What is biotechnology?
The use of living organisms or biological processes to produce useful products.
What is mycoprotein?
A protein-rich food produced using a fungus.
Which type of organism is used to produce mycoprotein?
A fungus.
What is the name of the fungus commonly used in mycoprotein production?
Fusarium venenatum.
How is mycoprotein produced?
The fungus is grown in a fermenter and its biomass is harvested and processed into food.
What is a fermenter?
A vessel used to grow microorganisms under controlled conditions.
Why is glucose supplied during mycoprotein production?
It provides a source of carbon and energy for respiration and growth.
Why are mineral ions supplied to the fungus?
They are needed for growth and the synthesis of biological molecules.
Why is a nitrogen source needed for mycoprotein production?
Nitrogen is required to make amino acids and proteins.
Why is oxygen supplied to the fermenter?
To support aerobic respiration by the fungus.
Why must the fermenter temperature be controlled?
To maintain suitable conditions for enzyme activity and fungal growth.
Why must the fermenter pH be controlled?
To maintain suitable conditions for enzymes and metabolism.
Why is the fermenter stirred?
To distribute nutrients, oxygen and heat evenly.
Why must contamination be prevented during mycoprotein production?
Other microorganisms may compete for nutrients or contaminate the product.
How is the mycoprotein harvested?
The fungal biomass is separated from the growth medium.
Why is mycoprotein useful as a food source?
It provides protein without requiring animals to produce it.
How can mycoprotein contribute to food security?
It provides an alternative protein source that can be produced under controlled conditions.
What is one advantage of producing mycoprotein in fermenters?
Production can occur throughout the year under controlled conditions.
What is one limitation of mycoprotein production?
Fermenters require energy, equipment and a supply of nutrients.
