Metagenomics has proven to be a powerful tool for exploring the ecology, metabolic profiling, and comparison of complex microbial communities as well as its important applications in the mining of metagenomes for genes encoding novel biocatalysts and drug molecules for bioindustries. In Metagenomics: Methods and Protocols, expert researches provide an overview and introduction to basic methods commonly used in laboratories that have a strong background in microbial metagenomics. The book attempts to address all of the working steps involved in this crucial field, beginning with DNA isolation from soils and marine samples and continuing with the construction and screening of libraries, along with key advise involving bioinformatic tools available to analyze large metagenomic sequence data sets. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include brief introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Metagenomics: Methods and Protocols serves as a very complete guide to available screening protocols for all major biocatalysts in order to allow for the easy setup of these screens in any microbiology lab.

Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent."

This Volume covers protocols for various applications in hydrocarbon microbiology, including those of interest for industrial processes, biocatalysis, lipid and biofuel production, bioproducts, or the human microbiome. It presents detailed protocols for the functional screening of enzymes acting on greasy molecules (i.e. lipases, esterases), including assays for enantioselective biocatalysts, as well as approaches for protein display technologies. Protocols for improving fuel quality and production of biofuel and lipids in different hosts (bacteria, algae, yeast) are also provided. The production of biogas from organic waste and its fermentation into value-added products such as polyhydroxyalkanoates is covered, as well as an in-vitro model of the gut microbiome for short-chain fatty acid metabolism and microbial diversity analyses. The applications presented are examples of the many potential applications in hydrocarbon and lipid microbiology, and many (i.e. protein-display technologies) will also be of interest in other research fields. Hydrocarbon and Lipid Microbiology Protocols There are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

This text features the proceedings of a workshop on Advances in Biological Treatment of Lignocellulosic Materials, held in Lisbon, Portugal, during 25-27 October 1989.

This book describes how microbes can be used as effective and sustainable resources to meet the current challenge of finding suitable and economical solutions for biopharmaceuticals, enzymes, food additives, nutraceuticals, value added biochemicals and microbial fuels, and discusses various aspects of microbial regulatory activity and its applications. It particularly focuses on the design, layout and other relevant issues in industrial microbe applications. Moreover, it discusses the entire microbial-product supply chain, from manufacturing sites to end users, both in domestic and international markets, providing insights into the global marketing of microbes and microbial biomass-derived products. Further, it includes topics concerning the effective production and utilization of eco-friendly biotechnology industries. It offers a valuable, ready-to-use guide for technologists and policymakers developing new biotechnologies.

These proceedings bring together diverse disciplines that study nitrogen fixation and describe the most recent advances made in various fields: chemists are now studying FeMoco, the active site of nitrogenase in non-protein surroundings, and have refined the crystal structure of the enzyme to 1.6 angstroms.

In this timely book, expert international authors critically review all of the most important topics in this exciting field. This book is unique in that it is the first to review the area from a molecular biology and genomics perspective. Topics covered include: aerobic and anaerobic biodegradation of aromatic compounds; molecular detection methods (e.g. microautoradiography, mRNA analyses, etc.); genome-based predictive modeling; elucidation of regulatory networks; bioavailability; chemotaxis and transport issues; functional genomic analyses; natural attenuation; community fingerprinting and metagenomics; biotreatment; and biocatalysts engineering. The book will be essential reading for microbial degradation and bioremediation scientists, and of general interest for microbiologists working in field of environmental microbiology.

The refinement of molecular techniques and the development of new probes of the phylogeny of diazotrophs has revealed an extreme biodiversity among the nitrogen fixers, which helps explain the role that nitrogen fixation plays in maintaining life on Earth. The most efficient ecosystems are those where the bacteria are associated with a plant in differentiated organs to benefit crop productivity. Most short-term benefit from fundamental research on nitrogen fixation is likely to result in the improvement of existing nitrogen-fixing symbiotic or associative systems. Longer-term efforts are aimed at extending the nitrogen-fixing capacity to other organisms, including transfer of the genetic information for efficient nitrogen fixation into the plant genome and using current knowledge of microbe-plant interactions to extend symbiosis to cereals and, in particular, to rice. Related challenges in sustainable agriculture and forestry include the creation of new nitrogen-fixing associations. All of these approaches were discussed at the 11th International Congress on Nitrogen Fixation, Paris, France, July 20-25, 1997 and covered in the present proceedings volume.

