Book Description
The world is full of plants and animals that have their own defenses, producing various substances in their daily fight against bacteria, fungi, or other agents. These products are alternatives to conventional antimicrobials that have a poor reputation with consumers. Many of these compounds are well known; however, the multiple types of structures together with the variable responses depending of the type of biocontrol needed in a wide range of applications, such as clinical, agricultural, general hygiene, and food, necessitates the continuous search for specific applications and the continuous study of how to use these substances. The present book provides a summary of reviews and original research works that explore the multiple alternatives for the use of these compounds.

Book Description
It is estimated that foodborne microorganisms in the United States cause 48 million sicknesses, 128,000 hospitalizations and 3,000 deaths each year. Food spoilage due to decay-causing microorganisms is also an issue in both developing and developed countries with 30-40% annual loss of fruits and vegetables. Synthesized antimicrobials (preservatives) are commonly used by the food industry to enhance microbial safety and increase shelf-life. However, food and agricultural industries are experiencing a lack of potent antimicrobial agents to secure the safety and maintain the quality of food products. Some synthetic preservatives may produce harmful by-products and damage the environment. There is also increasing incidence of antibiotics-resistant pathogens which has drawn great concern from the scientific communities and public health professionals. Therefore, there is increasing interest in the use of natural antimicrobials to enhance microbial safety, reduce spoilage and extend the shelf life of food. Natural antimicrobials are from plants, microorganisms and animals. They cover a wide variety of compounds including phenolics, terpenes, bacteriocins, peptides, proteins, natural polymers, fatty acids (lipids), and organic acids. Overall reviews of well-known natural or bio-based antimicrobials are first presented. The book then discusses antimicrobials of plant sources and their applications in foods and animal health. A number of chapters address the combinations of natural antimicrobials with non-thermal processing technologies to achieve additive and synergistic effects. The use of natural antimicrobials in packaging and coating, as well as both well-studied and novel biobased antimicrobials are discussed. Furthermore, the needs for toxicological evaluations of natural and bio-based antimicrobials are presented and protocols are recommended. Moreover, there is discussion in many of the chapters on the modes of action, mechanisms, and industrial aspects of applying natural or bio-based antimicrobials.

Book Description
Nanostructures for Antimicrobial Therapy discusses the pros and cons of the use of nanostructured materials in the prevention and eradication of infections, highlighting the efficient microbicidal effect of nanoparticles against antibiotic-resistant pathogens and biofilms. Conventional antibiotics are becoming ineffective towards microorganisms due to their widespread and often inappropriate use. As a result, the development of antibiotic resistance in microorganisms is increasingly being reported. New approaches are needed to confront the rising issues related to infectious diseases. The merging of biomaterials, such as chitosan, carrageenan, gelatin, poly (lactic-co-glycolic acid) with nanotechnology provides a promising platform for antimicrobial therapy as it provides a controlled way to target cells and induce the desired response without the adverse effects common to many traditional treatments. Nanoparticles represent one of the most promising therapeutic treatments to the problem caused by infectious micro-organisms resistant to traditional therapies. This volume discusses this promise in detail, and also discusses what challenges the greater use of nanoparticles might pose to medical professionals. The unique physiochemical properties of nanoparticles, combined with their growth inhibitory capacity against microbes has led to the upsurge in the research on nanoparticles as antimicrobials. The importance of bactericidal nanobiomaterials study will likely increase as development of resistant strains of bacteria against most potent antibiotics continues. Shows how nanoantibiotics can be used to more effectively treat disease Discusses the advantages and issues of a variety of different nanoantibiotics, enabling medics to select which best meets their needs Provides a cogent summary of recent developments in this field, allowing readers to quickly familiarize themselves with this topic area

Book Description
Materials and equipment in food processing industries are colonized by surface-associated microbial communities called biofilms. In these biostructures microorganisms are embedded in a complex organic matrix composed essentially of polysaccharides, nucleic acids and proteins. This organic shield contributes to the mechanical biofilm cohesion and triggers tolerance to environmental stresses such as dehydratation or nutrient deprivation. Notably, cells within a biofilm are more tolerant to sanitation processes and the action of antimicrobial agents than their free living (or planktonic) counterparts. Such properties make conventional cleaning and disinfection protocols normally not effective in eradicating these biocontaminants. Biofilms are thus a continuous source of persistent microorganisms, including spoilage and pathogenic microorganisms, leading to repeated contamination of processed food with important economic and safety impact. Alternatively, in some particular settings, biofilm formation by resident or technological microorganisms can be desirable, due to possible enhancement of food fermentations or as a means of bioprotection against the settlement of pathogenic microorganisms. In the last decades substantial research efforts have been devoted to unravelling mechanisms of biofilm formation, deciphering biofilm architecture and understanding microbial interactions within those ecosystems. However, biofilms present a high level of complexity and many aspects remain yet to be fully understood. A lot of attention has been also paid to the development of novel strategies for preventing or controlling biofilm formation in industrial settings. Further research needs to be focused on the identification of new biocides effective against biofilm-associated microorganisms, the development of control strategies based on the inhibition of cell-to-cell communication, and the potential use of bacteriocins, bacteriocin-producing bacteria, phage, and natural antimicrobials as anti-biofilm agents, among others. This Research Topic aims to provide an avenue for dissemination of recent advances within the “biofilms” field, from novel knowledge on mechanisms of biofilm formation and biofilm architecture to novel strategies for biofilm control in food industrial settings.
