Book Description
Dr. Joshua Lederberg - scientist, Nobel laureate, visionary thinker, and friend of the Forum on Microbial Threats - died on February 2, 2008. It was in his honor that the Institute of Medicine's Forum on Microbial Threats convened a public workshop on May 20-21, 2008, to examine Dr. Lederberg's scientific and policy contributions to the marketplace of ideas in the life sciences, medicine, and public policy. The resulting workshop summary, Microbial Evolution and Co-Adaptation, demonstrates the extent to which conceptual and technological developments have, within a few short years, advanced our collective understanding of the microbiome, microbial genetics, microbial communities, and microbe-host-environment interactions.

Book Description
Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.

Book Description
The use of microbial plant protection products is growing and their importance will strongly increase due to political and public pressure. World population is growing and the amount of food needed by 2050 will be double of what is produced now whereas the area of agricultural land is decreasing. We must increase crop yield in a sustainable way. Chemical plant growth promoters must be replaced by microbiological products. Also here, the use of microbial products is growing and their importance will strongly increase. A growing area of agricultural land is salinated. Global warming will increase this process. Plants growth is inhibited by salt or even made impossible and farmers tend to disuse the most salinated lands. Microbes have been very successfully used to alleviate salt stress of plants. Chemical pollution of land can make plant growth difficult and crops grown are often polluted and not suitable for consumption. Microbes have been used to degrade these chemical pollutants.

Book Description
Recent developments in various “OMICs” fields have revolutionized our understanding of the vast diversity and ubiquity of microbes in the biosphere. However, most of the current paradigms of microbial cell biology, and our view of how microbes live and what they are capable of, are derived from in vitro experiments on isolated strains. Even the co-culturing of mixed species to interrogate community behavior is relatively new. But the majority of microorganisms lives in complex communities in natural environments, under varying conditions, and often cannot be cultivated. Unless we obtain a detailed understanding of the near-native 3D ultrastructure of individual community members, the 3D spatial community organization, their metabolic interdependences, coordinated gene expression and the spatial organization of their macromolecular machines inventories as well as their communication strategies, we won’t be able to truly understand microbial community life. How spatial and also temporal organization in cell–cell interactions are achieved remains largely elusive. For example, a key question in microbial ecology is what mechanisms microbes employ to respond when faced with prey, competitors or predators, and changes in external factors. Specifically, to what degree do bacterial cells in biofilms act individually or with coordinated responses? What are the spatial extent and coherence of coordinated responses? In addition, networks linking organisms across a dynamic range of physical constraints and connections should provide the basis for linked evolutionary changes under pressure from a changing environment. Therefore, we need to investigate microbial responses to altered or adverse environmental conditions (including phages, predators, and competitors) and their macromolecular, metabolic responses according to their spatial organization. We envision a diverse set of tools, including optical, spectroscopical, chemical and ultrastructural imaging techniques that will be utilized to address questions regarding e.g. intra- and inter-organism interactions linked to ultrastructure, and correlated adaptive responses in gene expression, physiological and metabolic states as a consequence of the alterations of their environment. Clearly strategies for co-evolution and in general the display of adaptive strategies of a microbial network as a response to the altered environment are of high interest. While a special focus will be placed on terrestrial sole-species or mixed biofilms, we are also interested in aquatic systems, biofilms in general and microbes living in symbiosis. In this Research Topic, we wish to summarize and review results investigating interactions and possibly networks between microbes of the same or different species, their co-occurrence, as well as spatiotemporal patterns of distribution. Our goal is to include a broad spectrum of experimental and theoretical contributions, from research and review articles to hypothesis and theory, aiming at understanding microbial interactions at a systems level.

Book Description
Although we can't usually see them, microbes are essential for every part of human life-indeed all life on Earth. The emerging field of metagenomics offers a new way of exploring the microbial world that will transform modern microbiology and lead to practical applications in medicine, agriculture, alternative energy, environmental remediation, and many others areas. Metagenomics allows researchers to look at the genomes of all of the microbes in an environment at once, providing a "meta" view of the whole microbial community and the complex interactions within it. It's a quantum leap beyond traditional research techniques that rely on studying-one at a time-the few microbes that can be grown in the laboratory. At the request of the National Science Foundation, five Institutes of the National Institutes of Health, and the Department of Energy, the National Research Council organized a committee to address the current state of metagenomics and identify obstacles current researchers are facing in order to determine how to best support the field and encourage its success. The New Science of Metagenomics recommends the establishment of a "Global Metagenomics Initiative" comprising a small number of large-scale metagenomics projects as well as many medium- and small-scale projects to advance the technology and develop the standard practices needed to advance the field. The report also addresses database needs, methodological challenges, and the importance of interdisciplinary collaboration in supporting this new field.
