This book was released on 2003-04-30 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilms are of great practical importance for beneficial technologies such as water and wastewater treatment and bioremediation of groundwater and soil. In other settings biofilms cause severe problems, for example in 65% of bacterial infections currently treated by clinicians (particularly those associated with prosthetics and implants), accelerated corrosion in industrial systems, oil souring and biofouling. Until recently, the structure and function of biofilms could only be inferred from gross measures of biomass and metabolic activity. This limitation meant that investigators involved in biofilm research and application had only a crude understanding of the microbial ecology, physical structure and chemical characteristics of biofilms. Consequently, opportunities for the exploitation and control of biofilms were very limited. The past decade has witnessed the development of several new techniques to elucidate the structure and function of biofilms. Examples include: the use of molecular probes that identify different microbes in complex communities as well as their metabolic functions; the use of microsensors that show concentration gradients of key nutrients and chemicals; the use of confocal laser scanning microscopy to describe the physical structure of biofilms and the development of a new generation of mathematical models that allow for the prediction of biofilm structure and function. However, much progress remains to be made in efforts to understand, control and exploit biofilms. This timely book will introduce its readers to the structure and function of biofilms at a fundamental level as determined during the past decade of research, including: Extracellular polymers as the biofilm matrix; Biofilm phenotype (differential gene expression, interspecies signalling); Biofilm ecology; Biofilm monitoring; Resistance of biofilms to antimicrobial agents and Biofilm abatement. Biofilms in Medicine, Industry and Environmental Technology offers a holistic and multi-disciplinary description of the topic, including biofilm formation and composition, but also biofilm monitoring, disinfection and control. All these aspects are presented from three points of views: medical, industrial and environmental biotechnological in a compact, easy to read format.
Download or read book Biofilm Structure and Activity written by Z. Lewandowski and published by IWA Publishing. This book was released on 2005-05-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilm research now covers a wide diversity of fields within environmental, industrial and biomedical research, such that it can be difficult to grasp its entire scope. The 2004 biofilms conference was therefore structured as an opportunity not only to present recent advances, but also to summarize our knowledge of biofilm processes, define gaps in understanding, and suggest directions of future explorations. The primary focus was how biofilm structure and activity can be correlated. Much work has been done recently in quantifying relations between biofilm structure and the rates of various biofilm processes, such as microbial growth and detachment; this has developed to a major field of exploration in biofilm engineering, and it affects many other fields of biofilm research. After a full-length editorial by acknowledged experts in biofilm research that provides an informed overview of recent accomplishments and remaining challenges, 34 papers are included, selected following full peer review. They report recent work on biofilm structure, bioremediation, biofilm reactors, modelling, and biofilm ecology. These papers will prove invaluable to research scientists, environmental and sanitary engineers and together they represent a genuine state-of-the-art summary of methods and results in biofilm research and its applications in wastewater treatment and environmental engineering.
Download or read book Bacterial Biofilms written by Tony Romeo and published by Springer Science & Business Media. This book was released on 2008-02-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the biological world, bacteria thrive predominantly in surface-attached, matrix-enclosed, multicellular communities or biofilms, as opposed to isolated planktonic cells. This choice of lifestyle is not trivial, as it involves major shifts in the use of genetic information and cellular energy, and has profound consequences for bacterial physiology and survival. Growth within a biofilm can thwart immune function and antibiotic therapy and thereby complicate the treatment of infectious diseases, especially chronic and foreign device-associated infections. Modern studies of many important biofilms have advanced well beyond the descriptive stage, and have begun to provide molecular details of the structural, biochemical, and genetic processes that drive biofilm formation and its dispersion. There is much diversity in the details of biofilm development among various species, but there are also commonalities. In most species, environmental and nutritional conditions greatly influence biofilm development. Similar kinds of adhesive molecules often promote biofilm formation in diverse species. Signaling and regulatory processes that drive biofilm development are often conserved, especially among related bacteria. Knowledge of such processes holds great promise for efforts to control biofilm growth and combat biofilm-associated infections. This volume focuses on the biology of biofilms that affect human disease, although it is by no means comprehensive. It opens with chapters that provide the reader with current perspectives on biofilm development, physiology, environmental, and regulatory effects, the role of quorum sensing, and resistance/phenotypic persistence to antimicrobial agents during biofilm growth.
Download or read book Recent Advances in Bacterial Biofilm Studies written by Liang Wang and published by BoD – Books on Demand. This book was released on 2024-02-28 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial biofilm is a complex structure with diverse bacterial cells in a highly organized and ordered group within a matrix of extracellular polymeric substances they produce. Microbes attach to surfaces to develop biofilms, a sophisticated process regulated by factors such as nutritional status and biotic/abiotic surface features. An established biofilm structure mainly comprises bacterial cells, proteins, nucleic acid, and exo-polysaccharides that are extracellular macromolecules excreted as tightly bound layers in microbes, providing a perfect niche for bacteria to exchange genetic material between cells. In addition, bacterial cells in the matrix also communicate via quorum sensing, which greatly impacts biofilm processes. Under clinical circumstances, bacterial biofilm shows great resistance to antibiotics, disinfectants, and body defense systems, making it difficult for clinicians to eradicate and facilitate many infectious disease processes, leading to chronic infections of patients with long-term hospitalization and high mortality rates. Therefore, it is very important to understand the recent advances in forming, regulating, and eradicating biofilms in human infections to better prevent, control, and treat biofilm infections in humans. Written by an international team of basic and clinical researchers, the chapters of this book provide novel insights and advanced knowledge for life science researchers, clinical researchers, doctors, and other interested readers on some of the latest developments in biofilms.