"This water" he told me, "runs out to the eastern region, and flows into the Arabah; and when it comes into the sea, into the sea of foul waters [i. e. , the Dead Sea], the water will become wholesome. Every living creature that swarms will be able to live wherever this stream goes; the fish will be very abundant once these waters have reached there. It will be wholesome, and everything will live wherever this stream goes. Fishermen shall stand beside it all the way from En-gedi to En-eglaim; it shall be a place for drying nets; and the fish will be of various kinds [and] most plentiful, like the fish of the Great Sea. " Ezekiel's prophecy (Ezekiel 47: 8-10) for revival and purification of the Dead Sea waters This new book on "Halophilic Microorganisms and their Environments" is the fifth volume in the COLE series (Cellular Origin and Life in Extreme Habitats (see: http://www. wkap. nl/prod/s/COLE). In the previous books we covered aspects of enigmatic microorganisms, microbial diversity, astrobiology, and symbiosis, so this book on halophilic microbes adds a fitting link to the rest of series' books. Since ancient times hypersaline habitats have been considered extreme environments, and some were thought not to sustain life at all. Yet, every organism requires salt for its existence. Salty places have been compared to an environment of extinction (e. g. , the Dead Sea).

Antimicrobial resistance is recognised among the world’s most challenging problems. Despite its global spread, Africa, specifically sub-Saharan Africa, is the most affected by this malaise. Poor living conditions and inadequate access to sanitation and potable water supplies are among contributing factors that have influenced a high disease burden on the continent, requiring extensive antimicrobials. Weak health systems and the absence of firm policies further aggravate the problem, as the use of antimicrobials is mostly unregulated. The increasing demand for animal protein to meet the starving populations’ demands has also influenced the use of these antimicrobials, including those banned on other continents, for food animal production. The ripple effect of indiscriminate use in humans and animals is the massive discharge of antimicrobials, their residues, antimicrobial-resistant microorganisms and their associated genes into the environment.  This 14-chapter unique masterpiece presents the AMR problem in African, addressing the various compartments of the One Health – humans, animals, and the environment, to illustrate the need for concerted efforts in the fight against AMR, especially in Africa. Authors from the four cardinal points present diverse aspects of AMR in Africa, starting with behavioural and social drivers of AMR in Africa. Antimicrobial stewardship in an African context is also discussed. AMR in humans is presented through studies on antibiotic-resistant neonates and nontyphoidal Salmonella infections and the clinical relevance of the genetics of viral resistance. Topics on AMR in mastitis, biosecurity in animal farming and the linkage between disinfectants and AMR are discussed. The environmental dimension of AMR is discussed, notably in the aquatic environment, and its implication for aquaculture and irrigation and using nanomaterials to treat polluted waters from such environments are highlighted. Finally, Africa’s rich floral diversity is portrayed as an eco-friendly and cost-effective approach to combat AMR. Hopefully, the work presented will spur greater collaboration between scientists, environmental, animal and human health practitioners, the general population, and policymakers to assimilate and implement the One Health approach to combating AMR, rather than working in silos on their various sectors

Plant roots may not only be colonized by mycorrhizal fungi, but also by a myriad of bacterial and fungal root endophytes that are usually not considered by the investigators of classic symbioses. This is the first book dedicated to the interactions of non-mycorrhizal microbial endophytes with plant roots.

The phenotypes of these interactions can be extremely plastic, depending on environmental factors, nutritional status, genetic disposition and developmental stages of the two partners. The book deals with diversity, life history strategies, interactions, applications in agriculture and forestry, methods for isolation, cultivation, and both conventional and molecular methods for identification and detection of these endophytes. The comprehensive reviews demonstrate the high diversity of interactions and will provoke further studies to better understand the mechanisms which determine whether a plant-microbial interaction remains asymptomatic, leads to disease or to a mutualistic interaction.

Linear plasmids of microbes represent a heterogenous group of extrachromosomal genetic elements initially assumed to be rare and peculiar. However, we now know that they are fairly frequently occurring plasmids in bacterial and eukaryotic species. Viral strategies to avoid shortening of the linear molecules during replication imply a common ancestry. Linear plasmids may be beneficial, neutral or detrimental for the respective host; functions include production of protein toxins, specific catabolic capabilities, antibiotic resistance, pathogenicity factors, and senescence induction.

Microbial Linear Plasmids constitutes the first attempt to comprehensively assemble current knowledge of different types of such elements, highlight recent developments in the field, and challenge the distinction between viruses and linear plasmids.

The new series "Microbiology Monographs" begins with two volumes on intracellular components in prokaryotes. In this second volume, "Complex Intracellular Structures in Prokaryotes," the components, labeled complex intracellular structures, encompass a multitude of important cellular functions. Continuing and newly initiated research will provide a clearer understanding of the complex intracellular structures known at present and will bring to light surprising new ones as well.

