A tree that can reach 90 feet in six years and be grown as a row crop on fallow farmland could provide an additional feedstock for biofuels production.
According to a Purdue University release, researchers Clint Chapple and Rick Meilan (pictured with trees) are using genetic tools in an effort to design trees that readily and inexpensively can yield the substances needed to produce alternative transportation fuel. The scientists are focused on a compound in cell walls called lignin that contributes to plants’ structural strength, but which hinders extraction of cellulose. Cellulose is the sugar-containing component needed to make the alternative fuel ethanol.
Chapple and Meilan want to genetically modify a hybrid poplar tree so that lignin will not impede the release of cellulose for degradation into fermentable sugars, which then can be converted to ethanol. The changed lignin also may be useable either in fuel or other products, they said.


Next week, Purdue University and U.S. Sen. Richard Lugar will host an energy summit to discuss industry and policy perspectives on how our nation can significantly reduce its dependence on foreign oil.

I had the opportunity for a 15 minute interview with Secretary of Agriculture Mike Johanns today in Kansas City. I was wearing many hats, so I had to ask him questions on several topics, but I did get in a question about food versus fuel when it comes to ethanol.
A ground-breaking event will be held Friday in Hankinson, N.D. on August 25 for US Bio Hankinson, the biggest ethanol plant in North Dakota. (
