Book Description
Microbial Syntrophy-Mediated Eco-enterprising summarizes and reviews possible microbial applications for eco-industrial sustainability. The book emphasizes a wide spectrum of experimental and theoretical contributions from eminent researchers in the field. In 13 chapters, there is a focus on the microbial intrusions for remediating sites by accumulated pesticides, heavy metals, polyaromatic hydrocarbons, and other industrial effluents. Moreover, the potentiality and key mechanisms used by microorganisms for sustainable environmental management and their prospects are also considered in this new release. The term syntrophy for nutritional interdependence is often used in microbiology to describe the symbiotic relationship between bacterial species. Understanding such interactions can be of considerable interest when we come to manipulate microbes to our own benefit, such as by disrupting pathogenic communities with antibiotics or by promoting efficiency in communities that produce energy or break down waste. - Summarizes and reviews possible microbial applications for eco-industrial sustainability - Includes a wide spectrum of experimental and theoretical contributions from eminent researchers in the field - Focuses on microbial intrusions for remediating sites and other industrial effluents

Book Description
A critical factor for bacterial survival in any environment is the ability to sense and respond appropriately to insults that cause stress to the cell, threatening its survival. Most of these stressors first affect the outer surface of the bacterial cell, are sensed in some way, and defense measures are enacted in response. If the bacteria successfully respond to an encountered stress, they survive and multiply. If they are unsuccessful or inefficient in their response, it can result in death. Efficiently responding to factors that induce stress is especially important for bacteria that inhabit environments that are constantly changing, or for those that inhabit more than one biological niche. In addition, bacterial species that associate with humans and other organisms must be able to overcome stresses that are produced by the host immune response in order to colonize and cause disease. The wide variety of stressors encountered by bacteria has resulted in countless strategies that are used by pathogens to overcome these insults, which we continue to identify. Clearly, a better understanding of these stress response mechanisms may be useful for developing new strategies to combat bacteria that cause certain infectious diseases. This Research Topic aims to highlight our increasing understanding of mechanisms by which bacteria sense and respond to stresses encountered in the host or other environments. Examples of stress response mechanisms of interest include, but are not limited to those that respond to antimicrobials, host immune responses, or environmental changes.

Book Description
Discover important lessons learned about whole organism biology via microbial proteomics This text provides an exhaustive analysis and presentation of current research in the field of microbial proteomics, with an emphasis on new developments and applications and future directions in research. The editors and authors show how and why the relative simplicity of microbes has made them attractive targets for extensive experimental manipulation in a quest for both improved disease prevention and treatment and an improved understanding of whole organism functional biology. In particular, the text demonstrates how microbial proteomic analyses can aid in drug discovery, including identification of new targets, novel diagnostic markers, and lead optimization. Each chapter is written by one or more leading experts in the field and carefully edited to ensure a consistent and thorough approach throughout. Methods, technologies, and tools associated with the most promising approaches are stressed. Key topics covered include: Microbial pathogenesis at the proteome level Whole cell modeling Structural proteomics and computational analysis Biomolecular interactions Physiological proteomics Metabolic reconstruction using proteomics data While presenting the practical utility of proteomics data, the text is also clear on the field's current limitations, pointing to areas where further investigation is needed. Offering a state-of-the-art perspective from internationally recognized experts, this text is ideally suited for researchers and students across the gamut of genomic sciences, including biochemistry, microbiology, molecular biology, genetics, biomedical and pharmaceutical sciences, biotechnology, and veterinary science.

Book Description
Microbial responses to acidic and alkaline pH are important in many areas of bacteriology. For example, the mechanisms of resistance to acidic pH are important in the understanding of the passage of human pathogens through the acid of the stomach; and an understanding of microbial degradation of alkaline industrial waste is important for the environment. Bringing together contributions from an international and interdisciplinary group of experts working on the many aspects of bacterial cellular responses to pH, this stimulating volume draws together new and innovative work in this area. It delineates both similarities and differences between mechanisms of tolerance and response, providing readers with an invaluable resource on the subject.

Book Description
Pathogens respond dynamically to their environment. Understanding their behavior is critical for two important reasons: because of emerging evidence of increased pathogen resistance to established sanitation and preservation techniques and because of the increased use of minimal processing technologies, which are potentially more vulnerable to the development of resistance. Understanding Pathogen Behavior: Virulence, Stress Response And Resistance collects and summarizes the wealth of recent research in this area and its implications for microbiologists and QA staff in the food industry.

Book Description
Cellular stress, being considered as any disturbance in cellular physiology, is a fundamental aspect of tissue and body capacity to adapt to the ever changing environment. It also surges as a consequence of tissue injury or invasion of the body by pathogens. Since the immune system was developed to sense and respond to these deleterious processes, it is reasonable to consider that immune cells are capable of sensing and responding to signs of cellular stress. Moreover, cells of the immune system undergo cellular stress during an immune response. This Research Topic presents a series of articles focusing on how cellular stress influences the outcome of immune responses, covering not only how cellular stress can be a fundamental process during immune cell activation and function, but also how cells of the immune system are capable of sensing and being influenced by factors produced by stressed cells.

Book Description
Gamma/delta (γδ) T-cells are a small subset of T-lymphocytes in the peripheral circulation but constitute a major T-cell population at other anatomical localizations such as the epithelial tissues. In contrast to conventional α/β T-cells, the available number of germline genes coding for T-cell receptor (TCR) variable elements of γδ T-cells is very small. Moreover, there is a prefential localization of γδ T-cells expressing given Vgamma and Vdelta genes in certain tissues. In humans, γδ T-cells expressing the Vg9Vd2-encoded TCR account for anywhere between 50 and >95% of peripheral blood γδ T-cells, whereas cells expressing non-Vd2 genes dominate in mucosal tissues. In mice, there is an ordered appearance of γδ T-cell „waves“ during embryonic development, resulting in preferential localization of γδ T-cells expressing distinct VgammaVdelta genes in the skin, the reproductive organs, or gut epithelia. The major function of γδ T-cells resides in local immunosurveillance and immune defense against infection and malignancy. This is supported by the identification of ligands that are selectively recognized by the γδ TCR. As an example, human Vgamma9Vdelta2 T-cells recognize phosphorylated metabolites („phosphoantigens“) that are secreted by many pathogens but can also be overproduced by tumor cells, providing a basis for a role of these γδ T-cells in both anti-infective and anti-tumor immunity. Similarly, the recognition of endothelial protein C receptor by human non-Vdelta2 γδ T-cells has recently been identified to provide a link for the role for such γδ T-cells in immunity against epithelial tumor cells and cytomegalovirus-infected endothelial cells. In addition to „classical“ functions such as cytokine production and cytotoxicity, recent studies suggest that subsets of γδ T-cells can exert additional functions such as regulatory activity and – quite surpisingly – „professional“ antigen-presenting capacity. It is currently not well known how this tremendous extent of functional plasticity is regulated and what is the extent of γδ TCR ligand diversity. Due to their non-MHC-restricted recognition of unusual stress-associated ligands, γδ T-cells have raised great interest as to their potential translational application in cell-based immunotherapy. Topics of this Research Focus include: Molecular insights into the activation and differentiation requirements of γδ T-cells, role of pyrophosphates and butyrophilin molecules for the activation of human γδ T-cells, role of γδ T-cells in tumor immunity and in other infectious and non-infectious diseases, and many others. We are most grateful to all colleagues who agreed to write a manuscript. Thanks to their contributions, this E-book presents an up-to-date overview on many facets of the still exciting γδ T-cells.
