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.

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.

Beginning with the basics of lactic acid bacteria and stress response, then working into specific fields of research and current developments, Stress Responses of Lactic Acid Bacteria will serve as an essential guidebook to researchers in the field, industry professionals, and advanced students in the area. The exploration of stress responses in lactic acid bacteria began in the early 90s and revealed the differences that exist between LAB and the classical model microorganisms. A considerable amount of work has been performed on the main genera / species of LAB regarding the genes implicated and their actual role and regulation, and the mechanisms of stress resistance have also been elucidated. Recent genome and transcriptome analyses complement the proteome and genetic information available today and shed a new light on the perception of and the responses to stress by lactic acid bacteria.

Food-borne bacterial pathogens encounter a number of stressors during food processing and preservation. More and more pathogens are able to adapt their physiological properties and/or genetic expression to survive these stressors and pose a risk to food safety and public health. This book provides the reader with a comprehensive overview of common food processing-associated stressors (e.g., heat, cold, acid, osmosis, and oxidation) and deals with the molecular basis of the respective bacterial stress response mechanisms (e.g., viable but nonculturable state, biofilm formation, sporulation, and cross-protection response). Additionally, various chapters cover the response mechanisms of foodborne pathogens to emerging nonthermal sterilisation technologies such as ultrasound, high-pressure processing, pulsed electric fields, ultraviolet light, irradiation and phytochemicals. Through this book we also learn about future prospects for the efficient control of stress adaption in foodborne pathogens to ensure maximum consumer safety. This book offers a valuable resource for researchers, graduate students, food process engineers and product developers in the fields of food science and microbiology.

Microorganisms are ubiquitous and can be found in various environments, ranging from extreme habitats like deep-sea hydrothermal vents, arctic glaciers, and outer space to more common environments such as soil, water, and the human gut. These microorganisms are exposed to diverse stressors, including temperature fluctuations, pH changes, toxin exposure, and nutrient deprivation, antimicrobial agents and host immune responses, which can threaten survival. However, many microorganisms have evolved numerous stress tolerance mechanisms that enable them to adapt and thrive in these challenging environments.

The book compiles the latest studies on microorganisms thriving in extreme conditions. Microbes have been found in extremely high and low temperatures, highly acidic to saline conditions, from deserts to the Dead sea, from hot-springs to underwater hydrothermal vents- the diversity is incredible. The various chapters highlight the microbial life and describe the mechanisms of tolerance to these harsh conditions, and show how an understanding of these phenomena can help us exploit the microbes in biotechnology. The theme of the book is highly significant since life in these environments can give vital clues about the origin and evolution of life on earth, as a lot of these conditions simulate the environment present billions of years ago. Additionally, the study of adaptation and survival of organisms in such environments can be important for finding life on other planets. This book shall be useful for students, researchers and course instructors interested in evolution, microbial adaptations and ecology in varied environments.

Oxylipins are an important class of signaling molecules in plants, which play an important role in plant defence and innate immunity. Oxylipins have critical roles in plant growth and plant responses to physical damage caused by herbivores, insects, and pathogenic microbes. Over the last decade, our understanding of oxylipin production, metabolism, and function, particularly jasmonates, has advanced considerably. Jasmonates have provided further mechanistic insights into enzyme function and signalling cascades. Other oxylipins, such as hydroxy fatty acids, have recently been shown to exhibit individual signaling features and crosstalk with other phytohormones. There is scant literature on plant oxylipins and their relevance to our understanding and therefore, understanding oxylipin production, metabolism, and function is pivotal. As a result, researchers, students, professors, and other book readers will have a thorough understanding of plant oxylipin biosynthesis, structure, and function, assisting in the improvement of plant science. Plant oxylipins: metabolism, physiological roles, and profiling techniques address the mechanism, metabolism, and roles of oxylipins in plant resistance to various biotic and abiotic stimuli in detail. This book covers fundamental ideas in oxylipin production, metabolism, structural biochemistry, and signaling pathways. It also discusses cutting-edge methodologies for oxylipin metabolic profiling, with an emphasis on computing applications. This book is an excellent resource for plant scientists, plant biochemists, biotechnologists, botanists, phytochemists, toxicologists, chemical ecologists, taxonomists, and other scholars in those subjects. The book is written by a global team of professionals. Features Presents concrete and extensive information about a basic and applied aspect of plant oxylipins as well as expanded coverage of signaling mechanisms. Highlights the fundamental concepts of the biosynthesis, metabolism, structural biochemistry, and signaling pathway of oxylipins. Details the state-of-the-art methods and techniques in metabolic profiling of oxylipins in plants. Presents insights on computational applications in the evaluation and study of oxylipins in plants.

Bacterial biofilms are colonies of bacterial cells embedded in their self-produced matrix composed of polysaccharides, DNA, and proteins. They protect bacterial cells against antibiotics, antibacterial agents, soaps and detergents, and shear stress. Some of the most common biofilm-associated infections in humans include urinary tract infections, infection of wounds and surgical sites, diabetic foot ulcers, dental caries (tooth decay) and gingivitis (gum inflammation), ventilator-associated infections, sinusitis, microbial keratitis, secondary infection related to Covid-19 and other viral infections, and so on. Bacterial resistance to common antibiotics (e.g., penicillin, gentamycin, erythromycin, ciprofloxacin, etc.) is driving us to a catastrophic failure of our health systems. Strategies to develop novel antibacterial agents and technology must be prioritized to combat and eradicate biofilms and their associated challenges. This book provides a comprehensive overview of biofilms with chapters on bacterial virulence factors, quorum sensing in bacteria, antimicrobial resistance in bacteria, strategies to develop new antibacterial agents, and much more.

Biofilms are multicellular sessile microbial communities embedded in hydrated extracellular polymeric matrices. Their formation is common in microbial life in most environments, whereas those formed on food-processing surfaces are of considerable interest in the context of food hygiene. Biofilm cells express properties that are distinct from planktonic ones, in particular, due to their notorious resistance to antimicrobial agents. Thus, a special feature of biofilms is that once they have developed, they are hard to eradicate, even when careful sanitization procedures are regularly applied. A large amount of ongoing research has investigated how and why surface-attached microbial communities develop such resistance, and several mechanisms can be acknowledged, such as heterogeneous metabolic activity, cell adaptive responses, diffusion limitations, genetic and functional diversification, and microbial interactions. The articles contained in this Special Issue deal with biofilms of some important food-related bacteria (including common pathogens such as Salmonella enterica, Listeria monocytogenes, and Staphylococcus aureus, as well as spoilage-causing spore-forming bacilli), providing novel insights into their resistance mechanisms and implications, together with novel methods (e.g., use of protective biofilms formed by beneficial bacteria, enzymes) that could be used to overcome resistance and thus improve the safety of our food supply and protect public health.
