Corn fiber is particularly attractive as a novel source of sugars for ethanol fermentation. Corn fiber has a high carbohydrate content that can be converted into fermentable sugars and is stockpiled at central locations—in many cases at existing fermentation facilities. Currently, most corn fiber is incorporated into low-value animal feeds which may face a limited market in the future as ethanol production continues to grow. In addition to using corn fiber as a feedstock for ethanol, it may serve well as a feedstock for such value-added fermentation products as
lactic acid, xylitol, lycopene, etc. (Leathers 1998). In
addition to the fibrous component of the kernel, the rest of
the corn plant (e.g., corn stover) could also serve as a
feedstock for ethanol (Wyman 2003). Corn stover contains
58% carbohydrates and 1.0–1.5 pounds of stover are
produced per pound of harvested corn. Unlike DDGS and
corn fiber, collecting and storing corn stover represents a
formidable challenge. However, fermenting available corn
stover could conceivably boost ethanol production 10-
fold. To date, no commercial process is in operation for the
conversion of corn fiber or corn stover into fuel ethanol.
