Foods fermented with lactic acid bacteria are an important part of the human diet. Lactic acid bacteria play an essential role in the preservation of food raw materials and contribute to the nutritional, organoleptic, and health properties of food products and animal feed. The importance of lactic acid bacteria in the production of foods throughout the world has resulted in a continued scientific interest in these micro-organisms over the last two decades by academic research groups as well as by industry. This research has resulted in a number of important scientific breakthroughs and has...

Microbes produce an extraordinary array of defense systems. These include bacteriocins, a class of antimicrobial molecules with narrow killing spectra, produced by bacteria. The book describes the diversity and ecological role of bacteriocins of Gram-positive and Gram-negative bacteria, presenting a new classification scheme for the former and a state-of-the-art look at the role of bacteriocins in bacterial communication. It discusses the molecular evolution of colicins and colicin-like bacteriocins, and provides a contemporary overview of archaeocins, bacteriocin-like antimicrobials...

Magnetoreception or magnetotaxis in bacteria was discovered only some 30 years ago. All magnetotactic bacteria, which occur in many environments and display a remarkable diversity, synthesize magnetosomes, complex intracellular organelles that contain magnetic iron crystals.

Recent developments in the research on magnetotactic bacteria are presented in this volume. Included are reviews on the formation and organization of magnetosomes, the genes controlling magnetosome biomineralization, and new cryogenic techniques to visualize novel cytoskeleton structures. Described here are...

"Alginates: Biology and Applications" provides an overview of the state of art of alginate material properties, genetics and the molecular mechanisms underlying alginate biosynthesis as well as applications of tailor-made alginates in medicine, food and biotechnology.

Topics treated are: material properties of alginates, alginate production: precursor biosynthesis, polymerization and secretion, bacterial system for alginate uptake and degradation, enzymatic alginate modification, alginate gene regulation, role of alginate in bacterial biofilms, microbial production of alginates:...

This book details the widely accepted hypothesis that the majority of bacteria in virtually all ecosystems grow in matrix-enclosed biofilms. The author, who first proposed this biofilm hypothesis, uses direct evidence from microscopy and from molecular techniques, arguing cogently for moving beyond conventional culture methods that dominated microbiology in the last century. Bacteria grow predominantly in biofilms in natural, engineered, and pathogenic ecosystems; this book provides a solid basis for the understanding of bacterial processes in environmental, industrial, agricultural,...

During the recent transition between acute diseases caused by swarms of single planktonic bacteria, and chronic infections caused by bacteria growing in slime-enclosed biofilms, a general clinical consensus has emerged that pathologies with bacterial etiologies are frequently culture negative. Because biofilm infections now affect 17 million Americans per year (killing approximately 450,000), the suggestion that these common and lethal infections regularly go unnoticed by the only FDA-approved method for their detection and characterization is a matter of urgent concern. Biologically, we...

This book introduces Planctomycetes bacteria and deals in detail with their unusual structure, physiology, genomics and evolutionary significance. It is a definitive summary of recent knowledge of this important distinctive group of bacteria, microorganisms which challenge our very concept of the bacterium. Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria, including verrucomicrobia and chlamydia, challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full...
