The Latest News:  the Purdue Yeast is used to produce

Cellulose Ethanol now

 

This past April (21 April, 2004), Iogen Corporation announced that it is producing the world’s first cellulosic ethanol fuel for commercial use (Iogen news release) (Business Week).  Dr. Ho’s recombinant glucose/xylose co-fermenting yeast (widely known as the Purdue Yeast) was used for the production of Iogen’s cellulose ethanol (Purdue news release).  Dr. Ho salutes Iogen for taking this giant step for the cellulose ethanol industry, proving that production of clean, renewable cellulose ethanol fuel is no longer a dream but a reality now!

 

Dr. Ho would like the US also to use the Purdue Yeast to produce cellulose ethanol soon.  The Purdue glucose/xylose co-fermenting yeast has now been validated to be the best and only microorganism suitable for cellulosic ethanol production by Iogen and other major ethanol producers, including the world’s largest grain ethanol producer, Archer Daniels Midland (ADM) (Dr. Abbas’ letter to Dr. Ho).

 

Dr. Ho is committed to doing everything within her grasp to help expedite cellulose ethanol production in this country.  According to very conservative estimates, from 30% of the corn stalks left in the cornfields alone, this country can produce at least 4 to 5 billion gallons of additional ethanol annually.  This material will otherwise be wasted away in the fields as it has traditionally been. We simply cannot afford to waste these natural resources.  In addition, production of additional ethanol from the corn stalks would stimulate the rural economy and provide high paying jobs in the corn producing states.  The same is true for other types of agricultural residues and cellulosic resources (feedstocks).
