reasons for using microorganisms

• grow easily and rapidly, grow well at low temperatures

• genetically engineered to produce desire products

• food processes such as brewing, baking, cheese making

low cost

• requires low temperatures

• low energy requirements

• nutrients are cheap

high yield of product

• reproduce quickly

• short generation time (rapid doubling time)

less pollution/better for environment

• low energy requirements

• reduces use of land for food production

disadvantages

• can produce harmful toxins

• doesnt taste good

• process involes sterilisation, purification and separation which adds cost
