5.8 Fermenter

The fermenter is to keep the optimum growth conditions for the conditions so it will provide the product we demand. 

• Aseptic Precautions  = this prevents pathogens and unwanted bacteria from contaminating the substrates and products
• Optimum temperature = enzymes produced by the microorganism function best at this temperature, so to produce more yield, this temperature is controlled
• pH Levels = enzymes also function best at a certain pH, so this is similarly controlled by the fermenter
• Oxygenation = Oxygen is needed in the reaction since it is aerobic
• Agitation = this ensures that the microorganisms are distributed evenly throughout the fermenter, and prevents clusters of them from forming; also ensures even temperature and nutrient concentration
