• Aseptic precaution
• A pipe steam filled pipe
• fed into the fermenter in between session
• To sterilize the fermenter
• Nutrients
• Nutrients are fed in through pipes
• Can be opened or closed using valves
• Optimum Temperature and PH
• Has a sensitive prob to measure each
• Fermentation produces heat
• Fermenter is surrounded by a water jacket
• to prevent over heating
• water circulates and keeps temperature at the most efficient for growth
• PH can be adjusted by adding acids or alkali
• To keep it constant
• Oxygenation and Agitation
• Stirring paddles
• Stirs content
• located in the center of the fermenter
• Keeps microorganisms in suspension in the liquid
• They get more exposure to the nutrients that are fed in
• Agiation helps keep the temperature even in the fermenter
