Fermentation Facility Assists DuPont Pioneer with Research Project

DuPont Pioneer used the Iowa State University Fermentation Facility to work on a research project involving bacterial fermentations. A preliminary fermentation was conducted using the 50-liter fermentor to determine scale-up feasibility. The main fermentation was conducted in the BioCentury Research Farm’s biochemical processing train using the 500-liter fermentor. The semi-continuous centrifuge was used for downstream processing.

Besides using the equipment, DuPont Pioneer researchers also received technical assistance from Zhiyou Wen, Fermentation Facility professor-in-charge, and John Strohl, Fermentation Facility manager. Strohl trained the researchers in use of the fermentors and other equipment.

DuPont Pioneer, headquartered in Des Moines, Iowa, is the world’s leading developer and supplier of advanced plant genetics, providing high-quality seeds to farmers in more than 90 countries.
