Book Description
Vibrational spectroscopy techniques, which have traditionally been used to provide non-destructive, rapid, and relevant information on microbial systematics, are useful for classification and identification. In conjunction with advanced chemometrics, infrared spectroscopy enables the biochemical signatures from microbiological structures to be extracted and analysed. In addition, a number of recent studies have shown that Fourier Transform Infrared (FT-IR) spectroscopy can help to understand the molecular basis of events, such as the adaptive tolerance responses expressed by bacteria when exposed to stress conditions in the environment, i.e. environments that cells confront in food and during food processing. The proposed Brief will discuss the published experimental techniques, data-processing algorithms, and approaches used in FT-IR spectroscopy to assist in the characterization and identification of microorganisms, to assess the mechanisms of bacterial inactivation by food processing technologies and antimicrobial compounds, to monitor the spore and membrane properties of foodborne pathogens in changing environments, to detect stress-injured microorganisms in food-related environments, to assess dynamic changes in bacterial populations, and to study bacterial tolerance responses.

Book Description
Bacterial taxonomy as a specialized discipline is practised by a minority but the applications of taxonomy are important to most, if not all microbiologists. It is the implementation of taxonomic ideas and practises which gives rise to identification and typing systems, procedures for the analysis and characterization of biodiversity, hypotheses about the evolution of micro-organisms, and improved procedures for the isolation and implementation of bacteria in biotechnological processes. Without taxonomic theory providing a sound basis to these many facets of microbiology there would be severe problems faced by many scientists working with micro-organisms. Taxonomy comprises three sequential but independent processes; classification, nomenclature and identification. The first two stages are the prime concern of the specialist taxonomist but the third stage should result in identification schemes of value to all microbiologists. As the classification and identification of micro-organisms improves, largely due to the introduction of new technologies, so does its contribution to the subject as a whole. It therefore seemed timely to hold a conference in the autumn of 1993 devoted to microbial identification. Such a topic could not be addressed without some reference to the enabling discipline of classification, but the principal aims were to assess improvements in identification and typing and how these were benefiting microbiological topics ranging from ecological and biotechnological studies of extremophilic bacteria to the use of pyrolysis mass spectrometry in epidemiology. The meeting, which was held in Granada, Spain, was supported by FEMS (FEMS Symposium No.

Book Description
The golden era of food microbiology has begun. All three areas of food microbiology—beneficial, spoilage, and pathogenic microbiology—are expanding and progressing at an incredible pace. What was once a simple process of counting colonies has become a sophisticated process of sequencing complete genomes of starter cultures and use of biosensors to detect foodborne pathogens. Capturing these developments, Fundamental Food Microbiology, Fifth Edition broadens coverage of foodborne diseases to include new and emerging pathogens as well as descriptions of the mechanism of pathogenesis. Written by experts with approximately fifty years of combined experience, the book provides an in-depth understanding of how to reduce microbial food spoilage, improve intervention technologies, and develop effective control methods for different types of foods. See What’s New in the Fifth Edition: New chapter on microbial attachment and biofilm formation Bacterial quorum sensing during bacterial growth in food Novel application of bacteriophage in pathogen control and detection Substantial update on intestinal beneficial microbiota and probiotics to control pathogens, chronic diseases, and obesity Nanotechnology in food preservation Description of new pathogens such as Cronobacter sakazaki, E. coli O104:H4, Clostridium difficile, and Nipah Virus Comprehensive list of seafood-related toxins Updates on several new anti-microbial compounds such as polylysine, lactoferrin, lactoperoxidase, ovotransferrin, defensins, herbs, and spices Updates on modern processing technologies such as infrared heating and plasma technology Maintaining the high standard set by the previous bestselling editions, based feedback from students and professors, the new edition includes many more easy-to-follow figures and illustrations. The chapters are presented in a logical sequence that connects the information and allow students to easily understand and retain the concepts presented. These features and more make this a comprehensive introductory text for undergraduates as well as a valuable reference for graduate level and working professionals in food microbiology or food safety.

Book Description
One of the most important emerging aspects that requires further research in food safety is the simultaneous presence of different contaminants (both microbiological and chemical) in the same food, the so-called “cocktail effect”. Large amounts of data are needed for these evaluations, since the huge number of interactions among different contaminants, which maybe hypothesized, have to be statistically evaluated before confirming an effective risk. Moreover, the range of food to take into account within these studies is very wide. In order to obtain comprehensive datasets, new approaches are needed. These approaches, composed of new analytical procedures, microbiological protocols and chemical/physical determinations, should allow the quick and economic obtainment of many parameters, possibly respecting the environment, in the “green chemistry” perspective.
