What will I learn on this module?

This module will develop your understanding of how microbes pervade the environment and impact the preparation, storage and safety of foods and drinks. You will explore the types of cellular microbes and their metabolism including yeast, filamentous fungi and bacteria. We will also consider the biology of non-cellular infectious agents such as viruses and prions and countermeasures required to prevent food-borne infection. You will explore the microbiology of the human digestive tract in health and disease and distinguish infection with food-borne pathogens from food-poisoning. Additionally, the value of microbes as probiotics will be explored. You will see the impact of culture conditions on food preservation and on laboratory-based tests for food safety. You will culture and qualitatively examine microbes to identify them and will also enumerate these in order to assess risk to human health or product quality. Additionally, you will also learn other quantitative techniques such as bioassays and estimations of microbial inactivation as in, for example, pasteurisation. You will consider the frequency and impact of endospore formation in relation to all of these aspects. Another important and exciting facet of the course will be the rapid detection of microbial products like DNA and antigens using modern molecular analyses rather than traditional culture-based methods.

How will I learn on this module?

You will learn through a linked series of lectures and practical classes. In lectures, the underlying theory and principles of food-related microbiology and analytical methods will be explained and illustrated with real-life examples and applications. You will also gain laboratory experience in the handling, detection, identification, enumeration and molecular analysis of microbes in various food matrices.

How will I be supported academically on this module?

You will be taught by a small team of academics who will deliver lectures and lead practical classes. Each team member will provide support and guidance around the topics they teach. Support regarding the assessments associated with the module can be gained from the module tutor. Staff will be available for discussions in/after timetabled sessions (particularly during practical classes) and appointments can be made at other times to receive support. Your work will be supported by a detailed practical workbook provided by the module tutor and additional resources available through the module space on our e-learning portal.

What will I be expected to read on this module?

Module abstract

This module focusses on the diversity of microorganisms and other microbiological entities (viruses and prions) and the impact that they have on the production, safety, and storage of food and drinks. You will study how the ambient conditions in food matrices inhibits or selects for the culture of important microorganisms and how laboratory culture environments can be manipulated to aid identification of contaminating microorganisms. You will see the value of culture-based analyses of microbial content as well as exploring the principles and applications of more modern rapid molecular-based tests. The teaching and assessment here should equip you to make professional judgements on the type and outcomes of microbiological analyses necessary to promote quality in the food industry.
