DuPont Industrial Biosciences is looking into understanding the yeast metabolism and dynamics associated with various stresses in the fuel ethanol fermentation process.
“Those stresses could be putting in too much enzyme, or not enough enzyme,” said Dr. Donald Cannon, who presented at the Corn Utilization and Technology Conference. “So, we’ve identified succinate as a marker for nitrogen stress and what we’re using that for is to help in protease trials.”
Cannon says they believe these metabolite insights will be helpful as ethanol plant technology diversifies. “Increasing efficiency and taking care of process upsets,” he explained. “What we want to be able to do is help plants identify those upsets.”
