topic 7: using microorganisms
Section 5: Use of biological resources a) Food production
5.6 describe a simple experiment to investigate carbon dioxide production by yeast, in different conditions
5.5 understand the role of yeast in the production of beer
5.7 understand the role of bacteria (Lactobacillus) in the production of yoghurt
5.8 interpret and label a diagram of an industrial fermenter and explain the need to provide suitable conditions in the fermenter, including aseptic precautions, nutrients, optimum temperature and pH, oxygenation and agitation, for the growth of micro-organisms.
5.14 understand that large amounts of human insulin can be manufactured from genetically modified bacteria that are grown in a fermenter
