'''Ethanol''' is an [[alcohol]] [[oxygenate]] that is added to [[gasoline]] to increase the [[octane]] rating. The product is produced through the [[fermentation]] of [[corn]], or other cellulosic material.  

'''Ethanol''' is [[biofuel]] made from [[alcohol]] and is an [[oxygenate]] that is added to [[gasoline]] to increase the [[octane]] rating. The product is produced through the [[fermentation]] of [[corn]], or other cellulosic material.  

A by-product of the fermentation process is [[distillers grains]] which can be used as cattle feed.

 

 

 

 

A co-product of the fermentation process is [[distillers grains]] which can be used as cattle feed. Distillers grains is termed either [[wet distillers grains]] or [[dried distillers grains]] or simply [[DDGs]]. Wet distillers grains have a very short shelf life as they are susceptible to microorganisms that can pollute the material and render it unfit for cattle consumption. 

 

 

In the [[United States]] ethanol is most commonly made through the fermentation of corn. Other countries, such as [[Brazil]] use sugar as a [[catalyst]] for the fermenting process. Currently, the US has the highest production numbers for ethanol in the world, but some analysts forecast China as being a potential world player in the ethanol market. [[China]] currently uses [[casava]] and [[wheat]] among other material for producing ethanol.
