Bacteriocins are a heterogeneous group of peptides or proteins with antimicrobial activity synthesised ribosomally and released extracellularly by bacteria belonging to nearly all taxonomic groups. These are classified according to their genetic, structural and biochemical characteristics. Use of bacteriocinogenic cultures to improve the safety of food products would represent an attractive alternative to the use of chemical preservatives, based on the long history of safe use of naturally occurring bacteriocin producing food-grade bacteria. Chapter One in this book discusses the effects of bacteriocin production in situ by bacteria in food products and evidence for the probiotic properties of bacteriocin producers are collected in order to identify processes in which the application of bacteriocinogenic cultures can be effectively implemented. Chapter Two examines the importance of the use of bacteriocins in food preservation and also their potential use in human health. Chapter Three discusses a broad range of bacteriocin applications focusing not only on food biopreservation but also on biofilm control. Chapter Four reviews the recent applications of bacteriocin-producing PC in meats and meat products throughout the world. Chapter Five evaluates the effect of mild pressure treatments in the survival of Pediococcus acidilactici HA-6111-2 and on its bacteriocin production capacity.

A comprehensive manual of phytobacteriology, this work is heavily illustrated with over 200 colour photographs and line illustrations. It begins by outlining the history and science of bacteriology and gives an overview of the diversity and versatility of complex bacteria. It then explains the characterization, identification and naming of complex bacteria, and explores how bacteria can cause disease and how plants react to such disease. The book also discusses the economic importance of bacterial diseases as well as strategies for their control and the reduction of crop losses. It concludes with 50 examples of plant pathogenic bacteria and the diseases that they cause.

This book provides readers with the latest developments in Listeria Monocytogenes research. Topics covered include its growth in biofilms in the food industry; molecular mechanisms involved in the food-related subsistence of Listeria Monocytogenes; an epidemiological update and the control possibilities for outbreaks of L. Monocytogenes; how to control L. Monocytogenes biofilms on food contact surfaces; methods for killing activities of macrophages against L. Monocytogenes infection; and a review of some of the most exciting developments in the analysis of the interaction between L. Monocytogenes and the host GI tract.

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 ability of various microorganisms to attach to surfaces and create biofilms on them is rather a cause of concern for many industries, including for those occupied with food production and processing. Thus, the attachment of bacterial pathogens to food processing equipment is considered as an essential contributing factor in foodborne disease outbreaks, since this may ultimately lead to the contamination of food products. Improperly cleaned surfaces promote soil build-up, and, in the presence of water, contribute to the development of microbial biofilms which may contain pathogenic bacteria, such as Salmonella. Salmonella enterica is one of the most significant enteric foodborne bacterial pathogens, with host-adapted strains able to cause systemic human infections and persist for long periods of time, posing significant public health problems. This book discusses the prevalence, risk factors and treatment options of Salmonella.

Enterococcus faecalis is a gram-positive, coccus shaped, lactic acid bacterium, with demonstrated ubiquity across multiple anatomical sites. Enterococcus faecalis isolates have been isolated from clinical samples as the etiological agent in patients with overt infections, and from body sites previously thought to be sterile but absent of signs and symptoms of infection. E. faecalis is implicated in both human health and disease, recognised as a commensal, a probiotic and an opportunistic multiply resistant pathogen. E faecalis has emerged as a key pathogen in nosocomial infections. Enterococcus faecalis is a commensal bacterium inhabiting the gastro-intestinal tract of humans. Interestingly, although it is not clear whether E faecalis is part of the oral cavity microbiome, it is frequently recovered from root canal infections. Specifically, it is the major pathogen found in persistent infections associated with root canal treatment failure. Moreover, E faecalis is one of the leading multidrug resistant nosocomial pathogens, causing infective endocarditis, and participating in urinary tract, wound, and device- device-related infections. This book discusses the molecular characteristics, its role in nonsocomial infections and the antibacterial effects of Enterococcus faecalis. It begins by discussing the virulence factors of enterococcus faecalis and concludes with E faecalis in dental infections.

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.

Listeria monocytogenes has emerged as one of the major food-borne pathogens, characterised by high hospitalisation and case fatality rates in humans. In this book the authors present current research in the study of this foodborne pathogen. Topics discussed include the natural approaches for controlling L. monocytogenes; L. monocytogenes in ready-to-eat foods and intervention strategies; carbohydrate utilisation by L. monocytogenes and its influence on virulence gene expression; ozone and atmospheric cold plasma for control of L. monocytogenes; the potential of visible light as a means of controlling L. monocytogenes in the food chain; spatial distribution of L. monocytogenes and pseudomonas fluorescens in mixed biofilms; the main hygienic aspects of the processing and marketing of L. monocytogenes and Salmosalar; detection of L. monocytogenes and Listeria spp. in food and feed products; prevalence and control of L. monocytogenes in food processing environments; antimicrobial resistance, and growth kinetics of L. monocytogenes in ready-to-eat foods; novel technologies for controlling L. monocytogenes in ready-to-eat foods; the effect of soil abiotic and biotic factors on the preservation and reproduction of L. monocytogenes; the structure and function of the pathogen; and the prevalence of L. monocytogenes and occurrence of Listeriosis from ready-to-eat fresh fruits and vegetables.

Molecular Biology has proved to be one of the more fruitful technological approaches to science, being both very powerful and able to generate valuable intellectual property. This book aims to present examples in the application of molecular biology and genetic engineering in bacteriology. The book discusses the diverse roles of bacteria in ecosystems and it gives significant contributions from biotechnology approaches.

