Download or read book Bacterial Communication in Foods written by Marco Gobbetti and published by Springer Science & Business Media. This book was released on 2012-11-15 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally assumed that microorganisms synthesize, release, detect and respond to small signaling hormone-like molecules. These molecules are used for a process termed “quorum sensing” (QS), a phenomenon that enables bacteria to sense when the minimal number of cells, or “quorum,” is achieved for a concerted response to be initiated. Words such as “language” and “behavior” are frequently used to depict QS in the literature. More simply put, language and cross-talk between bacteria, and between bacteria and animal or plant hosts, determines the behavior (e.g., beneficial or pathogenic effects) of bacteria. Currently, the major concern is to understand and decode this language. Overall, bacterial cross-talk was mainly studied on environmental, plant, and human pathogenic bacteria. Few studies considered food-related lactic acid bacteria. The cross-talk between bacteria influences the behavior and, in turn, the environmental adaptation and phenotypes. Therefore, it is understood that bacterial cross-talk has important applicative repercussions. The language spoken between bacteria populating the same food ecosystem may condition the phenotypic traits of starter lactic acid bacteria and, consequently, their performance. This Brief aims to define the basis of cell-to-cell signalling in food fermentation and will highlight: (i) microbiology, nutritional, chemical and functional aspects; (ii) functional properties due to microbial adaptation to the gastrointestinal tract; (iii) principal phenotypes under control of QS circuitries; (iv) quorum quenching. This Brief will be the first reference on this topic and it will highlight the main results for a more productive industrial application. Draft content 1. Signals of food related Gram-negative and Gram-positive bacteria The chapter will describe the different signaling languages used by Gram-negative bacteria (N-acyl-L-homoserine lactones) and Gram-positive bacteria (based on the synthesis of post-translationally modified peptides) and the universal chemical lexicon, shared by both Gram-positive and -negative bacteria (autoinducer-2 through the activity of the LuxS enzyme). 2. Phenotypes related to quorum sensing The chapter will describe the bacterial phenotypes, such as virulence, biofilm maturation, bacteriocin synthesis, and secondary metabolite production under control of QS circuitries. 3. Cell-to-cell signalling in fermented food: sourdough The chapter will describe the language spoken between bacteria populating the same food ecosystem (sourdough) and will provide an overview of the conditioned phenotypic traits of starter lactic acid bacteria and, consequently, their performance. 4. Cell-to-cell signalling in fermented food: yoghurt The chapter will describe the language spoken between bacteria populating the same food ecosystem (yoghurt) and will provide an overview of the conditioned phenotypic traits of starter lactic acid bacteria and, consequently, their performance. 5. Probiotic message at the intra-, inter-species and inter-kingdom level The chapter will describe the mechanisms that regulate the interaction between microorganism and host, and the capacity of the microorganism to adapt to environment. Particular reference will also be made to: (i) pathogen inhibition and restoration of microbial homeostasis through microbe-microbe interactions; (ii) enhancement of epithelial barrier function; and (iii) modulation of immune responses. 6. New Perspectives of quorum sensing This chapter will provide an overview of the future perspective regarding quorum sensing, showing that bacterial cross-talk may have important applicative repercussions. It will highlight the interference on the language of QS, which is defined as quorum quenching (QQ). Increasing translation of the bacterial cross-talk has shown that in some environmental circumstances, quenching of the language may occur.
Download or read book Lactic Acid Bacteria written by Marcela Albuquerque Cavalcanti de Albuquerque and published by CRC Press. This book was released on 2020-02-19 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lactic acid bacteria (LAB) are a diverse group of bacteria that comprise low GC content Gram-positive cocci or rods that produces lactic acid as the major end product of the fermentation process. Bifidobacterium genera may also be considered as a part of the LAB group for possessing some similar phenotypical characteristics despite the higher GC content. The key feature of LAB metabolism is efficient carbohydrate fermentation. This contributes to the production of several microbial metabolites that result in the improvement of flavor and texture of fermented foods, in addition to its positive impact on the human health when LAB is administered as a probiotic. The book deals with advances made in the functionalities of LAB, such as their effect on vitamin D receptor expression, impact on neurodegenerative pathologies, production of B-vitamins for food bio-enrichment, production of bacteriocins to improve gut microbiota dysbiosis, production of metabolites from polyphenols and their effects on human health, effect on reducing the immunoreaction of food allergens, as biological system using time-temperature to improve food safety, and the use of probiotics in animal feed. The book also reviews the use of LAB and probiotic technologies to develop new functional foods and functional pharmaceuticals.

