Large-Scale Sequencing: The Future of Genomic Sciences Colloquium

Description: Genetic sequencing and the various molecular techniques it has enabled have revolutionized the field of microbiology. Examining and comparing the genetic sequences borne by microbes - including bacteria, archaea, viruses, and microbial eukaryotes - provides researchers insights into the processes microbes carry out, their pathogenic traits, and new ways to use microorganisms in medicine and manufacturing. Until recently, sequencing entire microbial genomes has been laborious and expensive, and the decision to sequence the genome of an organism was made on a case-by-case basis by individual researchers and funding agencies. Now, thanks to new technologies, the cost and effort of sequencing is within reach for even the smallest facilities, and the ability to sequence the genomes of a significant fraction of microbial life may be possible. The availability of numerous microbial genomes will enable unprecedented insights into microbial evolution, function, and physiology. However, the current ad hoc approach to gathering sequence data has resulted in an unbalanced and highly biased sampling of microbial diversity. A well-coordinated, large-scale effort to target the breadth and depth of microbial diversity would result in the greatest impact. The American Academy of Microbiology convened a colloquium to discuss the scientific benefits of engaging in a large-scale, taxonomically-based sequencing project. A group of individuals with expertise in microbiology, genomics, informatics, ecology, and evolution deliberated on the issues inherent in such an effort and generated a set of specific recommendations for how best to proceed. The vast majority of microbes are presently uncultured and, thus, pose significant challenges to such a taxonomically-based approach to sampling genome diversity. However, we have yet to even scratch the surface of the genomic diversity among cultured microbes. A coordinated sequencing effort of cultured organisms is an appropriate place to begin, since not only are their genomes available, but they are also accompanied ...

Uncharted Microbial World: Microbes and Their Activities in the Environment

Description: Microbes are the foundation for all of life. From the air we breathe to the soil we rely on for farming to the water we drink, everything humans need to survive is intimately coupled with the activities of microbes. Major advances have been made in the understanding of disease and the use of microorganisms in the industrial production of drugs, food products and wastewater treatment. However, our understanding of many complicated microbial environments (the gut and teeth), soil fertility, and biogeochemical cycles of the elements is lagging behind due to their enormous complexity. Inadequate technology and limited resources have stymied many lines of investigation. Today, most environmental microorganisms have yet to be isolated and identified, let alone rigorously studied. The American Academy of Microbiology convened a colloquium in Seattle, Washington, in February 2007, to deliberate the way forward in the study of microorganisms and microbial activities in the environment. Researchers in microbiology, marine science, pathobiology, evolutionary biology, medicine, engineering, and other fields discussed ways to build on and extend recent successes in microbiology. The participants made specific recommendations for targeting future research, improving methodologies and techniques, and enhancing training and collaboration in the field. Microbiology has made a great deal of progress in the past 100 years, and the useful applications for these new discoveries are numerous. Microorganisms and microbial products are now used in industrial capacities ranging from bioremediation of toxic chemicals to probiotic therapies for humans and livestock. On the medical front, studies of microbial communities have revealed, among other things, new ways for controlling human pathogens. The immediate future for research in this field is extremely promising. In order to optimize the effectiveness of community research efforts in the future, scientists should include manageable systems with features like clear physical boundaries, limited microbial diversity, and manipulability with ...

ASM Conference on Prokaryotic Development

Description: Support was provided by DOE for the 2nd ASM Conference on Prokaryotic Development. The final conference program and abstracts book is attached. The conference presentations are organized around topics that are central to the current research areas in prokaryotic development. The program starts with topics that involve relatively simple models systems and ends with systems that are more complex. The topics are: i) the cell cycle, ii) the cytoskeleton, iii) morphogenesis, iv) developmental transcription, v) signaling, vi) multicellularity, and vii) developmental diversity and symbiosis. The best-studied prokaryotic development model systems will be highlighted at the conference through research presentations by leaders in the field. Many of these systems are also model systems of relevance to the DOE mission including carbon sequestration (Bradyrizobium, Synechococcus), energy production (Anabaena, Rhodobacter) and bioremediation (Caulobacter, Mesorhizobium). In addition, many of the highlighted organisms have important practical applications; the actinomycetes and myxobacteria produce antimicrobials that are of commercial interest. It is certain that the cutting-edge science presented at the conference will be applicable to the large group of bacteria relevant to the DOE mission.

Microbial Production of Energy Colloquium- March 10-12, 2006

Description: The American Academy of Microbiology convened a colloquium March 10-12, 2006, in San Francisco, California, to discuss the production of energy fuels by microbial conversions. The status of research into various microbial energy technologies, the advantages and disadvantages of each of these approaches, research needs in the field, and education and training issues were examined, with the goal of identifying routes for producing biofuels that would both decrease the need for fossil fuels and reduce greenhouse gas emissions. Currently, the choices for providing energy are limited. Policy makers and the research community must begin to pursue a broader array of potential energy technologies. A diverse energy portfolio that includes an assortment of microbial energy choices will allow communities and consumers to select the best energy solution for their own particular needs. Funding agencies and governments alike need to prepare for future energy needs by investing both in the microbial energy technologies that work today and in the untested technologies that will serve the world’s needs tomorrow. More mature bioprocesses, such as ethanol production from starchy materials and methane from waste digestors, will find applications in the short term. However, innovative techniques for liquid fuel or biohydrogen production are among the longer term possibilities that should also be vigorously explored, starting now. Microorganisms can help meet human energy needs in any of a number of ways. In their most obvious role in energy conversion, microorganisms can generate fuels, including ethanol, hydrogen, methane, lipids, and butanol, which can be burned to produce energy. Alternatively, bacteria can be put to use in microbial fuel cells, where they carry out the direct conversion of biomass into electricity. Microorganisms may also be used some day to make oil and natural gas technologies more efficient by sequestering carbon or by assisting in the recovery of oil ...

3rd ASM Conference on Cell-Cell Communication in Bacteria

Description: This report summarizes the final program and provides the abstracts presented at the fourth American Society of Microbiology-sponsored conference on Cell-cell Communication in Bacteria, held November 6-9, 2011 in Miami, Florida. Bacteria are the paradigm for unicellular life, yet they also exhibit elaborate coordinated behaviors that often defy unicellularity. Research over the past two decades has revealed that a wide range of microbes communicate by diverse mechanisms. In most cases these microbial conversations occur through the exchange of diffusible signals, although there are also clear examples of contact-dependent communication. Many microbes use these signaling mechanisms to monitor and respond to population density, a process often described as quorum sensing. Interbacterial communication is not, however restricted to quorum sensing mechanisms, and there is mounting evidence that signaling can function in a range of different capacities. Communication between microorganisms has profound impacts on host interactions, as pathogens and commensals often regulate factors critical for interaction with their hosts via signal production and perception. The CCCB-4 conference provided a unique forum for the discussion, dissemination and exchange of new information and ideas among researchers working within this rapidly developing, yet mature field. Sessions were arranged around topics such as: the diversity of signal generation and identity; mechanisms of signal transduction and interference; cell-cell communication in bacterial development and antibiotic synthesis; host-microbe signaling and pathogenesis; symbiosis, mutualism, and microbe-microbe communication; ecology and evolution; advancements in the technological tool-kit for studying cell-cell communication. The conference served as a conduit for the exchange and synthesis of new ideas among leading US and international scientists working on bacterial communication.
