Iowa corn growers say they can meet the demand for both food and fuel.

Grower leaders from the Iowa Corn Promotion Board and Iowa Corn Growers Association held a media teleconference Friday to answer concerns about corn prices and supplies and the increasing demand for corn to make ethanol.

Bob Bowman, ICGA president, who farms in DeWitt, said the current uproar over corn supplies is nothing new: “We’ve seen this debate before, as recently as 1995/96. I’m no economist, but I can tell you that when we see strong demand and good prices, corn farmers respond with higher production.”

Both men agreed that the current healthy demand for corn and strong corn prices are good news for Iowa’s growers and the local economies they support because they give farmers an opportunity to be profitable in the marketplace.

Scientists with the Massachusettes Institute of Technology have engineered yeast that can improve the speed and efficiency of ethanol production.

By manipulating the yeast genome, the researchers have engineered a new strain of yeast that can tolerate elevated levels of both ethanol and glucose, while producing ethanol faster than un-engineered yeast.

The new strain produced 50 percent more ethanol during a 21-hour period than normal yeast.

The work is reported in the Dec. 8 issue of Science.

Corn’s role in cellulosic ethanol appears solid.

According to a story in Illinois Farm Bureau’s FarmWeek, the push to promote “cellulosic” biomass ethanol development generated some early sparring between corn growers and proponents of new “energy crops.”

Corn-based cellulosic potential should grow with efforts to boost per-acre grain yields to meet future energy, feed, and export demand, said Rod Bothast, scientist with Ed­ wards­ ville’s National Corn-to-Ethanol Research Center.

Senator Byron Dorgan (D-ND) told a recent ethanol summit in his state that with new ethanol plants coming on line at a rapid pace, the use of ethanol needs to grow or we could soon end up producing a surplus of ethanol.

According to a story in the Farm & Ranch Guide by reporter Dale Hildebrant, Dorgan said, “Our future is not in a 90-10 blend. If it’s only a 10 percent ethanol blend we are going to produce more than we need and we are going to run into a problem here. We need to address how do you put a higher blend into these vehicles that Detroit has made and is going to make, so we can consume a substantial amount of additional renewable fuels and displace that which we need to bring in from foreign sources of oil.”

Dorgan also noted that more consumer education is needed showing that using ethanol won’t harm a vehicle’s engine.

But the auto industry has two concerns they need to address: the first is developing engines that burn higher blends of ethanol more efficiently; and then to address the liability issue for those not owning flex-fuel vehicles, but still desire to burn ethanol blends greater than 10 percent. That liability problem is what is preventing some service stations from offering higher blends, but Dorgan said rewriting liability waiver legislation would be difficult to do.

Research being done at Washington University in St. Louis could result in more efficient ethanol production.

The research by adjunct professor of biology in Arts & Sciences Erik E. Nielsen, Ph.D. was published in a recent edition of The Journal of Cell Biology, according to a news release.

Nielsen’s research is the first to identity some of the membrane trafficking steps in the deposition of cell wall components — a lightly researched area. His study is important because cotton, wood and other plant fibers that are vital to everyday life rely on the plant cell wall, which gives wood the strength needed for construction and furniture, among other uses, and cotton fibers the elasticity for use in cloth. The research could lead to crops with stalks that can be used to produce biofuels more efficiently and with less waste.
