Available in PDF, EPUB and Kindle. Book excerpt: As antibacterial compounds, bacteriocins have always lived in the shadow of those medically important, efficient and often broad-spectrum low-molecular mass antimicrobials, well known even to laypeople as antibiotics. This is despite the fact that bacteriocins were discovered as early as 1928, a year before the penicillin saga started. Bacteriocins are antimicrobial proteins or oligopeptides, displaying a much narrower activity spectrum than antibiotics; they are mainly active against bacterial strains taxonomically closely related to the producer strain, which is usually immune to its own bacteriocin. They form a heterogenous group with regard to the taxonomy of the producing bacterial strains, mode of action, inhibitory spectrum and protein structure and composition. Best known are the colicins and microcins produced by Enterobacteriaceae. Many other Gram-negative as well as Gram-positive bacteria have now been found to produce bacteriocins. In the last decade renewed interest has focused on the bacteriocins from lactic acid bacteria, which are industrially and agriculturally very important. Some of these compounds are even active against food spoilage bacteria and endospore formers and also against certain clinically important (food-borne) pathogens. Recently, bacteriocins from lactic acid bacteria have been studied intensively from every possible scientific angle: microbiology, biochemistry, molecular biology and food technology. Intelligent screening is going on to find novel compounds with unexpected properties, just as has happened (and is still happening) with the antibiotics. Knowledge, especially about bacteriocins from lactic acid bacteria, is accumulating very rapidly.

The new edition also addresses the technological use of LAB in various fermentations of food, feed and beverage, and their safety considerations. It features the detailed description of the main genera of LAB as well as such novel bacteria as fructophilic LAB and novel probiotics and discusses such new targets as cognitive function, metabolic health, respiratory health and probiotics. Key Features: In 12 new chapters, findings are presented on health effects, properties and stability of LAB as well as production of target specific LAB Covers such novel bacteria as fructophilic LAB and novel probiotics Presents new discoveries related to the mechanisms of lactic acid bacterial metabolism and function Covers the benefits of LAB, both in fermentation of dairy, cereal, meat, vegetable and silage, and their health benefits on humans and animals Discusses the less-known role of LAB as food spoilers Covers the global regulatory framework related to safety and efficacy

This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mter the discoveryof the tobacco mosaic virus by D. I. Ivanov skU in 1892 [14], the new science of virology was born and began to develop rapidly. The number of viruses now known is enormous and they can infect nearly all animal and plant organisms. Microorganisms themselves are no exception to this rule. Despite intensive study of Vlruses, their origin and nature are still a subject for speculation and hypothesis. The general concept of viruses embraces a wide group of biologically active structures occupying an intermediate position between living and nonliving matter. The dual character of viruses is determined by the fact that, while they do not possess an inde pendent system of metabolism, which is a characteristic feature of every living being, they nevertheless carry within themselves all the necessary information for autoreproduction. A striking feature of the virus is that it consists essentially of two components: a protein envelope and the nucleic acid con tained within it. In contrast to the elementary structural unit of the living or ganism, the cell, which contains two types of nucleic acid (DNA and RNA), the virus particle contains only one type of nucleic acid - either DNA or RNA. It is perhaps this which is responsible for the imperfection of the virus as a living organism.

Book excerpt: Enological Chemistry is written for the professional enologist tasked with finding the right balance of compounds to create or improve wine products. Related titles lack the appropriate focus for this audience, according to reviewers, failing either to be as comprehensive on the topic of chemistry, to include chemistry as part of the broader science of wine, or targeting a less scientific audience and including social and historical information not directly pertinent to the understanding of the role of chemistry in successful wine production. The topics in the book have been sequenced identically with the steps of the winemaking process. Thus, the book describes the most salient compounds involved in each vinification process, their properties and their balance; also, theoretical knowledge is matched with its practical application. The primary aim is to enable the reader to identify the specific compounds behind enological properties and processes, their chemical balance and their influence on the analytical and sensory quality of wine, as well as the physical, chemical and microbiological factors that affect their evolution during the winemaking process. - Organized according to the winemaking process, guiding reader clearly to application of knowledge - Describes the most salient compounds involved in each step enabling readers to identify the specific compounds behind properties and processes and effectively work with them - Provides both theoretical knowledge and practical application providing a strong starting point for further research and development

Book excerpt: The first edition of Mark Ptashne's 1986 book describing the principles of gene regulation in phage lambda became a classic in both content and form, setting a standard of clarity and precise prose that has rarely been bettered. This edition is a reprint of the original text, together with a new chapter updating the story to 2004. Among the striking new developments are recent findings on long-range interactions between proteins bound to widely separated sites on the phage genome, and a detailed description of how gene activation works.

Available in PDF, EPUB and Kindle. Book excerpt: Despite advances in hygiene, food treatment, and food processing, diseases caused by foodborne pathogens continue to constitute a worldwide public health concern. Ensuring food safety to protect public health remains a significant challenge in both developing and developed nations. Food Safety and Human Health provides a framework to manage food safety risks and assure a safe food system. Political, economic, and ecological changes have led to the re-emergence of many foodborne pathogens. The globalization of food markets, for example, has increased the challenge to manage the microbial risks. This reference will help to identify potential new approaches in the development of new microbiologically safe foods that will aid in preventing food borne illness outbreaks and provides the basic principles of food toxicology, food processing, and food safety. Food Safety and Human Health is an essential resource to help students, researchers, and industry professionals understand and address day-to-day problems regarding food contamination and safety. - Encompasses the first pedagogic treatment of the entire range of toxic compounds found naturally in foods or introduced by industrial contaminatio - Identifies areas of vital concern to consumers, such as toxicological implications of food, and human health implications of food processing - Focuses on safety aspects of genetically modified foods and the range of processing techniques along with the important food safety laws
