ETHANOL YEAST Ethanol is a fuel additive which is used to improve gasoline combustibility. Most look at ethanol as the best solution to the ever growing oil driven energy crisis. There have been some problems in the manufacturing of ethanol. One being high ethanol levels being toxic to the yeast that ferments corn and other plant material used in the making of ethanol. Recently, by manipulation the yeast genome, researchers have engineered a new strain of yeast. |

Raising the efficiency has been the main focus for ethanol researchers and producers.
This high tolerance this ethanol yeast displays, proved to be much more rapid in the fermentation process. In fact the new ethanol yeast produced approximately 50 percent more ethanol during a 21 hour period than the normal yeast previously used.
Using this approach to engineer similar tolerance traits in industrial yeast, could dramatically impact ethanol production. This is a multi stop process. Cornstarch or another source of glucose is broken down into single sugar molecules, this is done by enzymes. This is when the yeast ferments the glucose into ethanol and carbon dioxide.
These developments in manufacturing and technology of ethanol, with the use of yeast, improves ethanol, making it much more attractive for not only consumers, but producers as well.
More efficient, and cost effective, makes ethanol yeast valuable in the production of ethanol