Download or read book Microbial Interaction in Fermented Beverages written by Marta E. Farías and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In complex microbial ecosystems constituted by a mixture of different species and strains, interactions will occur between individual micro-organisms. The general environment from which raw food products originate and the microbiological quality of the products in its processed state admits yeast growth. Moreover, the types of interaction found in mixed populations of micro-organisms are classified as direct or indirect interactions. Indirect interaction such as competition, commensalism, mutualism, amensalism or antagonism and neutralism; and direct interaction to predation and parasitism could be occurring. This book examines such interactions in fermented foods and beverages, which develop their nutritional and organoleptic qualities as a result of the metabolic activity of a succession of different micro-organisms. Furthermore, it is known that many microbes use extracellular signals to transmit information about population density and environmental conditions. The authors examine the process as microbes continually respond to varying medium conditions, in which quorum-sensing regulation that is modulated by physical factors and nutrients availability affect the interactions produced between micro-organisms.
Download or read book Bio Farms for Nutraceuticals written by Maria Teresa Giardi and published by Springer Science & Business Media. This book was released on 2011-06-26 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Bio-Farms for Nutraceuticals" can be said to have been born of the NUTRA-SNACKS project within the Sixth Framework Programme Priority on Food Quality and Safety. One objective of NUTRA -SNACK S was to improve the nutritional and eating properties of ready-to-eat products and semi-prepared foodstuffs through better monitoring of the quality and safety of raw materials and the development of innovative processes along the production chain. Another main objective of the project was the production of ready-to-eat snacks with high nutraceutic activity. Seven research institutes and three companies in six European countries were involved in this effort. The co-operation resulted in the production of food having a high content of natural metabolites with the following beneficial health effects: anticancer, antilipidemic, anticholesterol, antimicrobial, antibacterial, antifungal, antiviral, antihypertensive, anti-inflamatory and antioxidant activities.

Download or read book Microbial Fermentation for Improved Sensory Properties and Functionality of Sustainable Foods written by Sylvester Holt and published by Frontiers Media SA. This book was released on 2024-03-11 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional foods such as red meat and beer have unique, recognizable and desirable sensory traits. However, public awareness about health and the climate crisis is now driving consumers and governmental organizations to consume less meat and alcohol. These recognizable flavors are either missing in novel foods because the material is different (plant-based) or removed after the fermentation process. Therefore, there is a need for innovation of the flavor, texture and trigeminal sensations to meet the expectations for the expanding consumer groups. Improvements with proteins and microbial fermentation processes are currently in the process of making novel foods a global commercial success. For example, recent progress in plant-based foods has focused on the production of proteins that may lead to umami flavors and precursors that are transformed into savory flavor compounds in the cooking process. New non-conventional yeast species provide a very promising route to bioflavoring of foods and beverages. In addition, the nutritious value of foods can be dramatically improved by introducing new pathways that produce vitamins and micronutrients, for example for vulnerable groups, such as elderly people with a limited diversity of food choice. The functionality of the food may also be increased by the release/synthesis of bioactive compounds with functional potential (antimicrobial, antioxidant, immunomodulatory activities etc.).
Download or read book Indicators for Waterborne Pathogens written by National Research Council and published by National Academies Press. This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Download or read book How Fermented Foods Feed a Healthy Gut Microbiota written by M. Andrea Azcarate-Peril and published by Springer. This book was released on 2020-12-24 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the role of fermented foods on human gut health and offers a unique contribution to this rapidly growing area of study. Fermented foods have been consumed by humans for millennia. This method of food preservation provided early humans with beneficial bacteria that re-populated the gut microbiota upon consumption. However, novel methods of production and conservation of food have led to severed ties between the food that modern humans consume and the gut microbiota. As a consequence, there has been a documented increase in the prevalence of autoimmune diseases and obesity, which has been correlated to decreased diversity of gut microbes, while infectious disorders have decreased in the three past decades. With the intention of providing a thorough overview of the relationship between fermented foods, nutrition, and health, the editors have grouped the chapters into three thematic sections: food and their associated microbes, the oral microbiome, and the gut microbiome. After an introduction dedicated to the environmental microbiome, Part I provides an overview of what is currently known about the microbes associated with different foods, and compares traditional forms of food preparation with current industrial techniques in terms of the potential loss of microbial diversity. The chapters in Part 2 explore the oral microbiota as a microbial gatekeeper and main contributor to the gut microbiota. Part 3 introduces beneficial modulators of the gut microbiome starting with the establishment of a healthy gut microbiota during infancy, and continuing with the role of probiotics and prebiotics in health preservation and the imbalances of the gut microbiota. In the final section the editors offer concluding remarks and provide a view of the future brought by the microbiome research revolution. This study is unique in its emphasis on the convergence of two very relevant fields of research: the field of studies on Lactic Acid Bacteria (LAB) and fermented foods, and microbiome research. The relationship between these fields, as presented by the research in this volume, demonstrates the intimate connection between fermented foods, the oral and gut microbiota, and human health. Although research has been done on the impact of diet on the gut microbiome there are no publications addressing the restorative role of food as microbe provider to the gut microbiota. This novel approach makes the edited volume a key resource for scientific researchers working in this field.
