New tool helps find gene markers in microorganisms

Researchers have devised a novel method to exploit relationships between bacteria and archaea for a new set of gene markers The Science The researchers developed a new way to identify gene markers in bacteria and the primitive microorganisms classified in the kingdom known as Archaea. Dubbed, PhyEco (for phylogenetic and phylogenetic ecology) this strategy can… [Read More]

Subsurface Sediment Yields Novel Organism

Metagenomic analysis emphasizes the “extraordinary microbial novelty” of poorly-explored subsurface ecosystems The Science Through metagenomics, researchers reconstructed a dominant organism and member of a new phylum-level lineage from an aquifer sediment in Colorado. The Impact Analysis of the complete microbial genome led to a detailed metabolic model with evidence for multiple new enzymes and pathways…. [Read More]

Yellowstone yields novel achaeon and candidate Archaea phylum

When a third branch to the Tree of Life was proposed several decades ago, the evidence used to support the need to recognize the kingdom Archaea came in the form of two divisions of organisms that could not be categorized as Eukaryotes or Bacteria. Since then, several more archaeal phyla have been recognized, many of them… [Read More]

Dark ocean project in Climate Action

To understand the world’s climate, we must understand how the 70% of the Earths surface that is covered with water behaves. Very little is known about the processes below 200m, or the area where photosynthesis is not possible due to the lack of light penetration. Scientists from the U.S. Department of Energy Joint Genome Institute… [Read More]

Capturing carbon in the dark ocean

The oceans cover more than half of the planet’s surface, and as such play an important role in the global carbon cycle, trapping 50 times more carbon than the atmosphere. However, the process by which carbon fixation takes place deep underwater where the sunlight does not penetrate has not yet been fully explained. Through single… [Read More]

UCLA microbiologists find energy-efficient structures in archaeon

a type of Archaea known as Methanosprillum hungatei contains incredibly efficient energy-storage structures. The findings are published in the July 5 issue of the journal Environmental Microbiology. M. hungatei is of considerable environmental significance because of its unique ability to form symbiotic relationships with syntrophic bacteria to break down organic matter and produce methane gas. Yet while their important role in… [Read More]

DOE JGI/JBEI collaboration in Green Car Congress

Such salt-tolerant enzymes, particularly cellulases, offer significant advantages for industrial utility over conventional enzymes, they said. The group plans to expand this research to develop a full complement of enzymes that is tailored for the ionic liquid process technology with the goal of demonstrating a complete biomass-to-sugar process, one they hope can enable the commercial… [Read More]

Earth Microbiome Project in Sacramento Bee

To understand microbes (Bacterial, Archaeal, Eukaryal and Viral) in terms of whom they are and what they do is the challenge of microbial ecology. The EMP presents a revolution in how this problem is tackled and defines both questions and potential suite of tools to provide answers.  Key participants in this unprecedented project include BGI,… [Read More]

Syntrophic communities sequencing project on SciGuru

In work published in the advanced online version of the International Society for Microbial Ecology (ISME)’s Journal on August 5, an international team of scientists including DOE JGI researchers report the first metagenome analysis of a microbial community grown in an anaerobic methanogenic (methane producing) bioreactor. The microbial community is syntrophic, i.e., certain organisms live… [Read More]
