UNT Researchers Discover Potential New Paths for Plant-Based Bioproducts



DENTON (UNT), Texas -- Plant science researchers at the University of North Texas have found potential new pathways for the creation of plant-based bioproducts. The research is outlined in a new article in the journal Nature Plants.


The UNT research team was working as part of the US Department of Energy's BioEnergy Science Center coordinated by the Oak Ridge National Laboratory.
The team looked into the roles of enzymes that convert amino acids into lignin in Brachypodium, a fast-growing model grass with a sequenced genome. Lignin is a substance that makes plants woody and firm, and, although it is an impediment to the processing of feedstocks for biofuels, it can be used to create a variety of bioproducts, including materials such as carbon fiber.


"As we studied the way different amino acids are converted to lignin, we found that there may be a new and unrecognized pathway for making lignin in grasses," said UNT Distinguished Research Professor Richard Dixon. "A new pathway means potential for engineering more lignin in plants that don't possess that pathway, as well as an additional way of modifying lignin in grasses. This provides new opportunities for the synthesis of high value, high volume bioproducts that could significantly improve the economics of the bioenergy industry."

ORNL licenses AR-CITE software, plant gene technology

ORNL licenses AR-CITE software, plant gene technology

ORNL has entered new license agreements with Foresight Science and Technology and GreenWood Resources. Foresight, a Comptche, California consulting company working with national laboratories and universities, licensed ORNL's AR-CITE copyrighted software and patent application that analyzes scientific literature to identify emerging technology trends. The company plans to use the technology to help partner institutions evaluate technology commercialization opportunities.

GreenWood Resources, a Portland, Ore., timberland investment and asset management company, licensed a patent application based on a gene that regulates phenylpropanoid, tyrosine and tryptophan biosynthesis pathways which can be used to reduce lignin content and increase ethanol yield in biofuels feedstocks.
AR-CITE was developed by Bob Abercrombie, Margaret Lantz, Bob Schlicher and Rick Sheldon. The technology for plant and crops improvements was developed by Wellington Muchero, Gerald Tuskan, Lee Gunter, Sara Jawdy, Anthony Bryan, Hao-Bo Guo, Stephen DiFazio and Jin-Gui Chen. The licenses were negotiated by S&T Partnership's David Sims and Jen Caldwell.

NREL explains the higher cellulolytic activity of a vital microorganism

Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) and the BioEnergy Science Center (BESC) say better understanding of a bacterium could lead to cheaper production of cellulosic ethanol and other advanced biofuels.


Their discovery was made during an investigation into the performance of Clostridium thermocellum. The scientists found the microorganism utilizes the common cellulase degradation mechanisms known today (free enzymes and scaffolded enzyme attached to the cell), and a new category of scaffolded enzymes not attached to the cell.


The discovery came as a surprise to the researchers and explains the superior performance of C. thermocellum on biomass. A paper reporting the potential for the bacterium, "Dramatic performance of Clostridium Thermocellum explained by its wide range of cellulase modalities," appears in the current issue of the journal Science Advances.

BESC study seeks nature's best biocatalysts for biofuel production

Researchers at the Department of Energy's BioEnergy Science Center are looking beyond the usual suspects in the search for microbes that can efficiently break down inedible plant matter for conversion to biofuels.  A new comparative study from Oak Ridge National Laboratory-based center find the natural abilities of unconventional bacteria could help boost the efficiency of cellulosic biofuel production.
