This unit discusses food as a habitat, the principles involved in microbiological spoilage of foods, micro-organisms of public health significance that cause food-borne illness, food safety and aspects of food preservation. Microbiological testing of foods is considered using current standard methods. The industrial microbiology section examines how micro-organisms are obtained, handled and maintained in industry and discusses the application of genetically modified micro-organisms. Fermentation modes and kinetic models are discussed using batch and continuous growth. Scale up and downstream processes of industrial fermentations and the role of micro-organisms in producing substances of industrial importance is discussed using antibiotics, hormones, membrane proteins and bioethanol as examples.
On completion of this unit students will be able to:
- Discuss food as a habitat for micro-organisms;
- Describe micro-organisms characteristic to the food industry and their roles in food production, food spoilage and food-borne illnesses;
- Explain principles involved in microbiological spoilage of food, microbial control, and methods of preserving foods;
- Recognise the importance of microbiological food criteria and HACCP systems for maintaining food safety in industry;
- Discuss the use of microorganisms in industrial processes, and providing examples representing the breadth of these applications;
- Describe the principles and applications of batch and continuous fermentation processes;
- Describe the application of industrial control systems such as SCADA for microbial fermentations.
