- 1. What limewater turns when CO2 is bubbled through it
- 4. Containers used to grow (‘culture’) microorganisms like bacteria and fungi in large amounts
- 8. The production of carbon dioxide in fermentation of bacteria makes this rise
- 9. Stirring... These ensure that microorganisms, oxygen, nutrients and temperature are evenly distributed in the fermenter