Download or read book Medical Implications of Biofilms written by Michael Wilson and published by Cambridge University Press. This book was released on 2003-09-01 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human tissues often support large, complex microbial communities growing as biofilms that can cause a variety of infections. As a result of an increased use of implanted medical devices, the incidence of these biofilm-associated diseases is increasing: the non-shedding surfaces of these devices provide ideal substrata for colonisation by biofilm-forming microbes. The consequences of this mode of growth are far-reaching. As microbes in biofilms exhibit increased tolerance towards antimicrobial agents and decreased susceptibility to host defence systems, biofilm-associated diseases are becoming increasingly difficult to treat. Not surprisingly, therefore, interest in biofilms has increased dramatically. The application of microscopic and molecular techniques has revolutionised our understanding of biofilm structure, composition, organisation, and activities, resulting in important advances in the prevention and treatment of biofilm-related diseases. The purpose of this book, which was first published in 2003, is to bring these advances to the attention of clinicians and medical researchers.

Download or read book Biofilms written by Hans-Curt Flemming and published by CRC Press. This book was released on 2000-06-23 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now, techniques for studying biofilms- the cellular colonies that live in drinking water systems, wastewater operations, even ground and surface water- have been limited. Yet during the last decade, biofilms have become a critical element in water quality preservation systems, a key component of wastewater treatment biological reactions and the subject of extensive microbiological inquiry. An understanding of biofilm development, structure and dynamics is one condition for improving water supplies and for addressing technical problems such as biofouling, corrosion and bioweathering. Biofilms: Investigative Methods and Applications provides the first in-depth assessment of current and experimental ways to study biofilms, both in sample form and in situ. It shows how sensors, microscopy, lasers, and calorimetry, among other tools, can be used to obtain data on the morphology and metabolism of biofilms. This text is the first to organize and examine the best methods for investigating biofilms. It covers culture-based methods and emerging nondestructive techniques. It also shows how they can be used to characterize biofilms in a variety of manmade settings, such as sewers, wastewater plants, and drinking water distribution systems, as well as in karsts and groundwater sources. In clarifying the way biofilms are studied, the book offers new insights into these living films. It also applies inquiry techniques to the many problems confronting the environmental specialist-corrosion control, biofouling, and the improvement of fixed reactors in wastewater treatment. At the same time it explains technologies for the controlled growth of biofilms and shows how biofilms can be effectively monitored and subjected to quantitative analysis. The technical information in Biofilms: Investigative Methods and Applications is designed to be of use to engineers and researchers and to be helpful in the generation of electronic data.

Available in PDF, EPUB and Kindle. Book excerpt: Biofilms are predominant mode of life for microbes under natural conditions. The three-dimensional structure of the biofilm provides enhanced protection from physical, chemical and biological stress conditions to associated microbial communities. These complex and highly structured microbial communities play a vital role in maintaining the health of plants, soils and waters. Biofilm associated with plants may be pathogenic or beneficial based on the nature of their interactions. Pathogenic or undesirable biofilm requires control in many situations, including soil, plants, food and water. Written by leading experts from around the world, Biofilms in Plant and Soil Health provides an up-to-date review on various aspects of microbial biofilms, and suggests future and emerging trends in biofilms in plant and soil health. Issues are addressed in four sub areas: I) The fundamentals and significance of biofilm in plant and soil health, and the concept of mono and mixed biofilms by PGPR and fungal biofilms. II) Biochemical and molecular mechanisms in biofilm studies in plant associated bacteria, and techniques in studying biofilms and their characterization, gene expression and enhanced antimicrobial resistance in biofilms, as well as biotic and biotic factors affecting biofilm in vitro. III) The ecological significance of soil associated biofilms and stress management and bioremediation of contaminated soils and degraded ecosystems. IV) Pathogenic biofilm associated with plant and food and its control measures. This book is recommended for students and researchers working in agricultural and environmental microbiology, biotechnology, soil sciences, soil and plant health and plant protection.
