Beginning with the basics of lactic acid bacteria and stress response, then working into specific fields of research and current developments, Stress Responses of Lactic Acid Bacteria will serve as an essential guidebook to researchers in the field, industry professionals, and advanced students in the area.
The exploration of stress responses in lactic acid bacteria began in the early 90s and revealed the differences that exist between LAB and the classical model microorganisms. A considerable amount of work has been performed on the main genera / species of LAB regarding the genes implicated and their actual role and regulation, and the mechanisms of stress resistance have also been elucidated. Recent genome and transcriptome analyses complement the proteome and genetic information available today and shed a new light on the perception of and the responses to stress by lactic acid bacteria.
Editorial Reviews
Review
From the reviews:
“The book is a 530-page practical and timely resource on this microbiological topic associated with food technology, and food safety issues and problems. The focus is on current knowledge of the stress physiology of LAB. … All in all, I enjoyed reading this comprehensive book on stress responses of LAB. A must-have for everyone in food technology and probiotics research.” (K. Venema, Beneficial Microbes, Vol. 3 (2), June, 2012)
From the Back Cover
Lactic acid bacteria (LAB) constitute a heterogeneous group of bacteria that are renowned for the crucial role they play in the health of humans and animals. While some LAB are food-related and probiotic, remaining harmless and at times even conferring health benefits to the consumer, others are host-associated and include some of the most severe human and veterinary pathogens.
Due to their economic importance for the food industry and their health-related implications as probiotics or pathogens, the genetics, physiology and metabolism of LAB have been under rigorous investigation over the past decades. During food processing and storage, LAB reside under adverse environmental conditions designed to be bacteriostatic or bactericidal for food spoilage microorganisms and foodborne pathogens. In addition, during consumption, the key feature of probiotic strains is their aptitude to survive through the harsh environment of the gastrointestinal tract of the host so as to reach and colonize the intestine and exert their health-promoting effects. Furthermore, the pathogenic nature of certain LAB species has been clearly associated with their tolerance to environmental stresses.
Organized into 5 parts, this book discusses the current knowledge of the stress physiology of LAB. Part I provides an introductory overview of the stress responses of LAB; Part II focuses on the responses of LAB towards specific environmental stresses; Part III presents the stress responses of LAB in the context of species and genera; Part IV discusses the applications and the future aspects of LAB stress research; and Part V highlights in a concluding summary the most important research challenges in the field that will significantly improve our conception of stress behavior in LAB.
