5.8: Interpret and Label a Diagram of an Industrial Fermenter and Explain the Need to Provide Suitable Conditions in the Fermenter, Including Aseptic Precautions, Nutrients, Optimum Temperature and pH, Oxygenation and Agitation, for the Growth of Micro-Organisms

INDUSTRIAL FERMENTER: Where Reactions using Microorganisms to Make a Range of Food Products and Medicines, Enzymes and Fuels takes Place in a Controlled Environment

Diagram:

                              

 SUITABLE CONDITIONS:

CONDITION	EXPLANATION
ASEPTIC PRECAUTIONS	Fermenter is Cleaned by Steam to Kill Microorganisms and Prevent Chemical Contamination, Only allowing Desired Microorganisms to Grow
NUTRIENTS	Nutrients are needed to be Used in Respiration to Release Energy for Growth, allowing Reactions to Take Place
OPTIMUM TEMPERATURE AND pH	Optimum Temperature and pH is Maintained using Probes to Ensure an Optimum Environment for Enzymes to Increase Enzyme Activity (Enzyme Denatures if Temperature and pH is Too High)
OXYGENATION	Oxygen is Needed for Aerobic Respiration to Take Place as Most Reactions are Aerobic
AGITATION	Stirring Paddles Ensures that the Microorganisms, Nutrients, Oxygen, Temperature and pH is Evenly Distributed
