Synopsis

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:

  1. Discuss food as a habitat for micro-organisms;

  1. Describe micro-organisms characteristic to the food industry and their roles in food production, food spoilage and food-borne illnesses;

  1. Explain principles involved in microbiological spoilage of food, microbial control, and methods of preserving foods;

  1. Recognise the importance of microbiological food criteria and HACCP systems for maintaining food safety in industry;

  1. Discuss the use of microorganisms in industrial processes, and providing examples representing the breadth of these applications;
