Delft breakthrough in bioethanol production from agricultural waste
Date:11/20/2009

With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol' This week the invention was published in the scientific journal Applied and Environmental Microbiology.

Car fuel

Bioethanol is made by the yeast Saccharomyces cerevisiae from sugars obtained from plant biomass. This microorganism also converts such sugars into ethanol (alcohol) in beer and wine. The production of bioethanol is rapidly increasing due to the growing use of bioethanol as a car fuel. With an annual world production of 65 billion liters, bioethanol is aready the largest product of the fermentation industry

Second Generation

Bioethanol should of course preferably be produced from resources that do not compete with food production. For this reason, efforts are made to produce second-generation bioethanol, using agricultural residues such as wheat straw and corn stover. However, when the sugars from these raw materials are released, significant quantities of acetate are formed. Acetate can slow down or even halt bioethanol production by yeast.

Byproduct

Another challenge of the current bioethanol production process is that about 4% of the sugar is lost to formation of the byproduct glycerol. Glycerol formation was long considered to be an inevitable consequence of the production conditions during bioethanol production.

Yeast genes

TU Delft researchers have now solved these issues. Yeast can, at least in theory, also convert the harmful acetate to ethanol. As it turns out, just one single gene is missing in the yeast. By introducing a single gene from the bacterium Escherichia coli, researchers of the Netherlands-based Delft University of Technology and the Klu
