Book excerpt: Welcome to the wonderful world of microbiology! Yay! So. What is microbiology? If we break the word down it translates to "the study of small life," where the small life refers to microorganisms or microbes. But who are the microbes? And how small are they? Generally microbes can be divided in to two categories: the cellular microbes (or organisms) and the acellular microbes (or agents). In the cellular camp we have the bacteria, the archaea, the fungi, and the protists (a bit of a grab bag composed of algae, protozoa, slime molds, and water molds). Cellular microbes can be either unicellular, where one cell is the entire organism, or multicellular, where hundreds, thousands or even billions of cells can make up the entire organism. In the acellular camp we have the viruses and other infectious agents, such as prions and viroids. In this textbook the focus will be on the bacteria and archaea (traditionally known as the "prokaryotes,") and the viruses and other acellular agents.

Download or read book Nutrition Microbiota and Noncommunicable Diseases written by Julio Plaza-Díaz and published by MDPI. This book was released on 2021-01-20 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Health is defined as “the state of the organism when it functions optimally without evidence of disease”. Surprisingly, the words “microbes” or “microorganism” are missing in this definition. The regulation of gut microbiota is mediated by an enormous quantity of aspects, such as microbiological factors, host characteristics, diet patterns, and environmental variables. Some protective, structural, and metabolic functions have been reported for gut microbiota, and these functions are related to the regulation of homeostasis and host health. Host defense against pathogens is, in part, mediated through gut microbiota action and requires intimate interpretation of the current microenvironment and discrimination between commensal and occasional bacteria. The present Special Issue provides a summary of the progress on the topic of intestinal microbiota and its important role in human health in different populations. This Special Issue will be of great interest from a clinical and public health perspective. Nevertheless, more studies with more samples and comparable methods are necessary to understand the actual function of intestinal microbiota in disease development and health maintenance.
Download or read book Colonic Microbiota Nutrition and Health written by G.R. Gibson and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1 2 MARCEL B. ROBERFROID AND GLENN R. GIBSON 1 Universite Catholique de Louvain, Department of Pharmaceutical Sciences, Avenue Mounier 73, B-1200 Brussels, BELGIUM 2 Food Microbial Sciences Unit, Department of Food Science and Technology, The University of Reading, Reading, UK It is clear that diet fulfils a number of important human requirements. These include the provision of sufficient nutrients to meet the requirements of essential metabolic pathways, as well as the sensory (and social) values associated with eating. It is also evident that diet may control and modulate various body functions in a manner that can reduce the risk of certain diseases. This very broad view of nutrition has led to the development of foodstuffs with added "functionality". Many different definitions of functional foods have arisen. Most of these complicate the simple issue that a functional food is merely a dietary ingredient(s) that can have positive properties above its normal nutritional value. Other terms used to describe such foods include vitafoods, nutraceuticals, pharmafoods, foods for specified health use, health foods, designer foods, etc. Despite some trepidation, the concept has recently attracted much interest through a vast number of articles in both the popular and scientific media.

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 Gut Flora Nutrition Immunity and Health written by Roy Fuller and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some foods, as well as contributing essential nutrients to the body, also contain additional components that improve disease resistance and general health status over and above that induced by ingestion of conventional foods. The so-called functional foods, and prebiotics and probiotics exemplify the relationship that exists between nutrition, the gut (the largest element of the body’s immune system) and its flora, immunology and health. This important book contains chapters covering the basic principles of nutrition, gut microecology and immunology, as well as chapters which discuss the way in which this knowledge may be used to explain the positive and negative effects of food consumption, metabolism, probiotics and prebiotics. Food hypersensitivity and allergic reactions, carcinogenesis, and the role of nutrition in the reduced immunity of the aged are also discussed in detail. The editors of this exciting and informative book, who between them have a vast wealth of knowledge of the area, have drawn together and carefully edited international contributions from many well known and respected workers in the area. Gut Flora, Nutrition, Immunity and Health provides essential information for a range of professionals including nutritionists, dietitians, food scientists, microbiologists, gastroenterologists, immunologists and all personnel working in the development and use of functional foods and supplements, prebiotics and probiotics. Libraries in universities and research establishments where these subjects are studied and taught, and pharmaceutical and food companies should have multiple copies of this very useful book on their shelves. Roy Fuller is a consultant in gut microecology, based in Reading, UK; Gabriela Perdigón is based at the Centro de Referencia para Lactobacillus (CERELA) and at the Faculty of Biochemistry, Chemistry and Pharmacy of Tucuman University, Argentina.
Download or read book Bacterial Metabolism written by G. Gottschalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been written for students who are taking a course in bacterial metabolism. I hope, however, that scholars will also find it useful either as a help in teaching bacterial metabolism or as a review on the special aspects of metabolism in bacteria. The concept of this book results from my experience in teaching bacterial metabolism. In the first chapters the principal reactions of the energy and biosynthetic metabolism have been discussed using Escherichia coli as a model organism. Then the diversity of aerobic metabolism has been out lined. Following a brief description of the regulation of the level and the activity of enzymes in bacteria the characteristic features of fermentative, chemolithotrophic and phototrophic metabolism have been discussed. Finally, the last chapter has been devoted to nitrogen fixation. Throughout the text I have tried not only to describe metabolic pathways and enzyme reactions but also to elucidate the physiology of the microorganisms which carry out all these metabolic reactions. Two comments regarding the formulas used in this book are necessary.
