Fusarium venenatum is a type of fungus with a high protein content. It is used to produce a food source – mycoprotein – also known as Quorn.

Fusarium sporotrichoides is a type of fungal pathogen which was used to produce a biological weapon. The Soviets were accused of using this weapon, dubbed “yellow rain”, to cause over 6,000 deaths in Laos, Kampuchea, and Afghanistan between 1975 and 1981.

slide5

You only need to know about Fusarium venenatum and its role in producing mycoprotein!

Research activity

What is mycoprotein?

What are the health benefits of eating mycoprotein?

What other benefits of mycoprotein are there?

How is mycoprotein produced?

slide6

Temperature, pH, nutrient and O2 levels are continuously monitored

Nutrients such as potassium and magnesium are added

The fermenter is sterilised and filled with a water and glucose solution.

___

Aerobic conditions

Then a batch of the fungi Fusarium is introduced

The fungi and the nutrients combine to form mycoprotein solids which are removed continuously from the fermenter
