  1. GCSE Biology unit 3 Mycoprotein

  2. Which pairs of pictures go together and why? What is the connection between all 4 pictures?

  3. 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.

  4. What’s in a name? Recap of Scientific Classification Fungi K Kingdom Ascomycota Phylum P Class Sordariomycetes C Hypocreales O Order Nectriaceae Family F Fusarium Genus G S Species F. venenetum F. sporotrichoides Food source! Biological weapon!

  5. 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?

  6. 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

  7. Watch the 1st three minutes of this One Show clip http://www.youtube.com/watch?v=bYGrymywG5c

  8. Using the data above, explain why Quorn could be described as a healthier alternative to meat.