In this book we present ten chapters describing the synthesis and application of nanomaterials for health, food, agriculture and bioremediation. Nanomaterials, with unique properties are now being used to improve food and agricultural production. Research on nanomaterials is indeed revealing new applications that were once thought to be imaginary. Specifically, applications lead to higher crop productivity with nanofertilisers, better packaging, longer food shelf life and better sensing of aromas and contaminants. these applications are needed in particular in poor countries where food is scarce and the water quality bad. Nanotechnology also addresses the age old issue of water polluted by industrial, urban and agricultural pollutants. For instance, research produces nanomaterials that clean water more efficiently than classical methods, thus yielding water for drinking and irrigation. However, some nanomaterials have been found to be toxic. Therefore, nanomaterials should be engineered to be safe for the environment.

Extremophiles belong to members of all three domains of life, i.e., bacteria, archaea, and eukarya. However, a high proportion of extremophiles are archaea and bacteria. These microbes live under chemical and physical extremes that are usually lethal to cellular molecules, yet they not only manage to survive but even thrive in such conditions. Extremophiles have important practical and industrial uses. They are a valuable source of industrially important enzymes also known as extremozymes. Recent research has revealed that extremozymes have unique structural features essential for biocatalysis under extreme conditions. Extremozymes have great commercial values and are known for their potential use in biotechnology, biomining, and bioremediation. Extremozymes and their Industrial Applications highlights the current and topical areas of research in this rapidly growing field of extremophiles and their applications. Expert researchers from around the globe are trying to uncover the underlying mechanisms responsible for their specific adaptations under extreme environments. The topics covered include the ability of acidophiles to maintain a neutral intracellular pH, the way psychrophiles "loosen up" their proteins at low temperatures, and other equally ingenious adaptations and metabolic strategies that extremophiles use to survive and flourish under extreme conditions. Extremozymes and their Industrial Applications also covers the established biotechnological uses of extremophiles and the most recent and novel applications, including their exploitation for enzyme production. Potential use of extremophiles and their enzymes in the generation of sustainable energy, biomass conversion, agro-waste processing, and biocontrol of phytopathogens is also covered. The book will be very useful for researchers and students working in the area of industrial microbiology and biotechnology, and microbial ecologists. It is also recommended reference text for those interested in the biochemistry and microbiology of extremophiles, as well as for those interested in bioprospecting, biomining, biofuels, and biodegradation.

This volume presents a critical analysis and timely synthesis of the past decade of intensive research, development, and demonstrations on the in situ bioremediation of perchlorate in groundwater. The intended audiences include the decision makers, practicing engineers and hydrogeologists who will select, design, and operate these remedial systems, as well as researchers seeking to improve the current state-of-the-art. Our hope is that this volume will serve as a useful resource to assist remediation professionals in applying and developing the technology as effectively as possible. An overview of the current state-of-understanding of perchlorate remediation is followed by a discussion of basic principles of microbial and abiotic processes, and of the engineering and implementation issues underlying the technologies described. Characterization of both anthropogenic and natural sources of perchlorate, including isotopic analysis to distinguish between differing sources, precedes discussions of the advantages, performance, and relative costs of applying a range of remedial technologies. Active, semi-passive, and passive in situ bioremediation are fully described and compared with emphasis on field application. Cost information for each technology, using case studies and analyses of several template sites, covers capital costs, as well as costs for laboratory testing, pilot-scale demonstration, design, system operation, monitoring and maintenance during operations, and demolition and restoration after remediation. In addition, analogous cost data are presented for pump-and-treat systems for each template site to illustrate the potential cost savings associated with the use of alternative approaches. Emerging technologies such as monitored natural attenuation, phytoremediation, and vadose zone bioremediation are described, and field demonstrations are used to illustrate the current stage of maturity and the potential applicability of these approaches for specific situations. Each chapter in this volume has been thoroughly reviewed for technical content by one or more experts in each subject area covered.

Advanced Mathematical Modelling of Biofilms and its Applications covers the concepts and fundamentals of biofilms, including sections on numerical discrete and numerical continuum models and different biofilms methods, e.g., the lattice Boltzmann method (LBM) and cellular automata (CA) and integrated LBM and individual-based model (iBM). Other sections focus on design, problem-solving and state-of-the-art modelling methods. Addressing the needs to upgrade and update information and knowledge for students, researchers and engineers on biofilms in health care, medicine, food, aquaculture and industry, this book also covers areas of uncertainty and future needs for advancing the use of biofilm models. Over the past 25-30 years, there have been rapid advances in various areas of computer technologies, applications and methods (e.g. complex programming and algorithms, lattice Boltzmann method, high resolution visualization and high-performance computation). These new and emerging technologies are providing unprecedented opportunities to develop modeling frameworks of biofilms and their applications.
