Equipment Requirements to Study Agitation for Gas-Liquid Fermentation

April 17, 2018 |

By Gregory T. Benz, Lee Enterprise Consulting Special to The Digest Small pilot fermenters are used with several different objectives: studying the organism, developing feeding strategies, evaluating potential yields, etc. A major purpose can be to study the mass transfer characteristics of the system, and how they relate to agitation. In the production scale, the […]

Keeping yeast fit and healthy: combating organic acids in fermentation

Keeping yeast fit and healthy: combating organic acids in fermentation

October 23, 2017 |

By Amanda Moser, Senior Scientist, Novozymes Special to The Digest It’s harvest time, and that means organic acids—a common stressor for yeast—are a top-of-mind concern for ethanol producers. But while some yeasts are more resilient than others, most still require constant attention; after all, each stressor can potentially reduce performance, and those reductions can quickly […]
