a specific nanoparticle producer as well as reviews on process optimization, industrial scale production, biomolecule-nanoparticle interactions, magnetosomes, silver nanoparticles and their numerous applications in medicine, and the application of gold nanoparticles in developing sensitive biosensors.
