Basic Functions of a Fermenter

• It should provide a controlled environment of optimum biomass yields.
• It should permit aseptic fermentation for a number of days reliably and dependably, and meet the requirements of containment regulations Containment involves prevention of escape of viable cells from a fermenter or a downstream processing equipment into the environment.
• It should provide adequate mixing and aeration for optimum growth and production, Without damaging the microorganisms.
• The power consumption should be minimum,
• It should provide easy and dependable temperature control.
• Facility for sampling should be provided.
• It should have a system for monitoring and regulating pH of the fermentation broth.
• Evaporation losses should be as low as possible.
• It should require a minimum of labour in maintenance, cleaning, Operating and harvesting operations.
• It should be suitable for a range of fermentation processes. But this range may often be restricted by containment regulations.
• It should have smooth production internal surfaces, and joints should be welded wherever possible.
• The pilot scale and production stage fermenters should have similar geometry to facilitate scale-up.
• It should be contrasted using the cheapest materials that afford satisfactory results.
• There should be adequate service provisions for individual plants.
