Subject Overview:

AIMS

Understanding of: basic microbiology, cell structure and nutritional requirements. Products from microbes and bioprocesses, enzyme kinetics, cell growth kinetics and product formation. Product separation methods.
This subject introduces students to the area of bioprocessing, an area growing in importance in the process industries.

INDICATIVE CONTENT

Enzymic process. Michaelis-Menten approach. Kinetics of enzyme inhibition. Immobilised enzymes. Batch microbial growth and product formation. Continuous culture. Microbial growth kinetics. Application of Monod model to batch and chemostat culture. Kinetics of product formation. Maintenance energy and endogenous respiration. Design of fermentation processes. Medium formulation and inoculum preparation. Industrial sterilisation processes. Calculation of sterility level. HTST sterilisation. Design of continuous sterilisers. Air sterilisation. Vessel design for aseptic operation. Fermenter design configurations. Aeration of fermenters. Oxygen requirements of microorganisms. Mixing in fermenters. Biochemical separation processes.

Practical work (Microbiology laboratory).

Learning Outcomes:

INTENDED LEARNING OUTCOMES (ILO)

On completion of this subject the student is expected to:

  1. Describe the biological and kinetic concepts underlying bioprocesses engineering.
  2. Describe procedures for the design and control of industrial scale fermentation and biological waste treatment processes.

Assessment:
  • One three-hour examination at the end of semester (70%). Intended Learning Outcomes (ILOs) 1 and 2 are addressed in the examination. The examination paper will consist of problems designed to test whether the student has acquired the ability to apply fundamental principles to the solutions of problems involving bioprocesses. The problems set for the exam will be similar in style to those undertaken in the tutorial classes, but will require the student to show that they can extend themselves beyond the level of the simpler tutorial problems
  • One written assignment of no more than 2000 words (20%). Time commitment of approximately 25 -30 hours of work. ILOs 1 and 2 are addressed in the written assessment
  • Two practical work assignments not exceeding a total of 1000 words. (10% total - 5% each). Total time commitment of approximately 13 - 15 hours of work. ILO 1 is assessed in the practical work.

Hurdle requirement: A grade greater than 50% in the exam is required to pass the subject
