Over fifty years of scientific and industrial developments focused on the amino acid producer bacterium Corynebacterium glutamicum has successfully yielded up to 2.93 and 1.95 million tons/year of L glutamic acid and L-lysine, respectively. As a result of this biotechnological effort, a massive amount of knowledge decidedly applicable to the development of new products has been gained. Nowadays, this knowledge is used to enlarge the portfolio of C. glutamicum industrial products, since they are highly relevant as chemicals, biodegradable polymers, ingredients, or additives in food, feed, cosmetics and pharmaceuticals. This book addresses production of these new metabolites (C. glutamicum applications) and their potential under the expert point of view of those groups directly involved in their developments. Thus, amino acids out of the traditional glutamic acid or lysine, as L valine; food colorants such as carotenoids; dicarboxylic acids used as building blocks (e.g: succinate); alpha hydroxy acids as L lactate, D lactate or glycolate; biodegradable polyester (eg.: polyhydroxybutyrate); alcohols for biofuel as isobutanol as well as bioremediation applications of the new developments around C. glutamicum described in this book. Those industrial relevant compounds come to the market parallel with the developing application of new technologies. Hence, cell activity as a whole by means of the Proteomics or Transcriptomics approaches, as well as the methodologies that mimic the large fermetor conditions in a scale-down format are also reviewed in the book. Additionally, a historical description and an updated review of the taxonomical environment of Corynebacterium genus open an essential manual for enterprises, researchers and academia involved in Actinobacteria, secondary metabolite production and industrial applications. This book reviews the evolution of almost sixty years of development, initially focused on amino acid production, which unleashes the idea of C. glutamicum as a biorefinery due to its ability to generate hundreds of products demanded by the market.

The book will provide an overview of the advancement of fundamental knowledge and applications of antimicrobial peptides in biomedical, agricultural, veterinary, food, and cosmetic products. Antimicrobial peptides stand as potentially great alternatives to current antibiotics, and most research in this newly-created area has been published in journals and other periodicals. It is the editors' opinion that it is timely to sum up the most important achievements in the field and provide the scientific community in a reference book. The goals of this project include illustrating the achievements made so far, debating the state of the art, and drawing new perspectives.

The U.S. Environmental Protection Agency (EPA) Office of Research and Development is striving to protect human health and the environment from adverse impacts resulting from acts of terror by investigating the effectiveness and applicability of technologies for homeland security (HS)-related applications. EPA has identified detection of pathogenic micro-organisms in environmental samples following a terrorist attack as a critical component of an effective response. Detection of such pathogens would require development and validation of sampling techniques that could be used by multiple laboratories following a homeland security event. The Centers for Disease Control and Prevention (CDC), part of the U.S. Department of Health and Human Services (DHHS), has extensive knowledge of potential biological hazards. In this book, CDC, in collaboration with EPA, developed and improved methods for extraction of Bacillus anthracis (BA) spores from soil. This book also investigates the efficacy of four chemical decontaminants for inactivating Bacillus anthracis (causative agent for anthrax) spores in soil.

Agrobacterium is a plant pathogen which causes the "crown-gall" disease, a neoplastic growth that results from the transfer of a well-defined DNA segment ("transferred DNA," or "T-DNA") from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications.

The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.

Chronic wounds, by definition, are those that remain in a chronic inflammatory state and therefore fail to follow normal patterns of the healing process. The chronic wounds present a challenge to physicians and patients alike because they are very difficult to heal, inflict a huge cost to society and impair the quality of life for millions of people. There are many factors that contribute to the development of chronic wounds. One of the most clinically significant impediments to wound healing is infections. Bacteria biofilm formation in wounds is the best unifying explanation for the failure of chronic wounds to heal. This book discusses how the formulation of effective and inexpensive products will be useful to resolve infected chronic wounds with biofilm-producing bacteria.

Cyanobacteria, also known as blue-green algae, blue-green bacteria or cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. They are a significant component of the marine nitrogen cycle and an important primary producer in many areas of the ocean, but are also found in habitats other than the marine environment; in particular, cyanobacteria are known to occur in both freshwater and hypersaline inland lakes. They are found in almost every conceivable environment, from oceans to fresh water to bare rock to soil. Cyanobacteria are the only group of organisms that are able to reduce nitrogen and carbon in aerobic conditions, a fact that may be responsible for their evolutionary and ecological success. Certain cyanobacteria also produce cyanotoxins. This new book presents a broad variety of international research on this important organism.

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.
