Although interactions between nanoparticles and microorganisms in the environment are unavoidable and commonplace, it is still not clear what potential effects they may have. Metallic Nanocrystallites and their Interface with Microbial Systems not only illustrates how microbes and these particular nanoparticles interact but also it describes the consequences of these interactions. This brief discusses the impact of gold, silver, zinc oxide, and cerium oxide nanoparticles on the growth and viability of both Gram-negative and Gram-positive bacterium. Moreover, it analyses the relationship between bacterial growth inhibition, reactive oxygen species generation, the regulation of transcriptional stress genomes, and the toxicity of these materials. Finally, it reviews the specific metallic nanomaterials and highlights their modes of synthesis, reactivity at surfaces, and the importance of assay procedures in determining their toxicity levels. Various microscopy techniques used to determine their mechanisms of action are also presented. Metallic Nanocrystallites and their Interface with Microbial Systems will be a valuable source to the scientific and industrial community as well as to students and researchers in microbiology, biotechnology, nanotechnology, toxicology, materials science, biomedical engineering, cell and molecular biology.

This book, Functional Nanocomposites and Their Applications, explains innovative developments in nanocomposites. It covers novel findings and various applications of nanocomposites in different emerging fields. Chapters cover several types of nanocomposites as well as their synthesis, manufacturing, characteristics, and applications. Special emphasis is given to innovative works on functional nanocomposites and their relevant areas of use. The authors depict the stability and functionality of nanocomposites and their applications in various sectors, such as industrial, structural, biomedical, etc. Nanocomposites in wastewater treatment, MnO2 and graphene nanostructures, computer modeling of structure and mechanical behavior, polythiophene nanocomposites, and other topics are covered in the chapters. Nanocomposites have a high surface-to-volume ratio and hence have strong mechanical characteristics, making them suitable for application in the automotive and construction sectors. Nanocomposites show better property enhancement over conventional composites i.e., properties such as electrical, thermal, mechanical, and barrier. They have good transparency and also reduce the property of flammability. Other uses include power tool housing, electronic covers, and so forth. This book will help readers easily understand the effective implementation of different types of nanocomposites, such as for environmental remediation, biomedical applications, lightweight designed goods with better mechanical, thermal, or chemical resistance qualities, etc. This book will be valuable for scientists and engineers both in academics and industry.

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.

Microbe Mediated Remediation of Environmental Contaminants presents recent scientific progress in applying microbes for environmental management. The book explores the current existing practical applications and provides information to help readers develop new practices and applications. Edited by recognized leaders in the field, this penetrating assessment of our progress to date in deploying microorganisms to the advantage of environmental management and biotechnology will be widely welcomed by those working in soil contamination management, agriculture, environment management, soil microbiology, and waste management. The polluting effects on the world around us of soil erosion, the unwanted migration of sediments, chemical fertilizers and pesticides, and the improper treatment of human and animal wastes have resulted in serious environmental and social problems around the world, problems which require us to look for solutions elsewhere than established physical and chemical technologies. Often the answer lies in hybrid applications in which microbial methods are combined with physical and chemical ones. When we remember that these highly effective microorganisms, cultured for a variety of applications, are but a tiny fraction of those to be found in the world around us, we realize the vastness of the untapped and beneficial potential of microorganisms. - Explores microbial application redressing for soil and water contamination challenges - Includes information on microbial synthesized nanomaterials for remediation of contaminated soils - Presents a uniquely hybrid approach, combining microbial interactions with other chemical and physical methods
