Derek Payne talks fermentation, maximization, and optimization
Derek Payne is a Senior Research Associate for Novozymes and can now add “speaker at the Fuel Ethanol Workshop and Expo (FEW)” to his résumé. Payne’s topic was aptly titled “Yield Maximization: Propagation and Fermentation Optimization” and was presented on June 2, 2015.
According to Payne, laboratory-scale fermentation—one of the tools from Novozymes’ service portfolio—offers a number of advantages over large-scale or even pilot scale fermentations. His talk built the case for employing laboratory-scale ferrmentation, the challenages of scaling, and the predictive quality the method can have when an ethanol plant overcomes said challenges.
“Laboratories are very powerful tools,” said Payne. “They can produce copius amounts of data quickly with diverse experiemntal design at a relatively low cost. They’re great for troubleshooting as you can pinpoint different toubles that you’re having in your fermentations and also then look for solutions and test those solutions to see if you can fix those troubles.”
“They’re great for testing new products and technologies at lab-scale before you implement them in industry-scale,” continued Payne. “[This] allows you to save time and money.”
However, there were challenges to translating all of your plant processes into the laboratory. For example, Payne explained that yeasts are complex organisms susceptible to many factors that can affect yeast performance.
“This is just one of the many factors that affect your fermentations,” said Payne. “However, I do believe that if you set up an effective design experiment, you can overcome these challenges and run effective fermentation that can bring value to your process.”
Payne was one of four members of the Novozymes team who presented at the conference.
