In a sense, propionic acid bacteria are domesticated bacteria. They might have been used for cheese making as early as 9000 years Be. In the last 40 years their pmctical uses have expanded to include vitamin B12 and propionic acid production, bread baking, starters for ensilage and some pharmaceutical prepamtions. New prospects for their future uses are also emerging, based on the useful properties recently discovered. This monograph is the result of many years of investigating propioni bacteria by the faculty, staff and postgraduate students in the Department of Microbiology at the Moscow State University, as well as a number of scientists in other countries. The encouragement and various contributions of my colleagues has made this book possible, which might as well be entitled "My life with propionic acid bacteria", since these bacteria were the subject of our investigations for more than 40 years. I hope that this book will be of interest not only to scientists of biological specialties, but also to those associated with industrial firms and medical institutions. L.l. Vorobjeva IX Acknowledgements Writing a monograph is impossible without the cooperation of many people I am very grateful to all my postgraduate students - thirty of them - who work at present not only in Russia, but also in various other countries, including Canada, Cuba, Egypt, India, Iran and Vietnam. Many thanks are due to my colleagues who shared my scientific interests and enthusiasm in experimental research. Special thanks are to N. Baranova, E. lordan, N.

Microbial Inhabitants Of Humans

This advanced textbook provides a unique overview of the microbial communities (normal indigenous microbiota) inhabiting those regions of the human body that are exposed to the external environment, including the skin, eyes, oral cavity and the respiratory, urinary, reproductive and gastrointestinal tracts. In order to understand why particular organisms are able to colonise an anatomical region and why the resulting microbial community has a particular composition, an ecological approach is essential. Consequently, the key anatomical and physiological characteristics of each body site are described throughout the book. The crucial roles of the indigenous microbiota in protecting against exogenous pathogens, regulating the development of our immune system and mucosae, and providing nutrients are also discussed. The involvement of these organisms in infections of healthy and debilitated individuals are discussed throughout and methods of manipulating the composition of the indigenous microbiota for the benefit of human health are also described.

The Human Microbiota And Chronic Disease

Microbiota-associated pathology can be a direct result of changes in general bacterial composition, such as might be found in periodontitis and bacterial vaginosis, and/or as the result of colonization and/or overgrowth of so called keystone species. The disruption in the composition of the normal human microbiota, or dysbiosis, plays an integral role in human health and human disease. The Human Microbiota and Human Chronic Disease: Dysbioses as a Cause of Human Pathology discusses the role of the microbiota in maintaining human health. The text introduces the reader to the biology of microbial dysbiosis and its potential role in both bacterial disease and in idiopathic chronic disease states. Divided into five sections, the text delineates the concept of the human bacterial microbiota with particular attention being paid to the microbiotae of the gut, oral cavity and skin. A key methodology for exploring the microbiota, metagenomics, is also described. The book then shows the reader the cellular, molecular and genetic complexities of the bacterial microbiota, its myriad connections with the host and how these can maintain tissue homeostasis. Chapters then consider the role of dysbioses in human disease states, dealing with two of the commonest bacterial diseases of humanity – periodontitis and bacterial vaginosis. The composition of some, if not all microbiotas can be controlled by the diet and this is also dealt with in this section. The discussion moves on to the major ‘idiopathic’ diseases afflicting humans, and the potential role that dysbiosis could play in their induction and chronicity. The book then concludes with the therapeutic potential of manipulating the microbiota, introducing the concepts of probiotics, prebiotics and the administration of healthy human faeces (faecal microbiota transplantation), and then hypothesizes as to the future of medical treatment viewed from a microbiota-centric position. Provides an introduction to dysbiosis, or a disruption in the composition of the normal human microbiota Explains how microbiota-associated pathology and other chronic diseases can result from changes in general bacterial composition Explores the relationship humans have with their microbiota, and its significance in human health and disease Covers host genetic variants and their role in the composition of human microbial biofilms, integral to the relationship between human health and human disease Authored and edited by leaders in the field, The Human Microbiota and Human Chronic Disease will be an invaluable resource for clinicians, pathologists, immunologists, cell and molecular biologists, biochemists, and system biologists studying cellular and molecular bases of human diseases.

Bacteriocins Of Lactic Acid Bacteria

Bacteriocins of Lactic Acid Bacteria is based on the 1990 Annual Meeting of the Institute of Food Technologists held in Dallas, Texas. It describes a number of well-characterized bacteriocins and, where possible, discusses practical applications for those that have been defined thus far from the lactic acid bacteria. The book begins with an introductory overview of naturally occurring antibacterial compounds. This is followed by discussions of methods of detecting bacteriocins and biochemical procedures for extraction and purification; genetics and cellular regulation of bacteriocins; bacteriocins based on the genera of lactic acid bacteria Lactococcus, Lactobacillus, Pediococcus, and Leuconostoc, and related bacteria such as Carnobacterium and Propionibacterium; and the regulatory and political aspects for commercial use of these substances. The final chapter sets out the prognosis for the future of this dynamic area. The information contained in this book should benefit those with interest in the potential for industrial use of bacteriocins as preservative ingredients. Anyone interested in lactic acid bacteria or the biosynthesis, regulation, and mechanisms of inhibition of these proteinaceous compounds will also appreciate the material presented. These include food scientists, microbiologists, food processors and product physiologists, food toxicologists, and food and personal product regulators.

This book underlines the importance of reciprocal interactions between probiotics and humans in terms of stress induction, epigenetic control of cellular responses, oxidative status, bioactive molecules biosynthesis, moonlighting proteins secretion, endogenous toxins neutralization, and several other biological functions. It explores how these responses can affect metabolism and metabolic-related disorders, gutbrain axis balance, mood, inflammatory, allergic and anti-infective reactions, cancer, and ageing. The book explores how probiotics create a dynamic and "fluid" network of signals able to control the balance between healthy and altered human status.

This book is appropriate for advanced undergraduate students of micro biology and biological sciences in universities and colleges, as well as for research workers entering the field and requiring a broad contemporary view of anaerobic bacteria and associated concepts. Obligate anaerobes, together with microaerophils, are characterized by their sensitivity to oxygen. This dictates specialized laboratory methods a fact which has led to many students being less familiar with anaerobes than their distribution and importance would warrant The metabolic strategies such as methanogenesis, an oxygenic photosynthesis and diverse fermenta tive pathways which do not have equivalents in aerobic bacteria also make anaerobes worthy of attention. In these limited pages an attempt has been made to cover the varied aspects of anaerobic bacteria, and a bibliography has been included, which will allow individual topics to be pursued in greater detail. We are grateful to Mrs Winifred Webster and Mrs Hilary Holdsworth for typing the manuscript and to the Leeds University Audio Visual Service for preparing the figures. Finally, our thanks go to the students, postgradu ates and wives who read and criticized the manuscript.
