NEW YORK, Aug 22 (Reuters) - U.S. ethanol makers lost money this week, after about a month of slim profits, as prices spiked for corn, the country's main feedstock for the alternative motor fuel, analysts said.
U.S. distillers were losing about 10 to 20 cents per gallon for the week ending Thursday, as corn prices rose during the week, analysts said.

"It's not the greatest business right now," said Cory Garcia, a researcher at Raymond James and Associates in Houston, who added that upcoming crop data reports should keep prices volatile for weeks at least.

Prices remained lower than record levels in June above $7 a bushel, brought about by the worst flooding in the Midwest in 15 years that made ethanol producers lose even more money during that time.

Early in the month the U.S. Environmental Protection Agency kept renewable fuel mandates steady for 2008 at 9 billion gallons, rejecting a request by the Texas Gov. Rick Perry to halve the level, which gave some confidence to the industry.
