Analyzing the Role of DNA Methylation in a Bioremediation Bacterium

Characterizing functional roles in a microbe with bioremediation applications a first step toward similar studies for other prokaryotes The Science Researchers studied the role of DNA methylation on gene expression and other processes in the heavy-metal reducing bacterium Shewanella oneidensis MR-1 with the help of next-generation Single-Molecule Real Time (SMRT) sequencers from Pacific Biosciences. The… [Read More]

Solving the Secrets of Sedimentary Microbes

Microbes from Phylum Chloroflexi Provide Clues to Carbon Cycling, Respiration in Sediments The Science Through metagenomics, researchers sequenced 86 organisms from the phylum Chloroflexi that represent 15 distinct lineages in order to discover the secrets of microbial life within terrestrial aquifer sediment deposits. The Impact These Chloroflexi microbes were found to have metabolic processes involved… [Read More]

Cotton genome project in Central Valley Business Times

“This collaborative effort has yielded a wealth of information that will help scientists better understand the basic biology of cotton and enhance the sustainable production of this globally important crop,” says plant scientist Allen Van Deynze, who led UC Davis’ participation in the sequencing project.

A Gossypium genome to cotton on to cellulose biosynthesis

Growing, processing and manufacturing cotton is a major global industry. In the United States, more than 200,000 domestic jobs are related to cotton production and processing, with an aggregate influence of about $35 billion on the annual U.S. gross domestic product. The fibers that have woven themselves into so many lives, however, are seen by… [Read More]

Cotton genome project in AL.com

If researchers’ plans spin out as they hope, King Cotton may get a new title as a Super Plant of the 21st century…. While most U.S. cotton is used in textile production, researchers say it could become an important part of biofuel production and bioremediation.   Full story at AL.com  [Read More]

Deepwater Horizon oil spill cleanup microbes project in Examiner.com

The first research effort reported in an article published online June 21, 2012, in the ISME Journal involved samples taken immediately after the Deepwater Horizon spill began and during the ensuing clean up efforts.The researchers found that a variety of microbes consumed parts of the oil spill selectively. Each group of microbes specifically targeted one group of… [Read More]

Analysis of a TCE-degrading metagenome

Groundwater sites contaminated with compounds such as trichloroethene (TCE), a pervasive organic groundwater pollutant often used by industry as cleansers or degreasers.Dehalococcoidesbacteria, often found in a community of other microorganisms at groundwater sites contaminated with these compounds, can break down TCE and convert it into ethene, a harmless chemical compound often used to help ripen… [Read More]

Analyzing enzymes for a PAH degradation pathway

Microbial activity is crucial for breaking down compounds, removing pollutants and chemically transforming organic compounds. Some of these pollutants are polycyclic aromatic hydrocarbons (PAHs) found in contaminated soils. The PAH phenanthrene, for example, can be broken down by the bacterium Arthobacterphenanthrenivorans, which was isolated from a creosote-polluted site in Greece, and used by the microbe… [Read More]

DOE JGI science in the Washington Post

JGI director and geneticist Eddy Rubin is a pioneer in the field of “metagenomics,” the study of how the DNA in many creatures can work together to create ecosystems. Right now, he and his team are studying microbes that live in a cow’s rumen, the stomach-like organ that the animals use to break down grasses… [Read More]

A metagenomic approach to analyzing rice endophytes

During the call for 2012 proposals for the DOE JGI’s Community Sequencing Program, one of the areas of focus researchers were asked to consider was that of plant-microbe interactions. Microbes that live in plants or in the rhizosphere where plant roots and soil interact can play crucial roles in plant health. This is of particular… [Read More]
