ZBIO H3102 - Fermentation & Food Microbiology

Module Title:Fermentation and Food Microbiology
Language of Instruction:English
Credits: 10
NFQ Level:7
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: The module will be taught as two theory classes of one hour duration and one two hour practical session over thirty weeks. Course lecture summaries, course calendar, announcements and other course-related information will be available on Blackboard, a virtual learning environment. Students can contact lecturer outside of class hours to discuss formative feedback given on written reports and group project work. The practical component will • allow students to develop the required technical competencies, attitudes and behaviours • develop problem solving abilities and group skills • promote learning via investigation of a problem, application of prior knowledge and analysis of results thus generating new knowledge • promote timely submission of reports written in the standard format
Module Aim: The aim of this module is to introduce students to the microbiology of food and microbial physiology.

Module Content & Assessment

Indicative Content
Food Microbiology
The role of microbiology in food preservation and food spoilage. Microbiological aspects of food processing. Methods of food preservation, including the use of asepsis, removal of microorganisms; filtration, heat, drying and anaerobic conditions. Heat preservation methods including canning, pasteurisation, and other heat treatments and the theory of heat sterilization. Food and microbial preservation by low temperatures, including refrigeration, freezing, lyophilization, blast and cryogenic freezing. Food preservation by drying. Chemical additives as food preservatives.
Food Borne Illnesses
Food borne illnesses are studied in terms of the properties of the microorganisms themselves, the mode of entry and behaviour in food, the types of foods involved, toxicology and symptoms and the methodologies used in each case. Food borne infections, including Salmonella, E coli, Shigella, Vibrio, Listeria and Campylobacter. Food borne intoxications, including Staphylococcus aureus and Clostridium botulinum. Other food borne illnesses including Bacillus cereus, Clostridium perfringens and illness passed on by food such as Brucella abortis, Mycobacterium tuberculosum and Trichinella. Virus infections passed on by foods. Mycotoxins.
Milk microbiology and fermentation.
Microbial contamination of milk and milk products. Microbial quality control issues in milk production and processing. The production of fermented milk products. Properties of starter cultures. Mastitis and other milk borne diseases and their health and economic implications.
Fungi and Viruses
An introduction to the most important groups of fungi used in the food and biotechnology industries. Fundamentals of brewing and ethanol production. An introduction to the biology of viruses with particular emphasis on the importance of phage in starter production. Control of phage in the cheese industry
The practical element of the course will consist of 30 two hour practicals covering the identification and isolation of the main groups of microorganisms involved in the food industry and also food fermentation.