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.

This important book discusses the ethical code regarding possible introduction of exogenous bacterial species into the environment, as well as various other applications of bacteria in environmental biotechnology.

While we have a feeling that our 'thought experiment' could bear fruit, we are far from the idea that equivalent expressions by the brain and the immune function point to an axis of both systems. Al-though major players, they also depend on the regulation of the rest of the body. As we focus here rather on a social context, many more factors are to be accounted for. Shanty-towns, rather than being seen in a dismissive context, may provide clues to historical conditions, a tip off perhaps to update the idea of 'individualistic' immunity. Subjected to all kinds of inward and outward interferences, obviously, a historical approach is complex. Urban overcrowding, by replacing nomadic life, allowed multiple interacting brains to develop civilization and science. The fact that survival under prolonged siege had been recorded, filthy food and water supply notwithstanding, suggests that collective immune adaptation may not be out of question either. Fortunately, experimental evidence in mice and other animal comes in support to our hypothesis of collective immunity. As yet no consensus about immune stimulation or downplaying has been reached, our aim being the possibility of reciprocal immune influence as such.

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.

Pathological bacteria are only 5% of the bacterial population. The other 95% promote the health and well-being of Earth. The digestive tract holds trillions of archaebacteria from over 4 1/2 billion years ago. When in danger, bacteria create shells for protection. Are humans evolved shells in order to protect the bacteria from atmospheric oxygen? Life forms are descended from prokaryote archaebacteria, for whom oxygen is unnecessary. After millions of years of evolution, can bacteria now direct humans to return the planet, through pollution, ozone depletion, or a nuclear disaster, to a more manageable level of oxygen from a present 21% to less than 1%? No bacteria reside in the cranial brain. Was the enteric nervous system the first brain? Are the archaebacteria within the gastrointestinal tract directing the actions of the body? Are the archaebacteria the architects and directors of evolution?

"Although most people are aware that bacteria are all around us, few would guess that they produce such distinctive and accessible signs. Whether you're walking on the beach, visiting a zoo or aquarium, buying groceries, looking for fossils, drinking beer, traipsing through a swamp, or cleaning scum from beneath a dripping outdoor faucet, you're surrounded by bacterial field marks. You don't need a laboratory or fancy equipment to find out what kind of bacteria are there—this guide will tell you how."—from the Introduction Bacteria are an integral aspect of every habitat in which they occur and affect the lives of humans, other animals, and plants in many ways. Too often, we equate "bacterium" with "pathogen" and think of bacteria as things to avoid. In a fascinating guide perfect for naturalists, students, teachers, and tourists alike, Betsey Dexter Dyer lets the reader know that it is possible to observe bacteria with all the senses. Many groups of bacteria can be easily identified in the field (or in the refrigerator) without a microscope. Written for curious souls of all ages, A Field Guide to Bacteria opens our eyes—and noses and ears—to this hidden (or neglected) world around us. Useful illustrations, including 120 color photographs, accompany Dyer's lively text throughout.

The Archaea, or archaebacteria, constitute the fifth kingdom of living organisms, as distinct from true bacteria as from fungi, animals, and plants. They were very likely the first life forms, from which all other living things evolved, because they are naturally adapted to thrive in the anoxic extreme environments that prevailed when life originated on the earth. Less than 20 years ago they were discovered inhabiting hot springs, salt pans, animal rumens, deep sea vents, soils, and deeply buried sediments in environments in which other life forms could not survive. Their discovery has given a unique vantage on the principles of life, because they present unique life histories and metabolisms, in effect a novel, previously unrecognized type of life. Many of the Archaea are of significant commercial importance; for instance, PCR, which has revolutionized molecular biology, is based on enzymes found in a member of the Archaea that was originally found in a hot geyser pool in Yellowstone National Park.

Designed as an upper-level textbook and a reference for researchers, this important book concentrates on central concepts of the bacterial lifestyle. Taking a refreshingly new approach, it present an integrated view of the prokaryotic cell as an organism and as a member of an interacting population.

BACTERIAL ADHESION Molecular and Ecological Diversity Edited by Madilyn Fletcher

Over the last twenty years, research has revealed the enormous complexity underlying the phenomenon of bacterial adhesion. The initial research goal was to understand the mechanism of attachment and its effects on the bacteria as well as the host. As research progressed, however, it became evident that many different attachment mechanisms exist. These diverse forms of adhesion are the results of numerous evolutionary pressures, and each may be part of a larger behavioral strategy.

This comprehensive overview details how diversity in habitat and ecological requirements has led to enormous variety in adhesive cell components, underlying genetic determinants, and behavioral strategies. It presents the latest research on adhesion mechanisms and strategies found in diverse environments and microorganisms, including the new environment of biomaterials.

Bacterial Adhesion: Molecular and Ecological Diversity examines adhesion as a strategy for nutrient access and as a phase in the complex behavior of life cycle processes. It covers the latest research and innovative approaches in the field, including:

• Conceptual advances in research on the adhesion of bacteria to oral surfaces
• Enhancing colonization in a fluctuating environment
• The cellulosome: a cell-surface organelle for the adhesion to and degradation of cellulose
• Pseudomonas aeruginosa—versatile attachment mechanisms
• Sensing, response, and adaptation to surfaces
• Myxococcus coadhesion and role in the life cycle

Edited by a leading authority on bacterial adhesion and featuring contributions from the field's leading experts, this book speaks to researchers in all areas of microbiology, biotechnology, environmental technology, and environmental science, as well as urology, immunology, and infectious diseases.
