The vision isn’t to strip the fields bare, but to extract a minor portion — around 20 to 25 percent — of the corn stover for ethanol production.

With this battle-tested version of GRE2, the researchers found that the modified baker’s yeast could produce ethanol from treated corn stover almost as efficiently as from corn kernels.

This strain resolves a key challenge in fermenting ethanol from fibrous materials like corn stover, Balan says.

Converting inedible corn stover into ethanol could increase the biofuel supply without having to plant more crops.

The new strain may benefit biofuel producers trying to harness materials like corn stover, he says.

"Sure," said Stover, sounding the coins in his change pocket.

Stover plunged his hands in his trousers pockets and gazed awed.

Stover began to whistle, keeping an eye on the windows as they approached.

"Tough McCarty and a female," said Stover in great indignation.

"Please, sir, I put asafetida in the furnace," said Stover in frightened tones.
