University of Kentucky-led research could be path to new energy sources

12.07.2011
A team of researchers led by University of Kentucky College of Agriculture Professor Joe Chappell is making a connection from prehistoric times to the present that could result in being able to genetically create a replacement for oil and coal shale deposits. This could have fundamental implications for the future of the earth's energy supply.

Tom Niehaus, completing his doctorate in the Chappell laboratory; Shigeru Okada, a sabbatical professor from the aquatic biosciences department at the University of Tokyo; Tim Devarenne, a UK graduate and now professor of biochemistry and biophysics at Texas A&M University; and UK colleagues, Chappell, David Watt, professor of cellular and molecular biochemistry (College of Medicine) and his post-doctoral associate Vitaliy Sviripa had an important paper published today in the Proceedings of the National Academy of Sciences (PNAS). Their research findings go well beyond the basic science dealing with the origins of oil and coal.

While scientists previously established that oil and coal have their roots in the organisms that lived on the planet over 500 million years ago, researchers only are sure of one organism that directly contributed to these natural resources. That organism is the algae Botryococcus braunii which left behind its chemical fingerprints – an oil that over geological time has turned into oil and coal shale deposits.

"Even more exciting is that this unique algae, B. braunii, still exists today and has been the target of studies from the large chemical and petrochemical industries," said Chappell.

This algae is very slow growing, so it is not necessarily a good source for biofuels. However, if scientists can capture its genetic blueprints for the biosynthesis of these high value oils, then these genes could be used to generate alternative production platforms.

This team of investigators isolated the necessary genes, characterized the biochemical traits encoded by these genes, and then genetically engineered yeast to produce this very high-value oil. This work has provided the first example of recreating a true direct replacement for oil and coal shale deposits.

Chappell said, "This represents the culmination of an outstanding effort to understand a fundamental process that has direct ramifications for a real-world problem — how are we going to generate a truly renewable biofuel supply?"

Devarenne added, "This study identifies a very remarkable molecular mechanism for the production of hydrocarbons that, as far as we can tell, is not found in any other organism. Thus, it offers a unique insight into how hydrocarbons were produced hundreds of millions of years ago."

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
