Fermenters are big steel vessels, in which microorganisms are grown.
Inside they are provided with exactly the right conditions to encourage them to grown and produce the substances we require.
- Penicillium is used to produce penicillin
Before the microorganism is put into the fermenter it must be sterilised using high pressue steam to kill any miccroorganisms that might grow instead and cause competition for nutrients etc
Everything added to the fermenter is also sterilised
This is aseptic precautions
