Biotechnology
Bayani Gaba-gaba
Long before anyone understood DNA, humans were using living organisms to make food: yeast to raise bread and brew alcohol, microbes to make cheese and yoghurt. Today the same idea, harnessing enzymes and microbes in industry, produces biofuels, clearer fruit juice, cleaner laundry and lactose-free milk, often in giant steel fermenters.
In this lesson you will describe the role of anaerobic respiration in yeast for biofuels and bread, the use of pectinase, lactase and the enzymes in biological washing powders, and (for [Supplement]) how fermenters mass-produce insulin, penicillin and mycoprotein under carefully controlled conditions.
Manufura
- Describe the role of anaerobic respiration in yeast during the production of ethanol for biofuels
- Describe the role of anaerobic respiration in yeast during bread-making
- Describe the use of pectinase in fruit juice production
- Investigate and describe the use of biological washing powders that contain enzymes
- [Supplement] Explain the use of lactase to produce lactose- free milk
- [Supplement] Describe how fermenters can be used for the large-scale production of useful products by bacteria and fungi, including insulin, penicillin and mycoprotein
- [Supplement] Describe and explain the conditions that need to be controlled in a fermenter, including: temperature, pH, oxygen, nutrient supply and waste products
