Microbial populations have traditionally been studied in carefully controlled, laboratory-grown cultures. New metagenomic approaches are being developed to study these organisms in environmental or medical samples. The July issue of Cold Spring Harbor Protocols (www.cshprotocols.org/TOCs/toc7_09.dtl) presents a method developed by Holger Daims from the University of Vienna (http://www.microbial-ecology.net/daims.asp) for quantifying populations of microorganisms in a variety of naturally...

ATLANTA, May 21 /PRNewswire/ - With the Alberta Government's May 20th announcement of its contribution towards 2 new genomics projects, Genome Alberta has completed the funding puzzle and is pleased to announce these new and very special projects that will play a leading role in genomic research. Helping Energy Extraction Become a Little Bit Greener: Deep inside the world's hydrocarbon deposits are naturally occurring microbes that have been hard at work for untold years. These microbes...

CAMBRIDGE, Mass. -- An ingenious new method of obtaining marine microbe samples while preserving the microbes' natural gene expression has yielded an unexpected boon: the presence of many varieties of small RNAs "” snippets of RNA that act as switches to regulate gene expression in these single-celled creatures. Before now, small RNA could only be studied in lab-cultured microorganisms; the discovery of its presence in a natural setting may make it possible finally to learn on a broad...

Scientists from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) and the Bigelow Laboratory for Ocean Sciences have assembled high quality, contamination-free draft genomes of uncultured biodegrading microorganisms using a novel single cell genome sequencing approach. This proof of principle study, published in the April 23 edition of the journal PLoS One, offers researchers a new method to access and decipher the information embedded in genomes of interest with only minute...

Taking a hint from the text comparison methods used to detect plagiarism in books, college papers and computer programs, University of California, Berkeley, researchers have developed an improved method for comparing whole genome sequences. With nearly a thousand genomes partly or fully sequenced, scientists are jumping on comparative genomics as a way to construct evolutionary trees, trace disease susceptibility in populations, and even track down people's ancestry. To date, the most common...

In an upcoming issue of Proceedings of the National Academy of Sciences, Yale researchers used newly developed mathematical models to analyze huge amounts of data on physical characteristics such as temperature and salinity in different ocean habitats and metabolic activity in marine micro-organisms. They were able to see in unprecedented detail how environment influences molecular changes within living organisms. As the technology dubbed "metagenomics" progresses, scientists might be able to...

The study of ancient microbes may not seem consequential, but such pioneering research at the University of Oklahoma has implications for the state of modern human health. Cecil Lewis, assistant professor in the Department of Anthropology, says results of this research raise questions about the microbes living on and within people. A National Institutes of Health initiative is looking at helpful bacteria found on the skin, in the esophagus and in the stomach, by characterizing the microbe's...

An international team led by a U.S. researcher has completed genome sequencing for an extinct animal, offering insight into its modern-day cousin. Using DNA extracted from samples of the pre-historic woolly mammoth's hair, Pennsylvania State University biology Stephan Schuster and his 20 teammates collected the near-complete nuclear genome, the team reported in the journal Nature Wednesday. Samples from several different mammoth species preserved in permafrost were used in the sequencing...

Using the Genome Sequencer System from 454 Life Sciences, a Roche company, French scientists have identified a small virus that can actually be parasitic to a larger one. The 50 nm virus, named Sputnik, is associated with a new strain of the giant Acanthamoeba polyphaga mimivirus (APMV) and is believed to represent a currently unknown family of viruses. The study, entitled "The virophage as a unique parasite of the giant mimivirus," appeared in the September 4th issue of Nature (1). The...

By Drenovsky, Rebecca E Feris, Kevin P; Batten, Katharine M; Hristova, Krassimira ABSTRACT.- Interest in the relationships between soil microbial communities and ecosystem functions is growing with increasing recognition of the key roles microorganisms play in a variety of ecosystems. With a wealth of microbial methods now available, selecting the most appropriate method can be daunting, especially to those new to the field of microbial ecology. In this review, we highlight those methods...
