Optimization of Aerobic Fermentation

As most renewable energy and power companies know, power consumption during aerobic fermentation is one of the major operating costs. At any given point in the process, there are many combinations of airflow and agitation that will give the required mass transfer rate. But the combined power required of the agitator plus the compressor is…

Equipment Requirements to Study Agitation for Gas-Liquid Fermentation

Equipment Requirements to Study Agitation for Gas-Liquid Fermentation by Gregory T. Benz Background and purpose 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…
