ZBIO H4101 - Indust Microbiology & Biopharm

Module Title:Industrial Microbiology and Biopharmaceuticals
Language of Instruction:English
Credits: 10
NFQ Level:8
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: This module will be taught as three lectures per week over 30 weeks. The practical element will consist of 30 hours and will include a site visit to an industry of relevance to the course. Any course-related issue or questions that may arise will be discussed at lectures. 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.
Module Aim: The aim of this module is to introduce students to the principles of industrial microbiology, bioprocessing and biochemistry as applied in an industrial context and also to provide the microbiology and cell biology knowledge base for students to successfully enter the pharmaceutical and biopharmaceutical industries.

The practical component will consist of 30 hours in the lab. The sessions will cover practicals/demonstrations of bioprocessing technologies to include the following: the operation of a 16L pilot plant fermenter, demonstration of induction/catabolote repression of a model system for the production of a microbial protein such as β galactosidase in E. coli, demonstration of cell disintegration technologies such as X Press, sonication and toluene treatment, some downstream processing including centrifugation, gel filtration and other chromatography techniques and freeze-drying, with emphasis on yields and process losses, the isolation of an antibiotic-producing organism (polymyxin-producing Bacillus) from soil and its growth to pilot plant scale.
