Biotechnology Of Lactic Acid Bacteria

This title represents a broad review of current research on LAB and their novel applications with contributions from a number of well-known leading scientists. The book encompasses a wide range of topics including both traditional and novel developing fields, and provides unparalleled, comprehensive information on new advances of genomics, proteomics, metabolism and biodiversity of LAB. Chapters contain state-of-the-art discussions of specific LAB applications such as their use as probiotics, live vaccines and starter cultures in old and new fermented products. The safety of these microorganisms and their interactions with diverse ecosystems natural biota are also covered as well as the new applications of well-known (bacteriocins) and novel (vitamins, low-calorie sugars, etc.) metabolites produced by LAB. This book is an essential reference for established researchers and scientists, doctoral and post-doctoral students, university professors and instructors, and food technologists working on food microbiology, physiology and biotechnology of lactic acid bacteria.

Lactic acid bacteria (LAB) have historically been used as starter cultures for the production of fermented foods, especially dairy products. Over recent years, new areas have had a strong impact on LAB studies: the application of omics tools; the study of complex microbial ecosystems, the discovery of new LAB species, and the use of LAB as powerhouses in the food and medical industries. This second edition of Biotechnology of Lactic Acid Bacteria: Novel Applications addresses the major advances in the fields over the last five years. Thoroughly revised and updated, the book includes new chapters. Among them: The current status of LAB systematics; The role of LAB in the human intestinal microbiome and the intestinal tract of animals and its impact on the health and disease state of the host; The involvement of LAB in fruit and vegetable fermentations; The production of nutraceuticals and aroma compounds by LAB; and The formation of biofilms by LAB. This book is an essential reference for established researchers and scientists, clinical and advanced students, university professors and instructors, nutritionists and food technologists working on food microbiology, physiology and biotechnology of lactic acid bacteria.

Lactic Acid Bacteria in Food Biotechnology: Innovations and Functional Aspects describes the latest advancements in LAB applications in the development of functional foods and fermented foods, biotechnological products using LAB, i.e., bio chemicals (organic acids, bacteriocins, etc.), bioactive and functional biomolecules, comparative genomics of probiotic LAB, and genetically modified LAB in food industry. Bridging the gap between LAB-mediated fermented foods and bioactive compounds, vis-a-vis molecular aspects, this book enables the transition from research to application. The book details applications of LAB in fermented/functional foods including cereals, vegetables, fish, meat cheese, other dairy products, and much more. Other sections cover their biochemistry and biotechnology aspects, bio preservation by bio molecules produced by LAB, bioactive metabolites and biosurfactants, including their value in health and wellness and exploring the genomics of LAB from food to health. Finally, the book addresses genetically modified lactic acid bacteria in food and beverages. Identifies biomolecules released by LAB into foods and their health benefits Describes natural biopreservation by LAB, mechanisms, food safety issues and disease prevention Includes LAB as probiotics, modulation of gut microbiota and health aspects Addresses potentially negative aspects of LAB in producing biogenic amines and health impacts Presents the pros and cons of genetically modified LAB in food industry

A prime reference volume for geneticists, food technologists and biotechnologists in the academic and industrial sectors. Fermentations with lactic acid bacteria determine important qualities such as taste, shelf-life, and food values. New methods of food production require fast and reliable manufacture, which has led to a dramatic surge of interest in the genetic, microbiological and biochemical properties of lactic acid bacteria.

In developing countries, traditional fermentation serves many purposes. It can improve the taste of an otherwise bland food, enhance the digestibility of a food that is difficult to assimilate, preserve food from degradation by noxious organisms, and increase nutritional value through the synthesis of essential amino acids and vitamins. Although "fermented food" has a vaguely distasteful ring, bread, wine, cheese, and yogurt are all familiar fermented foods. Less familiar are gari, ogi, idli, ugba, and other relatively unstudied but important foods in some African and Asian countries. This book reports on current research to improve the safety and nutrition of these foods through an elucidation of the microorganisms and mechanisms involved in their production. Also included are recommendations for needed research.

Lactic Acid Bacteria Biodiversity and Taxonomy Lactic Acid Bacteria Biodiversity and Taxonomy Edited by Wilhelm H. Holzapfel and Brian J.B. Wood The lactic acid bacteria (LAB) are a group of related microorganisms that are enormously important in the food and beverage industries. Generally regarded as safe for human consumption (and, in the case of probiotics, positively beneficial to human health), the LAB have been used for centuries, and continue to be used worldwide on an industrial scale, in food fermentation processes, including yoghurt, cheeses, fermented meats and vegetables, where they ferment carbohydrates in the foods, producing lactic acid and creating an environment unsuitable for the survival of food spoilage organisms and pathogens. The shelf life of the product is thereby extended, but of course these foods are also enjoyed around the world for their organoleptic qualities. They are also important to the brewing and winemaking industries, where they are often undesirable intruders but can in specific cases have desirable benefits. The LAB are also used in producing silage and other agricultural animal feeds. Clinically, they can improve the digestive health of young animals, and also have human medical applications. This book provides a much-needed and comprehensive account of the current knowledge of the LAB, covering the taxonomy and relevant biochemistry, physiology and molecular biology of these scientifically and commercially important microorganisms. It is directed to bringing together the current understanding concerning the organisms’ remarkable diversity within a seemingly rather constrained compass. The genera now identified as proper members of the LAB are treated in dedicated chapters, and the species properly recognized as members of each genus are listed with detailed descriptions of their principal characteristics. Each genus and species is described using a standardized format, and the relative importance of each species in food, agricultural and medical applications is assessed. In addition, certain other bacterial groups (such as Bifidobacterium) often associated with the LAB are given in-depth coverage. The book will also contribute to a better understanding and appreciation of the role of LA B in the various ecosystems and ecological niches that they occupy. In summary, this volume gathers together information designed to enable the organisms’ fullest industrial, nutritional and medical applications. Lactic Acid Bacteria: Biodiversity and Taxonomy is an essential reference for research scientists, biochemists and microbiologists working in the food and fermentation industries and in research institutions. Advanced students of food science and technology will also find it an indispensable guide to the subject.

A thorough history. Lactic acid's chemistry has posed problems that required the large-scale preparation of the acid for study; its manufacture is a complicated process involving many subdisciplines of the science of chemistry; its use encompasses many fields of industrial activity and important asp
