Some food products are made using biotechnology and microorganisms on an industrial scale.
The table gives information about the production of two of these products.
Complete the table by giving the missing information for (i), (ii), (iii), (iv), and (v).
| Food product | Microorganism used | Group organism belongs to | Main substrate | Type of respiration | Main useful product |
|---|---|---|---|---|---|
| Mycoprotein | (i) | Fungus | Glucose | Aerobic | (ii) |
| Beer | Yeast | (iii) | (iv) | (v) | Ethanol |
An industrial fermenter, like the one shown in the diagram, is used to culture the microorganism needed to produce mycoprotein.
Explain why:
(i) sterile air must be bubbled through the sterile air inlet during the process,
(ii) cold water must be circulated through the cooling jacket.
