This workshop’s focus is to provide individuals with an introduction to fermentation concepts in industrial settings. The workshop will be lecture-based with visual aids to help the attendees understand the fermentation principles discussed. The workshop will be broken into sections based upon the topics that are being presented. After each section has been completed, the attendees will be given real life fermentation case studies that they will work through to reinforce the just discussed topics. The first section of the workshop will include topics on fermenter design including aspect ratios, agitator design, sparger design and sterilization of equipment and media. The second section will deal with actual operational issues of fermentation processes. Included will be discussions about media considerations, foam control strategies, shear, mixing, aeration, feeds and different types of fermentations and the controls involved. The workshop will finish with a section that covers issues involved in scale-up to production size fermentors.
