Golden image of corn-based ethanol shows some erosion

CLAREMONT, Minn.

Market changes and a growing chorus of concerns about ethanol make Doyal and other ethanol supporters question how long the good times will last. Corn prices, though down lately, remain high at $5.98 a bushel, making it harder for ethanol producers to profit. Livestock producers blame the ethanol industry for driving up feed prices and fueling food inflation for consumers.

Industry supporters say opponents are overstating the impact of ethanol on food prices and ignoring other factors in driving up food costs
