The Microbiological Quality of Food: Foodborne Spoilers covers the microbiological spoilage of foods, with a focus on the spoilers, the foods themselves, and the signs of spoilage. The book addresses traditional spoilers (filamentous fungi, spore-forming bacteria, yeasts, SSO in fish), as well as some emerging spoilers (Pseudomonas), now recognized as primary targets. Sections also provide a brief overview of important foods (vegetables, milk and dairy products, meat, and fish) and addresses safety and economic loss. Details on the signs of spoilage, how to prevent spoilers, and methods of detecting spoilage and spoilage microorganisms in foods are also presented. This is an authoritative reference for researchers, scientists and students who need to understand microbial spoilage, the impact of biofilm on the quality and safety of many foods, and the implications of biofilm for spoilage and shelf life. Hot topics covered by this book include the possible link between food spoilage and food safety as a consequence of antibiotic resistance spreading all over the world. - Presents Definitions: taxonomy, definition of food spoilage according to the literature and regulatory frameworks - Provides Case Studies: for some foods and emerging spoilers, along with examples of how to prolong the shelf life - Includes Calculations/worked examples: models and practical examples to calculate the shelf life of foods and to design and effective method to inhibit spoilers

This comprehensive book describes in detail the most topical emerging areas of scientific importance involving the use of spores and covers their use as probiotics in humans and animals and also with plants. In addition authors present the emerging use of the spore as a tool for nanobiotechnology where the spore can be used for the efficient display of heterologous proteins on the spore surface. The use of this technology and systematics of spore forming bacteria, and the architecture and assembly of spores. The innovative topics covered in this book will be of particular interest to scientists working in all areas of probiotic research and vaccine technology and is recommended reading for microbiologists involved with Bacillus spp. and other spore forming bacteria.

The study of bacterial spores spans biosecurity to ecology The first articles describing the sporulation process were published by Robert Koch and Ferdinand Cohn in the late 19th century. Although most of the work accomplished in the past 50 years has focused on the model organism Bacillus subtilis, more recent work significantly expanded the scope of sporulation research to integrate medically relevant spore pathogens, such as B. anthracis and Clostridium difficile, as well as investigations of the ecology of spore-forming species. This new direction is supported by an explosion of novel techniques that can also be applied to nonmodel organisms, such as next-generation sequencing, metagenomics, and transcriptomics. The Bacterial Spore provides a comprehensive series of reviews of the major topics in spore biology that represent intensive, cutting-edge spore research. Editors Adam Driks and Patrick Eichenberger assembled chapters written by a team of diverse and multidisciplinary experts in biodefense and microbial forensics to produce an overview of topics of spore research, such as spore molecular biology, bioremediation, systems biology, issues in biodefense, and the challenge of food safety that is accessible to any reader, regardless of expertise. The Bacterial Spore also encompasses the diversity of spore research, which will appeal to those seeking to broaden their knowledge. The Bacterial Spore is a reference for a wide range of readers, including geneticists, cell biologists, physiologists, structural and evolutionary biologists, applied scientists, advanced undergraduate and graduate students, and nonresearchers, such as national security professionals.

An authoritative guide to microbiological solutions to common challenges encountered in the industrial processing of milk and the production of milk products Microbiology in Dairy Processing offers a comprehensive introduction to the most current knowledge and research in dairy technologies and lactic acid bacteria (LAB) and dairy associated species in the fermentation of dairy products. The text deals with the industrial processing of milk, the problems solved in the industry, and those still affecting the processes. The authors explore culture methods and species selective growth media, to grow, separate, and characterize LAB and dairy associated species, molecular methods for species identification and strains characterization, Next Generation Sequencing for genome characterization, comparative genomics, phenotyping, and current applications in dairy and non-dairy productions. In addition, Microbiology in Dairy Processing covers the Lactic Acid Bacteria and dairy associated species (the beneficial microorganisms used in food fermentation processes): culture methods, phenotyping, and proven applications in dairy and non-dairy productions. The text also reviews the potential future exploitation of the culture of novel strains with useful traits such as probiotics, fermentation of sugars, metabolites produced, bacteriocins. This important resource: Offers solutions both established and novel to the numerous challenges commonly encountered in the industrial processing of milk and the production of milk products Takes a highly practical approach, tackling the problems faced in the workplace by dairy technologists Covers the whole chain of dairy processing from milk collection and storage though processing and the production of various cheese types Written for laboratory technicians and researchers, students learning the protocols for LAB isolation and characterisation, Microbiology in Dairy Processing is the authoritative reference for professionals and students.

Aerobic endospore-forming bacteria are found in soils of all kinds, ranging from acid to alkaline, hot to cold, and fertile to desert. It is well known that endospores confer special properties upon their owners and play dominant parts in their life cycles and dispersal, and much has been written about the spores, genetics, and economic importance of these organisms. Much has also been written about soil ecology, but there is a relative dearth of literature that brings together different aspects of the behaviour and characters of endospore-formers with their contributions to soil ecosystems. This Soil Biology volume fills that gap. Following chapters that describe the current classification of these organisms, that review methods for their detection and for studying their life cycles in soils, and that examine their dispersal, other chapters show that they are active and dynamic members of soil floras that interact widely with other soil inhabitants, with roles in nitrogen fixation, denitrification, and soil remediation.

The data in this book are new or updated, and will serve also as Origin of Life and evolutionary studies. Endospores of bacteria have a long history of use as model organisms in astrobiology, including survival in extreme environments and interplanetary transfer of life. Numerous other bacteria as well as archaea, lichens, fungi, algae and tiny animals (tardigrades, or water bears) are now being investigated for their tolerance to extreme conditions in simulated or real space environments. Experimental results from exposure studies on the International Space Station and space probes for up to 1.5 years are presented and discussed. Suggestions for extaterrestrial energy sources are also indicated. Audience Researchers and graduate students in microbiology, biochemistry, molecular biology and astrobiology, as well as anyone interested in the search for extraterrestrial life and its technical preparations.

In this book expert authors from around the world contribute comprehensive, up-to-date reviews on the current state of our knowledge of bacterial endospores. Topics covered include: gene regulation of sporulation, fruiting body development in Myxococcus xanthus, sporulation in Streptomyces, structure and composition of the bacterial spore, mechanisms of spore survival, germination of spores, spore peptidoglycan degradation, water and cations flux during sporulation and germination, the spore as an infectious agent, heterogeneity in spore populations, detection of bacterial spores, and the expr.
